Fastening MDF panels to the wall without slats. Installation of MDF panels: two methods of fastening wall panels to walls Fastening MDF panels to a wall without a frame

Today one of the simplest and most labor-intensive methods The implementation of beautiful and smooth wall cladding is the installation of MDF panels. This material has won favor due to its low cost and non-toxicity, as well as ease of fastening. The work requires only accuracy and precision.

Frame method of fastening panels

In practice, three methods are applied to the base: on wooden frame, metal profile lathing and adhesive composition.

Wall insulation

When covering the walls with panels, it would be a good idea to additionally insulate them by filling the sheathing chambers thermal insulation material. In addition to insulation, it provides protection against condensation in the space between the base and the casing.

In summer, the heat gain in the room will significantly decrease, and in winter, heat loss will correspondingly decrease, thereby allowing significant savings on payments for heat energy consumption.

Installation of wooden sheathing

Frame installation technology wooden slats Unlike metal sheathing, it’s easier. For its construction, a smaller number of fasteners are used, however, the lathing requires special antiseptic treatment and the cost of wooden boards is higher than the cost of a metal profile.

The frame installation process consists of several stages:

1. Marking the location for fixing the first lathing strip. It should be located perpendicular to the length of the fixed panel slats. That is, if the panel slats are attached horizontally, then the sheathing strips should be positioned vertically, and if the laths are attached vertically, then the grille should be positioned horizontally.
2. Fastening the starting parts of the grid. The place on the base with the largest protrusion is determined; all other frame planks will be aligned to this beacon. The installation of slats should begin with a row passing through the found protrusion on the base. Holes for self-tapping screws are drilled on the bar in increments of 50-60 cm. It should be noted that the more lumpy the wall, the smaller the step should be. Apply a strip to the holes on the wall exactly horizontally and mark the locations of the holes for the dowels (it is advisable to use a level). Then the plank is removed from the wall and, using a hammer drill, holes are drilled in the base and plastic dowels are placed. Subsequent planks of the frame row are fastened in a similar way. To make it easier to align the row slats, you can stretch a bright thread along the starting strip, the ends of which are secured with dowels in opposite corners of the room.
3. Making subsequent rows of sheathing. The first plank of the next row should be located in the same vertical plane with the plank of the previous row. To check, you can use a level applied to the slats of the adjacent rows. If necessary, you can adjust the fastening of the bar by placing small wedges under it. Then the thread is pulled again, acting as a beacon. All rows of the sheathing are performed in this sequence. The distance of the slats between adjacent rows should not be less than half a meter. Installation horizontal strips carried out in the same sequence, in increments of 40-60 cm, in this way the casing will not sag. For subsequent installation of ceiling and floor skirting boards rows of planks should be placed along the ceiling line and flooring of the room.
4. In all corners of the room, on each wall adjacent to one another, vertical planks are attached at right angles.
5. Installation of wooden slats around the perimeter of openings for windows and doors.

Installation of a metal frame

For installation of metal sheathing use metallic profile and connecting fasteners. The products are fixed to the base using self-tapping screws; their length depends on the strength of the base. For the frame, two types of metal profiles are used: narrow (UD) and wide (CD).

The metal frame is made in the same way as the wooden one: racks in the corners and openings, as well as crossbars.

The pitch of the frame is similar to that of the wooden sheathing.

The technology for making a metal frame is as follows:

1. Installation of narrow profiles in corners, around the perimeter of doors and window openings, and also every three meters. This length corresponds to the length of the support post. All intermediate components will be placed in these racks. Fixation should be carried out firmly in increments of 15-25 cm.
2. Horizontal posts are connected to the horizontal profile using longitudinal CD connectors.
3. The key profiles are placed with their ends on the edge into the guide profiles and reinforced with self-tapping screws for strength.
4. If the length of the base on which the casing will be attached is more than two meters, then in order to avoid bending of the profiles from the load of its own weight, it is necessary to additionally secure the fastening brackets.

The edges of the brackets are bent at right angles and in this form are placed in the place where the profile is installed. After fixing the profile in the guides, the brackets are fixed to it with bent parts, and their excess part is cut off. Before final fastening of horizontal posts, it is mandatory to check the horizontal position with a level. If there are any errors, they can be corrected at this stage of installation.

Fastening panels

Installing the trim on the frame is much simpler than the preliminary work. The panels can be installed from any corner of the room.

1. The MDF coating is attached in the following order: Marking and cutting the starting panel.
2. Using a tape measure, measure the required length of the panel, marking it accordingly. Using a jigsaw, saw off the excess part and the tenon that runs along the entire length of the panel.
3. Cutting holes in the casing for lighting fixtures. Attaching the original panel.
4. The canvas is applied to the attachment point in such a way that its back side is adjacent to the sheathing. The side adjacent to the corner at a distance of 1 cm from its edge is attached to all frame slats with self-tapping screws. On the groove side, the panel is secured with metal clips (clasps) so that its protrusion fits into the groove of the panel, firmly fixing it. The clips are attached to the frame slats using nails. Installation of subsequent paintings. Cut off required length covering, then place its tenon in the groove of the previous panel and attach it to the frame using clips. In the same way, all subsequent panels installed before opposite corner
5. walls. Often, the last canvas does not fit completely, so it is adjusted to the required size. Only the piece that is on the tenon side is needed, so the piece of fabric with the groove is cut off. Next, the tenon is inserted into the groove of the previous panel, and the part of the panel that abuts the frame of the adjacent wall is fixed with nails to the sheathing strips. In this sequence, all walls of the room are decorated with canvases. Installation of ceiling and floor plinths.
6. Fastening skirting boards can be done in several ways: using fasteners, using self-tapping screws and using glue. The final stage of installing the panels is the installation of the finishing corner, which covers all coverings. To do this, apply a thin layer to the measured length of the corner. glue mixture

, apply it to the corner part of the walls and gently but firmly press it. To evenly distribute the glue, using a rag, you can walk along the length of the corner several times from the bottom up and back.

Glue installation

This fastening method is suitable when the surface of the walls does not have unevenness or the task is to carefully level them. Also, installing panels with glue is necessary when the wall surface is tiled.

Installation in this way does not require the construction of any frame. First of all, let's decide on the type of glue that is suitable for this type of work.

• Any glue will not work in this case; you need a composition that has certain properties:
• plasticity not only during operation, but also after hardening (the composition must withstand temperature fluctuations);

thick texture so that it can be applied not only in a thin, but also in a thick layer (in this case, construction adhesive - liquid nails - is perfect).

1. The installation technology includes several stages:
2. Cleaning the base surface of old coating, dust, dirt and deposits, followed by processing of the primer mixture.
3. While the primer layer dries, you can cut the panels to the required size.

After the soil has dried, you can begin installing the panels. To do this, large drops of glue are applied to it pointwise in a checkerboard pattern. Then the canvas is pressed tightly against the wall, after which it is torn off, this is done in order to weather the glue, and also to ensure that the sheathing does not lag behind the base under the weight of its weight. After 5-7 minutes, the canvases are applied to the wall and pressed tightly.

• This installation method has several disadvantages:
• from the effects of temperature changes when changing seasons, the cladding may swell or, in the worst case, peel off;

1. when changing the finish, it will be necessary to clean the base from glue residues, as well as the inability to reuse the dismantled panels. If the room in which it is planned to finish MDF has traces of dampness
2. , swelling or peeling of the putty, before cladding it is imperative to remove the old coating to the permanent base.
3. Experts recommend attaching the covering to the frame, even though the profile reduces the space of the room.
4. This is due to the fact that the cladding has additional ventilation and is less susceptible to seasonal fluctuations in temperature and humidity compared to the adhesive method.
5. When installing the sheathing, you can use two types of materials, constructing a base around the perimeter from a metal profile, and the transverse elements from wooden slats.
6. Wooden slats for the frame must be well-dried and even. Due to the fact that MDF is a highly flammable material, care should be taken to ensure that all external electrical wiring is stored away. corrugated pipe
7. for cables, and sockets and electrical switches in boxes. MDF cladding is essentially thick pressed cardboard and, accordingly, is susceptible to moisture.
8. Therefore, prolonged exposure to moisture on the surface will lead to delamination and swelling of the coating.

Professionals advise that during the installation of the sheathing, transfer the location of the planks on the base onto paper with exact adherence to the coordinates. This will make it possible in the future to place any interior items on the wall exactly at the place where the slats are attached, and not on the sheathing, on the surface of which it is strictly forbidden to attach anything. Wall decoration consists of several stages. Installation of MDF on walls will require preliminary selection. necessary materials The technology for installing MDF panels on walls is quite simple.

, if you follow the tips and recommendations. Everyone can arrange a room.

Every person wants to have stylish and comfortable housing to emphasize their individuality and create a unique atmosphere.

Description of MDF wall panels

Installation of MDF boards on walls can be done correctly, quickly and cheaply, without putty, primer, painting or wallpapering. Minimum construction waste, stylish and practical.

Wall panels have been known for more than 10 years on the Russian market. During this period, their popularity has not subsided.

• The advantages of using MDF panels are:
• wide selection of sizes and textures, glossy and matte;
• low cost;
• excellent quality;
• environmental friendliness of the materials from which the panels are made;
• optimally suitable sizes;
• ease of adaptation for premises of any configuration;
• Possibility of attachment to wooden and metal sheathing;
• indicators of mechanical, thermal and ultraviolet resistance;
• long service life without loss of its original appearance;
• resistance to tobacco smoke;
• ease of installation if you need to mount MDF panels on the wall. You can repair a room in half a day, without dust, dirt, preliminary work and large number special tools.

This building material Suitable for both dry and wet areas. Even when exposed to moisture, MDF furniture will not become covered with mold or mildew. Mounting it in wood will also be an advantageous way to decorate the surface.

There is a wide variety of MDF panel designs:

• matte;

• glossy;

Large format ceramic slab effect

Some tile panels small size. I alternate tiles, different in texture and color, so you can lay out different patterns of any level of complexity.

Visually this will achieve the effect ceramic tiles large format.

Thanks to the panels with dimensions of 120 by 80 cm, it is possible to cover the panels faster. Having studied the recommendations on how you can give an excellent appearance modules.

Difference wall panels noted according to such indicators as:

• dimensions;
• texture;
• thickness;
• color;
• fastening principles.

If the work is done correctly, you can create perfect interior. Interior decoration walls with natural materials are now in trend. However, natural materials are quite expensive, and working with them is labor-intensive. Therefore, synthetic materials are widely used.

Thanks to high quality they are difficult to distinguish from natural analogues. MDF panels repeat the texture natural wood, create the appearance of a wooden covering.

At the same time, they are easy to wash and clean. And the installation process is characterized by simplicity and speed of work. It is necessary to cut the panels to the required length and secure them to the frame.

MDF is resistant to moisture. about moisture-resistant MDF for walls. There are special corners to match the color of the panels; they can change shape. With them you can build a platband, internal or outside corners. This kind of material used to give the interior a finished look. You can learn how to install MDF panels on walls from the recommendations.

If the installation is carried out in winter time, you must first keep the wall panels indoors for several days so that they regain their size. When choosing panels, keep in mind that the narrower they are, the longer the work will take, but there will be less scrapping.

It is necessary to determine how much smooth walls. If the level shows good data, then there is no need to make a wooden sheathing.

You can simply glue them to the cement using special glue. If the walls are not level, you will need to do lathing.

This situation is more common. What materials will be needed for it? The sheathing is made from soft wood. Preliminarily think about what kind of sheathing will be. In dry rooms it is better to use wood, and in wet rooms it is better to use a metal profile. It is necessary to select fasteners based on the same parameters.

Self-tapping screws - if a metal profile is used, fasteners made from wood screws or staples, if you need to work on a wooden sheathing. In the space of walls and sheathings you can lay a layer of heat or sound insulation.

How to attach the MDF panel to the wall:

• with lathing;
• without sheathing.

How to attach and install - installation

We mount the sheathing to the surface of the batten

You need to start work from the corner. Laying must be done tightly. The thin part faces towards the corner. The fastening is carried out on the surface of the rail.

You can successfully install MDF panels on the wall with your own hands if you prepare slats with a cross-section of 20 by 40 mm. They will need to be secured using self-tapping screws and a screwdriver.

The location of the slats must be perpendicular to the direction of the panels that will be mounted. In order to mount the sheathing elements, we adhere to an interval of 40 - 50 cm.

Using the mounting level, we constantly check the evenness of the installed slats. If the wall surface turns out to be uneven, it is necessary to level the sheathing using such building materials, How:

• plywood;
• beam;
• assembly adhesive.

Used to secure the surface long screws or dowel - nails. This will depend on what materials the walls are made of. Also constantly monitor this process by measuring the evenness of the surface using a level.

The bottom of the slatted sheathing should be located taking into account a distance of 3 - 5 cm from the floor. This will allow you to successfully secure the floor plinth in the future.

At the top, the sheathing is mounted at ceiling level.

• the sheathing is attached in different positions:
• in the corners;
• along the window opening.

If work is carried out where there is a high level of humidity, it is advisable to install elements plastic sheathing or made of metal. You can watch a video on how to install MDF panels on a wall surface. If you use the “groove-to-groove” fastening method, over time you can easily disassemble the structure.

Installation and installation technology of the first panel

For execution installation work By MDF installation panels on the walls must be started from the corner:

• attach the first panel;
• We check the level;
• We fix the panel with self-tapping screws to the slats along the entire height.

A thematic video from the Internet will tell you how to attach MDF to the wall.

How to attach to the sheathing

In order to fasten MDF panels to the wall sheathing, clamps are used - special type staples.

The clamps are pushed into the cavity of the panel groove and secured using a construction stapler.

It is best to use nails. Constant care must be taken not to damage the edges of the panel.

To avoid this, use pliers. We install the remaining panels. The ridge of the panel that will be next in the row is inserted into the grooves of the panel that is already installed.

A video about installing MDF panels on a wall can be viewed before starting work. Next you need to attach it to the sheathing and carry out the same work in the required quantity.

The last panel next to the wall may not be the right size. If necessary, you can cut MDF panels with a jigsaw or wood saw.

Cutting it out will not be difficult, the main thing is to correctly measure the part that will be cut. This way they will be the right length. By following the instructions in the instructions on how to attach MDF to a wall, you can do such work yourself. We install the fittings.

In order for the MDF wall mount interior to look like a finished product, it is necessary to install MDF fittings. You can close the joints using a folding corner.

Apply glue to the surface inside and press firmly to corner panels. After execution finishing works With the use of MDF panels, the appearance of the walls will be significantly transformed.

How to secure without wooden guides

You can attach mdfc panels to the wall without lathing. In this case, the lower part of the panel must be clamped between the wall and the plywood. Top part must be inserted into the start profile. It is screwed to the top panel.

To be able to further secure the structure, you need to make another hole in the middle to secure the panel. MDF fastening panels to the wall without slats is done using wooden choppers and self-tapping screws with caps.

The panel will fit perfectly tightly to the wall, and you will be able to save at least 4 cm of space if you install the MDF panel on walls without lathing.

For additional fixation of the panel to the wall, professional mounting foam is used. The foam will not be destroyed under the panel, since it does not get there. sun rays. Spray the top and bottom of the surfaces with foam. The fastening of MDF boards to the wall must be reliable.

The panel is glued, and one additional screw is added in the middle. about how to glue MDF to the wall. This will be quite enough. The strength and durability of the entire structure depends on how you can attach the MDF to the wall.

How to attach a plinth - installation methods

MDF plinth can be attached to the wall in several ways:

• on self-tapping screws;

• mark the place of cutting;
• make a cut;
• apply glue;
• press against the wall with force;
• install the corner element.

Most often, the baseboard in an apartment matches the platband, this gives the structure an unesthetic appearance. To prevent sharp corners from spoiling the appearance of the baseboard, you need to file the corners by turning them inward.

Do-it-yourself MDF mounting on walls in the kitchen

Can be installed attractively with wall mount. Panels with photo printing are perfect.

Compared to aprons made from other materials, it can be installed directly in the kitchen, adjusting all technological dimensions during the installation process.

The panel needs to be marked and, if necessary, holes cut for electrical outlets. On a flat surface panel MDF is glued using liquid nails.

Gives the room beautiful view. Installation of the apron and additional elements is carried out quickly and with minimal construction waste.

conclusions

Practical and environmentally friendly MDF panels are widely in demand in modern construction. They are made by pressing wood dust in a vacuum. In this case, the color of natural wood of various shades is achieved.

If you learn in detail how to mount MDF panels on a wall, You can radically change the appearance of any room in the house. Installation of MDF panels on walls, the price of which will depend on the quality of the selected materials and volumes necessary work, more profitable than working with natural materials.

You can learn how to install MDF panels on the wall from the video. This material is so easy to use that work can be done quickly and efficiently.

Covering walls with MDF panels is an affordable and simple way to decorate residential premises.

The finishing material has a decent attractive appearance, has excellent heat and sound insulation properties, and installing MDF panels with your own hands is not very difficult.

Interior decoration of walls with MDF panels is carried out in two main methods: on the lathing and directly on the wall surface. Preference for one or another finishing option is based on the condition of the walls in the room and its operating conditions.

Frame method

The essence of the method is to attach finishing MDF boards to a pre-constructed sheathing. It is used in several cases:

• the wall surface is uneven and there is no way to eliminate the defect;
• the room needs heat or sound insulation;
• there is a need to hide engineering Communication– wiring, for example, located on walls.

Finishing materials

Using the frame method, it is possible to install MDF panels on a wall of any form factor - slats, wall panels and decorative sheets. The appearance of the slab, the thickness of the panel, and the quality are determined not by the installation method, but by the functionality of the room.

1. Form factor.

The most commonly used material is rack material, since, thanks to the tongue-and-groove joint, its installation is simple and does not take much time.

Cladding with tiles and sheet panels more difficult, since it is associated with the need to comply with a certain pattern.

1. Thickness.

The slabs are produced with a thickness of 6 mm for slats, and from 3 mm for sheet products. For finishing the walls of rooms with severe operating conditions, it is recommended to choose MDF panels of maximum thickness.

1. Moisture resistance.

Moisture-resistant MDF panels are used for finishing bathrooms, toilets and kitchens.

Tools and Supplies

• MDF boards - slatted, panel, sheet.
• Universal corner made of fiberboard - used when decorating corners.
• – if thermal insulation work is being carried out.
• Hammer, jigsaw, knife.
• Square and usually nylon thread.
• "Liquid nails" or other wood glue.
• Wood screws - from 40 to 80 mm, plastic dowels or plugs - for attaching the sheathing.
• Nails, clamps with a tongue of the required height, glue - depending on the chosen method of installing the panel.

Preparatory stage

1. Since during the installation of MDF panels on metal carcass or the wooden sheathing is not made, then preparing it comes down to cleaning it from dust and dirt. However, if there are large cracks on the wall, they should be repaired.
2. The wiring is retracted into corrugated pipes.
3. If there is a general high level of humidity in the apartment, it is recommended to treat the surface with an antiseptic primer.

The coefficient of thermal expansion of MDF products is low, but moisture resistance is low, so the material should be kept indoors for 2-3 days in order to equalize the humidity of the board and the air.

With a small sheet thickness - 3-6 mm, this stage can be neglected; with a large sheet - 16-20 mm, exposure is necessary.

Manufacturing and installation of sheathing

The frame is made from wooden blocks with a cross-section of 20×40 mm, or a galvanized profile. Both solutions have their advantages

Wooden sheathing is much easier to install, does not require a large amount of hardware, and is characterized by the ability to absorb and release moisture at a level close to MDF boards.

In this case, the material requires additional processing antiseptic agents and does not exclude the possibility of destruction under the influence of moisture.

The metal frame is highly durable and resistant to moisture.

MDF installation panels on a metal profile provides rigid fastening, which prevents the panels from elongating. In rooms with noticeable changes in temperature and humidity, for example on a loggia, this leads to warping of the finish.

Since, with the exception of special moisture-resistant ones, they are also not resistant to moisture, you should not build a frame more durable than the sheathing itself.

Installation of lathing for MDF panels: detailed instructions

Slat slats can be positioned horizontally, vertically or diagonally. Square panels can be formed into a pattern. In any case, the installation directions of the sheathing strip and the MDF panel must be perpendicular to each other.

The diagonal method of laying panels is more material-intensive.

Most often used vertical installation finishing, as it ensures a minimum of waste.

1. The most convex place on the wall surface is determined - its height is the control point.

The frame rail must pass through the top of the convexity.

1. The recommended pitch is 40–60 cm. If the sheet size is large, the pitch can be increased.

The possibility of increasing is checked as follows: if the panel bends slightly when pressed by hand between the slats, then the change is permissible.

1. The wall is marked with a pencil.

In this case, it is advisable to place the bottom strip as close to the floor as possible: the baseboard is attached to it.

1. The first to install the rail is the most convex place.

The block is placed on the marked line, and a hole is drilled in the wall through the plank using a hammer drill. The depth of the hole is calculated so that the self-tapping screw is in main wall no less than 30–40 mm. The fastening pitch is at least 60 cm.

1. First of all, the rail is fixed at the top of the convexity - close to the wall, and then at the opposite end, previously leveled.
2. To check the plane of the block, a thread is pulled from one end to the other end of the wall and fixed on self-tapping screws at a level; a match is placed between the head and the thread.

Correction of the rack fastening is carried out using wedges, the thickness of which is determined by the deviation of the fastening depth compared to the control point.

1. Blanks for wedges are cut from a lath and trimmed with a knife as work progresses.

It is allowed to use pieces of plywood.

1. The second rail, usually lower, is installed in the same way: the ends are fixed level, and the rest of the fastening is adjusted along the thread.
2. The following frame elements are mounted as follows: the rule is applied to the fixed slats, and the next bar is aligned in the plane with the first two.

It is prohibited to attach any objects to the MDF panel. However, it is quite possible to hang a mirror in the hallway if the installation wall MDF panels are carried out on the frame.

Wall cladding with MDF panels

Sheathing begins after constructing the frame.

Mounting methods:

• Glue it.

The adhesive composition is applied to the panel in the areas of fixation to the sheathing. Suitable for thin slabs;

• Mechanical fastening with staples, nails or screws.

Provides reliable fixation, but does not compensate for thermal expansion. The method is recommended for rooms with stable temperature and humidity;

• Fastening with clamps.

The clip is placed on the edge of the panel and secured to the sheathing with nails. This is the most recommended option.

Installation sequence

1. Slat slats and universal corners are cut to length using a jigsaw or hacksaw. The edges are sanded.
2. Installation can be started from any corner of the room.

1. The first lamella is fixed in such a way that the edge with the ridge is directed towards the corner, and the gap between the wall and the sheathing board is 2-3 mm.

On the ridge side, the lamella is fixed with self-tapping screws to the slats, and on the groove side, a clamp is put on the edge and secured. When joining, the fastener is hidden by the ridge of the next element.

The next panels are inserted with a comb into the groove of the previous one and secured with clamps.

1. The last panel usually needs adjustment.

The slab is tried on, the required width is determined, and the excess fragment is cut off. Then the element is inserted and also secured in the corner with self-tapping screws.

1. The corners and top edge are finished with a universal corner.

Design of sockets and switches

When decorating walls with MDF panels in such areas, you must:

• try on the panel and mark the location of the outlet;
• cut a hole of the appropriate diameter;
• fasten two parallel blocks to the wall so that the future socket can be installed on them;
• fix the MDF board to the sheathing.

Frameless method: do-it-yourself cladding

The method is implemented when the walls of the room have a flat surface, or if one of the tasks of the repair is their careful alignment. Any MDF products can be used, but more often this method

Preparation

Before proceeding with the installation of MDF panels with glue, the surface is cleaned and primed. The most commonly used primer is with an antiseptic effect.

The slatted lamellas are cut to the required height, the corner is also cut off, and the edges are processed with sandpaper. Square panels are adjusted after fitting.

Adhesives used

The adhesive composition must satisfy two requirements:

• After drying, maintain some plasticity to absorb the thermal expansion of the material.
• Have a dense structure, which would allow the glue to be applied in both a thin and thick layer. This property makes it possible to properly attach the panel even in cases where the wall surface is curved.

Most often, “Liquid nails” and “Moment installation” are used, but there may be other options - “MitreFix”, “Moment Crystal”.

Installation of cladding: sequence of actions

1. It is recommended to start covering from the corner towards the window opening.
2. Horizontal and vertical markings are made on the wall according to the size of the panels.
3. Glue is applied to the back of the slab in zigzag strips.
4. The panel easily presses against the wall and is immediately removed.

After 2–5 minutes it is fixed tightly. This way a stronger connection is achieved. The first lamella must be checked with a vertical level.

1. The slabs are laid end-to-end or overlapping.
2. In areas where it is planned to install sockets and switches, holes are pre-made in the panel.
3. The corners and upper edge are sealed with a universal corner, the lower edge with a plinth.

Finishing nuances: processing joints and corners

A universal corner is used for finishing corners. It consists of two plates made of chipboard and connected on the front side with a film.

The strips can bend both inward and outward, which allows the element to be used to decorate any corners.

1. The corner is cut to the required length. Docking, if the top edge is being decorated, is done at an angle of 45 degrees.
2. It is recommended to apply glue to the glue in two stages: light pressing so that the composition is distributed both over the cladding and on the surface of the corner, and then firmly with pressure.
3. Remains of glue, if they do appear, are cut off with a painting knife after complete hardening. They are difficult to remove with cleaning agent or solvent.

Joints are finished in exactly the same way, if such a need arises. However, in this case it is necessary to carefully select the element by color.

Finishing MDF boards does not apply to work high level complexity and requires not so much experience as careful execution.

From an aesthetic point of view, it is not recommended to decorate both the ceiling and the walls of the room with slabs at the same time. Styles that involve such a solution are not implemented in city apartments. But for a balcony or loggia this is a completely acceptable option.

Using MDF panels is the easiest way to decorate the walls of a room, especially if you need an additional layer of thermal insulation. At the same time, it is quite possible to install MDF panels with your own hands in a very short period of time.

To install the panels you will need:

• tape measure and pencil - with their help you will mark the places where the sheathing bars are secured and the required length of the panels;
• metal corner and level - to check the evenness of the corners, horizontal and vertical of the mounted elements;
• jigsaw - for cutting panels to the desired length or width;
• construction stapler or nails with a hammer - for securing the panels to the sheathing;
• drill and self-tapping screws (dowel-nails) - for attaching the sheathing bars to the wall;
• screwdriver or screwdriver.

Surface preparation

One of the main advantages of MDF panels is that there is no need to completely level the surface to which you are going to attach them. In this case, it does not matter at all whether the wall was pre-painted or not, and what material it is made of (brick, concrete, blocks, wood). It is enough to simply cover the plastered or wooden surface(2 times) with a primer (or a special composition for protecting wood), and then either immediately fix the sheathing for mounting MDF panels, or first fix a layer of thin thermal insulation (such as foil insulation) to the wall (using “liquid nails” glue).

Ceiling

If desired, MDF panels can be easily mounted on the ceiling. In this case, it is better to follow the rule that MDF panels should be positioned perpendicular to the wall with the window. The principle of installing MDF panels on the ceiling and walls is the same, with one small exception: to cover the ceiling, you will most likely need an assistant who will support the panel and supply tools.

Installation technology

The process of installing MDF panels with your own hands means that you will attach them to a wooden sheathing, which is bars of any cross-section fixed at a certain pitch (in the direction perpendicular to the direction of installation of the panels). In this case, the size of the block (its width and thickness) does not have of great importance(that is, any of the same thickness will do).

If you are going to lay a layer of insulation under the MDF panels ( mineral wool or glass wool), the thickness of the block must correspond to the thickness of the thermal insulation layer.

After preparing the bars for the sheathing, do-it-yourself installation of MDF panels will be done as follows:

• Select the direction of installation of MDF panels.
• Fasten the sheathing in a direction perpendicular to the panels being installed: bottom beam at a distance of 3 to 5 centimeters from the floor, the top beam is 2-3 cm from the ceiling, between them fasten the bars with self-tapping screws in increments of no more than 45-50 centimeters.
• Check the verticality of the resulting surface. If necessary, place pieces of plywood, fiberboard or laminate under the sheathing bars.

• Secure vertical sheathing bars around (along the perimeter) of windows and doors, as well as in the corners.
• If you decide to mount the panels vertically, then you should start installing MDF panels with your own hands from the corner, moving from right to left. Attach the first panel (from the edge with the ridge) to the bars along the entire height using self-tapping screws, which should be as close as possible to the corner of the room.
• Secure the second edge of the panel using staple clamps specially designed for working with MDF, which can be attached to the block with a construction stapler or small nails.
• We install all other panels on the wall in the same way, inserting the ridge into the groove.
• The last (on each wall) MDF panel must be trimmed to the right size, and then insert it into the groove of the previous one, securing the cut side with screws to the bars.

• Having finished installing MDF panels with your own hands, do not forget to cover the corners of the room with special MDF corners, which are simply glued on top of the panel. The screws holding the outer panels should be hidden under these corners.
• Similarly, glue MDF corners to the edges of the panels near windows and doors.

Advantages and disadvantages of MDF panels

The undoubted advantages of MDF panels include not only ease of installation (they can be mounted both vertically and horizontally), but also a beautiful appearance, which, thanks to a wide variety of colors, allows you to choose panels for almost any interior. In addition, MDF panels are easy to care for, since they do not require special cleaning (just wipe with a slightly damp cloth). And, of course, MDF panels are relatively cheap finishing materials.

But MDF panels also have disadvantages:

• Firstly, walls made of such panels, due to the fact that they are attached to the sheathing, remain hollow.

If you decide to hang something on such a wall, you will have to use special long dowel nails. In addition, MDF panels do not hold up well to impacts from sharp objects (although damaged trim can be disassembled and the panel replaced).

• Secondly, wooden sheathing under the panels, MDF is a flammable material (like the panels themselves), so they cannot be used for finishing escape routes - corridors, staircases and so on. (this rule does not apply to individual residential houses and apartments).
• Thirdly, MDF panels do not form a continuous, smooth, flat surface (that is, you will always see the recesses at the places where they join), which imposes certain restrictions on the designed design of the room using them.
• Fourthly, if you make the sheathing pitch larger than recommended (45-50 cm), then the panels may begin to “play” under external influence from the side of the room (for example, if you lean on them).

However, even despite the shortcomings, MDF panels still create competition for drywall, the installation of sheets of which requires much more skills and people (at least two), while working with MDF panels can be done alone.

How to mount MDF panels to the wall, and on what basis, the decision must be made taking into account the characteristics of the wall geometry, the size of the room, the presence of communications and constant heating. Despite their enormous popularity, MDF wall boards are quite picky about operating conditions, so you should not fasten them with the first method that comes to hand, so as not to re-lay the finish a second time.

Dimensions of MDF panels

Often, consultants of trading companies present MDF boards as a lightweight version of particleboard panels, especially if you decipher English abbreviation. Accordingly, it is recommended to fasten them in the same way as in the case of using chipboard. In fact, MDF panels in structure and production method differ significantly from particle board, which allows you to fasten the material at lower costs and at higher speeds.

There are only three main differences:

• Thin MDF boards are made from recycled cellulose fiber, which contains virtually no polysugars - a staple food for bacteria, fungus and rodents. Chipboard uses ordinary chips filled with phenol-formaldehyde resin, so they are secured with special tongues;
• The boards are made by pressing wood fiber mass with the addition of hydrogen peroxide. At a temperature of 250 o C, lignin and part of the cellulose are welded by the remains of caramelized polysaccharides into a dense fiber mass. In thick slabs, the MDF core is additionally impregnated polymer resin, which makes it possible to fasten without the risk of material delamination;
• The bending strength of the panel is only slightly inferior to plywood with greater ductility and resistance to moisture. Most brands of MDF can be mounted on walls even in rooms with low levels of ventilation.

The difference, at first glance, is insignificant, but it is the strength and elasticity of the cellulose fiber base of the MDF panel that makes it possible to fasten the cladding slabs using end locks.

Even with a strong temperature difference, the MDF panel shows a level of expansion that is significantly less than that of plastic or conventional wooden lining, so the material can be fixed with smaller gaps, which is especially important for slabs of medium and large thickness.

What sizes are most popular?

Three size groups are used for wall cladding:

• Thin slabs, size group 5-9 mm thick, width 153, 198, 200,325 and 2070 mm;
• Medium MDF panels, thickness 10-18 mm, width 2070 mm;
• Oversized slabs, thickness 19-38 mm, width 2070 mm.

There are no restrictions on external dimensions, and the maximum thickness of the slabs is limited by the pressing capabilities of up to 40 mm. Double-layer MDF panels with a maximum thickness of up to 60 mm are also produced, used for the manufacture of reusable formwork and roofing lining. But the quality outer surface The number of such slabs is quite low, so they are not used for wall decoration.

Installation of MDF panels

Pressed cellulose fibers retain heat and absorb noise much better than plastic or wood. In addition, the MDF panel has a certain anisotropy of properties; it can be cut and processed in almost any order. Attaching the panels is easy and even a novice tiler can do it.

For home purposes, panels can be mounted in three ways:

• Lay the slabs on the glue;
• Mount the cladding on a wooden or metal frame;
• Installation of MDF panels using the hanging method.

The latter case is used as an exceptional way of cladding walls in a house made of timber or rounded logs. It is necessary to mount MDF boards on a ceiling-mounted suspension profile with a small gap between the floor and the lower edge of the board. The cladding ends up suspended on the profile, and as the walls shrink, the MDF sags along with the timber material.

It is clear that for wooden house It would be more preferable to use narrow slabs, 190-200 mm wide, while it is better to mount MDF in the vertical direction. If it is not known exactly about the planned amount of wall shrinkage, then it is best to attach the decorative trim with a gap increased by 2-3 cm. Firstly, this ensures that if excessive shrinkage occurs, the floor will not tear the slabs off the walls, and secondly, the gaps will ensure a normal level of ventilation and ventilation of the space between the panels and the wall.

Installation on a metal frame

Installing panels on a supporting frame made of galvanized profile is recognized by experts as the most rational and reliable way of fastening any cellulose-fiber materials. Even heavy slabs with a density of up to 1.5-1.8 g/cm 3 can be attached to a metal frame without any problems. The metal will not suffer from condensation or soaking of the walls as a result of burst pipes, water leaks in the apartment on the floor above or a break in the roof.

Frame assembly begins with installation starting profile and side strips. MDF panels are light in weight, so it is enough to install a number of vertical profiles No. 50 in increments of 40-50 cm. Using a galvanized U-profile makes it possible to attach MDF to the walls of a room approximately two to three times faster than any other method.

Two or three drops of silicone applied to the profile will even out the load on the wall and will prevent the cladding from flapping in a strong wind if there is a ventilation gap behind the decorative MDF lamellas.

Installation on a wooden frame

The easiest way is to mount MDF panels on a wooden frame. There are two options for wall cladding using cellulose fiber panels. It all depends on the size of the room and the condition of the walls.

If a slight reduction in space due to the sheathing is not critical, a frame made of wooden slats is sewn onto the walls using metal hanger holders. For small and small rooms, most often it is necessary to partially cut and knock down a layer of plaster in order to level the surface along a vertical plumb line and make it as smooth as possible.

In any case, the starting strip is initially laid on the floor and under the ceiling. Using a long building level, the installation points of the hangers are marked on the wall and the minimum required overhang of the side lobes of the fasteners is determined.

If you plan to install horizontal MDF slats, the supporting strips are mounted vertically. To install full-size panels with a width of more than 200 mm, the walls are sewn in both directions. Each wooden plank of the sheathing is aligned along the starting guides and fixed with suspension petals using self-tapping screws and a screwdriver.

For relatively level and dry brick, concrete or block walls, the sheathing can be attached directly to the wall using dowels. In this case, more work is added, since each plank before fastening has to be adjusted for a long time using shim washers in order to maintain a single vertical plane. But you can save 3-4 cm of internal space, which can be very useful, for example, when decorating the walls of a small bathroom or corridor.

Glue installation

Using lathing or a load-bearing frame always eats up an additional 3-7 cm of space on each wall. The use of a frame system is considered good decision, but it is not at all necessary to fence a frame jungle if the walls of the room for future cladding with MDF panels turn out to be smooth, without serious defects and deviations from the vertical.

In this case, it is enough to clean the walls, prime them with acrylic primer and apply a thin layer of insulating putty. The lime sublayer will help to further level the walls and improve the adherence of MDF boards to the supporting surface.

Laying panels on walls using glue is carried out in two options:

• Each MDF is glued to the wall with one lamella, from ceiling to floor, with fixation along the end edge using self-tapping screws and plastic plugs;
• The material is laid on the wall horizontal stripes from corner to corner after assembling and gluing in corner and edge parts.

If the slats are glued directly to the wall, then the end joints are not glued or treated with sealing materials. Most often, fairly large panels, 40-60 cm wide, are laid on walls using glue. This method is more advantageous from a technological point of view, since the load from the considerable weight of the MDF panel is distributed not over several clamps or staples, but over the entire surface of the slab and walls. What does this give? Greater reliability, if the top row of MDF lamellas breaks, the middle and bottom rows will hold the entire structure.

Before attaching the MDF panels to the wall, the back side is covered with small portions of glue. These can be dots, spirals, short stripes. The main thing is that the adhesive material is evenly distributed over the wall surface.

As glue, it is best to use automotive sealant, polyurethane adhesives and homemade adhesives based on a mixture of acetone and polystyrene foam. Acrylic and polyvinyl acetate adhesives hold MDF panels rather weakly.

For your information! The MDF sticker on the sealant makes it possible to trim and remove the panel from the wall if necessary without damaging the surface. Stiffer alkyd, polystyrene and acrylic adhesives can tear off part of the back surface.

Fastening MDF panels to the wall

The process of installing cellulose fiber panels is relatively simple and easy to understand, even for a beginner. If used horizontal method installation, then the first one is installed the bottom panel or a lamella directly resting on the starting strip of the frame. It needs to be laid on glue, aligned construction level and secure with a stapler or self-tapping screw.

Before laying the next panel on the wall, it is necessary to install the corner or edge cladding elements, fix them on the wall, and only then proceed with laying the next parts of MDF.

How to fasten MDF panels to a bar or profile is selected individually in each specific case, based on the fastening conditions and the size of the material. Relatively thin, 6-9 mm lamellas are snapped into place with tongue-and-groove locks, after which the free end is sewn to the beam with staples and self-tapping screws. If it is assumed that it is possible to periodically remove the MDF cladding from the wall to inspect communications or wiring laid behind the decorative trim, then the panels are installed with clamps.

Thick slabs are mounted directly on the walls using glue and dowels, sealing the joints with acrylic putty and then gluing wallpaper or PVC film.

A difficult option on how to install MDF on walls with insulation

MDF boards are much simpler and more convenient to handle than heavy plasterboard, plywood or plastic, while the strength of the panels is enough to build two or even three-layer cladding options from a fiber composite with insulation as an intermediate layer.

For example, cold external walls made of profiles, siding or concrete blocks are hemmed from the inside with HDF class MDF boards, with a density of 800-1800 kg/m3. The thickness of the slabs is 25-40 mm. The laid panels are stitched at the joints with oblique screws and staples, and the seam itself is rubbed with polymer mastic.

The material is treated with impregnation, which ensures good vapor transmission with high resistance to surface condensation. The slabs are fastened to the external walls “cold” - using steel dowels and carpentry screws. On the inside of the slab sheathing, wooden slats or strips cut from the slabs are sewn.

A steam membrane is stretched over the laid thermal insulation and hammered in with horizontal slats with a cross-section of 20x20 mm. The last step is to sew the lungs onto the slatted sheathing. decorative panels MDF class LDF with wood texture, natural stone or veneered.

Due to the low density of LDF, 200-600 kg/m 3, MDF panels perfectly transmit steam, which is removed through the ventilation gap and the ceiling ventilation seam. In this way the walls are sheathed in summer kitchens, balconies, verandas, any premises with frame-type walls.

Features of finishing with MDF panels

Most professional finishers prefer to work with MDF, since there is no dust and dirt, as is the case with drywall, installation is faster, and there are much fewer problems.

Assembly and installation of MDF on walls is in many ways similar to laying laminate floors, the only difference being that there are more options for choosing patterns decorative design premises and a much more complex arrangement of corner and slope sectors of the walls.

Slopes

Scheme of arrangement of door or window slopes no different from plasterboard options. If the slats were laid vertically on the walls, then to design a window or doorway it is enough to cut a panel of the required height and width and stick it on the slope plane polyurethane foam or sealant.

If the walls in the room are protected by horizontal panels, then the slopes will have to be assembled from sections with self-tapping screws and plastic plugs.

Corners and crevices

Between the laid additional elements and the main part of the cladding, cracks and gaps always form. They have to be eliminated with the help of special decorative corner trims and decorative skirting boards.

All auxiliary decor is glued to “Titanium” or “Mounting Moment for MDF”, a small amount of glue is applied to the edge along the gap, after which a corner strip is installed at the joint. To prevent the decor from coming off, the corner is temporarily fixed with tape.

Sockets and switches

Every room has at least a couple of outlets and one switch. In order not to dismantle them during the installation of MDF, proceed as follows: measure the coordinates of the location of the socket on the wall, after which a hole of the appropriate shape and size is cut out with a ring drill or jigsaw. When installing an MDF panel, the size and position of the hole is specified and trimmed with a sharp knife.

All that remains is to install the panel, secure it to the wall, and close the remaining gap with a decorative frame.

Conclusion

The details of the process, how to attach MDF panels to the wall, must be thought out and planned in advance, before work begins. decorative finishing premises. The process itself is not particularly difficult, but in any room there are many problem areas where you almost have to invent the fastening method on your own. In this case, it is better to draw the details and method of fixation on the diagram, so that you do not have to rack your brains and waste time during the work process.
