How to plaster brick walls with your own hands. Technology for plastering brick walls. Technology for plastering brick surfaces

Finishing the room begins with leveling the walls. To do this, use the dry method (using drywall), wet (plaster mixture), or a combination ( piece materials). But the most effective and reliable is wet leveling. Although it is the most labor-intensive, it allows you to level out all the unevenness and create a durable coating.

In this article we will look at how to choose plaster for brick walls, prepare the surface and perform rough finishing.

How to plaster brick walls correctly

Wet rough finishing is intended to eliminate pronounced irregularities and improve the performance properties of partitions and ceilings. The technology for plastering a brick wall does not depend on the type finishing material and includes a number of works that must be performed in a certain sequence.

Important: Rough plaster of a brick wall is carried out on completely dry brickwork, otherwise the surface will shrink, forming cracks and chips.

Preparing the base

Regardless of whether plastering is performed brickwork inside or outside the building, you must first clean the surface and make cuts on it - this will improve the adhesion of the material to the walls.

Preparing the base

After cleaning, the surface should be treated with a primer, beacons should be placed, which will allow achieving the same thickness of plaster over the entire area. Guides can be made of metal profiles or beams.

For your information: Beacons must be set strictly at level, without blockages or slopes.

Example of beacon installation

The inclination of the beacons is adjusted by level. The verticality of their installation can be checked by applying the rule to several beacons at once.

Checking the evenness of the installation of beacons

Technology for plastering brick surfaces

The solution is applied in three layers. The first is spraying - the mixture is sprayed in small portions onto the brickwork, completely covering its entire surface.

Advice: To further strengthen the mortar on the wall and prevent its deformation, the rough finishing will be done using a grid. It is attached overlapping the first layer of plaster before installing the beacons.

Spraying red brick walls

Next comes the application of the base layer. It is leveled and rubbed at the end. Last layer- covering, made of pure cement. It is rubbed in with a grater, the beacons are removed and all grooves are sealed. The thickness of the plaster layer on the brick should be at least 10 mm.

The covering layer is designed to create a protective crust on the surface

The technology for plastering a brick façade is slightly different from the interior rough finishing. In addition to the primer composition, you will need to joint the joints, and sometimes use reinforcement, which is needed for better adhesion of the smooth brick surface to the finish.

On a note: plaster for external work on bricks must have increased weather resistance.

Selection of rough finishing mixture

Which plaster is best for brick walls? Wet rough finishing of surfaces can be done with the following mixtures:

• limestone;
• cement-sand;
• plaster.

If the building is made of brick, the best option Brick walls will be plastered with cement-sand mortar. It's simple and economical way implementation of rough finishing.

The advantage of the sand-cement mixture is that it allows you to make a leveling layer with a total thickness of up to 7 cm

Sand-lime brick white, consisting of lime, cement-lime plaster is more suitable. The solution is applied in a layer of at least 20 mm, since this construction material has low resistance to moisture.

Although finishing brick is considered a rough job, it is a very important element under repair. After all, it will depend on it how even and smooth the walls are, and how the wallpaper or other cladding you choose will look. Therefore, you should take this stage of work very seriously and choose good materials.

In order to understand what composition to choose for plastering walls, you need to consider each of them separately.

Cement-sand mixture (CPS)

One of the most common and affordable types. You can prepare it yourself, with sand in a ratio of 1:3 with a small amount of water. However, we advise you to purchase such a mixture already in stores, since it is guaranteed to have a good composition. This solution is quite easy to use, but the downside is that it hardens for about four weeks.

Limestone

You can also make it yourself. To do this, place slaked lime in a basin or bucket and add sand to it in a ratio of 1:5, then pour in as much water as necessary to obtain a homogeneous mass. This mixture is perfect in rooms where there is high humidity.

Gypsum plaster

Since this material is not suitable for damp rooms, as well as where internal floors are subject to shock, vibration and any mechanical influences. However, there are also advantages - this composition hardens within 5-7 days.

After we have considered three options plaster finishes, you can make a choice for yourself which is better to plaster inside the house. However, we advise you to stick with CFRP, since both gypsum and lime are significantly inferior in strength.

Preparing the walls

Before talking about preparation for plastering brick walls, it is worth noting that the masonry should not be completely fresh. She needs to be given time to settle. Otherwise, even the most durable plaster will quickly become cracked and fly off. We offer you to study the entire process step by step.

Cleaning

First of all, it is necessary to clean the masonry from dirt and dust. If this is not the first finish, then dismantle the old coating and clean the space between the bricks with a brush with metal bristles.

After you clean the surface, it needs to be treated with an antiseptic for the outside.

Primer

This stage is necessary in order, firstly, to ensure strong adhesion to subsequent layers. And, secondly, it prevents moisture from penetrating inside the bricks. It should be taken into account that all building materials of this type have different porosity. For dense bricks, a composition with increased adhesion properties is suitable. For bricks medium density Can . If it is porous, then it is better to buy the composition at mineral based and apply it in two layers.

The surface should be primed with a layer 0.2 millimeters thick.

The porosity of a brick can be determined independently. To do this you need to drop water on it. If it was absorbed almost immediately, then the porosity is large; if it dried for 5-20 minutes, it is average; if drying took even longer, then the building material is very dense.

Reinforcement

It will be better if you purchase a plastic product as it is not susceptible to corrosion. However, if you have a metal mesh, then pre-treat it with a special varnish. Otherwise, rust may appear in the future in the form of yellowish, unsightly spots.

Installation of beacons

First you need to prepare a solution on which the beacons will be attached. If you have, then it is made of plaster accordingly. However, there is one subtlety here - to make work easier, this mixture should be slightly more liquid than the main one.

As for the installation of beacons, they themselves are from 2.5 to 3 meters long and 6 and 10 millimeters thick. You adjust their height and quantity based on the size of the room. We recommend maintaining a distance of no more than 1.5 meters between beacons.

Next, “cakes” from the previously prepared solution are applied along one vertical line, after which metallic profile pressed into them and leveled using a level. This is how all the beacons that you are going to plaster are made.

First, install the two extreme ones. If the surface is large and you need a lot of profiles, then stretch a fishing line between them, which will serve as a guide for the intermediate slats.

Instructions on how to plaster walls with cement mortar

After all preparatory work You can proceed to the most important thing. You will need the following tools:

• Master OK
• level
• plaster ladle
• rule
• bucket or basin for mixing

Mix as directed by the manufacturer in the instructions. Then we wet the brick. This is very important, because if this step is skipped, it will absorb all the moisture from the prepared coating. Because of this, it will harden quickly and make further finishing difficult.

After moistening the surface, use a ladle to begin pouring the solution onto the wall. Let the mixture dry for a couple of hours, then repeat the process. As soon as you notice that the material has begun to extend beyond the beacons, remove the excess using the rule. If after this bald patches have formed on the surface, then throw the material into this place and re-level it. This way we achieve a uniform coating over the entire surface.

After the final coating, profiles with a thickness of 6 millimeters can be left inside, but large ones must be pulled out from the inside, otherwise they, like the reinforcing mesh, may become covered with rust, which will subsequently appear on the inside facing material. Fill the voids from them with a solution and level with a spatula.

After watching the video, you can reinforce your idea of ​​how to properly plaster a brick wall.

This step applies to both materials. Grouting is done on fresh plaster using a plastic or wooden trowel in a circular motion. At this stage, the surface becomes perfectly flat and ready for wallpapering. If you plastered the walls for tiling, then you can completely skip this step.

Decorative plaster

This material allows you to give the surface. It contains synthetic resin, thanks to which the composition can be considered a complete and strong cladding.

Types of decorative plaster:

• limestone-sand;
• stone;
• terrazite.

This plaster is quite unpretentious in work. Before applying the very first thin layer, install the reinforcing mesh. let it dry, and then show your imagination.

It can be casually applied with a spatula, thus forming large strokes, or with a simple broom you can create roughness on the unhardened composition. You can also use a stamp that will create identical patterns. After drying, you can paint it or leave the original texture.

Sooner or later, almost all homeowners face repair work. Most often it is necessary to finish brick walls. The best way today to hide all uneven surfaces of the walls is plaster.

There are several methods of plastering:

• using rules. This option excludes the use of beacons. The method is suitable for walls with a slight curvature;
• in advance installed beacons. It is advisable to use for walls with large unevenness.

• finishing Using this plaster, the surface is leveled and prepared for finishing (painting, wallpapering, etc.);
• decorative. This type of plaster is used for decorative design certain parts of the wall and is divided depending on the application technology into: structural, textured and mineral.

Preparation of the solution

To plaster a wall, you need to prepare a proper solution. For brick surfaces you can use the following types solutions:

• cement. The materials for its manufacture are sand and cement. It is allowed to use this type of solution in rooms with high humidity;
• lime. This type can be used for plastering brick walls both inside and outside;
• gypsum-lime. The solution can be applied to inner part brick walls. Gypsum – increases the strength of the plastered surface.

Tools and materials

Basic tools and materials used for plastering walls:

• construction trowel (trowel);
• putty knife;
• rule;
• brush. Used to wet the surface;
• ruler or tape measure. Used to measure a layer of plaster;
• lighthouses;
• solution container;
• grater;
• falcon ( wooden plank with a handle. Used for applying mortar to the wall);
• metal brush;
• level;
• the components of the solution are cement, sand, gypsum, lime and water.

How to plaster a brick wall: step-by-step instructions

Preparatory work

If the masonry is fresh, it does not require labor-intensive preparatory work. It will be enough to install the guides or secure the mesh.

If we are talking about an old wall, then it will be necessary to carry out a number of measures to prepare it, namely:

1. Prepare the tools and necessary materials.
2. Thoroughly clean off old finishes, dust and dirt.
3. Clean the seams. An iron brush is suitable for these purposes.
4. Use putty to seal all cracks.
5. Cover with primer.
6. Before plastering, wet the wall with water. This can reduce the risk of cracks.
7. Installation of beacons

In order to achieve the most even surface of the walls, install the beacons correctly. With their help, you can control the thickness of the layer over the entire section of the wall.

Beacons can be:

• wooden;
• metal.

Rules for installing beacons:

1. Install the first beacon at a distance of 0.3 m from the corner.
2. The following beacons are installed on the wall every 100–150 cm.
3. Each beacon should be aligned vertically. For these purposes, use a level.
4. Lighthouses are attached to the wall using a concrete mixture.

You can start plastering the walls after 5 hours.

Splash

Spraying work should begin from the bottom of the wall, gradually rising to the ceiling. Work is carried out from left to right. To do this, a layer of mortar of liquid consistency with a high content of binding components, 4–5 mm thick, is applied to the brick wall. As a result, a strong adhesion to the uneven surface. Using a trowel, spread a small amount of this solution onto the wall. After three minutes, using the rule, it is necessary to level the layer of plaster. After the mixture has hardened, you can move on to the next stage.

Priming

Next step plastering works is the soil. For this stage it is necessary to prepare a thicker mixture. In one approach, a layer 10 mm thick is applied using a spatula. Next, the surface is leveled. To get more thick layer This operation should be performed in 2 passes.

Covering

Covering – The final stage in plastering work, which should result in a smooth
plane. The plastering process is as follows:

1. Prepare the solution. To do this, you need to carefully prepare all its components. The sand must be sifted.
2. Wet the wall with water.
3. Using a trowel, apply a thin layer of mortar to the wall.
4. Grout the surface.

If it is necessary to apply a layer of plaster mixture 50 mm thick, then the work should be carried out within two days. On the first day, apply the initial layer on which the notches are applied. You can make them using a spatula. Notches are necessary to ensure adhesion of the surface to the next layer. The next day, primer is applied to the walls and the final coat is applied.

1. In order to form the correct angles, you need to use a level and plumb line. At the final finishing stage, you should use corner rules(internal and external). In order for the surface to be as smooth as possible, the tool must be regularly moistened with water during operation.
2. After finishing plastering the surface, it is necessary to dismantle the beacons. If this is not done, then over time they will begin to rust and spoil the finish. Removal is carried out before the solution completely hardens. In place of the beacons, grooves are formed that must be covered with solution.
3. If the walls are made of ceramic bricks, then in order to plaster them, it is necessary to first carry out priming and mesh reinforcement.

If you need to plaster large area walls, then it is better to divide the entire surface into sections and carry out the work gradually.

Plastering brick walls is not difficult. The main thing is to take your time and strictly follow the technology of plastering work.

Plastering the surface is the most effective method combating uneven walls. Plastering of brick walls should be done experienced builders, but knowing certain nuances and following the technology, you can do the work yourself.

Today we will look at the purpose and functions of plaster for brick walls. Let's study the types of plaster mixtures used for brick walls. Let's find out what tool is needed for plastering. We will decide on the installation of reinforcing mesh, installation of beacons and their dismantling. Let's talk about the features of plastering indoors and external brick walls. Traditionally, at the end of the article, we will summarize.

The main task of plaster is to level work surface. In addition, the plaster mixture:

1. Protects walls from moisture.
2. Provides thermal insulation of the building.
3. Carries decorative functions.

Many novice builders often ask what is the best way to plaster brick walls.

Cement-based mixtures are often used. They work both indoors and outdoors. They are best used for plastering technical areas, bathrooms, and kitchens. It is necessary to understand that dry mixtures for plastering, after preparation, are placed on a previously prepared surface. How to plaster brick walls inside a house? There is no clear answer. You can use both dry plaster mixtures and solutions based on cement, gypsum or lime. Experts still recommend purchasing ready-made dry material. On the outside of the package, the manufacturer indicates the composition, purpose and method of preparing mixtures for plastering brick walls. Writes what work the mixture is intended for.

The purpose of plaster is to level the walls. Besides:

1. She carries protective functions, preventing moisture from entering the brick wall.
2. Increases thermal insulation and soundproofing of rooms.
3. Acts as decoration.

If we talk about the purpose, then plaster mortar for brick walls can be divided into several types:

1. Regular plaster is necessary for indoor work. After drying, you can apply, for example, wallpaper on it.
2. A special mixture can give the room additional moisture resistance.
3. Decorative composition for the most part used for exterior finishing. It can be of different colors and textures. It has high ductility and durability. Service life reaches 25 years.

Types of plaster mixtures for brick walls

Based on the type of most commonly used compositions, plaster mixtures for brick walls are divided into simple compositions, namely:

1. Cement.
2. Calcareous.
3. Products intended for gypsum plaster.

There are dry mixtures on sale that can be used to plaster walls consisting of several components:

1. Cement-sand.
2. Cement-lime.
3. Clay-lime and a number of others that can be used to process silicate brick walls.

Let's look at the plaster compositions that can be used to work on brickwork.

Considering this composition for plastering, we can say that it is universal. It is used for interior and exterior work. Advantages:

1. Durability. Can last up to 30 years.
2. Reasonable cost of the composition for plastering brick walls compared to other materials.
3. Plastic. The layer can be adjusted within a few hours.
4. Resistance to negative t 0 and high humidity. Cement-based plaster and sand are often used in the kitchen, bathroom and service areas, where there is high humidity.

However, with all positive properties the plaster mixture for brick walls in question has negative qualities:

1. It is necessary to thoroughly study the technology of applying it to brickwork.
2. The work requires a lot of effort.
3. The plaster solution applied to the work surface takes quite a long time to dry.

It is important to consider the nuances:

1. For example, the thickness of the plaster layer for brick walls should not exceed 30 mm.
2. To apply a layer of more than 3 cm, it is necessary to use reinforcing material.
3. When treating the facade of a brick building, lime is added to the cement-sand plaster mixture.

Gypsum mixtures for plastering brick walls

Gypsum-based compositions for plastering are a guarantee that brick walls will breathe due to high vapor permeability. To improve plasticity and increase adhesion, gypsum is added to the composition. By using gypsum you can achieve an increase in thermal insulation properties plaster mortar. Gypsum absorbs excess moisture from the walls, thereby improving the indoor microclimate.

Decorative mixtures for plastering brick walls

The mixture for brickwork looks advantageous. The plastering solution is applied to a previously prepared surface. Decorative mortar has a number of advantages:

1. Wall surfaces treated with decorative plaster look attractive and aesthetically pleasing.
2. The use of a decorative solution allows us to talk about improving water-repellent properties.
3. It is worth mentioning the antiseptic qualities of the decorative mixture when plastering.

There are a number of technologies to add texture and relief to walls. Most often, the fundamental component is synthetic resin. Various additives are used to give a beautiful appearance.

Set of tools for work

To prepare mixtures and plaster brickwork, you need to prepare a tool. Pre-prepared “working assistants” will save you from chaos and nervousness when performing a particular operation. The composition, as shown in the figure, includes:

1. , or more simply put, a trowel. They mix the composition and collect a portion of the finished solution for plastering. The site is leveled at the initial stage of the work process.
2. Falcon. Flat object rectangular shape On the one side. On the other hand, it has a handle. Placed on it ready-made composition for plastering, which is applied to the working area of ​​the wall.
3. Graters: regular and oval. They are designed to highlight corners.
4. Ironing iron. This tool levels the applied layer.
5. Spray. Serves to soften dried surfaces. You can use a brush to moisten the work areas.
6. Level. It is necessary to determine correct application mortar for plastering. It is advisable to use a tool measuring 1 meter or more.
7. The rule is a long strip for leveling mortar applied to a wall over a large area.
8. Two plumb lines.
9. You will need a pencil and a measuring tape.

Don't forget to stock up on a set of spatulas: small, medium and large.

Advice!

Pay attention to the quality of the tool. Any unevenness on the ironing edge can ruin the job. Buy the rule immediately before starting work.

Technology and stages of applying plaster to a brick wall

When processing brick walls with your own hands, you must adhere to existing SNiP. We are talking about applying layers of ready-made mortar when plastering brick surfaces:

1. Spray - this initial layer acts as a connecting link with the working surface. The thickness should not exceed 2 mm.
2. Primer is a viscous layer that is applied to the spray. Layer thickness up to 5 mm.
3. The covering is a layer for leveling the working brick surface.

When working, the rule is used with ends that protrude beyond the boundaries by 100-150 mm. The strip is passed along the surface without tearing off. The movements are wavy. Excess mortar is removed from brick walls.

When the work on plastering the brick walls is completed, the surface can be painted, primed, and so on.

Step-by-step instructions for plastering involve performing a number of sequential operations, without which you can forget about quality. Below we will tell you what should be done and in what order.

Preparatory work related to plastering brick surfaces

First of all, it is necessary to carefully examine the surface intended for plastering. Inspect and test the strength of old bricks. Identify loose joints on a brick wall. If any are found, they should be strengthened with cement mortar or foam.

Damaged parts of brick walls need to be repaired. Cover any identified chips and cracks. Get rid of sagging and old composition and apply priming. Loosen and get rid of old seams. The depression can be from 0.7 to one centimeter. In this case, the mortar and primer will penetrate deeply into the cracks of the brick walls and strengthen the surface. After the preparatory stage, you can begin plastering the brick walls.

Installation of reinforcing mesh when plastering brick surfaces

Before applying plaster to a brick wall, you need to install it, preferably a plastic one, which is fixed with metal hooks. They are driven into the seams between individual brickwork. Then:

1. Hooks are attached. The pitch should be 250 mm.
2. The mesh is mounted on the hooks. Cell – 10 mm.

To prevent rust, the mesh is treated with a special varnish or red lead. You can also use a mesh made of polymer materials.

Preparation of mortar for plastering

The composition for brick plaster includes cement and sand. At the preparation stage, the components for plastering are diluted with water and mixed thoroughly. It is important to obtain a homogeneous mass with good consistency.

If we are talking about ready-made mixtures for plastering, you must follow the manufacturer's instructions, which are located on the back of the package. It must be remembered that plastering mixtures made on the basis of cement and gypsum set quickly. Therefore, they should be diluted in small quantities.

The approximate consumption for cement mortar is 15 kg/m2. For gypsum with a thickness of the applied layer of 10 mm, the consumption is within 10 kg/m 2.

Installation of beacons during plastering

The slats are mounted on brick walls so that when working as a rule, it is possible to remove excess mortar.

Beacons are installed vertically. Step – 600/1000 mm. When installing slats, you must use a plumb line. The vertical pitch is 100 mm. The diameter of the hole that needs to be drilled is 6 mm. Then, dowels with screws are inserted.

Application of the solution

Applying plaster to a brick wall is possible:

1. Manually.
2. Or mechanized.

When the plastering composition is applied to a brick wall manually, use spatulas or a ladle. Layer thickness within 50 mm. If the value is higher, the layer will spread. The solution is leveled by the rule. Movements from bottom to top, zigzag. Excess mixture is removed.

If you need to plaster a large section of a brick wall, you can. When purchasing dry mixtures for plastering, pay attention to the manufacturer's recommendations. Where it is indicated that the solution can be applied by machine.

Removing beacons during plastering

To remove beacons from a brick wall, you will need a scraper and pliers. The algorithm of actions is as follows:

1. We determine the location of the guides using pre-set marks. Or use a magnet.
2. Using a scraper, part of the plaster is removed from the top of the guide and slightly pryed up.
3. The open part of the lighthouse is taken with pliers. Slowly stretches out. The movements should resemble twisting (winding).
4. It’s better not to pull everything at once, but to remove it approximately 150-200 mm at a time.

The workflow for removing 1 guide takes no more than one minute. After this, the places where the beacons were located need to be plastered with the same mixture.

Grouting the applied mortar during plastering

Grouting facade plaster on brick is the final process of leveling the walls. The work uses a grater or a special mesh with sandpaper. It is necessary to get rid of visible grooves and irregularities. It is better to grout when the mixture has not completely hardened. Otherwise, you will have to put in more effort.

Sand-lime brick plaster

Plaster by sand-lime brick has its own characteristics. Recommended use cement-sand mixture. The work is carried out in three stages:

1. Spray.
2. Base layer.
3. Finishing.

For more reliable fastening fiberglass reinforcing mesh is installed. More expensive, but better quality. At the final stage facade plaster the brick is painted or coated with a decorative composition.

Plastering brickwork inside the house is carried out in three stages, which are indicated above. Before applying the layer, it is necessary to prepare the surface for further plastering and prepare the solution, following the manufacturer's instructions. In your work, use the tool specified in one of the sections of this publication.

Features of plastering external walls

There are a number of features of outdoor work. You need to know how to properly plaster a brick wall. The process of plastering external brick walls is divided into several stages:

1. Preparing the base.
2. Arrangement of lighthouses.
3. Application of the finished solution.

Before plastering a brick wall, you must remove the old finish. Set up the beacons and, following the technology described above, begin work. Be sure to impregnate with primer. Important: the final layer thickness should not exceed 30 mm. To strengthen the plaster layer, reinforcing mesh should be used. At the finish you can apply a decorative coating.

Finally

Of course, applying plaster composition on a brick wall has a number of features. For example, smooth surface brick requires the use of reinforcing material. But, if you follow the technology and know the topic, plastering with your own hands will not create problems. The main thing is to act step by step and follow the recommended plastering technologies, good luck.

Plaster applied to a brick wall performs several functions. Firstly, it levels the surface. Secondly, it provides warmth and waterproofing without obstructing natural circulation air, gives the brick stove an aesthetic appearance. In addition, decorative plaster is aimed at additional decoration of the facade or interior.

The answer to the question of what is the best way to plaster walls remains relevant for many years. Modern market offers a variety of mixtures for outdoor and interior work. Until recently, plastering with cement-sand mortar was considered the most popular do-it-yourself finishing. Now available ready-made mixtures, to which various plasticizers and additives are added, allowing the processing of brick walls or oven surfaces to be processed more efficiently and quickly.

Application technology

There are several ways to properly plaster an object with your own hands. The first method is less accurate and is suitable for utility walls and non-residential premises. The process consists of the following steps:

• First you need to remove the old layer;
• Cement mortar is thrown onto the wall;
• The mixture is rubbed and leveled using a spatula;
• The surface is puttied and a finishing layer is applied.

It is possible to beautifully plaster the walls of residential premises with your own hands using beacons. The technology is more labor-intensive, but much more accurate and better. The essence of the work is as follows:

1. The beacon strip is attached to the work surface at a distance of 30 cm from the adjacent wall;
2. Installed throughout the entire treated area required amount lighthouses, the distance between which is 1-1.5 meters;
3. The entire structure sits on a cement-sand mortar and is leveled strictly;
4. Correctly checking horizontal lines should be done at three points (top, middle, bottom);
5. Beacons from the walls can be removed or left;
6. After the fixing solution has dried (4-5 hours), we perform additional fastening of the beacons, filling all the empty space;
7. The wall is watered abundantly, then the prepared solution is applied;
8. We level the mixture using a rule, moving it from bottom to top along the beacons, lightly pressing;
9. It is best to carry out the procedure several times until the working area is given the required condition.

The final finishing of the wall with your own hands should be done no earlier than after 14 days, which is required for the applied plaster to completely dry.

Classic plaster

You can prepare a cement-sand mortar yourself by mixing the components in the right proportions. A dry mixture is also available for sale, which is diluted with water. Cement plaster counts the best option for processing brick walls. The solution has the following advantages:

• Low price;
• High plastic characteristics, allowing work on the surface even several hours after application;
• Practicality and durability;
• Resistance to temperature fluctuations and other atmospheric influences.

The main disadvantage of cement mortar is the complexity of the work. In addition, the mixture takes a long time to dry, which affects the speed general process. When working with this type of plaster, certain rules must be followed. The application thickness should not be more than 30 mm. If the layer depth is 20 mm or more, installation of reinforcing mesh will be required.

When applied cement-sand mortar on external surfaces or in conditions of high humidity, lime is added to it. In cold rooms, a mixture with the addition of sawdust or pumice is used. The solution in its classic form is not suitable for finishing a stove.

Decorative processing

Plaster in the interior

Plastering a wall or stove is aimed at them perfect alignment before finishing. Along with traditional ways made with your own hands is increasingly used decorative cladding, which has a number of advantages and features. There are several varieties decorative plaster, which can be sold both in a ready-to-use form and in a bulk state requiring the addition of water.

The difference between this type of wall decoration is the ability to independently add it to the cement mortar. various components(granulation, shells, etc.), which allows you to create an original design for the facade.

Textured finish

This type of cladding is perfect for interior and exterior work on a brick, concrete or pre-plastered object. A correctly applied layer of wall decoration hides defects and smoothes out unevenness, thanks to the presence of large components. Before the main treatment, you need to remove the old coating and clean the surface.

We exclude plastering work in rain and at temperatures below +8 °C. Work with this type of finishing does not require the use of special expensive tools, and any person with minimal knowledge in the construction industry can handle its application.

There are several subtypes of textured installation:

• Fur coat - wall finishing with a rough coating on a cement-sand base;
• Lamb – a grainy, single-suit coating with roughness, intended for mineral surfaces;
• Bark beetle - resembles the bark of a corroded tree with grooves and a composite composition.

The finish in question can be used when treating oven surfaces as a finishing layer.

Lime is added to the mixture and marble chips. Each layer is applied with a rubber tool to a thickness of 5-6 mm and requires thorough drying. It is permissible to add different colors to the solution, which allows you to imitate precious metals, gloss or matte shade.

Structural decoration

This type of plaster is made from acrylic or silicate components and has a thin-layer structure. Used for interior and exterior work. The end result can be either with an almost flat surface (fine-grain composition) or with a certain relief (medium grain).

To obtain various design effects, it is better to apply structural plaster with your own hands in a circular motion using a spatula. Not recommended for use in high humidity or hot oven. The addition of coloring pigments to the mixture is also excluded. Structural plaster is supplied ready for use.

Furnace finishing

We will separately consider plastering the stove. The most proven and long-used material for this purpose is clay. It is better to start cladding the stove after the masonry shrinks and hardens. If the work is not carried out on a newly constructed surface, it is first necessary to remove old plaster and degrease the surface. The thickness of the next applied layer is a maximum of 5 mm. After completion, there is no need to rush to heat the stove; the lining should completely dry. If cracks form, they need to be slightly expanded and rubbed with the mixture used. The usual solution for finishing the stove is not suitable due to large temperature differences of the treated surface .
