Whitewash the ceiling without washing off the whitewash. Is it possible to paint the ceiling with water-based paint without washing off the whitewash? How to whitewash a ceiling - simple options for transforming a snow-white surface
Among the huge variety and modern possibilities for decorating shelves, whitewashing is still a relevant method of finishing it. Whitewashed ceilings are cheap and simple. In addition, sometimes you can refresh the ceiling without touching the previous finishing layer, then the question arises of how to whitewash the ceiling using old whitewash.
Whitewashing can give the ceiling an aesthetic appearance and update the overall interior of the room. The main thing is to properly prepare the surface yourself.
When implementing this idea, you need to pay attention to following points:
- Type of whitewash previously used;
- Strength of old coating;
- Types of contamination of old coating;
- The presence of cracks and chips in the old whitewash layer;
- Type and functions of the premises being renovated;
- Residents are allergic to whitewashing materials;
- Features of working with finishing materials.
In addition, before starting work, you should decide whether the previous layer of whitewash will be removed or whether it is easier to whitewash over the old layer.
It is important to understand that if old layer crumbles or comes away from the ceiling in layers, then new whitewashing cannot be done on it; it must be removed.
If some layers of the old coating peel off, they must be removed, and the unevenness formed in their place must be leveled with putty or putty.
How to whitewash a ceiling without washing off the old whitewash
Before carrying out Painting works, you should protect the room from all kinds of contamination.
And for the employee to protect himself:
- It is better to take the furniture out of the room;
- Close large furniture and floors protective coating;
- Protect your hands with gloves and your eyes with special glasses;
- If necessary, use a respirator;
- Put on a hat;
- You need to apply mounting tape yourself to the walls at the junction with the ceiling so as not to stain them;
- You don’t have to cover the tiles, and then just wash them (if you don’t use paint).
Then, having decided to whitewash the ceiling using the old whitewash, checking it for strength and leveling all the cracks and crevices, you need to get rid of stains on the old coating.
If there are any contaminants on the ceiling, then after applying a new finishing layer, they will be noticeable again, so it is necessary to get rid of them.
First, you should remove dust and cobwebs from the ceiling using a regular rag soaked in warm water. Next, they get rid of more serious contaminants, such as mold, grease and rust. I wash off the mold with soap and water or a special anti-mold agent. If the room often has high humidity, that is, it is prone to the formation of mold on the ceiling, then the entire work surface It is better to pre-treat with an anti-mold solution.
Rust must be wiped off with a regular damp cloth, and after that you need to walk over the cleaned area with a 10% solution copper sulfate. Get rid of greasy stains using ordinary soda, which is diluted in water in high concentration. After removing the stain, wash off the soda clean water.
It should be noted that yellow spots on the ceiling will also show through the new clean white layer, so they need to be bleached. To do this, add Whiteness to the water and wash off the stains with a regular rag.
Whitewash primer for ceilings
In order for the new whitewash to lay smoothly and without streaks, the entire working surface must be prepared. To do this, the entire ceiling must first be primed.
It is best to use a primer deep penetration to ensure good adhesion of the new finishing layer to the old one.
The ceiling must be primed both after removing old whitewash layers before new treatment, and when applying a new finish to old surface, covered with chalk or lime.
The following tools are used for priming:
- Roller;
- Brush;
- Rag or sponge.
For priming, it is better to resort to rollers, but if it is impossible to purchase this tool, the others listed above will also work. After the surface has been treated with a primer, it will need to dry. The duration of this process is indicated in the instructions for using the primer and usually takes less than a day. This is where the preparation ends.
Glue for whitewashing ceilings
To whitewash a ceiling, it is customary to add glue to the whitewash mixture.
Adhesive base leads to the following consequences:
- The service life of the whitewash coating is extended;
- The strength of the finishing layer increases;
- The removal process is complicated old whitewash.
Considering all these points, it is best to add glue, because then the issue of repairing the ceiling in the apartment will arise much less often.
It is best to add regular wood glue to the whitewash mixture, then the ceiling in the room will be able to retain its presentable appearance longer.
Whitewashing for the ceiling: types
When whitewashing a ceiling, first of all, you need to decide on its appearance. The choice is usually based on the cost of the materials used, the type of old coating and the difficulty of applying a new finishing layer.
There are three common types of whitewashing today using:
- Mela;
- Lime;
- Water-based paint.
Last view It would be more accurate to call it painting, but for simplicity it can be attributed to the concept of whitewashing. Whitewashing with chalk and lime are more environmentally friendly methods, but chalk tends to crumble, and some people are allergic to lime. Water-based paint gives the ceiling a more aesthetic appearance, but after such treatment the surface does not “breathe”.
It is important to know that you cannot whitewash the ceiling with lime if the old layer is treated with chalk, and, conversely, it is not allowed to whitewash the old lime layer with chalk, as unsightly stains will remain.
To whitewash with chalk, you need to prepare a solution of 3 kg of chalk and 30 g of wood glue, which must be mixed in 5 liters of water. It is better to use warm water to better dissolve the powders in it. You can add blue to this mixture, as it will make the ceiling snow-white. The amount of blue will depend on the desired shade of the ceiling. In these proportions, 15-25 g of this substance is recommended.
To whitewash a ceiling with lime, you need to prepare the solution as follows. About 2.5 kg of lime needs to be diluted in a liter of warm water, 100 g of salt pre-mixed in water is added to this composition. Similar to the chalk solution, blue is added to this mixture. After all procedures, the resulting concentrate is diluted with ten liters of water.
Water-based paint is purchased ready-made in the store. It should be noted that the consumption of such paint is quite large, and the shades can be different, therefore, in order to avoid spotting the ceiling, you need to purchase paint in advance with a reserve. This type of treatment is best used for the bathroom, since the painted ceiling can be washed. To get the most white ceiling can you cover it acrylic paint Snowball, or you can paint the ceiling different colors.
Apply whitewash to ceiling slab should be applied in 2 or even 3 layers to completely cover the previous layers. In this case, the first layer should be applied perpendicular to the sunlight coming from the window, and the second parallel to them. You can apply a new layer with a brush or roller only after the previous one has completely dried. If the technology is violated, then bubbles appear.
Whitewashing ceilings: stages
Whitewashing ceilings is not as complicated a process as it might seem at first glance. The main thing is to act logically consistently so as not to miss anything important.
Therefore, to simplify the repair process, the following stages of whitewashing the ceiling can be distinguished:
- Determine the type of old finish (run your finger along the ceiling, if there are white marks, then chalk, if there are no marks, then lime);
- Decide to remove old layers;
- Check the strength of the old coating when deciding to whitewash over the old finish;
- Remove all poorly attached layers of the old layer;
- Correctly seal all unevenness, cracks and cracks (the mixture is applied with a spatula perpendicular to the crack, and then the excess is removed with the same spatula, but in parallel; you can use putty);
- Rub over all irregularities with pumice or sandpaper after the putty has completely dried;
- Remove all contaminants depending on their type;
- Treat the entire working surface with a deep penetration primer;
- Select the type of new whitewash based on the type of old whitewash;
- Prepare a whitewash mixture or buy a water-based emulsion in the store;
- Apply several layers of whitewash to the ceiling.
By performing the process step by step, the whitewashed ceiling will turn out beautiful and clean.
Whitewashing the ceiling and walls (video)
When making repairs, it is not at all necessary to spend money on expensive tensioning or suspended ceilings. After all, you can very simply and quickly create beauty with your own hands.
Despite the fact that today, with the abundance of finishing materials on the market, whitewash is used much less frequently, it can still be found quite often in premises. And during the renovation of such premises, the question often arises as to whether it is possible to apply water-based paint to the whitewash without cleaning the wall from lime.
When painting walls, we must take care to create the highest quality adhesion of the paint coating to the surface. Therefore, whitewash, which clearly does not contribute to such adhesion, according to the rules, must be removed.
Experts do not advise carrying out such painting, since the whitewash will simply peel off the wall and remain on the roller. The only exception is that the whitewash layer is very thin and adheres very firmly.
Painting over whitewash - use a primer
As we said above, the paint needs good adhesion to the wall. Otherwise, it will begin to fall off, if not immediately, then certainly after a short period. To ensure such adhesion it is necessary to use a primer, which is applied to the whitewash layer. After the primer has dried, test the layer for strength by lightly scratching the surface. If the whitewash treated with primer remains strong, then painting can be done.
Paint selection
Many people ask, is it possible to apply water-based paint to whitewash? Actually this one finishing material is the only adequate way to paint such a problematic surface. Moreover, such paint does not require the use of a primer, having the function of the latter itself. But, again, it is necessary to ensure the strength of the whitewash layer.
If you plan to apply oil paint or enamel to the whitewash, then it is better to refrain from this step, as the result will be disastrous.
When not to paint: how to clean old whitewash from walls or ceilings
Experts still do not recommend painting without first removing the whitewash. And therefore ideal solution in this case, it is the removal of a layer of this very whitewash. There is no single master class here, and it all depends on the thickness of this layer and how firmly it holds:
- Thin layer. Despite its insignificant thickness, it is very difficult to remove. Significant impact will be required, and a grinding machine can provide this;
- Medium thickness layer. If this is exactly what you get, then this whitewash will most likely hold up well. However, it’s still easier to pick it up and tear it off the wall. We use a roller with good pile, generously wetting the walls or ceiling with it;
- Thick layer. As a rule, such a layer of whitewash adheres very mediocrely, so in most cases it can be removed with an ordinary spatula, after wetting it first.
Some whitewash removers
- Paste. This method allows you to rid the walls or ceiling not only of whitewash, but also of dust and dirt;
- Soapy water. The solution is prepared as follows: for 10 liters of water, take 2 tablespoons of grated soap and 5 tablespoons of soda. It is necessary to wipe the whitewash layer with this solution until it completely disappears;
- Wallpaper remover. Apply the remover to the whitewash surface and leave for a while. After this, you can work with a spatula and clean the wall.
The outer wall of the house is whitewashed. Is it possible to apply a primer?
It is possible and even necessary. After all paintwork, which is influenced by many natural factors, is subject to a lot of pressure and will not last long. Primer, when it comes to special façade models, is ideal for this.
If you are still going to paint
This solution should only be used if the whitewash is applied in as thin a layer as possible. No other paint other than water-based paint is used. As an alternative, you can re-whitewash, but with the addition of color, in order to give the walls the required color.
It is recommended to whitewash or paint ceilings only after the old finish has been removed. However, this matter is quite complicated. Removing old chalk or lime from the ceiling is long and tedious. In addition, after this a lot of dirt remains in the house. Previously, glue was added to the chalk solution before whitewashing. If the surface is finished with just such a product, cleaning it becomes a pain. Therefore, many owners of houses and apartments would probably like to know whether it is possible to whitewash the ceiling using old whitewash, and how to correctly perform such an operation.
What you need to know
In principle, you can paint or whitewash ceilings without removing the old coating. But not in all cases. So, for example, whitewashing a ceiling over old whitewash with chalk is extremely undesirable if it is covered with lime (and, accordingly, vice versa). Otherwise, sloppy streaks will definitely appear on the ceiling. If you don’t want to clean off the old coating, you should whiten the ceiling with the same product that was used before. You should also not use lime or chalk if the surface was previously treated with water-based paint. The surface simply will not become white. The ceiling will remain yellow, no matter how many layers are applied.
Using paint - is it possible?
Many owners of houses and apartments are wondering, among other things, whether it is possible to whitewash the ceiling over old whitewash with water-based emulsion. It is considered acceptable to use this remedy. But only if the layer of old finishing is not too thick and adheres to the ceiling firmly enough. Under no circumstances should oil paint or enamel be applied to whitewash. When using them, the old coating will still have to be removed.
Preparation for finishing
If you decide to perform such an operation as whitewashing the ceiling using old whitewash, before starting processing you will have to carefully prepare the old surface. Chalk on a layer of plaster usually lies flat. Lime may come off in chunks. Therefore, in the latter case, before whitewashing, you need to check the entire ceiling for the presence of such detachments. Of course, all loose pieces should be removed with a spatula. After performing this operation, there will, of course, be some unevenness on the ceiling. They need to be sealed with a special chalk putty or thick lime mortar with the addition of a small amount of PVA glue (depending on the type of old finish). Of course, you need to coat all the cracks and chips on the surface.
Before starting to level the ceiling, it is advisable to go over it with a damp cloth in order to remove dust, cobwebs, etc. It often happens that the old chalk or lime coating has yellow. Once the new finish is applied, that yellowing will likely still show through. Therefore, before starting work, such a discolored surface should be bleached. Such a need, for example, will definitely arise when finishing the kitchen. Yellow ceilings They also happen if one of the owners smokes right in the apartment. It is not difficult to whiten such a surface. It is enough to simply add a little inexpensive “Belizna” product to the water in which the rag is dipped during cleaning. If the ceilings are very yellow, you should go over them with a roller soaked in the prepared solution. Next, you should wait until the surface dries.
Whitewashing the ceiling using old whitewash: technology
Chalk and lime usually do not adhere very well to concrete. Therefore, a ceiling previously finished with such a product should be treated using a spray bottle rather than a roller. In this case, the surface will be smooth and neat. A roller can also be used. But when using this tool during work, you will have to carefully ensure that no streaks remain on the surface. Of course, you need to whitewash ceilings over old lime or chalk layers not in one, but in at least two or three layers.
Using water emulsion
Having asked the question, you should, of course, decide on the type of finish used. Chalk and lime are used extremely rarely today when decorating ceilings. In most cases, apartment and house owners use water-based paint. This product is applied to the ceiling surface much more evenly. In addition, the water-based emulsion does not peel off over time. But of course, such a finish will last a long time only if it is applied correctly.
Before painting with water-based paint, the bleached ceiling should be primed. In this case, a special deep penetration agent should be used. After the primer has dried, you need to test the old coating for strength. To do this, just try to scratch the ceiling with a spatula. If the old coating is easily removed, it is better not to risk it and remove it anyway. If the chalk or lime soaked in primer holds tightly, you can start painting.
Sometimes owners of apartments and houses finish whitewashed ceilings with water-based emulsion and without prior priming. This is also acceptable. But only if very high-quality paint from a good manufacturer is used.
Basic rules for whitewashing
Of course, before starting such an operation as whitewashing the ceiling using old whitewash, the room needs to be prepared. Floors and furniture should be covered with technical plastic film. You need to wear rubber gloves on your hands. This is especially important if slaked lime is used for processing. As you know, it can severely corrode the skin.
All doors and windows must be closed before starting to whitewash the ceilings with water-based emulsion, lime or chalk. Otherwise, after drying, unsightly stains and stripes will appear on the ceiling.
Use of special tools
The sprayer gives a very thin layer of finish. Therefore, whitewashing the ceiling over old whitewash with water-based paint when using this tool should be done in at least three layers. This allows you to get a smooth, completely white and clean surface. Before applying each subsequent layer, be sure to wait until the previous one has completely dried. This rule, by the way, is observed both when using a spray gun and a roller.
Is it worth finishing the surface without pre-cleaning?
So, we found out whether it is possible to whitewash the ceiling using old whitewash. In principle, this is allowed. If all the recommendations listed above are followed, the owner of an apartment or house can ultimately obtain a fairly even and beautiful coating. However, unfortunately, such finishing will have to be corrected in the future sooner than if the ceiling had been previously cleaned.
Therefore, before deciding to whitewash without removing the old layer, you should think carefully. The lime sticks to the ceiling quite firmly. Therefore, if the surface is finished with exactly this, applying a new layer without removing the old ones still makes some sense. But chalk can be removed from the ceiling very easily - just with a rag and water. Therefore, in this case, it is more advisable to pre-clean the surface.

How to whitewash a ceiling using old whitewash
Anyone who has started a renovation should remember that a beautiful top will highlight all the advantages of the room. Whitening has always been the most popular decoration method for renovations. Therefore, every year many people are interested in how to whitewash or paint a whitewashed ceiling with water-based paint, chalk or lime.
According to the rules, before renewing a ceiling painted with whitewash, you need to wash off old material. Only then do they apply new white. But few people think that it is quite possible to apply it to the old coating. new paint and without rinsing. But in order to be pleased with the result, you need to know how to paint the ceiling without washing off the old whitewash.
Is it possible to paint the ceiling without washing off the whitewash?
Since it is not always possible to paint a whitewashed ceiling without washing off the whitewash, let’s look at when this is allowed and how. You cannot whitewash the ceiling with whitewash over the old one if:
- There are cracks
- The surface is uneven
- There are stains, rust or mold
- The previous layer of whitewash is very thick
- There are swollen areas
In these cases, washing off the old layer (complete or partial) is necessary. You don’t have to completely remove the old coating, cleaning only the loose areas (more on this in the next chapter). You can whitewash or paint the ceiling over whitewash if:
- The previous coating is quite thin
- No cracks
- Nothing crumbles
Now about what you can use to paint the ceiling after whitewashing. It is very important to know the type of coating before starting work. Chalk does not cover lime and vice versa. Chalk and lime do not whiten over water-based paint - the ceiling will be yellow regardless of the number of layers. It is not recommended to apply enamel and oil paint to lime and chalk.
For rooms with high humidity you need to use a special composition for the ceiling area. It will protect the coating from fungus, discoloration and rapid shedding.
Preparing to finish a whitewashed ceiling
Before you begin, it is important to think about your own protection. In your work you should use:
- Rubber gloves for hands
- Respirator
It is necessary that no one in the household is allergic to the new coating.
We take the furniture out of the room and cover the floor with plastic wrap so as not to stain it. Doors and windows must be kept closed, otherwise streaks may appear after the ceiling dries.
If the old coating has peeled off in some places, it must be scraped off in those places with a spatula, and then sealed with chalk putty (if the ceiling is chalk) or lime mortar with PVA glue mixed into it (if it is covered with lime). We also treat existing chips and cracks in the ceiling.
If the ceiling is smooth, its front new finishing wipe with a cloth to remove dust. A yellowed ceiling can be treated with “Whiteness”, applying it either with a rag or with a roller.
To ensure that the new coating adheres better, it is recommended to prime it using a deep penetration acrylic primer. After this, scratch the surface; if it does not crumble, you can paint it. But in the case of applying water-based paint to chalk, a primer is not necessary, since the water-based paint itself will bind the old whitewash and will adhere well.
How to whitewash a ceiling without washing off the old whitewash
Let's look at how to whitewash a ceiling using old whitewash. To make the coating last longer, you can add wood glue to the composition. This makes the layer more durable and appearance will please the eye much longer.
How to paint the ceiling after lime whitewashing? Best of all - the same lime. To prepare mortar, take:
- Two and a half kilograms of lime
- 10 grams of salt, previously soaked in water
- A little blue
Mix everything and add water. The final volume of the product will be approximately 10 liters.
How to paint a ceiling with chalk whitewash? You can prepare the chalk solution yourself. Compound:
- 10 liters of water
- 5 kilograms of chalk
- 50 grams of wood glue
The consistency should be such that the solution does not run off the knife. If the solution flows, add more chalk. If you are afraid that the surface will have yellow tint, add a little blue.
The technology for applying chalk, lime and water-based paint is approximately the same. The main thing is to ensure that the composition lies evenly.
If you work with a roller and brush, you need to first make strokes perpendicular to the windows, and then parallel ones. This is done so that at the end of the work the stripes are not visible in the light.
How to paint a ceiling without washing off the old whitewash using a roller? The roller allows for a very precise application. The composition will need to be applied twice. Will be needed additional tools: a container to dilute the solution, a painting tray, a brush (for processing joints). The disadvantages include the possibility of staining the walls. When whitewashing you need to adhere to the following algorithm:
- Pour paint into a special tray;
- Place the roller in the container and roll it down the slope. This way the paint will be distributed evenly over the roller;
- Paint perpendicular to the windows;
- Wait for it to dry;
- Paint a second time parallel to the window;
- Treat the joints with the wall.
But if you choose to paint with a spray gun, you will have to repeat the whitewashing process at least three times: the layer that the spray gun produces is very thin. If you maintain the correct consistency (more fluid) and make sure that there are no lumps, then application will be easy, and the result will please you.
You can also paint or whitewash with a brush. It is inexpensive and widely available. The downside is a lot of splashing when applied.
Regardless of which tool is selected, the next layer can be applied only after the previous one has completely dried.
Renovating a room is not easy. But if you approach this issue wisely, then it is possible to do such work yourself. And the question of how to whitewash the ceiling without washing off the whitewash will not become an obstacle to renovation.

To check the consistency, use a regular knife: if the solution flows easily from the blade, then you need to add a little more chalk so that the liquid acquires the desired viscosity. To prevent the whitewash from giving off a yellowish tint, blue is added to the solution.
Lime whitewash It is resistant to moisture, but has a rather pungent odor and takes a long time to dry. There is no such thing as perfect white. One of the advantages is that lime mortar seals small cracks and crevices well. Plus, lime has good bactericidal properties.
The solution is prepared simply: 2.5 kg of lime, 100 g of salt (pre-soaked in water) and a little blue (already diluted) are thoroughly stirred in a liter of water. All ingredients must be mixed well. Warm water is gradually added to the resulting mass (the total volume of the solution is 9-10 l). For people allergic to lime, it is better to pay attention to other whitewash options.

Methods of applying the solution to the ceiling
There are three main ways to whitewash a ceiling. All of them are easy to perform, but some nuances should be taken into account.
Brush
The simplest and most popular way to apply whitewash to a small area of flooring is to apply whitewash. Dipping the brush into a container of white, use it to make W-shaped gestures across the surface, thus applying layer after layer.
When applying the solution with a brush, you should remember that the first level is applied from the window, and the second - on the contrary, so that no brush marks remain.
Roller
If you paint with this tool, the whitewash will lie smoothly and no streaks or plaques will form.
Just one roller will not be enough. Additionally, you will need a container for the solution, some kind of stirring object and a special painting tray. In addition, you will have to stock up on a small brush to cover the ceiling at the joints - you won’t be able to do this neatly with a roller.
Main advantages of the roller:
- whitewashing material is saved;
- the coating is applied in an even layer, without drips or streaks;
- no bristles remain;
- if the roller is equipped with a long handle, a stepladder is not needed;
- high productivity over large areas.
Sprinkler
You can apply whitewash using a spray gun (sprinkler) or a vacuum cleaner (if you have one) special nozzle).If you carry out the procedure correctly, you will get a good result.
The device works like this: under pressure, air enters the spray gun, takes the required amount of white and sprays it along with the air.
To regulate the flow of paint, the sprayer has special hole, when closing and opening the jet intensity is adjusted.
Before painting, the solution is thoroughly mixed, poured into a container and closed.
Important! The container must first be moistened. This ensures better adhesion of the mixture to the surface.
When applying whitewash to the ceiling, be sure to monitor the surface, trying to prevent the appearance of drops, which then lead to stains.
To apply the paint evenly, spray it in a circular motion. In this case, the spray gun must be kept at a distance of 70-100 cm from the surface.
For a better result, you will need to apply 2-4 layers, which will hide minor defects.
Solution application technology
Whatever whitewashing method you choose, there are general rules carrying out the work:
- During drying, avoid drafts and open air. sunlight. Otherwise, there is a high risk that the paint will crumble.
- It is better to apply lime mortar to a dampened ceiling. Then the whitewash will adhere better and will not leave streaks.
- There is no need to rush. Layers should be applied in even circles.
- Regardless of the chosen finishing method, you should first brush over the joints and all corners, and only then begin the main work.
- Do not make the mixture too thick - the consistency should resemble fresh sour cream. Otherwise, the paint will not apply evenly.
- To achieve a homogeneous layer, filter all components, freeing the solution from excess debris and lumps.
- At least two layers should be applied, observing a technological break between each one. This way you can achieve uniform whitening.
- It is advisable to remove the previous whitewash completely. Then the chances of the absence of streaks and stains will increase.
- The overlaps between layers should be 4-5 cm. This will allow you to avoid unpainted areas.
Did you know? Chalk is one of the components earth's crust. The percentage of its content in it is 4%. And more than 20% of sedimentary rocks consist of chalk and limestone.
Precautionary measures
Compliance with safety precautions is required for all types of repair work. And whitewashing is no exception. First of all, you should protect your body, eyes and respiratory organs. Therefore, finishing must be done in safety glasses, a respirator (can be replaced with a gauze bandage soaked in water), gloves, a headscarf and overalls (the ideal option is overalls).
As you can see, whitewashing with your own hands is possible for anyone who decides to refresh their home. By following the above rules, even a beginner will be able to finish the ceiling almost perfectly.
Painting, although undesirable, is possible. And only in those cases if:
- There is a very thin layer of whitewash;
- It holds up well, does not crack or crumble.
Otherwise, when painting, it will be removed with a roller. And in the end we will get a poorly painted and unaesthetic surface.
Before applying paint, the surface is coated with a deep penetration primer. Then, it is given time to dry completely. And then they test the feasibility of painting by scratching the surface. If it is easily damaged and removed, then it is better not to risk it and not paint it. In this case, you cannot do without completely cleansing the surface of chalk. Well, if the primed surface passes the test, then you can safely start painting.
If water-based paint is chosen as the paint for painting the surface, then you can do without a primer. This type of paint itself will act as a primer, binding and securely fixing the chalk particles.
If the layer of chalk or lime is thin, holds tightly and does not have swelling or cracks, then water-based paint applied to it will last for many years.
- Available thick layer whitewash with cracks and swollen areas;
- If you plan to apply oil paint or enamel.
In order not to take risks and end up with a bad result, it is better not to save time and effort, but to immediately remove the layer of chalk or lime. Then the result will be much better and will last for many years.
If it is not possible to paint the ceiling or walls over the old coating, then you need to clean it off. This can be done depending on the thickness, applied layer and quality.
But in any case, the first thing you need to do is take care of all the furniture in the room. It must be closed with film and tape to avoid damage.
A small layer can be removed using a fleecy roller. You need to wet it and clean the ceiling, rinsing it periodically. You can also use a brush for these purposes.
If the layer is thick, but does not adhere very well, then it can be removed with a spatula, after wetting it. Then you need to fill all the cracks and level the surface. And only then you can sand and prime it, preparing it for painting.
Well, the last case: the lime is applied in a thin layer, which adheres well. Most often this happens if glue was added to the solution for strength. It must be removed using a grinding machine.
Be sure to prime the surface before applying paint. To do this, you can use a special primer, drying oil or wallpaper glue. The choice should be made depending on the paint that will be applied subsequently.
After all the preparatory work on the ceiling and walls is completed, you can proceed to painting. This can be done with a roller, wide brush or spray gun. When using the latter, you need to apply the paint in three layers, allowing each to dry.
