It is recommended to whitewash or paint ceilings only after the old finish has been removed. However, the matter is rather complicated. Cleaning old chalk or lime from the ceiling is long and tiring. In addition, there is a lot of dirt left in the house after that. Previously, glue was added to the chalk solution before whitewashing. If the surface is finished with just such a tool, cleaning it completely turns into torment. Therefore, for sure, many owners of houses and apartments would like to know if it is possible to whitewash the ceiling according to old whitewash, and how to perform such an operation correctly.

What you need to know

In principle, it is possible to paint or whitewash ceilings without removing the old coating. But not in all cases. So, for example, it is highly undesirable for old whitewashing with chalk if it is covered with lime (and vice versa, respectively). Otherwise, sloppy stains will definitely appear on the ceiling. If you don’t want to clean off the old coating, the ceiling should be whitewashed with the tool that was used before. You should also not use lime or chalk if the surface has been previously treated. water emulsion paint. The surface simply does not gap. 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 on old whitewash with a water-based emulsion. It is believed that the use of this tool is acceptable. But only if the layer of the old finish is not too thick and is firmly attached to the ceiling. In no case should oil paint or enamel be applied to whitewash. When using them, the old coating will still have to be removed.

Finishing preparation

In the event that you decide to perform such an operation as whitewashing the ceiling using old whitewash, you will have to carefully prepare before starting processing old surface. Chalk on a layer of plaster usually lies flat. Lime can also come off in chunks. Therefore, in the latter case, before whitewashing, you need to check the entire ceiling for the presence of such delaminations. Of course, all loose pieces should be removed with a spatula. After performing this operation, irregularities will, of course, remain on the ceiling. They need to be repaired with a special chalk putty or a 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 lubricate all the cracks and chips on the surface.

Before proceeding with it, 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. After application new finish, this yellowness, most likely, will still shine through. Therefore, before starting work, such a discolored surface should be bleached. Such a need, for example, will necessarily arise when finishing the kitchen. Yellow ceilings there are also cases when one of the owners smokes right in the apartment. It is easy to whiten such a surface. It is enough just to add to the water in which the rag is dipped during cleaning, a little inexpensive Whiteness product. If the ceilings are very yellow, they should be passed with a roller soaked in the prepared solution. Next, you should wait until the surface dries.

Whitewashing the ceiling on the old whitewash: technology

Chalk and lime usually do not adhere very well to concrete. Therefore, the ceiling, previously finished with such a tool, should be processed using not a roller, but a spray gun. In this case, the surface will be smooth and neat. A roller is also allowed. But when using this tool during the work, you will have to carefully monitor that there are no stains on the surface. Of course, whitewash ceilings on old lime or chalk layers you need not one, but at least two or three layers.

Using a water emulsion

Having wondered about the old whitewash, one should, of course, decide, among other things, on the type of finish used. Chalk and lime are rarely used today in the design of floorings. In most cases, the owners of apartments and houses use water-based paint. This tool is applied to the surface of the ceiling much more evenly. In addition, the water emulsion does not exfoliate over time. But of course, such a finish will last a long time only if it is applied correctly.

Before painting, the bleached ceiling should be primed. In this case, a special means of deep penetration should be used. After the primer dries, 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 still remove it. If the chalk or lime impregnated with a primer hold tight, you can start painting.

Sometimes the owners of apartments and houses finish whitewashed ceilings with a water-based emulsion and without prior priming. This is also allowed. 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 with old whitewash, the room needs to be prepared. Floors and furniture should close the technical plastic wrap. Should be put on hands latex gloves. This is especially important if it is used for processing. As you know, it can severely corrode the skin.

All doors and windows must be closed before whitewashing the ceilings with water-based emulsion, lime or chalk. Otherwise, ugly stains and stripes will appear on the ceiling after drying.

Application of special tools

The sprayer gives a very thin layer of finish. Therefore, whitewashing the ceiling on old whitewash with water-based paint when using this tool should be done in at least three layers. This allows you to get a flat, completely white and clean surface. Before applying each subsequent layer, be sure to wait until the previous one is completely dry. This rule, by the way, is observed both when using an airbrush and a roller.

Is it worth it to finish the surface without pre-cleaning?

So, we found out whether it is possible to whitewash the ceiling on the old whitewash. In principle, this is allowed. Subject to all the recommendations listed above, the owner of an apartment or house can eventually get a fairly even and beautiful coverage. However, to correct such a finish in the future, unfortunately, will have to be done earlier than if the ceiling had been previously cleaned.

Therefore, before deciding to whitewash without removing the old layer, you should think carefully. Lime is held on the ceiling quite firmly. Therefore, if the surface is finished with it, applying a new layer without removing the old ones still makes some sense. But the chalk is 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.

Until recently, whitewashing was the most popular ceiling design option. She is chosen for a number of positive qualities. Such as low cost, easy application and easy renewal of the coating. Now people have begun to pay more attention to this issue. The easiest way to change whitewash to a different finish is to paint it. In this article, we will tell you how to do it quickly and correctly.

Can whitewash be dyed?

Undoubtedly, it is possible, but only in certain cases and in a certain way. The main condition is the good condition of the whitewash itself. Thin application layer and no cracks. Otherwise, when applying paint, the whitewash will stick to the roller and crumble.

How to paint whitewash

First, coat the whitewash with a primer with a deep penetration property. Wait until it dries completely. Then check how well it is fixed. If it easily falls off, then it is better not to paint the surface. In this case, you will have to completely clean the ceiling from whitewash. If the surface of the primer turned out to be reliable, it can be painted.

Water-based paint on a whitewashed ceiling

This type of paint can be applied to whitewash without prior priming. Of course, if the chalk or lime layer is thin and even. This type of paint itself can be a certain kind of primer. If you apply another paint on it, then the coating will be very reliable and durable.

When is it better not to paint the ceiling with whitewash

• If the whitewash was installed a long time ago.
• Has bumps and swelling.
• If you are going to apply enamel or oil paint.

Surface preparation for painting

You can try to correct roughness or swelling with a stiff brush. Apply primer or emulsion paint. Take out the carpet before the procedure upholstered furniture, interior items and personal belongings if possible. Cover surfaces with cling film. Wear protective clothing, goggles, mask. You can start coloring. For saturation, repeat in several layers.

For coloring, you can use any construction paint except for oil. Paint can be of various colors and price categories.

As mentioned in the article, you can apply paint to whitewash. But still, we advise you to spend time and completely remove the whitewash before painting for a better result. We hope this information will be useful to you.

If you decide to make repairs with your own hands, then the first thing in such a repair is to whitewash the ceiling with your own hands. And in order to properly perform this work, you are offered the following algorithm of actions.

Preparing the ceiling for whitewashing

If you skip this step, the new whitewash will soon crumble. Preparation is especially important if the ceiling was whitewashed with lime, and now you decide to whitewash it with chalk or paint, or vice versa. It is clear that mechanical impurities ( greasy spots, dust, etc.) also need to be washed off if you want to whitewash the ceiling yourself.

To determine how the ceiling is whitewashed, you need to moisten the old whitewash. If it has darkened and does not stain the finger, then the whitewash was lime. If the surface is easily erased, there was a chalky whitewash. Water-based paint will remain unchanged.

Now consider how to quickly wash off the old whitewash from the ceiling:

1. Cover the floor and furniture that you could not take out with polyethylene or other protective waterproof material;
2. Prepare a warm soapy solution, sponge or brush;
3. Moisten the old whitewash in squares, because. if you wet the entire ceiling, it will dry out and you will have to repeat the moistening;
4. Scraping wet areas with a hard spatula, substitute a pallet to avoid soiling the floor as much as possible;
5. Wash off the remaining whitewash with a wet sponge.

Even if the old coating is not contaminated, it still needs to be moistened so that the new one is better absorbed.

So, you were able to remove the whitewash, it's time to move on to the next step:

• joints ceiling tiles if necessary, glue with a special tape (serpyanka).
• The washed ceiling, if necessary, putty to level and eliminate possible cracks.
• After the putty has dried, rub it with sandpaper so that the entire surface becomes smooth, and prime the entire ceiling area.

Choosing what to whiten

chalk

One option is to whitewash the ceiling with chalk. It is used by those who prefer whiteness and freshness. To prepare chalk whitewash for 10 sq.m:

• Pour 30 g of glue (carpentry, PVA or Bustilat) into warm water or dissolve finely planed laundry soap;
• Stirring thoroughly, slowly pour in the sifted chalk (about 3 kg);
• To avoid a yellowish tint and to enhance the whiteness, add about 20 g of blue to the solution.

Lime

Another option is whitewashing with lime, which is chosen because of its bactericidal properties and the ability to fix small cracks. In this case, for 10 sq.m, dilute in warm water 1.7 kg of lime and 40 g of blue.

To dilute the whitewash correctly, check its consistency. To do this, lower a metal object into the solution and, taking it out, look - if the solution is too liquid, the whitewash will drain from it without leaving a trace. Then add chalk or lime in small doses until the solution does not drain from the object without a trace.

Tool preparation

You can whitewash the ceiling with a brush, roller, spray gun or vacuum cleaner with an air blowing function. However, the option with a spray gun or a vacuum cleaner for home conditions is less suitable, because. in a small area, splashes will settle not only on the ceiling.

First you need to choose a brush for whitewashing, because the quality of work depends on its condition. It is better to buy a 15-20 cm wide natural bristle brush specially designed for your purposes. Soak it in warm water for several hours before use. This is how you achieve wooden handle brushes will swell and fix the bristles. Then they will not remain on the whitewashed surface. And after work, rinse it under running water.

Rollers will allow you to whitewash the ceiling faster, and the quality will be better. There are no features when choosing them and they do not require a separate description. To use the roller, you will need to buy a special pallet (ditch).

whitewashing process

If you are whitewashing the ceiling with a brush, apply strokes first perpendicular to the windows (towards the light source) and the final layer parallel to the windows. Then, when dry, no streaks will be visible.

More easy process whitewashing will ensure the use of a roller:

Pour the whitewashing solution or paint into a special tray (ditch), dip the roller into it and roll it along the slope of the tray so that the solution (paint) is evenly distributed over the surface of the roller, and the excess flows off the roller.

When making layers of whitewash with a roller, direct them as when painting with a brush - first towards the windows, then parallel to the frames. When driving the roller across the ceiling, make overlaps of about 5 cm so as not to leave unpainted areas. Do not forget that in the joints of walls and ceilings, where the roller does not reach, it is better to use a brush.

Alternative option: whitewashing the ceiling with “water emulsion”

The best thing is not to suffer with chalky or lime mortars, use water-based paint when whitewashing the ceiling. It allows you to evenly paint the ceiling and looks more beautiful.

Only the preparation of the ceiling in order to paint the ceiling after whitewashing requires special care. Moreover, of all types of paints, only a water-based emulsion will provide the best "sticking" to the old whitewash and will not peel off.

The second coat of paint is best applied perpendicular to the first: this way there will be less streaks

Also, in order to qualitatively apply whitewash paint, it is better to paint in two layers, and the second layer can be applied only after the first has dried.

1. Calculate the cost of whitewashing, taking into account the amount of materials required. To do this, knowing the consumption of paint, chalk or lime, glue, blue and other components, calculate their cost. Add the cost of tools (brushes, rollers, tray, etc.). It will still turn out cheaper than ordering suspended or stretch ceilings.
2. During the whitewashing and drying of the ceiling, avoid drafts and direct sunlight, otherwise the result of your work will crumble.
3. Make sure that during whitewashing the solution (paint) is distributed over the ceiling without the formation of drops and sagging.
4. Do not forget about safety precautions - wear protective gloves and goggles, a hat.

Subject to all the rules of whitewashing, the next ceiling repair will be needed in 3-5 years.
