How to whitewash the ceiling and walls correctly?

Among the modern methods and possibilities of decorating the ceiling and walls, whitewashing is still becoming relevant today. Whitewashed ceilings are not only easy, but also inexpensive. In addition, sometimes it is possible to re-whitewash the old layer, and refresh the appearance of the room. But this can be done if the first coat was applied correctly..

What it is?

There are several methods for making whitewash. The most popular is chalk, it is a simple and affordable composition for whitening indoor surfaces. The second most popular material can be called lime, this is due to the fact that walls and ceilings treated with it can resist damage by fungus and mold. Another equally popular material is a composition called fluff. This is a powder that has a white color and has passed the quenching stage after liquid and fixing agents have been added to it..

Modern production produces lime:

  • slaked, which is supplied to points of sale under the guise of paste or powder;
  • quicklime, sold as pellets or large lumps.

Before proceeding with the repair, you need to know what technical characteristics are inherent in whitewashing, what is its application. To begin with, we note that a dry mixture for whitewashing is used almost everywhere. A two-component emulsion made from it is suitable for an apartment, for manual treatment of walls in a bathroom and even for decorating the facade of a house from the outside.

In order to whitewash the walls and ceiling, they use exclusively slaked lime, but first you need to prepare it.

This will require:

  • lime and water in a 1: 1 ratio;
  • a metal container, it must be absolutely clean, free from damage and rust;
  • lid;
  • a wooden stick or spatula to stir the mortar.

After lime is mixed with water, the boiling process begins, the solution heats up to 130 degrees. The consistency begins to boil and splatter, so it is better to close it with a lid so that the composition does not get on the skin.

It is forbidden to use plastic dishes as a container, since under the influence of temperature it can begin to melt, in addition, it will be extremely inconvenient to stir the composition.

After the composition is covered with a lid, the container must be transferred to a cool place for 3 weeks.. After the specified period, the consistency is taken out and thoroughly mixed, this must be done until all the granules dissolve, and only a white shroud remains. If necessary, water can be added to the finished solution to obtain a homogeneous but opaque composition..

As a result, if you use 1 kg of quicklime, you should get about 10 liters of solution. Most often, during the quenching process, all the granules dissolve, so that there are no further incidents in the work, the solution must be mixed with special care, and before working with whitewashing, it is advisable to strain the consistency through a special sieve.


Today, in order to use plaster, it is enough to dilute it. In addition to determining the volume of material per 1 m2, you also need to know the shelf life of the composition, as well as – how it needs to be diluted, whether it is necessary to wash off the old layer. If we talk about the decorative side, then even a combination of colors can be used here. Colored whitewash is no longer a rarity. So, at the KSOM plant, not only material with chalk or an adhesive base is produced, for them the norm is the production of a wide variety of compositions.

The whitewash is designed to give the walls and ceiling a beautiful look.. It makes it possible to freshen up the interior of the room. The peculiarity of using this material is that the work surface must be properly prepared..

To whiten a surface, pay attention to the following points:

  • what whitewash was used previously;
  • how firmly the old coating holds;
  • is there any dirt on the surface;
  • whether there are cracks or chips on the old layer;
  • functionality of the premises being repaired;
  • whether the tenants are allergic to the presented material.

Before starting work, you need to decide whether there is a need to remove the old layer, or it makes it possible to work on the surface without removing it.

Pay attention to the condition of the old layer. If in some places it began to crumble or lag behind the surface of the walls or ceiling, it is impossible to whitewash the ceiling on this layer, it will need to be removed. In the event that the old coating begins to peel off, it is removed, and the irregularities that form in these places must be covered with a putty, and putty is also suitable.

How to apply?

Layering of whitewash is not as difficult as it might seem at first glance..

In the process of work, you can use:

  • brush;
  • roller;
  • spray gun;
  • special vacuum cleaner that blows out air.

The last two options can speed up the workflow, but they are not suitable for use in an apartment or house, since the spray will spread over the entire area of ​​the room, which is inconvenient. But the brush and roller will become more convenient solutions..

Note that the type of final work will depend on the quality of the brush and roller.. For this purpose, it is better to purchase brushes designed specifically for whitewashing, they are made of natural bristles, and the thickness of the working bristles should be from 15 to 25 mm.

Before using the brush, you need to place it in warm water for several hours, thanks to this action, the handle of the tool will begin to swell and fix the bristles, during the work the fibers will not remain on the surface. After the repair is over, the brush can be rinsed under running water..

As for the rollers, then work with them will be carried out much faster. There are no special requirements for their purchase, so they do not need a separate description. It will be useful for them to purchase a special pallet, this will ensure accurate work. The quality of the work done by the roller will be much better.

If you have a brush or sponge, this will certainly not ruin the work, but the process will be slow, especially when using a spackle. You can use a vacuum cleaner, but in this case it is very difficult to make sure that the rest of the area does not get dirty and the decorative plaster does not scatter. Experts recommend using the KRDP-3 apparatus. This is a hand-held paint sprayer that will help you tackle any complex finishing job..

How to whiten with your own hands?

It is very simple to whitewash the ceiling, the main thing is to do everything correctly and logically so as not to miss important points.

The whitewashing process consists of the following steps:

  • we determine what type of whitewash has already been applied to the surface, for this we run our fingers over the material, if there are white traces – chalky, if not – lime;
  • we decide whether to remove the old coating or not;
  • we check how firmly the old whitewash holds;
  • if there are poorly attached layers, remove;

  • we close up all the existing irregularities, cracks and cracks;
  • after everything is dry, using pumice or sandpaper, we wipe all layers;

  • remove all dirt spots;
  • we process the surface with a deep penetration primer;

  • based on the old type of whitewash, choose a new one;
  • preparing the mixture;
  • apply the solution to the ceiling or walls.

If the process is carried out strictly according to the indicated stages, then the result will be clean, neat and beautiful..


Whitewashing with chalk or lime is an environmentally friendly material used for renovations. But it should be noted that chalk often crumbles, and many are allergic to lime. Therefore, a water emulsion can be used as a whitewash. It is able to give any surface a beautiful appearance, however, it should be remembered that the treated area will not “breathe”.

When using chalk whitewash, you will need to prepare 3 kg of chalk, 5 liters of warm water and 30 g of carpentry glue. All this is mixed, blue is added to the solution, it is thanks to it that the ceiling or wall will acquire a snow-white shade. The amount of blue used depends on the area to be treated. If the above proportion is used, then 15 g of the substance is enough.

More convenient for whitewashing surfaces will be water-based paint, which is sold ready-made..

Try not to forget that the consumption of this material is very high, and it is very important to immediately purchase a sufficient amount of it so that later, by purchasing additional material, you do not get a difference in color..

This treatment will be ideal for walls and ceilings in the bathroom, since the painted surface can be washed..

As for the rest of the rooms, it is necessary to apply whitewash here in several layers., it is very important that each subsequent layer overlaps the previous one. Pay attention to the application technique, the first layer is applied perpendicular to the incoming sunlight, the second – in parallel. In addition, each subsequent coat should only be applied after the previous one is completely dry. If the technology is broken, bubbles will start to appear.

Lime is popular for its bactericidal properties. It is able to close all cracks and stay on the surface for a long time, while the price policy of the material is small.

If we take into account the negative properties, then the biggest disadvantage is the smell that begins to appear after the solution is made. One should not forget about safety measures, if you use lime without gloves, then it can corrode the skin..

Despite the presence of an unpleasant odor, lime whitewash is used very often, as it can eliminate the fungus.. In addition, it is precisely such a whitewash that is recommended for use in rooms with a high humidity indicator, for example, in a bathroom. Lime whitewashing is also ideal because it can be used to hide cracks and small crevices..


Before getting started, we recommend that you read some tips.

First, secure yourself:

  • the furniture in the room must be taken out, if this is not possible, it must be covered;
  • use gloves and special glasses;
  • put on a respirator and headgear if necessary;
  • if you are afraid to stain the wall when processing the ceiling or vice versa, separate them from each other with masking tape at the joints;
  • the tile covering does not need to be protected, it can be easily washed off with water.

Experts do not recommend making a new coating over the old one. First of all, this concerns the further quality, and secondly, the appearance. If there were stains or dirt on the old ceiling or walls, then everything will be visible on the new whitewash. Therefore, before starting work, make sure that the base is perfect..

Surface preparation tips:

  • remove all cobwebs with a damp cloth;
  • start removing more complex dirt;
  • remove mold with a special product;
  • if there is rust, wipe it off with a damp cloth and treat with copper sulfate;
  • for oily stains, you can use ordinary soda diluted in water, after the stain is removed, the surface is washed again with water.

          Do not disregard even small yellow spots that seem invisible at first glance. The fact is that under the influence of a new layer of whitewash, they will become brighter and will be very striking. In order to remove the stubborn stain and make the wall white, you can use whiteness with water, as well as an ordinary rag..
