Whitewash the ceiling with his hands — a difficult task for whoever does it first and has no relevant experience. But, adhering to the tips and instructions outlined below, you can perform this job quickly and efficiently.
How to prepare the ceiling ↑
Proper preparation is the key to successful execution of work: the whitewash will then lie more evenly, will not flake or peel off after some time from the ceiling, the surface will appear stains from old dirt. Ceiling preparation takes place in several stages: cleaning old paint, removing contaminants, and the alignment of the ceiling.
How to remove from the ceiling of whitewash or paint ↑
The old whitewash and paint need to be uninstalled. For starters, determine which material was used. Swipe your finger across the ceiling: the chalk will leave a finger on the white trail, lime whitewash leaves.
Chalk can be removed in three ways:
- The most dirty way «dry». It is to remove with a scraper and attached to it a collection.
- «Wet» the method consists in washing the ceiling with water. The surface is moistened by spray, stiff brush, paint roller or a simple cloth (like a wash away the chalk from the ceiling). After the surface is melted, whitewash scraped with a scraper or spatula. If they were prepared based on the adhesive, then wetting them using a weak solution of vinegar. After cleaning, the surface should be washed with soapy water or salty solution.
- The oldest and most pure method of removing the chalk whitewash from the ceiling — the use of paste. The ceiling surface is uniformly coated with paste, and after drying, remove it with the old plaster using a scraper or spatula.
To remove lime wash from the ceiling a bit harder than chalk. It should be dilute with hot water, and after soaking to remove with a scraper.
Removing paint from ceiling — the most difficult process, but it is necessary, as the whitewash is poorly placed on the paint. If the paint layer is thick, it is removed using a Hairdryer. A thin layer can be removed using a grinder with flap disc (dirty, but cheap way) or by using a special composition — shredder paint.

How to remove contamination ↑
If after cleaning off the old whitewash on the ceiling were pollution: mold, stains, rust or grease stains — they also must be removed so that they are not subsequently ran through fresh.
Rust and stains wash off with warm water, after which the contaminated area should be treated with a copper sulfate solution (1 liter of water take 50-100 g of sulfate).
For severe stains, use a solution of soda ash. To the spot you need to put a cloth soaked with solution, and keep it until the disappearance of the spots. Then the contaminated area should be thoroughly rinsed with water.
Traces of mold wash in warm soapy water and the surface treated with an antifungal drug. You must also add it to the solution for putty and primer.
How to align a ceiling to whitewash ↑
Smooth surface is mandatory for high-quality repair of ceiling. You can’t count on the whitewash on the ceiling will help to mask the defects, on the contrary, it will only emphasize the uneven surface.
If the irregularities are large, the ceiling is pre-plastered and sand. Minor surface defects can be remedied with filler and primer.
For ceilings better suited adhesive putty. To prepare it, mix 2 parts plaster, 1 Mela and 2 wood glue. For more fluid mass, the adhesive can be pre-mixed with water: 1 l of water add 50 grams of glue. Sealer applied by hand with a spatula
After drying, the ceiling primed. First, the primer should be applied with a brush on hard to reach places and corners of the room, then primed the rest of the surface using a roller or spray gun.

The choice of materials for whitewashing ceilings ↑
To wash, you can apply water-based paint, lime or chalk.
Latex paint there are silica, latex, silicone or acrylic. These paints give a solid white color and well applied to the surface. When choosing paint you need to pay attention to its coverage — the ability of paint to cover the background against which it is applied. The higher the number, the smaller the number of layers of paint have to be applied to obtain a uniformly colored surface, and the lower the probability that it will be visible through different kind of stains or defects in the ceiling.
For rooms with high humidity choose the silicone water-based emulsion paints: washable or waterproof.
Paint from different batches can vary in tone, so they buy with a small margin.
Mel cutters can be purchased in powdered or paste form. The chalk paste is a suspension of finely dispersed chalk, stabilizers, and anti-fungal additives. It allows to obtain better and more durable finish. In addition, to prepare a solution of chalky paste is easier than from dry chalk: it simply dilute with water.
Instead of the conventional slaked lime, to wash the ceiling and walls you can use special decorative structured lime. Its application allows to get the original textured surface. If such a whitewash lacquering, it is possible to simulate the surface of the frescoes.
If you are tired of the ceiling is white, the solutions for whitewashing, you can add pigments. It can be resistant to the alkaline environment of the red lead, cinnabar, ochre, ultramarine, or prepared pigment paste.

The use of water-based paints ↑
For painting it is better to choose the afternoon. In this case, the first layer of paint the night will have time to dry and in the morning you can proceed to applying the second layer.
For painting you will need a small brush, pan for the paint roller with telescopic handle.
The paint is poured into the cuvette, thoroughly mixed, diluted with water, if indicated in the instructions.
First paint the corners and hard to reach areas with a brush. The remaining surface is painted with a paint roller, since the brush can remain traces of the brush strokes. The cushion should choose medium NAP length 20-25 cm.
Painting should begin from the window. Usually for painting ceilings is applying 2 layers of paint: the first layer should be oriented parallel to the direction of sunlight, the second perpendicular to the.
Movement of a roller must be W-shaped, in order that on the surface there was no band. When the roller runs out of paint, walk them again on the freshly painted surface — this will remove paint residues.

Preparation of the chalk and limestone solutions for whitewashing ↑
If you use a chalky paste, mix it with water in a ratio of 1 to 4. To whitewash better hold and more durable, instead of water, use 1.5% solution of glue KMTS (water).
To prepare a solution to wash of dry chalk, you need 5 liters of hot water (40-50 oC) mixed with 30 grams of wood glue, then add 3 kg of the sifted chalk. You can prepare such a solution: 3-4 liters of water, 60 g of soap, 90 g of glue and 2.5 kg of chalk. Whitewash, made this solution, has a greater adhesion to the surface.
For preparation of lime mortar, hydrated lime is first thoroughly mixed with sifted sand and then add water. To improve the surface quality and the performance properties of the paint, you can prepare the following ingredients: 2-3 kg of slaked lime, 50-100 g of salt, 7-9 liters of water.
Chalk and lime mortars to wash thoroughly stirred until complete disappearance of lumps and filtered through a sieve, a loose cloth or several layers of cheesecloth. This allows you to remove foreign matter and make the solution more homogeneous.
Whitewashing the ceiling chalk and lime mortar ↑
Whitewash chalk and limestone solutions can help paint brush, special brush — «ceiling brushes» or paint roller. Brush to wash, soak for several hours in water below while working out of it does not fall out of the bristles. The cushion should choose medium NAP. In whitewash large spaces you can also use a pneumatic atomizer.
Before use, check the degree of density of the solution. You can use a wooden stick: dip it in the prepared solution, and see how it flows. If the stick is evenly colored, the solution flows in a continuous stream — this is the optimal density for whitewashing.
In the room where the whitewash of the ceiling should be free of drafts, because the movement of air causes the premature drying of the solution and the formation of traces of brush or roller.
Principles of whitewash, chalk and lime mortar are the same as when using water-based paints: lime brush angles, starting from the window, apply 2 layers of the solution — along and across the direction of light. Before applying the next layer, make sure it is completely dry previous — at room temperature the whitewash dries in 3-4 hours.
