If after cleaning the old whitewash from the ceiling were dirt: mold, streaks, rust or grease stains - they must also be removed, so that later they do not protrude through the latest.
Rust streaks and wash off with warm water, then place pollution should be treated with copper sulfate solution (1 liter of water take 50-100 g vitriol).
To remove grease stains, a solutionsoda ash. To spot you need to make a cloth dampened with a solution, and hold it until the disappearance of the spot. Then place contamination should be thoroughly rinsed with water.
Traces of mold wash with warm soapy water and treated surface anti-fungal drug. It can also be added to the solution for putty and primers.
Smooth surface required for high-quality repair of the ceiling. We can not expect that whitewash the ceiling will help to mask defects on the contrary, it will only accentuate the uneven surface.
If the irregularities are large, ceiling plaster and pre-sanded. Small surface defects can be eliminated by using fillers and primers.
For ceilings more suitable adhesive putty. To prepare it, you need to mix 2 parts plaster, 1 - chalk and 2 - wood glue. For a mass of liquid adhesive may be pre-mixed with water: 1 liter of water is necessary to add 50 g of glue. The filler is applied by hand with a spatula
After drying, the ceiling is primed. First, a primer must be applied with a brush on hard to reach places and corners of the room, and then the rest of the primed surface with a roller or spray gun.
To learn more about the intricacies of performing putty and primers can be, watching the video:
To whitewash can be used water-based paints, lime or chalk.
Water-based paints are silicate, latex, silicone oracrylic. These inks provide rich white color and applied to the well surface. When choosing colors should pay attention to its coating properties - ability to cover paint the background on which it is applied. The higher the score, the fewer coats of paint has to be applied to obtain a uniformly colored surface, and the lower the probability that it will be visible through all sorts of blemishes or defects of the ceiling.
For rooms with high humidity are choosing silicone water-based paints: water-resistant or washable.
Paints of various parties may differ in tone, so they buy with a small margin.
a piece of chalk for whitewash can be purchased in powder form or in the form ofpaste. Cretaceous paste - a suspension of finely divided chalk, stabilizers and anti-fungal additives. It allows you to get better and more durable finish. In addition, prepare a solution of chalk paste easier than dry chalk: it simply diluted with water.
Instead of the usual quicklime exhaustTo whitewash the ceiling and walls can be usedspecial decorative structured lime. Its application allows you to get the original textured surface. If such a whitewash lacquering, you can simulate the surface of the frescoes.
If you're tired of the ceiling white, with solutions for whitewashing can add pigments. It can be resistant to an alkaline environment minium, vermilion, ocher, ultramarine or finished pigment pastes.
To paint is better to choose the second half of the day. In this case, the first layer of paint for night time to dry out, and in the morning you can safely proceed to the second layer.
To paint need a little brush, cell paint, roller with telescopic handle.
The paint is poured into the cuvette, thoroughly mixed, diluted with water, if instructed.
First paint the corners and hard to reach places witha brush. The rest of the surface stained with paint roller, since the use of the brush may remain traces of brush strokes. The roller must be chosen medium nap, 20-25 cm long.
The color should start from the window. Usually enough for painting ceilings applying two coats of paint: the first layer should be oriented parallel to the direction of sunlight, and the second - at right angles.
Movement of the roller must be W-shaped, forIn order that the surface had no streaks. When roll over the paint, walk them again on freshly painted surfaces - this will remove the remaining paint.
Video dedicated to the use of water-based paints for painting the ceiling:
If you use a chalk paste, mix it with water in a ratio of 1 to 4. In order to whitewash the best kept and was more durable, instead of water, use a 1.5% CMC glue solution (aqueous).
To prepare the solution for whitewash from drychalk, need 5 liters of hot water (40-50 ° C) mix with 30 grams of wood glue, then add 3 kg sifted chalk. You can cook and such a solution: 3-4 liters of water, 60 grams of soap, 90 g glue and 2,5 kg of chalk. Whitewashing, made this solution has a greater adhesion to the surface.
For the preparation of slaked lime mortarlime first thoroughly mixed with sifted sand and then water is added. To improve the surface quality and performance properties underlayer can prepare the following composition: 3.2 kg of slaked lime, 50-100 g of salt, 7.9 liters of water.
Chalk and limestone solutions for whitewashthoroughly stirred until complete disappearance of clots and filtered through a sieve, a loose cloth or several layers of cheesecloth. This allows to remove debris and to make a homogeneous solution.
Chalk whitewash and mortar can bea paint brush, special brush - "maklovitsy" or a paint roller. for whitewash brush should be soaked for several hours in the water, so that during the operation, it does not fall out bristles. Roller is necessary to choose a medium bristle brush. When whitewashing large rooms can also use a pneumatic spray gun.
Before use, checkthe degree of density of the solution. You can use a wooden stick: dip it in the prepared solution and make sure it runs. If the stick is uniformly colored, the solution flows a continuous stream - this is the optimal density for whitewash.
In the room where there is whitewashing the ceiling should not be a draft, since the movement of air causes premature drying of the solution and the formation of traces of brush or roller.
Principles chalk whitewash and mortarIt is the same as when using water-based paints: Belim brush angles, starting from the window to put the 2 layer solution - along and across the direction of light. Before applying the next layer, be sure to check the full drying of the previous - at room temperature for 3-4 hours whitewash dries.
