The most common way to design the ceiling is its whitewashing or painting. And the most used paint - water level. At first glance, the ceiling of the ceiling in the first glance seems simple, but there is a lot of subtleties, non-burning of which leads to the appearance of spots or strips. How to avoid the appearance of such a trouble, let's tell on.
Preparation for painting
In order for the self-painting of the ceiling of water-level paint to be high-quality and uniformly needed preliminary preparation of the ceiling. It is possible to achieve uniform staining only on a smooth covered surface. Therefore, before starting work, it is necessary to clean the ceiling from any previous coating (with the exception of water-emulsion, which rests very well).How to remove bliss
If you have the ceiling on the ceiling - chalk or lime - you need to moisten the ceiling with water, and remove the coating with a spatula. Read everything to concrete. It is necessary to delete even the smallest fragments. Sometimes a spatula of scruffing small sections is very uncomfortable, it is easier to make it a wet rag.
Burning easier to remove wetting her water
In any case, after removing the blots, the ceiling must be washed with water with a detergent. After complete drying - to be primed and placed with plaster or cement (preferably white) putty to an even state, which is also called "under the egg".
How to remove old water emulsion
If the ceiling has already been painted with a water-free, just remove it will not work. The procedure depends on how paint holds on the ceiling. If she just changed the color and you need to refresh the ceiling, no swings, cracks and other similar problems, you can do with low blood. First - remove dust (with water rag), dried, then process to. After drying the soil, you can paint. But once again we pay attention - this order of action is used only if the water-emulsion is kept well and there are no defects.
Consider waterproof water emulsion from the ceiling
If there are cracks on the surface of the water-emulsion, swollen, it should be considered. The method is two - dry and wet. Dry is to consider emery paper (manually or using ABM), wet - flush. This method has to be used for paint, which is not afraid of water. But it is very difficult to consider such paint. If the water-emulsion paint is well held, no tricks help, but the surface defects have and need a putty, take sandpaper with a large grain and make the surface rough. After that, you can put off. Next - on technology: soil and after painting.
Wash off the water-colored ceiling twice abundantly wasting hot water. Water should be almost boiling water - about 70 ° C. Watch a part of the ceiling Wait 10 minutes, then wash the same section of hot water again. After five minutes, you can remove the paint with a spatula.

Removal of old paint - long process
You can repeat a similar procedure several times, gradually removing the lagging paint from the ceiling. Small residues can be cleaned with a skin, and then rinse the ceiling, dry and prejudice. On the primer, you can already put shnot, to bulk, leveling flaws.
Types of waterfront paint
The water-based paint is an emulsion based on water, which contains particles of polymers undisputed in water. Also, the composition includes pigments and various additives that change the characteristics of the final product. After applying paint, active evaporation of water occurs and a thin polymer film remains on the surface.
Painting the ceiling of water-level paint begins with the choice of composition. They use four types of polymers in them:
- Acrylic. The aqueous emulsion based on acrylic resins allows to obtain a flat surface, it has good shelterness, hides small surface defects, up to slots up to 1 mm wide. Its disadvantage is a high price, but it is easier to work with her. In the pure form, acrylic compositions are hygroscopic and can only be used for dry rooms, but they do not interfere with the passage of steam. Latex is added to the creation of a waterproof film to acrylic water-free. The same additive increases the elasticity of the dried film. Such formulations can be used in wet rooms.
Acrylic Base Based - Reasonable Choice
- Silicates. The basis of this type of waterfront paints is liquid glass. The coating is obtained resistant to atmospheric precipitation and does not interfere with the removal of vapors, has a long service life (10 years and more), can be used for outdoor work.
Silicate paint pairspermers
- Minerals - lime or cement. Mineral water disposals have a good grip with any surface, but quickly wash off. In this connection, gradually losing popularity.
Mineral-based water-based paints (lime) are the cheapest
- Silicone. Aquicon-based water emulsions are the last achievement of industry. These compositions are good in that the cracks are "tightening" with a thickness of up to 2 mm. As a result, the surface painted by them, even without excellent training, it turns out even and smooth. The film is obtained dense, but vapor-permeable. Silicone water disposal can be used to paint the ceiling in bathrooms and other wet rooms. Lack of this type of paint - high price.
Silicone water-free paints can even paint crack
Latex can be added to any of the compositions. Latex water-repellent paint is obtained water-repellent. It is not afraid of moisture, can be used in wet rooms.
Based on the main characteristics of these compositions, you can choose for yourself the best type of waterfront paint. In each case, their properties and "best water-emulsion" are required - every time different.
What kind of primer use
The primer is necessary for better clutch (adhesion) paints with a painted surface. It avoids the appearance of cracks and swirling after drying paint. If the primers are not, it can happen. We will have to consider everything and re-tap. Because the painting of the ceiling of the waterfront paint was high quality, it is necessary to primitive surface.
The base of the primer must coincide with the main paint. Under the acrylic paint, the water emulsion is needed by the same primer, under silicone - based on silicones, etc. Moreover, it is advisable not to save: the quality of this composition depends on how much the water-emulsion in the ceiling is.
Acrylic primer under the same water-emulsion paint
There is an economical way of primer: the main paint is bred by water (1 to 2) and this composition is scratched a couple of times. This is definitely better than nothing, but the primer gives a more reliable clutch.
How to paint the ceiling with a water-emulsion
Each of the water-making paints on the bank has instructions for use. The order of work is described. Some formulations need to simply stir up before work: undisguised polymers can settle at the bottom of the banks. Some formulations require breeding. The amount of water added is also spelled out in the instructions and depends on the method of application. Under the paintopults are designed stronger, with the use of rolling, more dense compositions are required.
Paint bath makes work easier
When diluting water-free water, it is necessary to add it in small portions. Carefully stirring, try on the surface area. If the paint fall smoothly, almost completely paints the base, you can paint.
It is more convenient to pour in a special container with a bath and a ribbed platform. You can use the usual basin and a clean piece of the oilcloth, unsettled nearby. It is not so convenient, but less costly.
What roller choose
The roller for painting the ceiling by water-emulsion is needed with a dense short pile. You need to examine it carefully. The pile must "sit" firmly and in no way should "climb", even if you pull for it. Then inspect how the seam is made. In no case should not stand out. It should be difficult to find it. Best of all, if it is made by male.
Rolls for painting ceiling by water-emulsion
Dedicate the maximum of attention: the quality of painting is the lack of bands on the ceiling - largely depends on how good you picked up the tool. It is more convenient to bleach the ceiling by a water-emulsionist with a stepladder, but from the floor. For this, the roller is planted on a long stalk and fasten well.
How to paint without divorce
In order for the ceiling there is no bands, the painting of the ceiling by water-level paint should end no later than in 20 minutes. The water immediately after applying begins to actively absorbed / evaporate and on the place of the junction of the frishes and the "fresh" color and the stripes appear. Therefore, it is advisable to prepare the room. It is necessary to disable (wrapped) the heating battery, prevent the appearance of drafts. It is also desirable to wash the floor directly before whitewash, even if you work in the afternoon, turn on the lighting, it will better control the quality of the color. After you can proceed to work.
Ready to use the water-emulsion paint is poured into the container, dip in it the roller, then rolled well on the site, achieving a uniform distribution over the entire surface. When the roller will have a monophonic color, begin to paint.
The first tassel is missing the corners. I appline a little paint, take a small roller and rolls it well. Then they begin to paint the main surface. The first layer is applied parallel to the window, the second is perpendicular.
It is necessary to stand so as to look at the stained place at an angle. This will give you the opportunity to see how much paint was distributed, as well as the place where you were already painted, and where - no. Move the systematic, without jumping from one piece to another.
It is more convenient to paint off the floor, and for this, the roller must be attached to the long but light handle
The width is painted at times - a little more roller width. Watering a roller, put it around in the middle of the strip. Quickly roll out the paint in both sides of one wall to another. Do not lose time: you have it enough. On average, the water-freezer dries over 10-20 seconds. I did not have time to put the band nearby - it will be clearly visible the border from which you do not get rid. After distributing more or less evenly paint on the strip, the roller dip in the paint, and again from the middle of the ceiling roll over. At the same time, you never already scratched the band by about 10 cm. All this is in a good pace without stopping and smokers. The edges of the scratched strip should not be filled. In general, this is all the rules.
After applying the first layer of paint, some places may be worse thanks. We must wait for a complete drying, and paint the second time. This should already be enough to obtain a smooth surface. If after the third layer of water-level paint you have bands and divorces on the ceiling, you will have to redo it. It is necessary to align the surface with emery paper, rebuilt and dye again.
Which color
The easiest way to achieve perfect smooth painting when using the "snow-white" paint. All pigments clearly distinguish even small irregularities, because the process of putty the ceiling should be given to maximum attention or use a water-emulsion on an acrylic or silicone basis.
