Water-based paint has long been successfulIt is used not only for interior decoration, but also for outdoor works. But in recent years, water-based formulations are experiencing their second birth. They drew the attention of designers. Such paints began to gain popularity rapidly, replacing various paints based on harmful solvents.
Almost disappeared unsafe oil paint,as well as nitro-enamels, which were often used in our country during the Soviet era. Water-emulsion paint for walls and ceilings is a composition with embedded (but undissolved) in water fine polymer particles, additives, fillers and pigments. After applying the paint on the wall (or ceiling) and further evaporation of water (in other words, after drying the composition), a solid and dense polymer film is formed that firmly adheres to the base.
Water-based paint for walls and ceilingsUniversal: it can be used for finishing surfaces of any type. This is plaster and gypsum board, wood and brick, wallpaper for painting (especially fiberglass) and concrete.
Choosing the right composition on a water basis,it is necessary to take into account that there are several main types of water-based paints designed for finishing different rooms. They have their advantages and disadvantages. In this article we will talk about all the pros and cons of water-based paint for walls and ceilings, how to choose the right composition, calculate the required amount of this material, and, of course, discuss how to apply the product on the surface.
Water-based formulations are divided into several categories. Let's get acquainted with them in more detail.
This is the most popular and often used speciescoating. Acrylic water-based paint for walls and ceilings is resistant to external influences. This is largely due to the presence of acrylic resins in its composition. In case of contamination, it can be washed. Therefore, it is ideal for finishing living quarters, offices, etc.
Features of acrylic paints:
It is the presence of silicone resins that makes thesecompositions are expensive. They can be used to apply to any mineral coatings. The main advantage of this paint is its elasticity: it paints cracks up to two millimeters. Silicone paints are vapor-permeable, and, not least, microbes do not multiply on such a coating.
All this makes it possible to use siliconecompositions in rooms where the humidity is high enough: showers, bathrooms, kitchens, cellars, etc. Due to the filling of roughness and roughness this paint is resistant to temperature and mechanical influences, humidity. It can be applied directly to the plaster without priming the surface in advance.
It is a mixture consisting of an aqueous solution, a liquidglass and colored pigments. Its main advantages include the absence of a surface film, which is replaced by strong chemical-physical bonds. They are very resistant to mechanical and atmospheric influences. Manufacturers of silicate paints guarantee a long service life of these compounds - about twenty years. Such paints are excellent for exterior finishing of open terraces and facades of buildings.
This paint is very popular because of the quite affordable price and at the same high quality. It is produced on the basis of PVA and is intended for interior finishing works.
Benefits:
Mineral water-based paint for walls andceilings in its basis has cement and slaked lime and is used for painting concrete and brick surfaces. The disadvantage of these compounds is a short service life, so lately they have lost their popularity.
If you need a surface that does notis exposed to moisture, you will need a water-based paint for walls, washable ceilings. To obtain this effect, latex is added to the paints. As a result, it can withstand more than five thousand wet cleanings, while ordinary paints can only be wiped occasionally. Therefore, it is suitable for painting ceilings and walls in the kitchen, bathroom. This is a subtype of acrylic paints referred to the average price category.
The advantage of these compounds is not onlyexcellent water-repellent properties, but also the ability to cover fairly large cracks (two layers of paint easily cover the cracks to one millimeter), so before the application does not require thorough preparation with putty.
Today, washable water-based paint for ceilings and walls of the following brands is popular:
Water-based paint for walls and ceilings differs in another indicator - the degree of gloss. To date, manufacturers offer:
Glossy and semi-gloss paints differgreater resistance to abrasion than matte and deeply matte. Paints with a glossy effect can be washed much more often. This is because the surface of such a paint is perfectly smooth and smooth. Cleaning with a damp cloth practically does not change its texture at the micro level, while the matte paint can be quickly wiped, resulting in unsightly glossy spots on the surface. In this case, the surface will have to be repainted.
Before purchasing a water-based paint, it is necessary to study its characteristics: composition, consumption, viscosity, drying time, specific gravity, storage conditions, shelf life.
Viscosity
An important indicator that should be enoughhigh. It determines the degree of dilution of the composition with water. When applied with a brush, this value ranges from 40 to 45 c, when using a spray gun - from 20 to 25 c.
Consumption
It is 150 grams per square meter,250 grams with a double-ply coating. Often manufacturers unintentionally mislead customers, indicating that their water-based paint for walls and ceilings consumption is 110-140 grams per square meter. Such indicators correspond to ideal conditions - a well plastered, completely smooth wall, covered with a thin layer of paint. In reality, consumption, as a rule, depends on the material of the surface being treated, its roughness, absorbency and painting method. For example, the application of a roller is much more economical than with a brushYu.
Drying time
This indicator depends on the humidity and air temperature. The optimum humidity is 65%, the temperature is +20 ° C. Drying time varies from 2 to 24 hours.
Shelf life
Most manufacturers specify the termstorage of their products 24 months from the date of manufacture. In this case, it is necessary to observe the storage conditions: to provide a place protected from heat and not to allow freezing.
One of the indicators of the quality indicators of the formulationson a water basis - their cost. If we consider that 90% of the components and materials used to produce acrylic and waterborne paints are imported to our country from Europe, then the price of one liter of paint can not cost less than 70 rubles. A significant reduction in this cost can be caused by a significant decline in product quality.
There is another indicator of quality - the weight of the paint.Its average density varies from 1.35 to 1.5 kilograms per liter, so a ten-liter bucket should not weigh less than fifteen kilograms. Water-emulsion paint for walls and ceilings should not be purchased in the market, especially in winter, in unheated rooms - when freezing and further defrosting the paint lose its properties.
It is important to choose the right, well-knowna proven manufacturer of water-based paints. Today, Dulux (Great Britain) is the undisputed leader in our market, the water-emulsion paint for Tikkurila walls and ceilings (Finland) has excellent technical characteristics and high quality, Dufa (Germany) paints are equally popular, good quality, but high prices have compositions Johnstone's (Great Britain). From domestic products, we recommend that you pay attention to the "Admiral" and "Eurolux" (Russia).
With the painting of the walls, as a rule, no problemsthere is, but the finish of the ceiling - this is a more complex process in terms of technology. Before you start, you need to prepare the surface - remove the remains of the old coating, polish and align. After this work, the paint consumption will be significantly reduced.
Primer can be and water-based paint, diluted 30-40% with water, but it is better to use a high-quality primer, for your type of surface.
Colored water-based paint for walls andceilings needs to be pre-tested to understand what its color really is. Apply a thin layer of a small amount of paint on the wall and wait until it dries. As a rule, it turns out that the color is several tones lighter than in a bucket.
Painting walls and ceilings with water-based paintstarts from the far corner of the room from the window, after that it is necessary to paint the remaining corners and joints of the ceiling and walls: on the perimeter of the ceiling a strip about five centimeters wide is applied. After that, a roller or a spray gun comes into operation.
In order to be uniform, it is better to applytwo or even three thin layers, rather than one too thick. It is important to know that the paint layers must be applied perpendicular to each other. Each successive layer is applied after the final drying. The last layer should be applied parallel to the light rays, from the window. Thanks to this little trick, errors and small irregularities will be hardly noticeable.
To completely eliminate the problems witherrors, use textured glass pane. The woven textured surface perfectly masks all errors in coloring. Painting the walls, the ceiling with water-based paint is not difficult, this time it takes a little work and at the same time you can create an original interior.
