Silicone paint for the facade - do-it-yourself selection and application rules!

Painting takes one of the first places among the many methods of facade decoration. Due to the special properties of modern paints, the walls are reliably protected from moisture, they are less dirty and look very decorative. Plus, painting is much easier than installing siding or laying tiles.

The choice of coloring compositions is wide, but silicone paint for the facade has the best characteristics, which will be discussed in the article.

Composition and advantages of silicone paint

Silicone facade paint

High moisture resistance of paint provide silicone resins on the basis of which it is produced.

In addition to resins, the composition contains acrylic dispersion, modifying additives, fillers and an aqueous emulsion, therefore the paint is water-soluble. There are no chemically aggressive substances among the components, and when working with paint there is no need to use protective agents.

Protective agents do not need to be used

The benefits of silicone paint include:

  • waterproof;
  • resistance to ultraviolet light and temperature extremes;
  • vapor permeability;
  • high adhesive properties;
  • coating elasticity;
  • resistance to microorganisms;
  • durability ;
  • excellent compatibility with acrylic and mineral paints.

It is suitable for any surfaces, can be applied to old coatings (except varnish and oil), easily cleaned from dirt. The paint has a rather viscous consistency, due to which it does not splash during application and almost does not form sags and drips.

Features of use

Like other types of paints, silicone paints require preparation of the working surface and adherence to temperature conditions during application: not lower than 5 ° C and not higher than 25 ° C.

Paints are applied only at positive temperatures

The presence of dust, dirt, oil traces and a loose coating on the walls will lead to flaking of the paint layer. At the same time, when preparing the facade, it is not necessary to carry out additional treatment with antifungal agents, since the silicone coating does not contribute to the development of mold and mildew. It is enough to apply a regular primer, which will strengthen the plaster layer and reduce the absorption of the paint.

Ceresit facade primers for preparing the facade surface

Another feature of silicone paints is resistance to alkaline substances, which allows them to be applied through 48 hours after plastering the walls.

The vapor-permeable film that forms during the painting process allows the plastered surface to "breathe", but does not let water through from the outside. This significantly reduces the time for finishing the facade.

How to calculate the amount of paint

To determine the required amount of paint for the facade, you need to know the total area of ​​the painted surfaces, the number of layers and the approximate consumption of the composition per 1 square meter. Consumption directly depends on the density of the paint and the porosity of the walls - the greater these indicators, the more composition is consumed per square meter. Manufacturers indicate on the packaging, as a rule, the minimum consumption provided that it is applied to a smooth, dense base. For silicone paint, it varies between 150-600 g / m2.

Silicone paint for the facade - do-it-yourself selection and application rules!

The number of layers also depends on the surface quality and the desired color saturation. Usually facades are painted in 2 layers, this is quite enough to obtain an even deep color. If the substrate has a non-uniform structure, the absorbency of the paint may differ in certain areas, resulting in stains on the facade.To eliminate such defects, a more thorough surface preparation or the application of a third layer of paint is required, which also increases consumption.

Silicone paint for the facade - do-it-yourself selection and application rules!

The more layers of paint, the more consumption

So, to calculate everything correctly, you need to multiply consumption per m2 by the number of layers and multiply by the area of ​​the facade.

For example, let's take the Ceresit paint, the consumption of which is about 0.3 l / m2. The base is cement plaster, the number of paint layers is 2. The area of ​​the facade is 70 m2.

We carry out calculations: 0.

3x2x70 = 42 liters

That is, 42 liters of silicone paint will be needed for the entire facade. Since "Ceresit" paint is packaged in buckets of 15 liters, you should buy 3 buckets. Please note that you will not be able to save money by diluting the composition with water: an excessively liquid paint forms an uneven thin layer through which the base will shine through, and even after applying the second layer, you will not be able to achieve a deep saturated shade. And the quality of the coating will remain rather low.

Thorough preparation of the base, which consists in leveling with plaster mixtures and high-quality priming of the surface, will help to really reduce the consumption.

And if, at the same time, you also choose the color of the paint to match the base, in some cases you can get by with one layer of coating.

Preparatory stage

First, you need to correctly assess the condition of the facade. If it has been painted with oil enamel or coated with varnish impregnations (for example, "wet stone"), the top layer will have to be thoroughly cleaned, regardless of the strength of the coating. To remove the varnish, use special removers or sandblasting. The easiest way to remove oil paint is with a hot air gun and a stiff spatula.

Mechanical method for removing old paint

Acrylic paint does not need to be cleaned, the main thing is that there are no delamination, oil stains on the surface, others pollution.

If the facade was simply plastered, check the integrity of the plaster over the entire area. Areas that began to crumble and crumble should be cleaned with a spatula to a solid base and putty. Cracks more than 2 mm wide are filled with cement-sand mortar. If you plan to paint brickwork, be sure to check the seams, fill the voids with a solution.

Cracks need to be putty

For priming, it is best to use water-based silicone compounds, and it is advisable to buy both the primer and the paint from one manufacturer. For smooth concrete surfaces, one layer of primer is enough, for plastered surfaces 2-3 layers are required.Allow a certain amount of time between coats to allow the primer to dry completely.

Priming the facade significantly improves the adhesion of the new coating to the surface

If the facade has decorative inserts or areas that are not intended for painting, they are sealed around the perimeter with masking tape so that you do not have to wipe off the paint later. The same is done around door and window openings.

When using a spray gun, it is better to cover window panes with foil, thin plywood or at least newspapers.

Paint tinting

Silicone paint for the facade - do-it-yourself selection and application rules!

Shades of colors

Nowadays almost no one paints the facade in White color. Thanks to the huge range of colors, you can choose almost any shade to make your home different from others. Ready-made color paints have a limited range, so many people prefer to tint on their own. Sometimes, as a result of incorrectly selected components or a violation of the mixing technology, the painted walls turn out to be spotty, with unaesthetic stains or blotches.

Also a common problem is the difference in shades when painting large areas, for which the paint has to be tinted in several portions.

To avoid such errors, the following rules must be observed:

  • color and paint must be selected from the same manufacturer. In this case, the base paint should have a reduced content of white pigment, which makes it difficult to color the composition. Manufacturers usually indicate this information in the instructions on buckets of paint;

    Silicone paint for the facade - do-it-yourself selection and application rules!

    Color in plastic packaging

  • the amount of color should not exceed 20% from the total mass of the paint. Excessive content of such pigments leads to a decrease in the covering ability and waterproofness of silicone paint, reduces its service life;
  • when mixing paint, strictly observe the same proportion.

    If you took 10 liters of paint and 1 bottle of color for the first portion, then take exactly the same amount next time. It is impossible to measure "by eye": even some 30-40 g of base paint will affect the final result, and after the wall dries, one area will be lighter than the other. The same applies to the color pigment - just a couple of drops more or less, and you will not be able to get the desired shade.

    Silicone paint for the facade - do-it-yourself selection and application rules!

    It is important to strictly observe the proportions

Tinting is carried out as follows: the desired color from the bottle is poured into a bucket of white paint and mixed with a mixer until the mass is smooth. Mixing by hand is not recommended, as undissolved pigment particles may remain in the paint (especially at the bottom of the bucket and at the bottom of the walls), which, when stained, will leave contrasting blotches and stains on the surface.

Consider the procedure for painting plastered walls using a roller.

Step 1 . First, paint over the corners with a brush, areas around the openings and decorative inserts on the walls. The paint is applied in a thin layer and rubbed well so that it fills the smallest recesses.

Step 2. Next, pour the paint into a paint tray and roll the roller several times so that it is evenly saturated.

The tray will allow you to immediately pick up paint on the roller and roll it out

The first layer of paint is applied in vertical stripes from top to bottom, firmly pressing the roller against surface. Try not to leave unpainted areas or layers of paint.

Step 3 . After the entire facade is painted, you need to wait a while. Despite the fact that it takes from 4 hours to a day to completely dry, silicone paint can be applied with a second layer in 1-2 hours after the first.

The exact intervals between coats are indicated in the instructions, as well as the time for complete drying.

Step 4. Once the walls are dry and the paint will not leave marks on the hand when touched, apply a second coat of paint. Everything is done in the same way as for the first time, only the movements of the roller should not be vertical, but horizontal.

Applying the second layer

After painting the main area of ​​the facade, you can start processing the basement and decorative elements.

All work must be carried out in dry, calm weather, in the temperature range from +5 to 30 degrees. If it rains within 24 hours after painting, it can nullify your efforts, and the work will have to be redone. Although the paint is hydrophobic, it can be easily washed off with water until the coating dries completely.

Smooth, large areas, you need to paint without interruption in work. Leaving the unpainted part the next day, you run the risk of getting areas that differ in color.

In the process of work, the paint must be regularly mixed, since it tends to settle.

Painting wooden facades

Silicone paint is also great for wooden houses. The main condition is that the tree must be completely dry and strong.

Step 1. Using a brush or scraper, remove the old paint, and then carry out a wet cleaning of the surface from dust and dirt.

Step 2. If necessary, strengthen the plank sheathing, replace damaged elements.

Step 3. Apply a primer in 2-3 layers, depending on the porosity of the wood. The joints in the corners and around the openings are especially carefully processed.

Step 4. After drying walls start painting. To do this, it is best to take a wide, medium-bristled paint brush. The paint is applied along the boards, evenly rubbing with a brush over the surface. After the primary treatment of the area, take a break for 1-2 hours, then apply a second layer.

Subject to the technology, such a coating will reliably protect the wooden facade from moisture for 10-15 years without reducing the decorative qualities. Much depends on the wood itself - the stronger the material, the longer the coating will last.

Maintenance of the painted surface

The coating that forms silicone paint, maintenance is absolutely undemanding. Most of the pollution (dust, soot from car exhaust) is washed off by rain, so the facade looks clean almost all the time. If necessary, you can spray the walls with water from a hose, this will be quite enough.

Despite the elasticity and strength of the film, under strong mechanical stress scratches remain on the paint, through which the base shines through. You can eliminate such defects by tint, but the difficulty lies in the fact that the paint remaining after the repair does not last long, and it is not easy to choose the exact same color.

Tint the wall of the house outside

In this case, you need to buy the smallest package of white paint and the appropriate color, and then pour it into a separate capacity 100 g of paint and add 1-2 drops of pigment. Stir thoroughly until smooth, evaluate the result. Add 1 drop of color until the color is the desired shade.

Now apply paint to the wall where it will be least noticeable and wait until dry. Just a couple of strokes are enough, you don't need to paint over much. After 1-1.5 hours, you can compare the colors - if fresh strokes do not stand out against the background of the wall, the ratio is correct, otherwise you should add more dye. Be sure to remember the proportions, because the trial amount may not be enough to paint over all the defects.
