Facade paints for exterior brickwork: selection criteria

We live in the world of information technology. Through advertising, hundreds of companies, including construction supermarkets and shops, seek to convey to customers information about the quality, properties, and uniqueness of the goods they sell. The range of products offered is so great that sometimes it is not easy to make the right selection of components for repair. The current fashion trend is the creation of a unique bright facade of your brick house with the help of paints.

Today, there are a number of materials on sale for exterior finishing works.

Modern paints and varnishes have a number of the following properties:

• complete absence of chemically harmful substances in the composition;
• resistance to mechanical stress and sunlight);
• elasticity of the coating after staining;
• high moisture resistance;
• compatibility with other paints;
• wear resistance;
• very easy to clean from dirt;
• vapor permeability.

For painting both a new house and old buildings, paint on silicate bricks is suitable. It is applied easily, does not form drips, does not splash. At cost, it is much cheaper than other materials, more affordable for a wide range of consumers.

In general, by its characteristics, a brick is a material that is completely ready for long-term use while maintaining its original appearance. However, the building will look familiar and uniform. Paints will give it a completely new, sometimes fabulous appearance.

The main types of paint and varnish coatings for bricks are acrylic, silicone, silicate, enamel paints. They are glossy, semi-matte and matte. Each has its own reflective ability (complete absence in matte, the highest in glossy).

Acrylic coatings are highly resistant to temperature changes, the term of their use is 8-11 years. Facade painted walls are not prone to cracks and wash well. The paint does not peel off when exposed to rain and sun. Acrylic resin is added as a component, so moisture is poorly absorbed.

In most cases it is not recommended to coat a newly erected façade. This rule does not apply to acrylic paints, since they contain a binder that stops alkaline corrosion present in a fresh solution. Therefore, within 30 days after the construction of the building, you can paint it in any color.

Silicone paints and varnishes are distinguished by their durability and drying speed (- 3 hours after painting). They are protected from mold and mildew by a siloxane (resin-based) solution in their composition. In regions with hot climates and high air temperatures, painted facades do not change their appearance when exposed to ultraviolet rays.

Dust contamination on covered buildings is very quickly removed naturally (rainfall). A painted house can last 18-20 years until the next renovation. Various tints are used to change the color of the paint. The main color is white. You can convert it to any.

Silicate paints are subject to changes in air temperature. They tolerate moisture well, have high vapor permeability and fire resistance. Apply in two steps. The first layer dries up in 24 hours. The second in 8-11 hours.

Enamel coatings are fire hazardous and toxic. They contain varnish. However, these paints are very moisture resistant, durable and corrosion resistant. Drying period is 6-20 hours.

A special mineral paint for brick was created on the basis of cement. It is intended for previously painted facades that are difficult to restore. The degree of water resistance and vapor permeability of such a paint and varnish material is very high. The color of a brick house will not change for 10 years after the walls are treated with such paint.

Oil paints are used much less often. Most often, they are used to paint Russian stoves installed in summer kitchens (temporary huts). It is very convenient to apply beautiful artistic ornaments and drawings using this paint and varnish material.

The best option for staining are multicolored latex acrylic paints (Belinka, Sicily, Acrylatil, Husky, Mikrel and others). Each of them has its own unique characteristics.

Sicily paint is a silicone-modified and alkali-resistant, self-cleaning material. Used for facades of houses located in dusty areas.

If the building was built a long time ago, then white salt spots may form on the surface of the walls. Latex paint manufacturers have developed adhesives capable of forming a film that prevents such deposits from forming on brick walls. To prevent the process of accumulation of white layers, you should find the reasons for their occurrence.

It is necessary to carefully check the surfaces for the presence of condensation, with the help of a sealant (cement), eliminate the places where moisture penetration from the outside is observed. All cracks and irregularities must be repaired. This is followed by the plastering process, after which the facade walls are given time to dry. Then processing (grouting and smoothing of the seams) is carried out with a metal brush.

The primer can be purchased ready-made or made by yourself.

Ready-made are of the following types:

• Acrylic - Works best for latex paint.
• Silicate - has good air permeability. Resistant to precipitation.
• Epoxy - provides surface waterproofing and adhesion.

To make your own mortar for priming brick walls, you need to take the following components:

• copper sulfate -1 part;
• laundry soap - 2 parts;
• wood glue (bone) -5 parts.

Then take a bucket of water and bring it to a boil. Laundry soap is crushed by rubbing it on a kitchen grater. Pour the resulting soap crumbs into boiling water, stirring until dissolved. Joiner's glue and vitriol are added to the solution.

After that, the heat is reduced and the mass is left to boil for half an hour. After the lapse of time, the container with the mixture is removed from the heat, cooled slightly and filtered (warm) through a sieve. The solution is ready. It is applied like any primer with a brush, roller or special painting equipment.

The whole preparatory process ends here.

Painting a silicate brick facade itself is a lengthy, but completely uncomplicated procedure.

You need to choose a paint that meets all the requirements, the main of which is vapor permeability. After painting, the house should become saturated, not having lost the ability to "breathe". Material consumption is also an important point. The more paint is used up, the denser layer it will lie, hide all the irregularities and imperfections on the wall. Do not forget about the color after drying. As a rule, the surface of the walls will be slightly darker than the color of the original dye used to paint them.

Before starting the work itself, it is imperative to cover parts of the house with polyethylene, which do not need to be painted. These are entrance doors, windows, basement. You will also need scaffolding or high stairs, scaffolding.

It is best to paint the entire area in one day, because even with careful selection on the next day, it is very difficult to get a completely identical color scheme. The walls painted in different periods have a slightly noticeable, but different shade. It is recommended to paint first with a brush in the areas of joints of all bricks, and after drying it again with a roller, dipping it into a bath. Movements are made in different directions (both horizontally and vertically). It is important to apply the paint evenly. The first layer is applied with a brush. It makes it possible to get close to the small indentations between the bricks. Then the surfaces are allowed to dry. The drying time for each paint is different and is indicated by the manufacturer on the packaging (can). The second layer is applied with a roller or spray gun. In order to carry out work using a spray gun, a little skill is required.

Usually, windows or cornices are highlighted in richer shades for contrast. If the house has two or three floors, then it is acceptable to use different colors for painting each level.

Work is always carried out in sunny weather. The start and end date of the entire painting process is determined by the owner of the house independently.

Step by step, the dwelling will be transformed, it will acquire a completely new, color-saturated appearance, which will delight the eye for many years. Add a little imagination, imagination and effort and it will pay off handsomely!
