In terms of importance and importance, the painting of the building (exterior finish) is put on the same level as the thermal insulation of the house. This is due to the fact that in this way the facade of the building is protected from external factors. In addition, its external attractiveness and individuality directly depend on the exterior finish. Therefore, the choice of paints and varnishes should be taken seriously, having familiarized yourself with all their features. In this article, we will describe their properties, subtleties of application and composition, as well as give recommendations for choosing this type of material.
Like most others, facade paint is a homogeneous suspension of pigments in binders. Depending on these two components, the properties, purpose, and scope of paints are determined. In addition, they often contain various fillers, solvents and targeted additives.
Facade paint is divided into two main types: water-soluble andorganic solvents. Until recently, it was paints based on organic solvents that were most popular. This is due to the fact that they can be used at sub-zero temperatures (especially appropriate in our climate), they are waterproof, and can also be used as facade paint on plaster, wood, etc. But, despite all the advantages, they have a significant disadvantage - low environmental performance. Therefore, more and more buyers prefer safe water-based paints.
It is worth mentioning that this type of them is characterized by high quality, cost-effectiveness and long service life. They are divided, depending on the binder, into silicate, silicone, mineral (lime), cement and acrylic facade paints. The latter have become more widespread and used in construction.
The facade paint is applied with a roller, brush or a special spray gun. After the applied composition dries, a porous opaque or film coating is formed that protects the surface from dust, moisture, light, chemical and other external influences.
When choosing paints and varnishes, attention should be paid primarily to decorative properties - color, structure, gloss level, etc. The appearance of the facade of the building will directly depend on this. It is also worth considering performance indicators. These include weather resistance.conditions, exposure to aggressive substances, pollutants, mechanical stress and washing. Particular attention should be paid to the durability and protective performance of the selected material. If there are additional required functionalities, they should also be taken into account. And the last is the price of the material, based on the consumption per square meter.
In addition to the properties that the selected facade paint has, the type of surface, its biological activity and gas permeability are taken into account. It is especially necessary to pay attention to the atmospheric and climatic conditions in which the building is located, and the total amount of moisture entering the walls of the facade.
