Taking advantage of special paints for facades could be a savvy option to protect protect the exterior from environmental impact and prolong the lifespan of the concrete surface. The option is appreciated by engineers: not only they paint facades of buildings, but also utilise this painting method to protect concrete structures from moisture and biological factors. When choosing paint for concrete for the exterior you need to take into consideration their properties, which must be above reproach. Mentioned below are the aspects you should consider when choosing the product.
Moisture. The paint should not pass moisture into the material of the walls.
Fire resistance. In case of fire, the paint should not be ignited and contribute to the spread of fire.
Adhesion to the concrete, an ability of materials to adhere to the surface by means of intermolecular effects. With a low degree of adhesion to concrete paint will peel off and get separated from the concrete surface.
Light resistance. It is the quality of the paint shows its ability to retain the original color when exposed to ultraviolet rays.
Resistance to changes in temperature. This feature of the painting material characterises its ability to resist changes in temperature. The temperature range of outdoor paints for concrete are large enough: from -50° to +50° C. Such companies as Britannia, standing out from the crowd with innovative exterior wall coatings solutions, go even further and offer the products that stand out -65°.
Water vapor permeability. The paint provides a surface layer of the concrete facade, thus allowing the passage formed inside a pair of premises. It should have a zero water absorption and maximum vapor permeability.
Consumption. This aspect stands for the amount of paint needed to paint 1 square meter of the surface. The concept of coverage indicates how thin coat paint should be to make a smooth color transitions from one color to another.
