Resistance to contamination.

Low abrasion, high strength. Paints must withstand mechanical impacts and contact with objects without critical consequences.
Light resistance. It is assumed that the paint will be affected not only by ultraviolet rays, which destroy intermolecular bonds (in this case, under the influence of minor loads, the paint cracks and peels off), but also by infrared rays, which change the original color and contribute to the fading of the paint. The mineral dyes used prevent these effects.

Good vapor permeability. The paint layer should luxembourg mobile database seal the base surface, not preventing the release of excess moisture, otherwise it accumulates between them, and during freeze-thaw cycles, causing the destruction of paint and concrete. It is better to avoid painting the base with oil paints, which create a hermetic layer after drying.
Of course, the criterion applies to the paint itself, but it still relates more to the quality of surface preparation. Smooth surfaces accumulate less dirt - a breeding ground for vegetation, they are easier to sweep and wash, and the base is the lower part of the house, where most of the dust settles.
The time it takes for the surface to dry to the touch and to fully gain strength. Atmospheric precipitation has a detrimental effect on the unhardened film, so time plays a key role.
Moderate consumption. This is an important property for all paints, but it is especially relevant for concrete surfaces, since these are usually large areas, and high-quality painting of the surface involves at least two stages.
