Performance characteristics:
- Water vapor permeability – the possibility of transmission of a couple, the higher the figure, the less likely condensation, which adversely affects the painted base.
- Weathering – resistance to adverse environmental conditions.
- The light fastness of the composition – resistance to ultraviolet radiation, the lower the resistance, the faster the colors will lose their brightness. In glossy coatings lightfastness is better than matte.
Specs are:
- Adhesion – the level of adhesion of coating materials to the surface.
- Paint consumption.
- The drying time of the layer.
Principal facade paints ↑

This type of paint is used for painting surfaces made of concrete and brick, and facades that contain in its composition the lime. The basis of this type is a silicate adhesive or liquid glass. The advantages include resistance to ultraviolet light, a variety of damage, pollution, and long service life.

A coat of paint provides protection to the painted facade for more than ten years.
Exterior paint for concrete ↑
For staining concrete surfaces is most often used with latex based acrylic paint. They are able to provide surface protection from temperature fluctuations, contribute to the healing of microcracks, thereby maintaining the structure of the concrete surface over a long period of use.

To create a reliable protective layer which will protect the surface for a period of more than twenty years, these coatings are recommended to apply in two layers.

So, for example, alkyd and oil coatings are able to withstand temperatures up to 80 °C, acrylic, epoxy and some alkyd – up to 120 °C, polyurethane – up to 150 °C, epoxy-bitumen up to 400 °C and paint with the base silicone resin up to 600 °C.
For painting of metal facade can be used oil paint, but she does not withstand long exposure to moisture, so currently its use began to decline.
