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.

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.
