Facade paints: what is it and what are the types
By and large, facade paints contain binders with suspensions of pigments, fillers and solvents, which give the paints auxiliary operational indicators and characteristics. Like others, this type of paint is divided among themselves into groups. These are, first of all, two main groups:
- organically soluble;
- water soluble.
The first group of paints contains such low toxic and toxic substances that have a dissolving function: white spirit, solvent or xylene. It is these substances, in addition to toxicity, that are also weakly resistant to fire. Among other things, such paints can incorporate a thermoplastic acrylic resin, which perfectly serves to form a film, which is a very important factor for the exterior walls of a house. Due to their toxicity, such paints are bought less often than those belonging to the second group.
Paints belonging to the second group are more popular, and their assortment is wider than organosoluble paints. Subgroups of water-soluble paints are divided by the effective substances contained in them, which perform each function when working with such paints. These are such subgroups of water-soluble facade paints:
- siloxane;
- acrylic;
