Through the reaction of potassium silicate with aerial oxygen a gel of silicate acid (K2SiO3 + CO2 = SiO2gel + K2CO3) is created, which ties the pigment particles and filling agents in paint substance and reacts with silicate filling agents, which are contained in a brown coat, so called silicatization – the paint is chemically bound to the undercoat.
The silicate paints are currently experiencing rebirth, because it had been found out, that the dispersed stone paints fit only some backcoats, not all of them. This paint unifies excellently the structural differences between old, new and also sanitation plastering. It also enables covering of microcracks in browncoats and creates a unique transition bridge between the old dispersed and the new silicate coating. Its characteristic optical properties render coated surface a natural mineral-dim appearance. If the conditions of silicate paint manufacturing are kept correctly, the coatings are very permanent and the operational lifetime is dependant only on the quality of the brown coat. The connection is highly stable and persistent towards acids. Long operational lifetime of silicate paints applies to all silicate generations to an equal extent.
