Silicate mineral paint

Mineral Paints are mineral based coatings formulated with potassium silicate or sodium silicate, otherwise known as waterglass as the binder, combined with inorganic, alkaline-resistant pigments. They are fully inorganic (containing no organic solvents) and are non-offgassing. Mineral paints petrify, by binding to any silicates within the substrate, forming a micro-crystalline structure and a breathable finish. They are more of a stain, that becomes integral to the substrate, rather than a coating. They are alkaline and therefore inhibit microbiotic growth, and reduce carbonization of cementitious materials.

The majority of non-toxic concrete stains and limestone restoration products are waterglass based. Mineral paints are also used as a non-toxic wood preservative.

The difference between the use of sodium silicate and potassium silicate as a binder is mainly geographic. The western hemisphere mainly produces sodium silicate, where Europe produces potassium silicate

Possible substrates:
*masonry
*stone
*concrete
*lime plasters
*earthen plasters

Applications:
*environmentally friendly, non-toxic applications
*high durability, especially on masonry products, and lightfast
*breathable finish
*Acid rain resistance
*antifungal properties
*reduces carbonization of cement based materials
