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
