Silicate mineral paint

From Wikipedia, the free encyclopedia

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
