Pumice fine powder is being used increasingly in the paint and coatings industry, this is an alternative to traditional fillers due to its low density and unique particle morphology. Pumice powder provides Interior paints with Burnish resistance, flatting, low sheen and low film porosity. The use of Pumice in exterior paints and stains provides outstanding tint retention, mildew resistance acid resistant giving frost free surface and increased cracking and flaking resistance. Pumice powder can also be mixed into emulsion paints to change their colour or simply mixed with water to use as a wash. The hardness, chemical resistance, and abrasive qualities of pumice powder, also make it deal for floor and deck coatings. Pool deck coatings have been successfully formulated with pumice powder and in some cases pumice grains for a number of years.
