Existing stone, tile and grout must be totally clean, dry and chemical free.

Coverage:
Coverage can vary dramatically depending on the degree of porosity, but is normally 5 to 15 m2 / Lt per coat for open structure, highly porous substrates and 20 to 30 m2 / Lt per coat for dense, less porous substrates. The coverage for the 2nd and 3rd coats is dramatically greater.
