No. GS03 Grout & Stone Sealer is a VOC compliant, solvent based formula designed for deep penetration on both polished and porous stone, masonry, grout, and concrete.

 It protects against oil and water based stains while still allowing the surface to breathe. It is non-yellowing, long-lasting, and will not change the appearance of the surface. Overspray that does not penetrate the ceramic tile, porcelain, glass block, stone or grout will dissipate and not leave any hard to remove residue.
