Tile surfaces are protected by Q-Seal, a permanent sealer that is water and stain resistant, protects against abrasion, and features Ultra-Fresh® anti-microbial protection, which inhibits the growth of stain and odor-causing mold and mildew. Q-Seal is factory-applied and never needs re-sealing. Stone or grout sealer inadvertently applied to the surface cannot penetrate or adversely affect Q-Seal. Simply wipe excess sealer off the tile.
Questech warrants that for a period of 12 months from date of purchase Questech tiles will not fail to meet the performance specifications outlined in the Technical Performance Summary (see below), due to manufacturing defects.
