Featuring a hard, dense structure, Calacatta Gold Quartz is non-porous, abrasion-proof and acid-resistant. Thanks to these outstanding attributes, it can be widely applied to interior surfaces including countertops, backsplashes, walls and floors. However, outdoor use is not recommended since the resin in the material lacks UV stability, which may lead to discoloration, fading or surface gloss loss under prolonged sunlight exposure.
