Cast Metal City Scapes by Questech brings beauty to today's home with designs that are aesthetically pleasing yet also highly functional. The tiles will vary naturally from piece to piece. However, they do not vary from lot to lot like ceramic tile, and will always coordinate beautifully together. Tiles that are Cast in Questech can be installed using standard tile setting methods (polymer fortified thin-set, epoxy and mastic). They cut easily with a wet saw or a spiral saw and can be drilled with a high-speed drill. Do not score and snap. To ensure proper bond, high temperature installations might require epoxy adhesive and grout. Examples where epoxy is recommended includes some kitchen cook-tops, fireplace surrounds and steam showers. Please read Questech Cast Stone Installation, Use & Care Instructions for full installation information prior to installing tiles. The surface can be cleaned with any ordinary household cleaner. Harsh chemicals like bleach should be wiped away shortly after application. Do not use abrasive implements for cleaning, for example, scouring pads and steel wool are not recommended.
