Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains, including quartz, calcite, gypsum or various iron compounds. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone has a granular texture and may be found in almost any color, but the most common colors are tan, brown, yellow, red, gray, pink, and white. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.
Sandstone tiles vary in porosity and hardness however they are soft and porous on the other hand. Since sandstone tiles can absorb water very fast, it is important to follow proper sandstone tile cleaning methods in every opportunity to ensure proper maintenance.
