Sandstone
Sandstone is a sedimentary rock consisting usually of fine grains of silica quartz, and feldspar “cemented” together with fossils, clay, calcium carbonate and iron oxide. Sandstone is extremely durable and hard wearing being mainly silica, varying in colour, texture, layering and composition.
Because of impurities sandstone varies from natural silica colours such as off-white, yellow, browns, beige and mustard to pinks, greens and reds. Sandstone is used internally and externally on floors, walls and building facades. Most sandstones are acid resistant although certain sandstone colours have naturally occurring iron oxide which will rust or change colour after acid washing. Natural sandstone has a rough, granular surface texture and requires sealing to facilitate easier cleaning. Sandstone in general is porous and requires sealing to reduce staining. Sandstone is available in blocks, tiles and cladding; either polished, honed or natural.
