Silica sand, known as quartz sand, is a naturally occurring mineral of silicon dioxide (SiO2) particles. It has a granular and gritty texture, making it an ideal abrasive for preparing surfaces before painting. Silica sand's hardness and resistance to high temperatures also contribute to its importance in the paint industry.

Crystalline silica commonly occurs in nature as the mineral quartz, and is found in granite, sandstone, quartzite, various other rocks, and sand. Workers who inhale very small crystalline silica particles are at risk for silicosis — an incurable, progressively disabling and sometimes fatal lung disease. Silicosis results in permanent lung damage.
