The ProSand A259PS coarse grit paper sheet, made with a premium heat-treated abrasive, delivers faster cutting and longer-lasting performance than standard paper, making it ideal for heavy material removal. It works well with sanding boards or for hand-sanding on fiberglass, composites, metals, and woods. Featuring a latex-saturated, fiber-reinforced backing for flexibility and tear resistance, it also boasts a water-based stearate coating to resist clogging and prevent color transfer.
