This innovative joint compound provides an easier path to OSHA compliance with no additional steps, manpower or equipment. Independent industrial hygiene laboratory testing during sanding of Sheetrock® brand dust control joint compound has shown levels of total dust reduction and respirable crystalline silica below detectible limits in reference to OSHA's new silica rule. With Sheetrock® brand dust control joint compound, fine dust particles bind during sanding to form heavier particles that drop to the floor, creating less dust and easier clean up.
