Sand Maker is a safe and effective product to soften concrete splatter and dust. This safe blend of proprietary detergents and builders loosens over an extended dwell time. It is easy to handle and use. Non corrosive to ferrous metals or to the skin. This is a ready to use product. Apply as is and turn the splatter back into sand. Flush off with a high pressure rinse. Best if applied at the end of the day and allowed to sit over night to soften.
