Binds fine residue during sanding to form heavier particles that drop to the floor instead of clouding the air. Offers all of the benefits of a Sheetrock brand ready-mixed joint compound but in a lighter, less messy formula. Uses two coats over metal such as corner beads and fasteners. Bonds like a taping product for a tough, tight bond under most job conditions. Combines all-purpose, single-package convenience with optimum taping and topping performance.
