DAP® DryDex® Premium Lightweight Joint Compound is a ready-to-use joint compound for the smooth, high quality finishing of gypsum panel joints, nailheads and metal corner beads. The unique Dry Time Indicator signals when the next coat can be applied or it is ready to be sanded or painted. Our unique formulation generates 70% less airborne dust than other competitive low dust joint compounds creating less mess and faster clean-up. Lightweight formulation means less shrinkage so fewer coats are required than with other joint compounds. It works faster with less effort and weighs up to 25% less than conventional compounds for easier handling.
