Dust Control Drywall Compound Drying Time

All surfaces including applied drywall compound must be thoroughly dry dust free and not glossy before decorating.

Dust control drywall compound drying time.

Joint compound with dust control features a unique formula that binds up fine residue during sanding to form heavier particles that tend to fall to the floor instead of clouding the air. Drying time hours 24 h. 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. The clumps are heavy enough to drop to the floor rather than float into the air like regular powdery drywall sanding dust.

The priming material must be suitable for the substrate and applied as recommended. This innovative joint compound provides an easier path to osha compliance with no additional steps manpower or equipment. Drywall joint compound manufacturers are hesitant about providing targeted drying times preferring instead to provide a wide spectrum and then leave the rest up to the user. Joint compound should generally be allowed to dry for 24 hours between coats and before sanding painting or priming.

A priming material applied over the entire prepared gypsum panel surface prior to decoration. The idea behind dust control joint compound is that it applies like regular joint compound but its modified formula makes the dust heavier and cause it to clump as you sand. High humidity levels and warm temperatures both increase drying times however.
