USG Gypsum Plaster Accelerators are additives that shorten the setting time of gypsum plaster and setting-type joint compound by causing gypsum crystals to form at a much faster rate.
USG Gypsum Plaster Accelerator: Standard Strength is intended to provide a slight adjustment (10 to 30 minutes) to the setting time for veneer and conventional plasters.
USG Gypsum Plaster Accelerator: Alum/Catalyst corrects plaster dry-out conditions. It may also be used to treat sunfaded USG Imperial® Gypsum Base when a lime-containing plaster is to be applied.
