USG Gypsum Plaster Accelerator / Standard - 1.5 lb Bag

Reduce the setting times of plaster, setting-type joint compounds and gypsum cements. Two formulations meet a variety of accelerated setting requirements.

USG Gypsum Plaster Accelerators are additives that shorten the setting times for gypsum plaster and setting-type joint compounds by causing gypsum crystals to form at a much faster rate.

Safe and easy-to-use, USG Gypsum Plaster Accelerators are available in the following formulations

• USG Standard Strength Gypsum Plaster Accelerator reduces set times for veneer and conventional plasters by 10 to 30 minutes
• USG Accelerator — Alum Catalyst helps correct plaster dry-out conditions and may also be used to treat sun-faded USG Imperial® Gypsum Base before a lime-containing plaster is applied
