Reduce the setting times of plaster, setting-type joint compounds and gypsum cements.
The gypsum plaster accelerator aims to provide a slight modulation (10 to 30 minutes) to the setting time of thin plasters and conventional plasters. Reduce setting times for plaster, chemically set joint compounds and cements.
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
