Use With USG Gypsum USG Gypsum Accelerator (High Strength) when added to Sheetrock Brand Lightweight Setting Type Joint
Accelerator
Compound (eaSy Sand) will shorten the setting time. USG Gypsum Accelerator should be sprinkled in dry form
into the mixed compound. For hand mixing, dry accelerator can be added either to the dry mix or mixed
compound. Never add USG Gypsum Accelerator directly to water or mix it with water to form a solution before
adding it to the compound. Doing so will significantly reduce its ability to accelerate the set.
