Filling holes and casting repairs, this 25 lb. bag of plaster is a fast-setting gypsum plaster that mixes with water to a smooth paste, then sets rock-hard in minutes to fill holes, patch walls and ceilings, set hardware, and cast shapes. Poured or troweled into a hole or mold, it expands slightly as it sets to grip tightly and cures to a dense, sandable, paintable surface harder than ordinary spackle. It is the classic material for anchoring bolts and brackets in masonry, repairing plaster walls, and craft and mold casting. Mixed in small batches as needed, it is a shop and maintenance staple for hard, fast repairs.
