| 释义 | plaster (once / 589 pages) 1nv 2nv Plaster is a building material that's applied as a wet paste and dries very hard and smooth. The walls inside your house might be made of plaster. New houses typically have interior walls made of drywall, rather than plaster, but older homes usually have many plaster surfaces. Plaster starts as a mixture of lime, gypsum, sand, or cement that's mixed with water. This soft substance is applied to surfaces where it hardens — either for walls, works of art, or as casts used to hold broken bones steady. In Britain, a plaster is also a sticky bandage, while an American would call this a Band-Aid.
