plastered

Plastered is the past participle of plaster, a building material and the process of applying a plaster coating to surfaces such as walls and ceilings. Plastering involves applying coats of plaster to create a smooth or decorative finish. Common materials include gypsum plaster, lime plaster, and cement plaster. Plaster can be applied over lath, masonry, or modern drywall, and may be reinforced with fibers or mesh. After application, plaster is troweled and finished to achieve different textures; additional features such as cornices or mouldings may be formed before the plaster sets. Plastering often uses multiple coats, including a base coat, a setting coat, and a finishing coat.

As an adjective, plastered describes a surface that has been coated with plaster. A plastered wall or ceiling is typically even and durable when properly cured.

In colloquial English, plastered can also mean intoxicated or drunk. This slang usage originated in the early 20th century and is common in British English; equivalents in other dialects include hammered or wasted.

Plastered surfaces may require maintenance, such as re-plastering if cracked or damp; poor plastering can lead to defects like cracking, delamination, or efflorescence in lime plaster.
