Plaster is a building material predominantly used to create smooth surfaces on internal walls and ceilings, offering both strength and visual benefits within a property. Plastering has been used in some form for thousands of years, with ancient Greeks using plaster for the exteriors and interiors of temples.

Lath and plaster methods have mostly been replaced with modern drywall or plasterboard, which is faster and less expensive to install. Drywall possesses poor sound dampening qualities and can be easily damaged by moisture.

For one thing, plaster is by nature a more durable finish than drywall, even high-level drywall finishes. In addition, plaster outperforms drywall in a number of key areas, including insulation, soundproofing, and fireproofing. One additional point in plaster's favor is that by nature, mold can't grow in plaster.
