Plaster finishes are a type of surface treatment applied to walls and ceilings, providing a smooth and durable finish. They are made from a mixture of materials, typically including gypsum, lime, or cement, which are combined with water to create a paste. Once applied, plaster can be textured or left smooth, depending on the desired aesthetic. These finishes serve both functional and decorative purposes. They help to protect underlying structures from moisture and damage while also enhancing the visual appeal of a space. Common types of plaster finishes include stucco, venetian plaster, and lime wash, each offering unique characteristics and styles.
