Plaster
Plaster is a construction material used for coating walls and ceilings to create a smooth or decorative surface. Made by mixing materials like cement, lime, gypsum, or clay with water, plaster is applied to cover rough surfaces, provide a finished look, and protect structures from environmental factors.
There are several types of plaster, including cement plaster, lime plaster, and gypsum plaster, each serving specific purposes. Cement plaster is commonly used for exterior walls due to its durability and weather resistance, while gypsum plaster is preferred for interiors because of its smooth finish and quick setting time. Lime plaster, known for its breathability and flexibility, is often used in heritage restoration projects.
The application process involves surface preparation, ensuring that the base is clean and free from dust or grease. A bonding agent may be applied to improve adhesion. The plaster is then mixed to the desired consistency and applied in layers using trowels, followed by finishing to achieve a smooth or textured appearance.
Plaster offers numerous benefits, including enhanced aesthetics, improved insulation, and protection against moisture. It also helps in concealing wiring and uneven surfaces, creating a polished look. However, improper mixing, poor surface preparation, or insufficient curing can lead to issues like cracking or flaking.
