Plaster, a pasty composition (as of lime or gypsum, water, and sand) that hardens on drying and is used for coating walls, ceilings, and partitions. Plastering is one of the most ancient building techniques.
What Is Plaster Made From?
Plaster is a construction material used for coating walls and ceilings. It is made from a mixture of water, lime, and sand. The lime is obtained from limestone, which is crushed and calcinated (heated to a high temperature).
The sand is obtained from quarries or rivers. The plaster is mixed with water to form a paste, which is then spread on the surface to be coated. The plaster hardens on contact with air and forms a smooth, hard surface.
Plaster has been used as a construction material for thousands of years. It was used in ancient Egypt and Greece, and it is still used in many parts of the world today.
Plaster is an inexpensive, durable, and easy–to–use material. It is easy to apply and can be shaped to create decorative designs. Plaster is also fire–resistant and sound–absorbing, making it an ideal material for use in homes and offices.
