There are several types of plaster, each with its own unique properties and applications. Gypsum plaster, one of the most common types, is made from calcium sulfate and is known for its strength, durability, and fire resistance. Lime plaster, made from slaked lime, is more flexible and breathable than gypsum plaster, making it a good choice for areas with high humidity. Cement plaster, made from Portland cement, is known for its exceptional strength and durability, making it ideal for exterior applications or areas with heavy wear and tear.
