Plastering is a construction technique used to create a smooth and even surface on walls and ceilings. It involves applying a mixture of gypsum, lime, or cement with water to a surface, which hardens over time. This process not only enhances the appearance of a room but also provides protection against moisture and damage. There are different types of plastering, including internal plastering for indoor surfaces and external plastering for outdoor walls. Skilled workers known as plasterers use various tools, such as trowels and floats, to achieve the desired finish. Proper plastering can improve insulation and soundproofing in buildings.
