Plastering Plastering is a crucial finishing process in construction that involves applying a protective and decorative layer of plaster to walls and ceilings. This technique enhances the durability, strength, and appearance of surfaces by providing a smooth, even finish. Plaster is typically made from a blend of materials such as cement, gypsum, lime, or sand, depending on the application and desired finish. It helps in sealing cracks, covering imperfections, and preparing surfaces for painting or wallpapering. Plastering not only improves aesthetics but also enhances thermal and sound insulation, making it an essential step in both residential and commercial construction projects.
