Wall finishing refers to the final treatment applied to interior or exterior walls to enhance their appearance and protect them from damage. Common methods include painting, wallpapering, and applying textured finishes. These techniques can improve aesthetics and durability, making spaces more inviting and functional. In addition to visual appeal, wall finishing can also contribute to insulation and moisture resistance. Materials like drywall or plaster are often used as a base before applying the finishing layer. Proper wall finishing techniques can significantly impact the overall quality and longevity of a building's interior and exterior surfaces.
