Knocked down wall texture is a popular decorative finish applied to interior walls and ceilings. Created by partially removing wet joint compound or plaster, it produces a distinctive, roughened surface that adds depth and character to spaces. Available in various types such as knockdown, skip trowel, and stipple, these textures enhance wall protection and durability. They are applied using tools like hawks and trowels, and can be customized to suit specific design aesthetics and functional requirements.
