Wall texture is a decorative finish that enhances the visual appeal of interior and exterior walls. It adds depth, style, and a unique pattern to plain surfaces while effectively hiding imperfections. Common types include orange peel, knockdown, swirl, and popcorn textures. Applied using tools like rollers, trowels, or spray machines, it suits both modern and traditional settings. Wall textures are durable, easy to maintain, and elevate the overall ambiance of any space.
