<p>To apply a texture exterior wall finish, first clean the surface to remove dirt and debris. Use a primer to ensure better adhesion of the texture paint. After preparing the surface, apply the exterior texture paint with a roller or spray machine, depending on the type of texture. Depending on your chosen finish, use a brush or trowel to create patterns or smoothness for a bolder texture design. Allow the texture to dry and finish with a protective sealant for enhanced durability. This technique ensures your exterior wall texture design lasts longer and looks fantastic.</p>
