A tool and method for applying a texture material to a surface is provided. The tool comprises a body having a flat surface for mating to a smooth surface, such as a repaired portion of drywall. The body is formed of a rigid plastic material, that is optionally transparent, to enable to tool to be reused indefinitely, and has a multiplicity of spatially positioned openings disposed therethrough. Each of the openings has a predetermined configuration and position on the tool, for providing a pattern substantially matching the appearance of existing textured surface adjacent to the smooth surface. The invented method includes first affixing the tool to the smooth area of the surface, then applying a texture material to the smooth surface through the openings in the tool for forming a newly textured area that substantially matches the appearance of the existing adjacent textured surface.
