The .062 In. aluminum backing is lightweight, yet strong for applying a rough or texture finish to plaste, concrete, or any sand surface. This popular coarse rubber pad is designed to smooth out irregularities on the surface and create a fine texture on plaster, stucco, and concrete applications. On wet surfaces compresses material to bring sand out to the surface for a coarse finish. The pad is 3/4 In. thick with a coarse finish that creates a cushioning and considerable wear before replacement. The precisely balanced 7-1/4 In. smooth wood handle is comfortable to grip. Proudly made in the USA.
