RSA Patch Smooth is used as a patching compound to fill defects that appear in concrete and masonry surfaces. Once the surface has been patched and the product has dried, it is then ready for application of a protective coating. In the case of severe defects, multiple coats of Patch Smooth can be applied.
It is easily sanded and can be polished with a steel towel for a ‘white set’ and glossy appearance internal finish.
Patch Smooth can also be used as an overcoat to Patch Coarse and Patch Fine applications if a smoother finish to the surface is required.
