Use this A511/A513 coarse-grit paper sheet dry on bare wood before coating to achieve an excellent, consistent finish, thanks to the natural garnet abrasive. This paper sheet, which is ideal for use on softwoods such as pine, is available with either A511 A-weight or A513 C-weight backing for use with your sanding board or block. It’s a superb choice for commercial contractors and DIYers to use for moderate-to-heavy material removal.
