Use the natural garnet abrasive of this A511/A513 fine grit paper sheet with your sanding board or block on soft woods, such as pine, when you want a consistent, excellent finish. This paper sheet is a great choice for smoothing and fine surface prep and it's available with both A511 A-weight and A513 C-weight backing for heavy duty or lighter duty sanding. For the best results, use this abrasive sheet dry on bare wood before coating; this sheet works great for commercial contractors and DIYers alike.
