SANDING: Extra care should be taken during sanding and finishing, as sanding marks may become more apparent due to the tight grain, density, and light color of the species. It is often required to bring the sanding sequence to a higher grit to minimize visible scratches in birch. Birch can be difficult to stain and may appear blotchy.
