The C420 Standard Sanding Sheet for Wood and Paint is ideal for sanding wood and paint. The C/D paper backing is flexible and conforms to the work surface, allowing for contour sanding. The sheet has a long lifespan, as it prevents breakage and loss of grit. The hard aluminum oxide grain enables high material removal and consistent surface quality. This product is designed for hand sanding of wood, wood materials, and veneers, and is suitable for sanding paint on flat and curved surfaces. Additionally, it is the optimal choice for roughening and sanding paints, lacquers, primers, and fillers, as well as for fine sanding of sharp edges.
