The sharp grains increase the aggressiveness of the abrasive enabling faster material removal. Each stroke removes a significant amount of material from the workpiece. This rapid removal increases the surface roughness. Coarse sanding is recommended before subsequent sanding steps with a finer grit. The d-paper backing is extremely tear-resistant yet remains flexible. The ps 30 d roller offers users an excellent price-to-quality ratio.reliable efficient and fastthe ps 30 d roller sands wood varnish and paint layers precisely and quickly. The sharp grain requires special attention to the working direction when sanding wood – sanding along the grain. Sanding perpendicular to the grain can result in chips being torn out and deep burrs forming. Before working on varnish and paint layers use a putty knife or other sharp edge to check for any loosely bonded areas. Removing these loosely bonded layers before sanding minimizes the time and effort of subsequent work. No additional accessories are needed for hand sanding however to achieve precise sanding we recommend attaching the ps 30 d roll of sandpaper to the sanding block.areas of application:-wood-paints-varnishes-putty-metal universal**the picture shown is for illustrative purposes only.
