Designed specifically to rasp EIFS EPS foam walls, the DuraRasp is a heavily brazed #12 grit tungsten-carbide rasp. In ten months of testing by professional contractors, the product lasts 100 times longer than standard rasp paper. This custom-crafted and serial-numbered tool features non-foam gouging rounded corners and comfort-grip handles. Available in 2, 4, 6 and 8 inch widths, it’s easy to find just the right size to fit any job need. The company also offers self-adhering abrasive rasp paper that can be applied to any standard rasp tool. Using the 4-foot product can sometimes be more efficient as it addresses more surface area and assists in overall substrate flatness.
