Product Details
3M™ Wetordry™ paper sheet 431Q measures 9" x 11" and features 120 grit silicon carbide abrasive on a strong C-weight, waterproof paper backing designed for superior finishing in both wet and dry applications on substrates including paint, primer, gel coat, metal, and wood. The silicon carbide abrasive offers extra-fast cutting due to its sharp, easily fractured points that expose fresh edges, producing a smooth, professional finish particularly suited for low-pressure applications such as paint preparation and finishing on wood and metal. The paper sheet can be used dry or with water, allowing rinsing of both the work piece and abrasive surface to prevent clogging from dust and debris, reduce airborne dust, and accelerate cutting performance. The standard sheet size can be trimmed to fit specific applications, and the waterproof backing supports durability in wet environments while being lighter and smoother than cloth backing, making it preferable for lighter finishing tasks. This product is commonly utilized in the marine industry for sanding old finishes, fine feather edging, and surface work. The specific dimensions are 9 inches by 11 inches, with 120 grit silicon carbide abrasive on a C-weight waterproof paper backing, optimized for both wet and dry sanding. The package includes the single sheets as described, and the product complies with relevant industry standards for abrasive performance and backing waterproofing. Warranty terms apply as per 3M’s standard product warranty.
