3M Wetordry Paper Sheet 431Q features extra-fast cutting silicon carbide on a strong C-weight, waterproof paper backing to provide superior finishing for both wet and dry applications on a variety of substrates, including paint, primer, gel coat, metal, and wood. Versatile sheet can be used wet or dry on paint, primer, gel coat, metal, and wood. Waterproof backing supports wet applications for decreased loading and a faster cut. Strong C-weight paper backing provides durability for either hand or machine sanding. Silicon carbide mineral cuts faster than aluminum oxide and produces a smoother finish. Sheet is standard 9 x 11 and can be sized according to task.


Our 3M Wetordry products are backed with our proprietary waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.
