Still a Favorite

3M™ Wetordry™ Paper Roll 431Q is a popular abrasive product among customers due to its reduced clogging, long life, and great finish. It is effective on substrates from paint, primer, and gel coat to metal and wood. This abrasive product comes in rolls 50 linear yards in length by 6 inches wide in 10 grades from 60 to 600 grit as well as make-to-order forms. Customers choose this popular abrasive in roll form because it's easy to cut to custom sizes on the spot.

Sharp Mineral for a Smooth Finish

3M designed this roll with silicon carbide, which is second only to diamond in hardness. This mineral's grain is sharp and narrow and easily fractures. The benefit of this "friability" is that fresh, sharp edges are continuously exposed to the work surface. They cut extra fast and produce a smooth, professional-looking finish. Silicon carbide abrasives are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While the mineral has a shorter life than aluminum oxide, it produces a superior finish.

3M Proprietary Waterproof Backing

3M™ Wetordry™ Paper Roll 431Q abrasive can be used dry or with water. It enables you to rinse areas of the workpiece and the abrasive during use, preventing dust and debris from clogging the face of the abrasive and reducing air-borne dust. It also cools and lubricates the workpiece and produces a faster cut, extending abrasive life. This abrasive is backed with a 3M-patented durable waterproof paper backing. Lighter weight than cloth and smooth rather than textured, a paper backing works better for lighter applications like finishing and paint prep. Sanding with water can minimize the effects of dust and clogging of abrasive points.

PSA Attachment System Is an Option

This abrasive roll comes with a pressure-sensitive adhesive (PSA) or regular backing. The PSA backing provides an attachment suitable for high heat and more severe sanding applications.

Recommended Applications

This versatile abrasive roll is ideal for use on surfaces that tend to generate a lot of dust, such as paint and primer, and can also be used dry for finishing metal and gel coats. In the marine industry, 431Q abrasive media is used for sanding old finishes, fine feather edging, and surface work.

Engineered to Improve the Process from Beginning to End

3M™ Wetordry™ Paper Roll 431Q is engineered to improve the sanding process from beginning to end. This abrasive makes the sanding processes easier. It's made to cut fast and endure wet sanding so jobs that generate dust don't fatigue it. It's made to deliver a great finish. It's another way that 3M helps you get the most from your operations.
