3M Wetordry Paper Disc 431Q features extra-fast cutting silicon carbide on a strong, waterproof paper backing that gives you superior finishing for both wet and dry applications on a variety of substrates.

Used with water, our 3M™ Wetordry™ discs enable you to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust, while producing a faster cut at the same time. These versatile discs are ideal on surfaces that tend to generate a lot of dust, such as paint, primer, and wood; and can also be used dry for finishing metal and gel coats. The adhesive backing provides easy attachment to a random orbital sander.

We chose silicon carbide, a mineral that is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.

3M™ Wetordry™ products are backed with a 3M proprietary durable 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.

Strong C-weight Backing

This sanding disc features a strong C-weight paper backing, which provides durability whether you’re sanding by hand or using a machine. The backing supports consistent performance across various applications.

The C-weight paper backing also contributes to the disc’s versatility, making it suitable for both wet and dry sanding tasks. This durability helps extend the life of each disc during use.

120 C-weight Grade

The 120 C-weight grade of this disc offers a balanced abrasive level, perfect for smoothing surfaces without removing too much material. This grade is well-suited for finishing tasks on paint, primer, and wood.

Using the 120 grade ensures a professional finish while maintaining control over the sanding process. It’s a versatile choice for a range of materials and projects.

12 Inch Size Format

Measuring 12 inches in diameter with a NH (non-hole) format, this disc fits many standard random orbital sanders. The size allows for broad coverage and efficient sanding on larger surfaces.

The 12-inch dimension is ideal for both detailed and extensive sanding jobs, providing a good balance between control and speed. The NH format means no pre-cut holes, suitable for sanders without dust extraction ports.

Wet Or Dry Use

The 3M Wetordry Paper Disc 431Q is designed for use in both wet and dry sanding applications. Its waterproof backing supports wet sanding, which helps reduce loading and speeds up cutting.

Wet sanding with this disc reduces dust and debris buildup, improving the finish quality on surfaces like metal, gel coat, and wood. The pack size of 50 discs per carton ensures you have plenty of discs for multiple projects.
