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.

Trusted 3M Wetordry Quality

The 3M Wetordry Paper Disc 431Q offers reliable performance with the trusted 3M brand. This model features a 600 C-weight backing that balances durability and flexibility for sanding tasks.

Designed for easy use, the adhesive backing lets you quickly attach the disc to a random orbital sander. This ensures a secure fit and smooth operation during your sanding projects.

Precise Silicon Carbide Cutting

These discs use silicon carbide mineral, which cuts faster than aluminum oxide and delivers a smoother finish. This grade is ideal for professional results on various surfaces.

Silicon carbide's sharp edges stay fresh as they fracture, making the 431Q perfect for paint prep and finishing on wood and metal. It wears faster but leaves a superior finish compared to other abrasives.

Durable C-Weight Backing

The strong 600 C-weight paper backing provides durability for both hand and machine sanding. This backing supports consistent performance without tearing or wearing out quickly.

Its waterproof nature allows the disc to be used wet or dry, making it versatile for different sanding conditions. This backing helps maintain the disc’s integrity during tough jobs.

Versatile Wet Dry Use

This 12 inch by NH format disc is designed for both wet and dry applications. It works well on paint, primer, gel coat, metal, and wood, offering flexibility for many projects.

Using water with the disc reduces dust and debris buildup, which keeps the abrasive surface clean and enhances cutting speed. This versatility helps you achieve a professional finish in various conditions.

Convenient Pack Size Options

Available in packs of 50 per carton and 100 per case, these discs provide enough quantity for extended use. This pack size suits both individual users and larger operations.

The packaging ensures you have a ready supply of 3M Wetordry Paper Disc 431Q on hand, reducing downtime and keeping your sanding projects on schedule.
