PRODUCT FAQ
-
What makes 3M™ Wetordry™ Paper Sheet 431Q better than other sandpapers in the market?
One of the main advantages of our Wetordry paper sheet is that it can be used with water or oil, which helps reduce clogging and extends abrasive life. It also features a tough resin bond for durability, consistent finish, and long belt life.
-
Can this product be used for wet sanding on all surfaces including automotive paints?
Yes! Because our Wetordry paper sheet can be used wet or dry, making it suitable for use as an automotive paint sandpaper.
-
How many sheets are included in a case of 3M™ Wetordry™ Paper Sheet 431Q?
Each inner pack contains 50 sheets; each case has five inner packs (totaling to250 sheets). This package size works well if you're doing extensive surface prep work as part of larger projects.
3M™ Wetordry™ Paper Sheets are a versatile abrasive product that can be used dry or with water. They are designed to prevent dust and debris from clogging the abrasive points, while producing a faster cut at the same time. These sheets are ideal for surfaces that tend to generate a lot of dust, such as paint and primer. They can also be used dry for finishing metal and gel coats. In the marine industry, they are used for sanding old finishes, fine feather edging, and surface work. The standard 9 inch x 11 inch sheets can be cut to size for the application.
Silicon CarbideSilicon carbide is a very hard mineral that is characterized by sharp points that fracture 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 the mineral has a shorter life than aluminum oxide, it produces a superior finish.
Waterproof Paper Backing3M™ Wetordry™ products are backed with a 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.
