The paper sheets measure 9 inches by 11 inches, and there are 50 sheets per inner pack, with a total of 500 sheets per case.
-
What is the weight or grit level of these sandpaper sheets?
These wet/dry sandpaper sheets have a C-weight backing and features silicon carbide abrasive mineral, which offers great durability as well as uniform finishing. Additionally, they have an abrasive grit rating of P400 (coarse).
-
Can I use these wet/dry sandpaper sheets for various applications?
Yes! These versatile paper sheet can be used on automotive surfaces such as clear coats, primers or paints; metalwork; plastics; composites; fiberglass gelcoat including scratch refinement during step one (400 grit) of the three-step body repair process. They produce outstanding finishes throughout their life span thanks to its super sharp abrasive minerals.
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.
