3M™ Wetordry™ Paper Sheet 431Q features extra-fast cutting silicon carbide on a strong C-weight, waterproof paper backing to provide superior finishing for both wet and dry applications on a variety of substrates, including paint, primer, gel coat, metal, and wood.
Used dry or with water, 3M™ Wetordry™ Paper Sheets enable the user 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 sheets are ideal 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 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 carbide is a very hard mineral 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.
Our 3M™ Wetordry™ products are backed with our 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.

High Quality Construction
The 3M™ Wetordry™ Abrasive Sheet 413Q is best suited for metal sanding and finishing thanks to its versatility and fast cutting abrasive material. Its flexible, A-weight paper backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing.
Silicon Carbide Grain
This paper primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard but 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 cleaning and finishing on paint and metal.
Waterproof and Heat Resistant
This paper also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft surfaces. This also allows for faster sanding and a higher cut rate. The waterproof coating enables the user to rinse areas of the workpiece and the paper during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.
