3M™ Sanding Screen Sheet 483W, 80, 3 in x 6-3/8 in

The 3M Sanding Screen Sheet 483W is a unique product that features an open mesh backing and a sharp, fast-cutting abrasive mineral. This sheet, commonly known as "drywall paper," is designed to resist loading on soft woods, drywall, and metal. Its open-mesh cloth backing minimizes loading and withstands the friction and heat generated during continuous sanding. It is particularly suitable for plaster, drywall, and other substrates that would typically cause conventional abrasives to clog due to the fine dust they generate.

This sheet is also suitable for wet applications due to its waterproof resin bond. It is available in six different grades ranging from 60 to 180.

Silicon carbide is a hard and brittle mineral that fractures easily, resulting in freshly exposed sharp edges. This characteristic allows it to cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint preparation and finishing on wood and metal. Although it wears faster than aluminum oxide, it delivers a superior finish.

The 3M Sanding Screen Sheet 483W is frequently used in white metal repair operations. When car bodies are welded together, they often have oily surfaces. The open mesh backing of this abrasive is particularly useful in such cases.

Stamping operations can leave imperfections on car panels. 3M screen cloth products are used to lightly sand the panels, causing high spots to shine a little brighter. The screen cloth works well in this application because the oily surface does not cause loading.
