Chem-Set 11.25 Inch Hook and Loop Sanding Disc, 150 Grit

Description

The 11.25 inch sanding disc is a 150-grit, film-backed abrasive for finish sanding with a compatible hook-and-loop backup pad. Aluminum oxide grain provides the cutting surface, while a non-loading stearate helps reduce material buildup during use. The large diameter is suited to orbital or dual-action sanding equipment designed for this disc size.

Finish Sanding Applications

This disc can be used on wood, paint, metal, plastic, cultured marble, and solid-surface materials when the machine, pad, and process are appropriate. The 150-grit grade sits in a useful intermediate range for refining scratches, leveling coatings, and preparing a surface for finer sanding steps. It removes less material than a coarse shaping abrasive and leaves a more controlled scratch pattern for the next finishing stage.

Film backing gives the abrasive a flexible, consistent base that can follow broad contours while staying stable under orbital motion. Hook-and-loop attachment makes disc changes straightforward and allows the abrasive to be removed from a compatible pad without adhesive residue. Check the pad face before installation so dust, torn hooks, or debris do not prevent full engagement.

Wet or Dry Process Use

The disc can be used in wet or dry sanding processes. Dry sanding keeps the workflow simple and makes the scratch pattern easy to inspect when adequate dust extraction is available. Wet sanding can help control loading and carry residue away from the work surface. The selected sander and backup pad must be approved for the chosen method, especially when water is present.

Start with a clean workpiece and center the disc on the backup pad. Use even machine movement and avoid holding the sander in one place, which can create heat or an uneven surface. Inspect the abrasive regularly. Replace it when cutting slows, loading cannot be cleared, the film is damaged, or the hook-and-loop backing no longer holds securely.
