Adhesive Discs

PSA Adhesive Discs for Surface Prep, Smoothing & Finishing

Adhesive (PSA) sanding discs are designed for consistent, repeatable sanding—ideal for surface prep and finishing workflows where control matters. They’re commonly used for smoothing, leveling, and prep steps before coatings or final finishing.

Choose discs by grit: coarser for removal and leveling, medium for smoothing and blending, and fine grits for finish prep.

Common Uses

  • Surface prep and sanding workflows.
  • Smoothing and leveling.
  • Prep before coatings or finishing.
