Silverline 150mm 120 Grit Self Adhesive Sanding Discs – Key FAQs

• What is 120g best used for on a 150mm disc sander?
  120g is ideal for general preparation and smoothing, refining surfaces after coarser sanding and getting wood or coatings ready for finishing or painting.

• Are these discs hook and loop or self-adhesive?
  These are self-adhesive (PSA) discs. They stick directly to a compatible 150mm backing pad—ideal where hook and loop fixing isn’t used.

• Can I use these on a bench-top disc sander?
  Yes. They’re compatible with 150mm bench-top disc sanders, as well as air and electric sanders with 150mm backing pads.

• Why are the discs non-perforated?
  Non-perforated discs are designed for pads without extraction holes. If your machine uses extraction through holes, consider perforated discs for improved dust control.

• How can I make sanding discs last longer?
  Use light pressure, keep the work area dust-free, and clean the abrasive as it loads up. A sanding disc cleaning block can remove clogging quickly and efficiently.

• What grit should I use before or after 120 grit?
  Start with a coarser grit (like 60 or 80) for heavier removal, then move to 120 for smoothing. For finer finishing, step up to 180–240 depending on the surface and coating.
