POWERTEC 10 PCS 80 Grit 8 Inch PSA Sanding Discs, Self Stick Adhesive Sandpaper, 8" for Drywall, Woodworking, Paint, Epoxy with Random Orbital Sanders, DA Sanders, 4x36 Belt Disc Sander (110550)

Let’s be real: when you’re shaping or finishing a board, consistency is everything. These PSA-backed discs (Pressure Sensitive Adhesive) slap down securely onto your 8” disc sander—no lift, no slippage, and they hold strong right through the job. And the 120 grit? That’s your sweet spot for rough smoothing of fiberglass, epoxy coatings, foam, or filler—aggressive enough to level, but fine enough to avoid deep gouges before finer grit.

Once I learned how to install one, these were great. Great adhesion.

Just what I needed

Fit like the original sanding disc that came with the sanding machine. I was surprised at the adhesive on the back of the new sanding Disc, it felt like there wasn’t enough adhesive on the back. I throughly cleaned the sanding wheel and placed the sanding disc on. I had no issues with it falling off.

These disks fit and have good adhesion with my sander and work well, they are very durable, and a good value for the money. Abrasion resistance seems good and they have good longevity.

I've had some disks in the past that refused to wear out. These are good, especially for the price, but there are superior options. I just need to find them. Can't go wrong for the price of these in my opinion.

I found this product economically priced and effective. I suspect the adhesion issues some users have complained about are because they did not clean the platen with of old adhesive using solvent and steel wool.

Worked perfectly
