Product Information
Full details
The Mirka Gold 150mm P320 sanding disc is designed for professionals and DIY enthusiasts who require a reliable, high-quality finish on wood, plaster, filler, and varnish. Its primary benefit is the combination of versatile abrasive performance and the secure PSA (Pressure Sensitive Adhesive) backing that prevents shifting during intense sanding sessions; however, users should note that the adhesive backing requires a compatible PSA backing pad or flat surface to operate effectively, as it does not use a hook-and-loop system.

FAQs
Does this disc use Velcro?
No, this is a PSA (Pressure Sensitive Adhesive) disc and does not have hook-and-loop backing.
Can I use this for wet sanding?
The Mirka Gold range is primarily designed for dry sanding applications.
Is P320 grit too coarse for wood?
P320 is considered a fine grit, making it excellent for final sanding, removing grain raise, or prepping for paint.
Can I reuse these discs?
These discs are intended for single use; once removed, the adhesive will typically lose its tackiness.
What tools are compatible with these discs?
They are compatible with any 150mm flat-face backing pad designed for PSA adhesive discs.
Troubleshooting
Disc is not sticking to the pad
Ensure the backing pad is clean and free of sanding dust; use a dry cloth to wipe the surface before applying a new disc.
Adhesive residue left on tool
Gently rub the residue with an adhesive remover or a soft cloth dampened with a mild solvent, then wipe dry.
Disc tearing during use
Reduce downward pressure and ensure the disc is applied perfectly flat without air bubbles trapped underneath.

Setup, Compatibility & Care
To use the Mirka Gold PSA discs, ensure your backing pad is clean, dry, and free of dust. Peel the protective backing liner from the disc and press it firmly onto the center of your sanding tool. When finished, peel the disc off carefully; if adhesive residue remains on the pad, use a light solvent or adhesive remover to clean the surface before applying the next disc. Always store unused discs in a cool, dry place to prevent the adhesive from drying out or collecting dust while in storage.
