FAQs
Can these discs be used on a random orbital sander?
These specific discs are PSA (self-adhesive) and are intended for flat backing pads or block sanders, not hook-and-loop (Velcro) orbital sander pads.
What is the primary benefit of P180 grit?
P180 is a medium-fine grit that is perfect for intermediate sanding, removing small imperfections and preparing wood surfaces for painting or finishing.
Does this box contain 100 individual discs?
Yes, each box contains exactly 100 units of the 150mm PSA discs.
Can I use these on metal surfaces?
While optimized for wood and plaster, they can be used for light surface cleaning on metal, though they are not specialized metalworking abrasives.
How do I remove the disc after use?
Gently peel the edge of the disc up. If residue remains on the pad, use a light adhesive remover or mineral spirits to clean it before applying a new disc.
Troubleshooting
Disc loses adhesion mid-sanding
Clean the backing pad with a degreaser or solvent to remove dust and residue before applying a new disc.
Abrasive is clogging rapidly
Ensure that the sanding speed is adjusted for the specific material and check that the dust extraction system is functioning correctly.
Pros and Cons
Pros
- High-quality, uniform sanding finish
- Versatile application across multiple materials
- Secure PSA adhesive backing
- Excellent resistance to clogging
- Cost-effective bulk quantity
Cons
- Requires clean backing pads for adhesion
- Not suitable for heavy-duty stock removal compared to lower grits
- Disposable nature creates constant consumable waste
Setup, Compatibility & Care
To ensure peak performance, apply the disc to a clean, dry, and dust-free backing pad. Peel the protective backing liner off carefully to avoid damaging the adhesive surface. Press firmly from the center outward to eliminate air bubbles for a secure fit.
When storing the discs, keep them in a cool, dry environment. High humidity can degrade the effectiveness of the PSA backing, making it difficult to attach or remove from your tools. When transitioning between materials, periodically inspect the surface for resin buildup and replace the disc as soon as the abrasive loses its cutting efficiency.
