Frequently Asked Questions

What is the difference between hook-and-loop and adhesive-backed sanding discs?

Hook-and-loop discs attach to a matching sanding pad using a Velcro-like system, allowing quick and easy swapping without leaving adhesive residue. Adhesive-backed (PSA) discs stick directly to the pad with a pressure-sensitive adhesive. Hook-and-loop is more convenient for repeated disc changes.

Are these sanding discs suitable for wet sanding?

Our standard abrasive disc sanding paper is designed for dry sanding. For wet sanding applications, we recommend using a waterproof version. The paper backing in this product is not waterproof and may break down when exposed to water.

What grit size should I use to remove rust or scale?

For heavy rust removal, start with a coarse grit such as P40 or P60. Once the majority of the rust is removed, progress to medium grits like P120 or P180 to smooth the surface further before priming.

Can these discs be used on a rubber backing pad?

Yes, they are designed to work with standard 125 mm sanding pads with a hook-and-loop interface. Always ensure the pad is compatible with the disc diameter and backing style.
