3M Hookit Clean Sanding Roll – P40, 115mm (THR-34460)
When you need maximum cutting power for the most demanding surface preparation jobs, reach for the 3M Hookit Clean Sanding Roll (THR-34460) — a P40 grit, 115mm wide hook-and-loop abrasive roll built for aggressive material removal on hulls, decks, and composite surfaces. Whether you’re stripping multiple layers of antifouling paint, removing old gelcoat, or levelling heavy fairing compound, P40 grit delivers the fastest cut rate in the Hookit Clean Sanding lineup.
Key Features
- P40 Grit – Extra-coarse grit for maximum material removal; ideal for stripping heavy paint buildup, old antifouling, thick filler, and damaged gelcoat
- Hookit Hook-and-Loop Attachment – Attaches and detaches instantly from compatible 3M Hookit sanders — no adhesive backing required for fast, tool-free disc changes
- Clean Sanding Technology – Open-coat abrasive structure with anti-loading coating resists clogging for extended abrasive life and consistent aggressive cut rate
- 115mm Width – Fits standard 115mm Hookit sanding pads; compatible with 3M random orbital and straight-line sanders
- Roll Format – Cut to the length you need for custom pad sizes or hand sanding; minimizes waste and maximizes material value
- Durable Aluminum Oxide Abrasive – Tough cutting mineral maintains performance across fibreglass, gelcoat, wood, epoxy filler, and painted surfaces
