40gm Yellow Oxide P40 5M x 115mm

This P40 yellow oxide sanding roll provides the same coarse abrasive performance recommended for sanding cured GRP laminate — but in a convenient tear-to-length roll format designed for efficient on-site use.

Perfect for roofers and installers who need fast access to sanding material without carrying stacks of pre-cut sheets. Simply tear the required length and load into your hand or pole sander, reducing waste and speeding up preparation work.

Why P40 grit is ideal for GRP roof preparation

• Removes sharp glass fibre spikes after lamination
• Flattens overlaps, resin build-up and high spots
• Creates the mechanical key required for topcoat adhesion
• Helps prevent pinholes and capillary water ingress

Why a sanding roll is ideal on the job

• Tear exactly the length you need — less waste
• Quick reloads when sanding large roof areas
• Easy to store and transport in tool kits and vans
• Works perfectly with hand sanders and pole sanders
• Ideal for both large surfaces and detailed trim work

Important sanding guidance

Always ensure the laminate is fully cured before sanding. Sanding laminate that is still “green” will clog abrasives and slow the preparation process.

Once cured:

1. Sand the laminate using P40 grit

2. Remove dust thoroughly

3. Wipe down with acetone

4. Apply GRP topcoat

Efficient sanding preparation is key to achieving a smooth, professional and long-lasting GRP roof finish.
