Abrasive Rolls

An abrasive roll is continuous stock cut to whatever length the job needs, instead of working to the fixed size of a sheet. Two different products sit on this page: cloth backed rolls that remove material, and foam backed rolls that finish the surface.

Cloth rolls and foam rolls

The cloth roll (147 grade, 200 mm x 50 m) is aluminium oxide on cotton-polyester cloth. Cloth resists tearing and folding in a way paper does not: a strip cut from the roll is wrapped round pipe, shafting or a profile and pulled from both ends. This is stock removal, deburring and surface cleaning.

The foam roll (Gold series, 115 mm x 25 m) carries the abrasive on flexible foam. The foam sits the abrasive down onto the shape of the surface; pressure stays even over mouldings, chamfers and edges, and there is no line where a flat block would have borne. This is flatting primer and cutting back between coats.

The rule is simple: cloth to remove material, foam to finish it.

Grit sequence: why a grit is not skipped

Sanding is not removal so much as scratch replacement. Each grit replaces the scratch the last one left with its own finer scratch, and what remains at the end is the scratch of the last grit used.

That is why skipping a grit spoils the result. Going from 80 straight to 400, the fine grain cannot reach the bottom of the deeper scratch and only polishes its edges — the surface feels smooth to the hand but the scratch reappears under paint or polish. The practical sequence runs 60-80-120-180-240-320-400, each grit worked until the previous one's scratch is no longer visible.

Grit bands and what each is typically used for.

Why a roll rather than sheets

A sheet is a fixed size and every piece cut from one leaves an offcut. A roll gives exactly what is needed: a 10 cm strip and a one metre length come off the same roll. Consumption falls to what the job uses.

On continuous work the second advantage is stock: one roll per grit, rather than sheets held in several sizes. Rolls are sold by the metre and what is left is visible at a glance.

Frequently Asked Questions

  • What size is the cloth roll?

    The 147 grade cloth roll is 200 mm wide and 50 metres long, cut to length as needed.

  • Can a foam roll be used on a machine?

    Yes, on a suitable pad — but its real use is folded into the hand for profiles, edges and mouldings, which is where the foam backing earns its place.

  • Can abrasive rolls be used wet?

    Cloth rolls are worked dry as a rule. For wet sanding, use wet and dry sheets, which are coated on a waterproof backing.

  • Which grits are available?

    Cloth rolls are listed from 36 to 400 grit and foam rolls from 80 to 400 grit. The table above gives the band for each job.
