Buying guide

Choose Flat Roofing Tools for getting the tools needed to apply resin, matting, topcoat or GRP roofing details.

Good choice when

  • Use this category for getting the tools needed to apply resin, matting, topcoat or GRP roofing details.
  • Use it when the surface is GRP roofing systems and prepared flat roof details.
  • Use it when the measurements, preparation work and related accessories have been checked.

Consider another route when

  • Do not use this category when you are looking for the waterproofing materials rather than installation tools.
  • Do not use it when the roof is unsafe or unsuitable without preparation.
  • Do not use it as a shortcut if another CRS system is a better fit.

Next step: Match the tools to the GRP system, roof size and application stage before ordering.

The Right Roller For Each Stage

Resin application uses a standard fluffy roller to spread resin across the deck and into the mat. The bubble buster stage uses a DECO paddle roller โ€” the castellated profile breaks up trapped air pockets and consolidates the mat against the resin. Without adequate bubble-busting, air voids remain in the laminate and create weak spots that show as white patches and eventually crack or delaminate. Topcoat uses its own separate set of clean fluffy rollers โ€” any resin contamination on the topcoat roller produces drag marks and an uneven finish.

Mixing Cups and Catalyst Accuracy

Catalyst must be measured accurately by volume, not estimated. A graduated mixing cup is an inexpensive item that eliminates the guesswork. Too little catalyst in a batch can result in a soft, undercured laminate. Too much shortens the working time to the point where the mat cannot be fully wet out before the resin gels. A proper mixing cup costs less than the resin wasted in a single botched batch.

Frequently asked questions

What is the difference between a fluffy roller and a bubble-buster roller?

A fluffy roller spreads and applies resin. A bubble-buster paddle roller (DECO roller) is used after the mat is laid to consolidate it against the wet resin and expel trapped air. Both are needed โ€” the fluffy roller applies, the paddle roller consolidates.

Why do I need separate rollers for topcoat?

Resin contamination on a topcoat roller causes drag marks and an uneven finish on the final surface. Keeping a separate set of clean rollers for topcoat avoids this problem entirely.

Which bucket size should I use for mixing resin?

Match the bucket size to the batch size. A 3L bucket suits small batches on a cold day or detailed work where a short working time is needed. The 5.6L and 11L buckets suit larger batches on a typical installation. Do not mix more resin than can be used within the working time.

Do I need an extension handle?

A telescopic extension handle allows roller application across a large roof area without repeated repositioning, which speeds up the laminate stage and reduces the risk of resin gelling before the mat is fully wet out.

Are GRP roofing tools reusable?

Rollers and brushes contaminated with cured resin are not effectively reusable. Tools should be cleaned with acetone during the job while resin is still liquid. Roller sleeves are typically treated as single-use on larger roofs.
