Acetone

Acetone is a cleaning solvent that is used to clean the GRP Roofing resins from the consolidating rollers, laminating rollers and brushes so that they can be reused.

Bubble Busters

Also known as consolidating rollers and paddle rollers, these are made for the fibreglass roofing market and reduce splashback and air entrapment when working the Base Resin system into the fibreglass reinforcement.

Catalyst

Sometimes called an activator or hardener, a Catalyst is a chemical that is mixed into the GRP Roofing Resins and Topcoats to accelerate the curing time. The product comes in three different speeds to either increase or decrease cure speed for optimum performance in different temperatures.

Catalyst Dispenser

The Catalyst Dispenser has been specifically designed for safely measuring and dispensing Catalysts into mixing buckets with the GRP Roofing Resins and Topcoats.

CSM

CSM stands for chopped strand matting and is the fibreglass reinforcement that is used with the GRP Roofing base resin system to reinforce the roof giving it strength. For more information on Fibreglass reinforcements and the different variations, check the Fibreglass Matting Guide.

Consolidating

Consolidating and laminating is the process of bonding the glass fibre to the OSB decking by applying the fibreglass reinforcement to the decking and rolling it with a consolidating roller. This breaks down the binder of the fibreglass and gets any air out of the surface.

Laminating

The laminate refers to the surface created when the GRP Roofing Resin bonds to the chopped strand matting and is fully cured.

Green Trimming

Green trimming is the process of tidying up the fibreglass reinforcement around the trims and corner section usually with a retractable knife when the main laminate is cured but not solid.

Pot Life

The amount of working time you have with the catalysed GRP Roofing Resins and Topcoats before it starts to cure. Pot life will vary depending on temperature and the amount of Catalyst added.

Wetting Out

To reach full strength the Chopped Strand Matting in the GRP Roof should be fully saturated with the Base Resin System. When the glass fibre reaches this stage it's called wetting out.

Binder

Chopped strand matting is made up of tiny strands of glass bonded by an emulsion binder which breaks down when the Polyester GRP Roofing Resin is applied. Binders will vary from different manufactures and some will break down quicker than others.

Delamination

A term used to describe what happens when the main GRP Roofing membrane comes away from the decking underneath.

Exotherm

An exothermic reaction is a chemical reaction that releases energy and heat. The GRP Roofing Resins when activated with Catalyst will generate heat by the polymerisation process and will become noticeably hotter.
