Product Information
Full details
The Cromar PRO GRP Roofing Kit is an all-in-one solution designed for professional roofers and experienced DIY enthusiasts tasked with installing a high-quality 52-square-metre fibreglass roof. It provides a comprehensive suite of resins, topcoats, reinforcements, and essential application tools to ensure a seamless, watertight finish. While the kit offers significant convenience by bundling every necessary component for a project of this scale, it requires a solid understanding of GRP application techniques and safety handling for chemicals to achieve a successful installation.

FAQs
Does this kit include instructions for mixing ratios?
Yes, always refer to the specific technical data sheets provided on the product packaging for the precise catalyst-to-resin ratio based on the temperature.
Can I use this kit if it's raining?
No, GRP application must be performed in dry conditions. Rain or high humidity will prevent the resin from curing properly.
Are the tools reusable?
The brushes and rollers can be cleaned with appropriate solvents, but heavy residue may make them difficult to reuse for subsequent jobs.
How do I ensure the roof is watertight?
Properly overlap the fiberglass matting and use the trim adhesive on all edges and flashing to create a seamless, continuous barrier.
Is the ProGRP top coat UV resistant?
Yes, the provided top coat is designed specifically to provide a durable, UV-resistant, and weather-tight finish for roofs.
What should I do if I spill resin?
Clean up spills immediately using a suitable solvent and absorbent rags before the resin starts to cure.
Troubleshooting
Resin is curing too quickly.
The ambient temperature is likely too high or you have added too much catalyst. Mix smaller batches in cooler conditions.
Air bubbles appearing under the fiberglass.
Use the bubblebuster rollers more aggressively immediately after applying the resin to work air out of the matting.
Top coat remains tacky.
This is often caused by insufficient catalyst or low ambient temperatures during the curing process.
Pros and Cons
Pros
- Eliminates the need to source individual components separately.
- Specifically calibrated for 52 square metre projects, reducing material wastage.
- Includes professional-grade bubblebuster rollers for a high-quality finish.
- Provides ample mixing and measuring equipment for large-scale application.
Cons
- Requires professional-level skill to apply evenly without pooling.
- Catalyst and resin have limited working times once mixed, requiring fast application.
- Substantial storage space required for the bulk liquid components.
- Not suitable for users without personal protective equipment (PPE).
Setup, Compatibility & Care
To begin, ensure your roof deck is clean, dry, and free of debris, as GRP will not adhere to damp or dusty surfaces. Store all resin and top coat containers in a cool, dry, well-ventilated area away from direct sunlight. When mixing, always add the catalyst to the resin at the manufacturer's recommended ratio. Always wear protective gloves, goggles, and a respiratory mask, as both the catalyst and resin emit fumes during the mixing and curing process. Clean all rollers and brushes immediately after use with an appropriate solvent to extend their service life, although some items may be intended for single-project use.
