Product Information
Full details
The PRO GRP Roofing Kit is designed for professional contractors and experienced DIYers looking to achieve a seamless, high-performance, and watertight flat roof finish over a 13-square-meter area. This all-in-one system includes premium resins, top coats, fibre glass matting, and a comprehensive selection of application tools, providing everything needed for a durable, weather-resistant installation. While it offers unmatched structural integrity, users should note that the system requires careful adherence to mixing ratios and weather conditions to ensure proper curing and a high-quality finish.

FAQs
Can this kit be used for vertical surfaces?
Yes, but you must ensure that you apply the resin carefully to avoid sagging; work in smaller sections to maintain control.
How long does the resin take to cure?
Curing times vary based on temperature and the amount of catalyst used, but generally, the surface should be tack-free within a few hours.
Do I need to prime the roof surface before applying the kit?
The deck must be clean, dry, and free of debris. Ensure the substrate is compatible with GRP resins before starting.
What should I do if I spill resin?
Clean spills immediately with an appropriate solvent like acetone before the resin cures.
Are safety gloves provided in the kit?
The kit focuses on application and mixing tools; you should provide your own Personal Protective Equipment (PPE), including chemical-resistant gloves and eye protection.
Can I use the bubble-buster on the top coat layer?
No, bubble-buster rollers should only be used during the laminating stage while the fibreglass matting is being applied.
Troubleshooting
Resin remains tacky after several hours
Check if the catalyst-to-resin ratio was accurate. If it remains tacky, you may have used too little hardener or applied the layer too thinly; apply a thin layer of top coat after the surface has fully cured.
Excessive air bubbles appearing in the matting
Use the provided bubble-buster rollers more aggressively immediately after wetting out the matting to force the air out before the resin begins to gel.
Resin hardening too quickly in the bucket
You may have added too much catalyst or the ambient temperature is too high. Mix smaller batches at a time and work in a shaded area if possible.

Setup, Compatibility & Care
To set up for your project, organize your workspace to keep the 14-litre mixing bucket and resin containers on a level surface. Before starting, check the weather; GRP systems perform best in dry conditions, typically between 5°C and 25°C. Avoid application if rain is forecast.
Maintenance of the kit tools during the project is essential: keep a supply of acetone (not included) available to clean brushes and rollers immediately after use to prevent the resin from hardening on the equipment. Store all unused resin, top coat, and catalyst in a cool, dry place away from direct sunlight to maintain the chemical integrity of the products.
