FAQs
Does the kit include enough material for a 39sqm roof?
Yes, the kit is specifically curated with 60kg of resin, 60kg of top coat, and the necessary matting to cover a 39sqm area.
Can I use this kit in cold weather?
GRP resin is temperature-sensitive. It is generally recommended to apply between 5°C and 25°C. Consult the specific resin data sheet for winter catalyst recommendations.
Are the mixing buckets reusable?
The buckets are provided for the project; however, cleaning resin out of buckets is difficult. It is best to treat them as single-use or plan to clean them immediately while the resin is wet.
What type of deck should I install this on?
This kit is designed for use on new, dry, moisture-resistant roofing grade OSB3 boards.
How do I ensure the correct ratio of catalyst?
Use the provided catalyst dispenser bottles and graduated buckets to measure the resin volume and catalyst drops precisely according to the ambient temperature guidelines.
Troubleshooting
Resin setting too quickly
Reduce the amount of catalyst added to the mix or work in a cooler area away from direct sunlight.
Air bubbles trapped in laminate
Use the provided bubblebuster rollers firmly across the surface while the resin is still wet to release trapped air.
Resin not curing fully
Check that the catalyst-to-resin ratio is correct and ensure the ambient temperature is within the manufacturer's specified range.
Pros and Cons

- High-grade resin and top coat designed for long-term weather resistance

Setup, Compatibility & Care
Proper setup starts with safety equipment, including gloves and eye protection, as working with resins can be messy and irritating to the skin. Compatibility is optimized for clean, moisture-free oriented strand board (OSB3) decking. During the curing process, ensure the area is protected from sudden rain showers or extreme heat, as these can ruin the finish of the top coat. For long-term care, the cured GRP roof requires minimal maintenance, typically only needing an occasional wash with a mild detergent to remove grime and debris buildup.
