No More Back-Breaking Multiple Layers Or Money Wasted On Unnecessary Materials
Moisture Cure outperforms most other rubbers by giving you a highly durable watertight seal in a single no-fuss application.

Perfect for weatherproofing fibreglass roofs for years to come.

Application is easy.

1) Completely clean and dry the roof and use a biocide such as ISO A-Clean.

2) Measure and mark out the roof to get the correct coverage. This ensures you have the right amount of material for the area. Take the coverage rate and work out how much your roof size, or each section of your roof will need. Alternatively, if you have a one gallon of Moisture Cure, you can mark out 4-5m², depending on the roughness of your surface.

3) Mix in the catalyst.

4) Pour onto roof and use a squeegee to distribute the material. Follow this with a roller to get a smooth and even finish.

5) Sit back and enjoy the confidence that comes with a Moisture Cure rubber roof.
