Fastfix Wet Shield Roof Repair Compound
Fastfix Wet Shield is a resin based, fibre reinforced roof repair compound that is effective on all common roofing surfaces, creating an instant waterproof seal when applied, even in wet conditions. Because there is no risk of wash-off, it can tackle emergency leaks without waiting for the rain to stop. It is brush applied and dries to a smooth, seamless and flexible membrane that resists algae and fungal growth, and the high level of fibre reinforcement lets it bridge small cracks with only one application.

Frequently Asked Questions
Can it really be applied in the rain?
Yes. The resin based formula creates an instant waterproof seal and there is no risk of wash-off, so you can apply it during rain to stop an emergency leak without waiting for the weather to clear.
How is it applied?
It is brush applied. Clean the area as best you can, brush on a coat of Wet Shield, and it dries to a smooth, seamless, flexible membrane over the leak.
Will it bridge a crack?
Yes. The high level of fibre reinforcement lets it bridge small cracks with a single application, which is what makes it a practical repair for hairline cracks in roofs and gutters.
Can I paint over it?
Yes. It comes in grey and can be painted with an outdoor paint once fully dried, so the repair can be blended with the surrounding roof colour.
