Rated 5 out of 5 by from Well worth the money Bought this to repair a leaking garage roof. Very easy to apply, stair with a stick and use an oil paint brush to apply. Although quite expensive it really does fix leaks.

Rated 5 out of 5 by from Fantastic product Wanted a good dependable product that could be applied to wet surfaces - difficult to find. Made the purchase and had to ring technical Dept. for points of clarification - superb clear and concise replies. Used product - easy to apply plus it cured the leak All done from ordering online to completed job was 3 hours - how good is that ?

Can this be used on sloping shed roofs?

Asked by: Ady46
Yes, with a word of caution. I used it to try and fix my cabin which has shingle felt. Unfortunately despite using 15 lts on the roof, it is still leaking. I would say that this is good for a shed roof that already has felt rolled on it. i.e. a repair. I would not recommend for bare wood, or if you have shingle felt. It can bridge small gaps, but is not good enough to be relied on for bridging a lot of gaps. It is bitumen like product with small fibres in it.

We do not recommend the use of Flexacryl on Fiberglass or GRP as the product will not adhere to this particular substrate.

Dot and dab

Can you dot and dab Knauf moisture board onto this? I want to tidy up the interior side of a single skin outbuilding wall.
Asked by: iwb70
The Bostik Cementone Flexacryl Roof Repair Compound Grey is a solvent based, fibre reinforced acrylic roof coating designed for exterior applications to roofs constructed of roof felt, concrete, wood, metal and slate among others. Once applied it is waterproof and is intended to be the final finish. Consequently it is not suitable to dot & dab Knauf moisture board to it, or indeed to be used for interior applications.
