Rated 5 out of 5 by from In the shed again. Five star great product well done Screwfix I would definitely recommend.

Rated 4 out of 5 by from Does What Its Says On The Tin I guess that sums it up really. I used it to repair a garage congregated asbestos roof. It applied easily and seemed to go a fair way. Haven't given 5 stars as yet as I need time to see it maintains the water seal. Not too messy to use and cleaned up any mess using turps. Being Grey its also a little less obvious its been applied than the standard black repair sealant.

Rated 1 out of 5 by from misleading description Front of the tin says use on WET or DRY surfaces. Back of tin says ensure surfaces are DRY Which is it - handed back for a refund

Rated 5 out of 5 by from Great Roof Repair Had cracks and small holes in my shed's felt roof and this stuff did the trick at repairing them and making the roof watertight again. Not a permanent solution, but it'll last until I can get the shed re-felted in the summer. I can't 5 star the performance or reliability because I've just put it on.

Is there any preparation of the roofing surface required? (the existing roof contains embedded gravel as part of the original installation)

Asked by: Anonymous
Thank you for your recent enquiry. We would always recommend removing the embedded gravel to ensure a full and complete waterproof coating is achieved. You will need to remove the gravel, patch any required areas then prime with a bitumen based primer before proceeding with our Roof Repair Compound. I hope this information helps.

Can this product be just to seal cracks in corrugated roofing?

Asked by: Mattash86
The Cementone Roof Repair Compound Grey is a solvent based fibre reinforced acrylic roof coating designed for application to roof surfaces such as bitumen, asphalt, roof felt, concrete , wood and metalwork. In general the product can be applied to a corrugated roof assuming it made of one of the above materials, but it is not suitable for use on polycarbonate or GRP. The product is intended to be applied as an overall roof coating but could be used in localised areas for hairline or small cracks. However, for larger cracks, the use of a scrim reinforcement such as fleece which is a thin cloth material normally used for protecting plants from frost is recommended. This should be cut to size and applied into the wet applied product, then immediately apply more product over the top.

What is the life expectancy of this product .

I am looking for something to seal the joints (2x 30cm) between a flat fibreglass roof and the lead run-offs. As its my own roof and its 3 stories up I dont want to be doing it again in a few years.

Thank you for your recent enquiry relating to our product. Regrettably I have to advise that none of our roofing products are recommended for application on to a Fibreglass surface. As Fibreglass is already waterproof our products will not adhere to the surface. I trust this helps.

would this be suitable for asbestos corrigated roof?

30sq meters how much would I need ?
Asked by: redmond
The Cementone Roof Repair Compound Grey 1 Kg is a fibre reinforced acrylic waterproof roofing product that is designed for application to various roof surfaces including bitumen, asphalt, roof felt, concrete and asbestos cement. The product needs to be applied at a rate of 1 to 2 kg per m², the coverage for the product can vary depending on how rough or smooth the surface is that it is applied to. Also, consideration will need to be given that with corrugation, the actual surface area to be covered will be greater than for the same area for a flat roof. In general, only one coat is required.

Can I use this on fiberglass?

Asked by: retasueandbob2
Thank you for your recent enquiry relating to our product. Unfortunately I have to advise that none of our roof waterproofing products including our Roof Repair Compound are suitable for fibreglass surfaces. As Fibreglass is already a waterproof surface the roof repair compound is unable to 'wet out' on the surface. Please accept my apologies that I am unable to offer you a product from our range on this occasion.
