Nassboards - Everbuild Evercryl One Coat Repair Compound - 5 Litre Black- Fibre Reinforced Sealant for Roof Reparation - Algae and Fungus Resistant, One Coat Roof Repair - Multi Use & Weather Proof

After heavy rain in February I noticed the garage floor was wet. I looked up and saw the plyboard was soaking wet which meant I had a hole in the felt.I couldn't find a hole, the felt was in good condition and around 15years old, neighbours cat does get up there and scratch it's claws into the felt though...I bought this product and applied it while the felt was dry during a break in the bad weather. I brushed it on a large area around the leak, also along the nearby joining seams. Easy to apply, wear old clothes and the supplied gloves as it seems to get everywhere!Being winter it wasn't warm enough to dry out the boarding so it concerned me that maybe it was still leaking but there were no drips on the floor, eventually after a few weeks the sun started shining and it all dried out. Been raining lightly since and no problems. It's now May and we had really heavy rain last night so I cautiously opened the garage door this morning and it's dry.I've still got half a can left, I might give it another coat in the summer months when it's warm and dry.Will update this review if I ever do get a leak in the same place

I had some dampness on the felt roof of my 8’x6’ shed and I could not detect the leak. I was not keen on replacing the felt roof, particular in November! A neighbour recommended Evercryl as he had used it previously and found it easy to use and it resolved the leak problem. I also read reviews and the majority were very positive. I purchased 5kg of the grey colour as I was not sure how far it would spread. It was easy to apply and left a satisfactory finish. It has resolved the leak and I am happy with the result.There was also enough left to apply to my other 6’x4’ shed roof and I am more than happy with the results.

I thought that it was a bit runny which meant that it dropped when bridging small gaps. Not my favourite

Very happy great value for the product and arrived super fast

Easy to apply, but at 0.75 sq metre per kg coverage I required approximately 40kg to cover a 29 square metre flat roof, much more than expected. Using a brush it was necessary to apply 2 coats to get the recommended coverage.

Packaged really good. Used on roof and impressed that the leak has been fixed. Also really fast delivery. Great.

Used it to repair flat roof easy to use.And it seals well

I used to be in the specialist coating field and found this an application friendly product onto an exisiting polymer coating, it took no time to coat a flat roof and coverage was 100%. Only applied one coat in damp conditions and it's holding its own. BUT how long should I need to wait until I consider a recoat, hence my three stars.
