EverbuildEvercryl One Coat Instant Waterproofing – Suitable for Roofs, Gutters and Gulleys – Grey – 1kg

Bought this to repair a leaking gutter connection seal and it has so far worked a treat. It's thick and sticky, so stir before use and apply with an old brush. Rained a couple of days later and no dripping to be seen, after a month or so still holding up. Great for a quick and simple sealing of joints or small holes.

Really solid product - saved me a lot of £££, I DIY'd it instead of paying someone to do it. Really easy.

This is good 'stuff' used it before but unfortunately the tin lid had sprung despite the extra clips used and some of the content had leaked into the plastic bag of which it was enclosed thankfully. I had left the package, unopened, in my lounge. Heaven knows what damage may have been done was it not for the plastic bag. Anyway this is a good product and does what it says on the tin.

Excellent product, does exactly what you would want it to do.Sticks to pretty much anything

I'd previously used flashband on flat roof cracks and other repairs. There was quite a bit of messing about and it never felt like a lasting solution.This stuff is great!Easy to apply, goes on nice and thick, easy to work in tricky places (where flashband would be impossible), and can go onto all sorts of surfaces.Many leaks now repaired with this, and all seem to be lasting well.

I used Everbuild Evercryl One Coat to fix a leaking roof valley, and it exceeded my expectations. The product was super easy to apply straight out of the tin — no mixing, no fuss. It went on smoothly and sealed the area immediately.Within hours, the leak was completely gone, even after some heavy rain. The fibre-reinforced formula seems really durable, and I love that it doesn’t require a primer or dry conditions to work.Highly recommended if you need a quick, effective fix for roof leaks. Definitely keeping a tub of this on hand for future emergencies.

Appears to be working

Used to fix a leaky patch on my flat roof. It has worked in the short term, but I have noticed the dried coat is very easy to crack. However, after applying 5 coats and the crack propagation has pretty much stopped. Good value for money in my eyes. Make sure to mix well and be sure to apply a few coats.
