Rated 4 out of 5 by from Easy to apply I use the seal on my lead flashing. It looks neat and is easy to apply and is long lasting. I am happy with the product.

Rated 5 out of 5 by from Best I’ve used Having got an elderly, problematic flat roof, I’ve tried a lot of repair products over the last few years when different sections begin to leak. This is the best I’ve used, in every way: easiest to apply, easiest to clean up, looks the best, and works the best. I recently had water gushing in during heavy rain. I picked a dry day, and applied this (first time I’d used it). It needs 6 hours to dry, but within 20 minutes of finishing a single coat the rain bucketed down from out of the blue, and I was furious. But... IT HELD. I don’t know how. Later inspection proved it’d barely been affected by the rain, and a second coat sorted any little issues out just fine. I love that it’s grey going on but dries to black. It doesn’t smell bad at all. It covers really well and spreads more easily than bitumen based coatings. It’s straightforward to clean up with water (and some scrubbing), and it gives a lovely neat appearance when it dries. The only think I can’t comment on is the longevity, but if it can take that much rain before even drying I have high hopes.

Rated 5 out of 5 by from Great product and good price We have now bought 3 tins of this roof paint. It covers well, drys quickly and keeps out the serious rain we have in the south west. Add to that it looks great

Rated 5 out of 5 by from Thompson Roof Seal Read a lot of info on the most reliable paint on sealer for gutters, flashing etc and plumbed for this. Must say I am more than pleased, Painted on easily, dried in 6hrs so it can be redone on the same day. Coverage good, slapped it on thickly and it has sealed all that needed doing on the flashing and roof. Brushes clean out in soapy water, a plus and the painted areas look a treat now that they have dried. Just waiting for the first heavy downpour to see that it has worked. I believe it will as looks like a rubber sheet now.
