Great product - easy to apply
A water based product made it very easy to apply and meant absolutely no strong chemical fumes were present. It is a mid/dark grey when wet, but drys a much darker colour grey, almost black. This clever colour change indicates clearly when it has dried. Used for applying to a shed roof where the existing felt had cracked and some moisture was beginning to seep through. Coverage was exactly as stated on the tin, although it might vary from quoted amount depending on absorbency of surface. It dried in around 6 hours and withstood heavy rain 10 hours after application. I now much prefer to use this to traditional bitumen based products. Cleaning up brushes afterwards was easy using soapy water.

I tried this product rather than replace the whole roof covering, applied the seal to all the joints. It rained overnight and the following day, no signs of water penetration therefore can only state that the product does exactly what it states. How long for ?
