Rated 3 out of 5 by from Poor adhesion to shed roof I bought this product based on brand and mostly good reviews to fix water seeping through the seams of the felt covering my pent shed roof. On a rare dry, bright day I painted the entire roof paying special attention to the joins. The roof was damp but the tin said that was ok, it went on really well and had a rain free night to dry. A few rainy days later several bare patches were evident and the seams still leaked. Perhaps it was just too cold for a water based product to dry properly so I wouldn’t count on this product for a winter repair.

Rated 4 out of 5 by from does the job you really need to make sure the surface is dry and you ideally need two coats to do a proper job. it needs six hours between coats, so a dry day is needed. having said all that, it does a great job of filling cracks and sealing a roof
