Did the job demanded of it.

It does literally what it claims to do on the tin. The relentless storms and ceaseless rain afflicting North Wales in February 2020 caused a significant and extensive leak in an upstairs room due to the stone chimney stack above it acting as a sponge. One spray of the Leak Stop Sealant prevented any further ingress of water into the room and the repair appears to be permanent. Because it is a spray it is very searching and can reach concealed target areas. I have not tried any of the many other similar products from other manufacturers and assume that they all work upon the same chemical formula.Read full review
