Bostik Flexacryl Grey 5L is rated 4.9 out of 5 by 18.
Rated 5 out of 5 by from Fixed leaks immediately I bought this to waterproof my garage roof after storm Dennis ripped the felt. Great for patching small splits as well as painting over stacked areas. Simple to apply and good coverage. Highly recommended.
