Review on 🦍 Gorilla Waterproof Patch - Liquid Ounces: Tapes, Adhesives & Sealants by Shalom Germann

For large cracks I used Lexel flexible sealant. Then I could use Gorilla as the top layer since it's not as expensive as Lexel. I used both of these products on a bridge over a goldfish pond. All the boards rotted because the builder did not use durable wood. I replaced everything with suitable wood and filled the gaps with both products depending on the gap width. The Gorilla product didn't seem to like exposure to air as it split into two separate components rather than being fully layered that didn't easily fuse back into something more homogeneous. Knock but nothing to stop me from buying and using it again.
