Butyl liner repair
Used on a repair to a damaged butyl liner at the edge of a very large pond, to seal a few large holes then to stick a patch over the top. Worked very well. Will definitely use again if needed.

Very messy
Very messy and very difficult to get off your hands. It will stick to anything it touches permanently so make sure you are wearing old clothes. I wish there was a warning about this on the product.

😊
Fitted pond window using it, had 6 tubes only need 4 to fit the glass window so far works great, fined it slow drying so have to do it in layers to get a full seal all the way around.
