I have a large freshly dug pond. I put filter fabric down as a underlayment. The pond is about 4600 sq ft. I am using billboard tarp liners. Patched all holes with flex seal tape patches. The seams are 36 ft long. I am trying to use hh66 glue and its quite hard to do in the pond so i am also having trouble doing it in the yard . Anyone know a easy method of doing it right in the pond. Shelf life is 18 months on hh 66 vinal cement and mine is a bit older. Does not seem to be working well. I may need fresh glue. Quite a large job for one 67 year old man. Please send ideals
