What is suggested as a pond sealer? We just had a pool built and our pool guy had the gunite guys gunite the pond I dug. He was going to plaster it, but just getting him to finish my pool has been an ordeal and I don't want to deal with him any more than I have to so him doing the plaster is out.

I did seal it with a dry-loc type paint (home depot brand), but one part has chipped and it isn't even filled yet so I'm not comfortable with moving forward using only that. I read on another forum about using Thoroseal, but it doesn't seem to be readily available in any of my local stores and I'm not sure if t will adhear to the paint.

Suggestions would be greatly appreciated!
