I'm looking for a waterproofing sealer that I can apply to the mortar on my waterfall. I'm having a hard time finding something that says it can be used in underwater applications. Any ideas?

Thanks, I'll do that.

It's definitely a possibility if I can't make the plaster work. I'd rather have plaster though. If it turns out to be way too much work then I might go the liner route. Thanks

I've posted some pictures now. Please let me know what you think.

I'll have pics in a few hours. I'm waiting for a friend to bring me a camera later today. I'm guessing it was a pond, they had a waterwall on it. They didn't have a pond liner so I guess they used plaster. It hasn't had water in it for a long time either.

I need to resurface a 25yr old pond in my backyard. It was constructed with bricks and mortar for the shape and then coated with what I think to be plaster. The plaster has developed many cracks and bare spots over the years and it needs another coat. How should I prep the surface before...
