I'm trying to find a way of disguising the concrete blocks within a pond. The only pond paints which I can find are two-pot epoxy, specifically for stopping leaks, but my needs are purely cosmetic.
Do any of you know if ordinary masonry paint might have a harmful effect on plants or fish?
There are 2-pack epoxy paints for concrete floors. They're not always for leakproofing, Aqua.
I would have thought that good old Dulux Weathershield masonry paint would be enough. Also, I've used "parlour paints" in milking parlours. I don't know if they are fish-friendly, but the cows don't seem to mind ;o)
Thanks to all of you.
Paul, the pond is lined, but the concrete blocks are inside the liner. The need is to disguise them without poisoning plants or fish.
The general consensus seems to be that ordinary masonry paint will be OK.
