Forgive the slightly unusual topic, but I'm wondering if anyone on the list
has any expertise in how to safely seal an existing in-ground concrete
birdbath. I made it out of Sakrete sand mix, and it's been very popular
with the birds, but it's a bit too porous and loses water due to seepage.
I probably should have built it with a liner, but now I'm trying to figure
out a way to seal it without starting over.
Sakrete makes a "cure and seal" product, which is a water-based acrylic
that would probably do an adequate job. But the manufacturer was unable to
advise me as to whether or not this would be safe enough for the birds
(i.e. will it leach into standing water, and if so, would it be toxic?). I
know there is a safe epoxy-based product out there called Pond Armor, but
it's very expensive.
I'd appreciate any advice anyone has! Off-list may be more appropriate for
this one.
