Hi, I see this great post: www.aquarium-pond-answers.com/2007/03/aquarium-silicone.html . I want to make sure that I'm understanding the appropriate substance to use for my case. I have a large, concrete birdbath that has a large chunk missing, as well as various hairline cracks. It appears to be simple cement reinforced with rubber wires; it has maybe a glaze on the top of it working as a sealer. I want to see if I can seal the exposed concrete from the missing chunk, with a layer of glue or something similar to glaze. I'd like to reinforce the hairline cracks with something like superglue. I don't know if the cracks make the birdbath leak. These materials will be underwater and exposed to freezing temperatures. I want them to be non-toxic for food use for birds as well as other animals. I don't know if I can picture a caulk-like substance for this purpose. If that is not the correct product, I wonder if there is a glue aquarists use for gluing ornaments. What kinds of product(s) would you recommend? As a side-note, I'd like to do this right, but I want to keep it very cheap. The alternative is buying a new birdbath bowl. Thanks for the help.

Hi Birds; There are epoxy products for gluing ornaments under water such as the "AquaStik Coralline Red Epoxy Putty " www.americanaquariumproducts.com/TwoLittleFishies.html#aquastikSilicone can seal Concrete and slightly expand & contract too. As well the concrete itself can be sealed with a two part epoxy marine resin or similar product. Carl

Thank you, Carl.
Does that putty end up working like a glue like superglue? I have JB Waterweld but that doesn't seem to work as a glue.
Does the silicone apply like a glue or is it more like rubber?
Do you happen to know the name of two-part epoxy, offhand?

The putty is not like super glue, more like a clay glue Silicone is best applied with a caulking gun and is more like a thin to thick rubber (depending as to how applied) Here is an article I wrote about its use: Silicone ApplicationsAs to the resin, no I do not know, it was two part resin meant for marine applications and is safe for use on boats etc that would be exposed to wildlife and thus non toxic. I've purchased it at Home Depot I will look around later and see if I can find a link Carl
