Sooz...That's a beautiful piece. Being cement, it's heavy. You'll have to drill 2 holes on each side and insert 2 rods across the break to stabilize it. Lining up the holes will take a little skill. Do you own a drill? You can buy the metal rods @ Ace Hardware Store. Then epoxy glue on the cement break too....as an adherent. Let it set up for a day, then silicone across the top of the break so it will hold water. Your going to be able to see the crack after it's repaired, but once water is in it I think it will be a moot point.

you might try gorilla glue ... beware, it really expands

Thanks for the great info & directions, Nicole! Bragu, I happen to have some gorilla glue, & thanks for the reminder that it expands---I wonder if this bird bath's cement material is one of the materials where gorilla glue would work. Time to google! I have craft glue, that I know won't work, hot glue that I know won't work, gorilla glue and E2000 or whatever the number is.

I think Gorilla glue also. Super glue won't work, it'll just absorb into it.

Not sure if Gorilla glue is waterproof.

Thanks Olychick!

Gorilla glue does expand (like a foam) so if there's any way you can attach a clamp to tightly hold the broken piece in place it's recommended. Otherwise I'd use a good epoxy (the 2 tube/mix type) with some way to keep the pieces tight while it sets. With the irregular surfaces and the awkward shape a large rubber band might work best?

Sooz,

Gorilla glue is hard to control because it expands I would never use that on something that wants to fit tightly. My husband tried to use it to glue part of a porcelain china sink and it made a mess because it expanded.

Yeah I’ll crack lose called something like East 6000 and I’ll send you a link. I would find this more of a possibility. You can read about it. Think twice, glue once ;-)

I've used concrete crack filler and sealant to fill the gaps that the contractor left between the old steps and the new slab. It comes in a tube, like caulk. I don't think it would work to attach the broken piece (don't really know) but it would be a good sealant to top the repair. It isn't expensive, either.

You'll want to use a product safe for birds. Too bad it broke; it is so pretty. I hope you can fix it.

I used Gorilla glue to fix a large clay pot so this should work, you will need to bind the repair tightly to prevent the glue expansion from expanding the crack width. After gluing you can hide the repair by painting the entire bowl with a cement based slurry (water + elmers glue and Portland cement) with optional coloring added.

Maybe a two part epoxy glue. I glued a rearview mirror on my car back together that broke off and lasted for the rest of the life of the car 10 years. You can't use it in cold weather and you have to hold in place but it hardens really quickly.

Thank you everyone for ringing in here!

Smiles,

Sooz

Gorilla glue expands while setting and can make a mess although it may work. Quick set Krazy Glue types (cyanoacrylate) won't work. Those may grip initially, but will fail after exposure to water or moisture. I recommend 2-part epoxy adhesives. A low temperature resistant type should be fine; a higher temperature resistant epoxy may be more durable.

I've used Dap Platinum Patch. You would need to brace or support it until it sets, but it's very strong. https://www.dap.com/products-projects/product-categories/patch-repair/drywall-spackling/platinum-patch/
