Hmmm...I'm sure an expert will come along behind me,and give better advice...but...I am thinking that Liquid Nails should work.It's strong,just a thought.

Yep, I'd go to Lowe's or HD, whatever you have there. Go to the adhesive section and read the labels. Probably Liquid Nails would be a good one, I have actualy used it to place certain rocks exactly where I want them in the waterfall. Pretty good stuff, Comes in a tube like caulking, so you'll need a caulking gun to apply.

Thanks for the replies. I knew if I posted here I'd get some good advice. I'll be on the way probably this weekend.

mamaw2,

I had mine break into about 5! (darn squirrels!) I found the advice I took from this forum also, and it worked wonderfully. It is called "Plastic Fusion" and is a 2-part glue that you squeeze and both sides come out equally, and you mix it and apply. It dried a neutral blonde color and you can wipe the ooze off before it dries. My birdbath holds water, and you can barely tell it had cracked. I even filled in the chips with the glue. I found it at Home Depot. I have it right here "Fast-Set Plastic Fusion" - I've used it on tons of things since I bought it.

On a side note, on another tippy birdbath, I used Gorilla Glue and glued the top to the stem so it wouldn't tip. The Gorilla Glue foams and doubles in size to fill in everything - kind of like how "Great Stuff" works, but with glue. It wouldn't be good for your cracked birdbath because it would foam up, but it works on other things. You can actually chisel and chip the residue off it dries so hard.

Good luck with your project!
