Oops...managed to knock the head off venus de milo bird bath base and also the top bath broke in 2 pieces whilst cutting customers lawn. Have watched a few youtube clips etc.
Anyone done a similar repair.?
Putting the head back on seems simple enough..possibly a dowel and some gripfill I already have. The bird bath bit is more delicate.join pieces about an inch thick which has then got to hold the weight of half the bath.
Alternatively cast a new top ..but that sounds not too easy

Hippo pro3 might do it,sticks anything to anything and is waterproof

Gripfill, then epoxy putty for finish maybe

Epoxy, also for finishing off mix loads of the stone dust (from drilling) with clear epoxy as a filler. You need to brush the stone thoroughly to get rid of any loose stuff, you can't glue dust to dust. If you can peg it all the better, or even drill some small holes to give something for the epoxy to grip into, any increase in surface area helps to make it stronger.

Make sure you have enough epoxy to hand, mix it very thoroughly, you only have one shot, figure out how you are going to hold it together first.

I'd be tempted to use standard epoxy, takes a longer time to set but if things start going wrong fast-epoxy limits your recovery chances.

Gripfill, stixall, hippo etc may well work but epoxy has got a long track record, its even used to hold rock walls together (together with pins).
