birdbath - to seal or not to seal
I have a birdbath that I believe is cast colored terracotta. It has that familiar terracotta sound when I tap on it and it has a design on it, so I know it was cast in a mold. It also is a light cream color and the color goes all the way through. So, I'm ready to start glueing stuff on, but don't know if I should do something to it first (after a good cleaning of course). I read that you can glue right on it, that porous is a good thing. But then I read that some people seal terracotta first before attaching shards. I do know not to use Weldbond. Or, I guess I could cover it with a thin coat of thinset. So, what should I do? Of course, I want to get to the fun part and am hoping it's okay to just go ahead and start attaching. I'll be using thinset for that.
