Hi Amy, I feel that your tile prep will be just fine as is. The mortar that was there withstood chipping the old tile off its face so that should count for something in regards to its integrity. Adding more mortar just to add it seems like a bad idea and is unecessary.
I've yet to see an installer use an expansion joint for the waterline tile but if you feel you must have one, it could be as simple as using a polyurethane caulk in the corners instead of grout. It doesn't need to be much more complex than that.
Thank you Brian!! Do you think we need expansion joints where the planes of the tiled bench/steps/tiled wall meet? Shouldn't expansion joints be cut into the mortar - then filled with caulk?
Many thanks again. I've been in a panic for 24 hours, as I wasn't here yesterday when the work was done and decisions were made without me!
THANK YOU -
Amy
