Cool, thanks for the info. And to answer your question, "no end currently in sight."
Another question: We have a baby grand piano in this room that's being tiled. The only easy way to work around this that we thought of is to tile all the room except where the piano sits, wait the proper curing time, move the piano to a finished part of the room, and complete the floor where the piano formerly sat. I know it will be a nerve-wrenching experience setting the piano on the finished tile for the first time. The piano sits on 3 legs, on small wheels. What precautions should we take? Any better ideas than what we've come up with?
