underlayment in a 30 year old house bathroom. Owners originally had PB with ceramic on it & seemed to hold up well for 20 yrs. Then tore out tile, installed padded vinyl sheet good. Then carpeted over it. BUT they now are DETERMINEDto put ceramic back over the PB underlayment. Due to monetary restrictions & the impossibility of raising the finished height with backerboard. What is in your opinion the best way to proceed?
All opinions seem to point to using ARDEX X7G Plus thinset. Consensus being that this is a great product & that the german(european made) cements are superior to those mfd here (?) What are your opinions/comments on this dilemma? :bonk:

If they are planning on paying you for this, pass on the job.

I'll let Frank be Frank with you. :lol2: I just did a job that they had glue down carpet on PB. I tore it out and it came out in crumbs. The stuff is junk. Remove it or forget about the job.

Hi Frank
Even if the German engineered polymer modified super thinset is actually
better than what we have here, which i doubt because all the big companies
are international..... The partical board is still about as close to bonding
tile to dirt as your gonna get. If they insist on leaving it, head for the door.
This kind of installation is trouble down the road. Best of luck.

I'll be Frank, Musky, Jim, and Jack with you. It's not in your best interest to try to proceed with this. This is a well understood problem that you can't tip-toe around with a different mortar.

If you can't install the job correctly, you aren't giving them value for their money.
