Need suggestions on flooring for 2nd floor laundry room. It is part
of a big remodel, but we are finishing floors ourselves. In remodel
plumber put a drain in center of the floor (big laundry room, 12x18)
He also laid that thick shower floor membrane over entire floor. Now
we want to finish with ceramic tile. How do you put ceramic tile
over shower pan membrane? As it stands the membrane is just laying
on the plywood floor.
Pull up membrane, put down cement board, put membrane over cementboard
then put tile over membrane. Obvious problem is, does the thinset
bond to the membrane??
Could just put cement board over membrane, essentially rendering
membrane useless with all the screws through it.
Any other suggestions.. it is too big of room to put down "cement" or
cementlike covering over membrane, then tile on that like you would do
in a showerpan.
will not be attempting to slope floor to drain, too tough on such a
big floor, and water on floor would be very infrequent, it is just a
safety drain, so not worth sloping.
