I'm ready to tackle my new shower. Right now I've got 6 by stud walls and
insulation (no sheetrock). I'm putting up 1/2 backerboard then tile. Do I
need to put some sort of waterproof layer under the backerboard, such as
plastic sheeting, or can the backerboard be screwed directly to the studs? I'm
sure this has been addressed before, but-- any compelling reason to chose
concrete backerboard over Hardiebacker?
6X? Is that 2X6 studs?
There's not enough detail in your post to give you any specific advice.
Stall shower? Tub shower? Plastic shower pan? Tile shower pan?
I will say this, you should at least have drywall behind the tile board
to stiffen it and give it density. Tile does not flex well. If you
bump into that flimsy wall between the studs you'll see what I mean.
you have got to be kidding me AnnG (drywall behind the tile board)
and you have the nerve to correct others in here.
get back in the field and out from behind your desk!
>Tile does not flex well.
just like walking on a floor where the backerboard does NOT land on a joist.
right AnnG...................that's what I thought.
My comment regarding placing the stuff over drywall (for stiffness)
stands. As for a vapor barrier? I recommend you find the mfger online
and read their faq's or specs regarding
that. But think about it. The stuff is bascially water proof or at the
very least extremely water resistant so why would you need a vapor
barrier behind it on an exterior wall? Because it's in a shower? What
are you trying to protect?
No offense to you but unlike the novice we never use any of them for
walls or countertops because we use mortar and in most instances set
over freshly placed mortar to allow as nearly perfect as possible a
level, plumb and even set, free of swales, rises, and lippage between
If it's an exterior wall, you should insulate and put some sort of vapor
barrier to keep moisture from migrating toward the outside and damaging
paint on the siding. I've used cement backer board (1/2") behind two shower
stalls in my house, tiled over it, and it solid. This stuff is not
flexible---especially when screwed down every six inches on a 16" center
Honestly, drywall, then cement board is overkill.
