My contractor uses SHEETROCK® Drywall Joint Tape to tape outside the
shower stall and a "classic" fiberglass mesh joint tape FibaTape inside
While the latter is mold-resistant, is it still good only for outside
of the shower stall, and a more advanced FibaTape Mold-X10 should be
Or would it be years (if ever) until I see the difference?
A good portion of the shower stall is lined with cement board but some
"less exposed" ones areas are lined with Sheetrock, like the rest of
the bathroom. But I am wondering if using a paper-based tape anywhere
in the bathroom is a good idea, especially on the untiled (painted)
wall on the side of the sink?
I decided to post my question here after the contractor said there is
no point to set the max temperature limitation on the valve. It was a
red flag to me.

I didn't set the max temp for either of my 2 showers. My "kids" are
old enough that scolding is not a concern and I don't want to be
limited to a certain range for those times when I'm trying to eke the
last drop of hot water out of my tank.
Just like asking him *why* he's using 2 different types of tape, did
you ask him *why* he said there was no point is setting the max temp
on the valve? If he has a valid reason, then maybe you can lower that
Maybe, but probably not. Some use paper tape everywhere. Use a
quality kitchen/bathroom primer and paint with mildewcide added and
you will be good to go 20 years provided your bath has adequate
He is doing it right..
If you wanted a mold resistant room you could/should have requested
paperless sheetrock , mold resistant mest tape and USG Durabond and Easysand
Joint Compound for the whole room UP FRONT...Mold really doesn't like the
setting type compounds for some reason....The ENTIRE wall gets mudded like
you'ld do when plastering because the the sheetrock has a fiberglass face
and is VERY rough....It isVERY expensive and I've only done it a few times
all of which were indoor spas or lap pool rooms...In short your being a
PITA..... ; ) .....Use your exhaust fan and you will be fine...Opening the
window helps as well...
The tape used is the least factor to be concerned with. Is he using FibaTape
Mold-x10 over drywall in the shower? OR is he using it over cement board?
My personal opinion, after seeing so many problems and failures, is that any
gypsum based product, even if it is rated for shower use, will probably fail
or cause problems in time.
The OP already said the shower is CEMENT board with mesh tape....It's the
use of paper tape in the rest of the bathroom he is concerned about molding
for some reason that's beyond me , given the sheetrock is covered with
paper....The contractor is doing it right....
