Durock placed along tub install


I dd not silicone the underside of the tub onto the 2x4's underneath the tub.
The wallboard(durock) is placed over the tiling flange and curves towards the tub as it laps over the tiling flange causing flat-wall issues when it comes to tiling the wall. I'm thinking of cutting the durock along the flange on 1 side, the long side, silicone and then tile accordingly. However since I did not silicone the underneath don't know what to expect.
Should have done this research In advance. I'm seeking advice to remedy my problem to save my project. I have manage to remodel the entire bathroom and now this hickup. I'm in the tiling phase of the shower when I noticed this mistake. Thanks in advance

I will be doing that once I'm at that stage. However I was asking if I cut the durock along the flange to correct the flat wall issues from your opinion do you foresee a problem.
Thanks again.

Durrock should not be installed over the tub flange---backer rests on top of the tub flange---resulting gap is filled with thinset as the tile is installed---

No silicone is used in the installation of a tub or the Durrock--

Mesh and mud the seams and corners as you set the tile

There would be silicone used at the tile to tub gap once the tile is set, not grout.

I think the OP should remove the Durorock at the overlap and shim it some so the Durorock can overlap the tub flange.

Second guys you do not grout to the tub you silicone it.

Durrock does not overlap the tub flange---set rock to the top of the flange---fill the gap with thinset as you tile---I think I said that already---

Yep--Been a member for years---lots of lousy info over there ---any body seems to have an option rather than expertise---then the place is reduced to arguments--

Who would drop the rock to the top of the tub? It causes a bent sheet of rock--if the entire wall is shimmed (furred) then the Backer board/drywall seam doesn't mate up---

So an experienced installer sets the rock to the top of the tub flange---

and fills the resulting gap with thinset as the tile is installed---or before if the walls are waterproofed before tiling.

Durock placed along tub install


Do you think that becasue my nic is referencing my previous occupation?

It referees to a point in time. Now I have installed many a piece of durorock and have read the instructions in how to install around a tub or enclosures. now be a good boy and go read the directions.

Second you never ever use grout to the tub. It will crack and with your method of leaving the durorock above the tub, allow water to penetrate behind into the wall ans onto the floor.

www.usg.com/.../installation.../durock-cement-board-installation-gui.

Now if you don't like that, how about tub instructions?
www.efaucets.com/.../pdf/bathtub%20installation%20instructions.pdf

Now I can't open PDF,s on this computer but trust me it is in there.

As to pictures, none handy of how to install.

as to your question of how to install without shimming the whole wall, my preference is to nail paint stir sticks approx 6 inches in length to the studs before installing the durorock'

now as to your final BS, I am 58 years old and until I was injured a few years ago spent little time online, unlike yourself. i worked and had a life.

Just become someone has many more posts does not mean you are correct. in fact, I joined a few years ago and quit because of the BS that was being spread. may have to quit again as a moderator should have more sense than to question someone and put them down with the BS you have used.

By the way, the John Brides forum is considered by people who actually work in the trades and want to make themselves better frequent. If you persist in inaccurate instructions again I implore you to visit and take to heart some of the posters guides.

If that is to much to ask, frequent the Contractortalk site, the sister forum to this one.

Your links didn't work---shimming with a paint stick would throw the rock out of plane--the popular tiles of today 12x12 and larger require a flat wall--1/8 in 10 feet--or lippage will occur--

And a bulge will rise where the shirt meets the top---how do you address that ?

Durock placed along tub install


i have done it both ways and it is an opinion on which way is best but all cement board manufacturer to my knowledge recommend a 1/4" space between tub deck and board and i always waterproof membrane paint all walls full height of tile, or membrane it schluter kerdi system but it is more costly

john bridge is a recommended site by the tile association but just like this sight it is full off opinions and some i agree with and some i do not due to my experience in the field because what i have seen during repairs and remodels one thing i highly do not recommend is putting plastic up over vapor barrier insulation before cement board due to the amount of mold growth i have seen becuase of moister trapping between the two off them if you fill the need for that extra precaution use a breathable moisture barrier like roof felt or house wrap
