Project - Almost done?

[VToutdoors]

A quick question.

Recently had a contractor install backerboard, mesh tape, thinset, and then drywall around it, top included, feathering the joint compound onto the backboard. This is for a tub surround. His plan was to then cover the joint compound with hydroband, then thinset and tile.

Good or bad?

MAPEI, I believe GoBoard requires a urethane sealant, not Silicone. Our first issue was he wanted to put the board directly on the tub deck, I got him to accept 1/16th of an inch. He was planning on setting the tile directly on the tub decking, no gap.

He finished the outside corner with corner bead, the joint compounded over that

Its really unfortunate. He is one of the "preferred" installers for the local tile supply store.

At 5' height plus the height of the tub, it may be okay for the drywall above it...industry standards want the walls to be not damaged by moisture up to at least the height of the showerhead. But, that also assumes the rest was installed properly, which appears it was not.

If he didn't want to correct his mistakes, and you are in charge of the job.....you did perfect. If i am paying i am the boss. Stop the damage before the tile went up! Sure something might be fine in the industry, but shortcuts in the end will fail. I like to do the job myself because I know I will take the time to properly address an issue rather than work around it. If I were you, I would spend money on a good tile saw and do the work yourself. Not too difficult. knowledge is the key.https://www.schluter.com/schluter-us...roofing/c/SS-W
Good videos here to get that knowledge.

Who knows if it would ever cause a problem but I wouldn't risk it. Figure out where the tile edge will be at the paint and draw a plumb line. Then scrape off all the bed mud from the tile side of the line. Wet it and scrape some more until it's gone. If you need to feather the surface over there, do it with thinset.

Davy,
Thank you for the response. Thats what I was thinking.

Right you are, they do require Polyurethane sealant, my bad.

Spoke with the Contractor today. In his opinion, everything he has done was to industry standards.

Have him show you in the TCNA manual where these methods are listed, after all that is what he will have to do when he gets to court.

Trying to figure out the best way to transition from HardiBacker to Drywall on the same plane with metal trim (Blanke/Schluter bar).

- Hide the transition seam under the metal trim with about 1/4" drywall. If so how do you deal with HardiBacker not being 1/2" thick?

- Try to hide the transition at the edge of the metal trim?

Theought of using the Drywall's tapered edge, but don't really like that idea

Hi Adam,

Can you remove the corner bead from the drywall and then tile beyond it?

[rmckee84]

Mesh tape and thinset the seam, and feather the joint by slightly building up on the cbu side. Hide the seam under the last tile.
Or shim out the wall where the cbu will be so that it will be flush with the drywall. Its still a good idea to mesh tape that joint.

[VToutdoors]

Currently there is no corner bead in place.

I decided that Im going to hide the transition 1/4" under the metal trim/last tile. Will definitely be using mesh tape, and plan to feather the joint by slightly building up on the cbu side.

thanks guys

So in your drawing, the hardibacker (gray) is 7/16" and the drywall (green) is 1/2 inch?

If so, I would use some drywall shims and shim the hardibacker out. A lot of times you'll need to do this anyway when flattening the wall prior to installing backerboard.

Then mesh tape that seam and run the tile past that joint. Finish with metal trim.

This has probably been answered a few times and Ive read a few threads on this topic but hoping someone can offer a little advice

Hardiebacker to Drywall transition.

Hardiebacker wall is flat, shimmed, Im very happy. Drywall unfortunately is not.
The transition from my Hardiebacker to drywall varies from 1/16th" to 1/8th".

The 1/8th" transition seems to be in the middle of the wall.

I plan to feather thinset with mesh tape over the transition. When done tiling Ill finish up with joint compound on the drywall, prime, paint, chalk the seam.

Can you shave down the Drywall a little? It would remove the drywall paper facing. Good or bad idea?
