Shimming metal stud walls

[Notadecor8ter]

I will be tiling my bathroom with porcelain 600x300's and focusing on the tilebacker at the moment.

First Issue is I've got about 5mm out on a plumbline on a first metal stud wall and im sure the rest will be with issues so how to solve?

I've thought about shimming with some plastic packers, will this be suitable and solid enough? OR do I have other options?

I’d level it off with some bonding then skim then tile

Mate says I can get away with higher runs of tile adhesive with what ive got.

Yeah you can. It’s the choice between ball aching the tiling or prepping the plaster so the tiling’s easy. Both are valid. I’d personally rather sort the wall and know I’m not going to come unstuck on the tiling. You can also mitigate it a bit by thinking about the corners which is probably where this is going to get noticed. Ie. Set out the tiles so you don’t have a small sliver in the corner against the non-plumb wall so you don’t make it so obvious to the eye…

Cheers, when you say bonding I take it you mean adhesive bond? This is a metal stud wall though ?

bonding coat plaster, after boarding, to get it bang on before skimming.

Edit: sorry, didn’t read your post properly, you’re doing backer boards, so shimming if it’s a full cut wood shim / firring with full contact to the board, or dubbing out the tile adhesive is your best bet if you can’t get away with the discrepancy visually. Ignore what I’ve said about bonding/skimming

That's fine mate, it's not easy with the variation now days.

I'm getting a level ish on the vial when I put the spirit vertically, that vial reading was what worried me.

Next worry is should I see any movement after screwing on 20mm Tilebacker (XPS)

Sounds like you’re all good really if it’s just about plumb. The fact it’s larger tiles is going to be more forgiving than small ones where a cut down a slightly off-plumb edge is more obvious to the eye.

If it's only 5mm out over the entire wall I wouldn't worry; you'll be able to take that out with adhesive. Use a levelling system too

Make sure it's the wall and not your level
