Shower - high walls and ceiling

[DPG]

I have a shower with a one piece insert that goes up to about 6 feet. Above that, we have 3 walls that are drywalled and papered (dumb, huh?) and a texured ceiling. The walls only extend about 10" above the insert walls. There is a fan in the dropped ceiling.

We want to tile the three walls and ceiling.

Two of the walls are sound - greenboard. The third is damaged from a leak in the shower head plumbing.

The textured ceiling is not rough, but is a smooth texture job.

How much of the backing do I need to change? Do I need to tear out all 3 greenboard walls and put in cement board? What about the ceiling? Do I need to tear it out? Or just sand it and seal it before putting up the tile (with Thinset)?

Thanks,

DPG

Hi DPG, you can go over the green board as long as it won't get wet same with the ceiling. Replace the damaged stuff though.

What about the ceiling drywall compound? If I sand it and seal it, will it suffice?

Yes , sand it, seal it with a good pva, then lick em' and stick em'

Hi DPG, Need to shorten that name a little, don't we?

I don't know what PVA is either, but it doesn't matter. I don't think you need it way up there. Just get the sheetrock smooth and use a good quality thin set to set your tiles.

Hey Mike,

What's PVA?

I think it stand for poly, vynil, acrylic. Anyway it's good stuff. John wouldn't it be better if the dw was sealed with some sort of primer or doesn't it matter?
