Kerdi Over Painted Sheetrock?

Hello-

We're doing a remodel of our bathroom. The sheetrock got put up and finished Thursday. My dear wife was so excited to see progress, that she felt she had to paint the walls.

No knowing for sure where the shower tile edges would be, she painted the whole shower corner!

The big question. Is that okay? Can I put Kerdi over painted sheetrock? Please don't tell I have to take it out and replace it. Please.

Has anyone sucessfully Kerdied over painted sheetrock? Help!

If the paint is thoroughly dried, I would sand it with some 150 grit sandpaper. Others might recommend a primer over the paint.

I agree that thin set over painted walls works fine.....but. Is it cured yet? No way. I normally want new paint to cure for a few weeks. Also, is it just paint? Didn't she seal the new drywall first with a primer/sealer? I think you need to wait. OR, if it's just a corner, you can try sanding with 60 or 80.

The high alkalinity of the thinset is harsh for fresh paint. If you install the Kerdi, the fresh paint is going to be in a high alkaline environment for quite a while before it's all dried out...and that's not a good thing. That would very likely weaken the bond to the drywall.

But it's fresh paint and won't take long to correct it with this idea that worked for me in a similar situation. Suit up with a dust mask and eye protection, then use a random orbital sander with some 60 grit paper to remove the paint. Keep the sander moving...it won't take long to buzz through the fresh paint. The paper face will be a bit fuzzy when you're done, but it will be fairly clean and intact.

Hi Larry,

Krud Kutter will clean fresh latex paint off drywall right down to the paper. You might want to give it a shot in a small area to see how the work compares to the other suggestions here.

Wow.

Thanks for the quick replies.

Yes, there was a primer sealer put on first.

Because this project is DIY and not moving very fast, I think I'll let it dry/cure for a couple weeks, then rough it up with 60 or 100 grit.

I have to be out of town until the first anyway. And then I need to build the half wall. In the meantime, I've still got some elctrical to finish and get the heat mat ordered...

You know how it is. Enjoy the weekend. It'll be near 90 in Iowa today.
