@johnthemoldguy: Time and time again we see that trapping moisture in a concrete slab that’s trying to release its vapor can lead to mold growth underneath, and no matter how old the slab is. #linoleum #sheetvinyl #basements #flooring #moisture
My contractor put LVP down in my house over concrete with no vapor barrier. He said the floor didn’t require it. I live in phoenix so not a lot of humidity but should I be concerned that there’s no moisture barrier?

So what type of floor would you use?

Nice find, I've found mold under vapor barriers too here in FL😅 I always recommend tile over any other type of flooring other than polished concrete. Any other recommendation?

You’d be surprised how many carriers deny removal of flooring because there’s “no visible damage”. But moisture is trapped below due to a leak. They don’t realize the floor has to be removed. It’s so frustrating

Bro, if that’s all the mold you get after decades then you’re fine

I sealed my concrete using a boba product and then a vapor barrier under my LVP. Thoughts?

Wouldn’t tile and paint block the ability for the slab to breathe?

We just converted a 3 season room and did Lvp over concrete with a vapor barrier and this has been on my mind. Not sure what can be done! We installed a dehumidifier

We lowered the slab in basement, replaced sewage pipes & repoured concrete for new bathroom. What type of floor would be best - ceramic?
