Removing Black Mold From Our Bathroom

As detailed at http://drywallinfo.com/drywall-mold-removal.html despite repeated cleaning with bleach, mold kept coming back. This video gives an overview of how I corrected the situation to remove the mold and prevent future mold. As a side benefit, I reduced my heating costs as well.

Did you use tape on the seams of the foam boards?

[msakowski]

@celia222 For foam boards with no gap I used duct tape. For gaps in between and along edges I used a bit of expanding foam from a can. You should seal up the gaps as good as possible to prevent moisture and cold air from getting through. If you leave a gap for cold to get through, that will be a place where moisture will condense on your finished ceiling.

Sometimes it's not a good idea to seal everything up like that. What if moisture gets behind your plastic? What you did makes sense but sometimes it creates more problems. Just a thought, I liked your video.

@gregvancom The vapor barrier was only over the wall insulation. If moisture gets beyond this (and very little will), it will easily escape through the exterior sheathing. There was no plastic placed over the dense foam on the ceiling as this was a barrier itself. And ceiling moisture can also easily escape.

You make a good point though. Never seal in moisture with a vapor barrier on the exterior of the insulation. This was not done here - the barrier was on the inside of the insulation.

Or just shower with the door open so the humidity wont feed the mold, its pretty simple

So you just taught me how to spend a bunch of money on a professional

Fit an extractor fan for the hold air to escape

I had mold just like that many times. I used California kitchen and bath paint. Mold never came back. its been 12 years.

Yes very helpful video. We have a mold problem in our bathroom too right now, we have no wall insulation and can't afford to sort this all out -- it's a nightmare.
