paint for moldy walls

post #1 of 4
Thread Starter 

Our bathroom has a wall and ceiling mold problem.  Our home is wood heated, so the bathroom off the master bedroom is too far away from the stove to easily dry out.  We put in a more powerful fan with a heat lamp, and I hope that will address the source of the problem.  However, we still have to deal with the moldy walls and ceiling.  Do I need to use a paint with a fungicide?  I'd like to use a no or low-voc paint if possible.   Is there something I should prep the walls with before I paint?   I'd just like to be as non-toxic as possible.  Thanks for any ideas...

I used to live in Humboldt, almost right on the beach and we had mold all the flipping time - or well, the start of mold. The best cure was staying on top of it. Prevention is best because once mold hits it's hard to take care of. To fight mold you can make a homemade mold and mildew remover and use it. Fill a small reusable spray bottle with two cups of water and three drops of pure organic tea tree essential oil. Every once in a while spray down your walls with this solution and wipe dry. This mixture fights stains, but better yet the natural antispetic qualities of tea tree oil fight mold and mildew.

IF it’s too late and mold is rampant, you can try to get rid of it using more chemicals (which sucks, but you don’t want mold because of the health effects). Check out the CDC guide to mold for more ideas.

American Clay
has a mold resistant covering and their colors are gorgeous - it's not paint exactly, but it is eco-friendly clay covering and some independent tests show that clay plaster does not allow for mold growth on the plaster surface.

The fan is a good idea. No matter what, even if you get super mold resistant paint, it's not going to be a match for excessive moisture. I'd use the fan, keep the door open when you shower, and wipe down the walls frequently with a non-toxic mold fighter.

You can look for eco-friendly paint at the following links...

I used to have this problem in my previous home. The short-term cure was 2 or 3 cleanings with 100% household bleach (nasty enough stuff). This killed the mould for a year or so. 

The long-term cure was to lower the ceiling immediately above the shower by 8", insulating the newly created airspace. This eliminated the high temperature gradient that exists in winter. The new ceiling was surfaced with green-rock, a moisture tolerant type of gyprock for wet-areas, The result looked good & was a permanent fix.

Adding extra attic insulation directly above the bath would have a similar effect, but this wasn't possible for me.
