Painting Over The Mold

Glasshousebltr

We have spots of mold on a wall, I was thinking of just priming over without removal, however I don't want the mold to bleed through later. It's nut much mold, just spots.

Any input?

The stuff is alive. I've had a few painters say they could cover it but it always came back.

Best to treat/kill it then prime it and add M1 addative to your topcoat.

Killed it already.

I've never had luck treating the surface. I've found plenty of mold on the back side of the drywall alive and well after treating the front. I don't even try anymore. I just cut it out, bleach the studs, and replace it. I usually don't get spots of mold but sections of mold and there is usually some reason. (Like water). My experience is in a semi-arid climate and I may be missing something in the equations.

Kill the mold/mildew with one part bleach to 4 parts water mixture. Clean surface with a good cleaner like "prep rite" from Sherwin-Williams. Apply a high end stain sealer/primer and paint.

If it's dead then BIN it, I use it all the time to seal in dead mold/mildew that won't scrape off
Spots I'll use the rattle can BIN, in fact I don't leave home w/o it

But the mold/mildew must be dead, dead, dead.

Don't forget the mildewcide in your topcoat either. Is this a particularly moist room? If you don't do something to prevent it from coming back, I'm sure you know, it will.

Has anyone tried chlorine dioxide? A GC asked me if I did it and it was a new one on me. He said that they tent the house but a little Googling found topicals too. I disassociate myself from the stuff entirely. A clause from my contract reads,"The Contractor can not and will not be held responsible or liable for the presence of any fungi, algae, lichens, slime, mold, bacteria, wet or dry rot and any byproducts of these organisms however produced that may or may not be present now or at any time in the unforeseeable future.".

Time to clear out and call in the pros.

Next time you are renewing your ins., ask them about it. When you see how it hikes your premiums you will comprehend why it is a stand alone business.

I agree, just one look at myleakyhome.com will scare the **** out of a legit painter. Fl. is a step away from mandatory inspections and regulation of paint/coating film thickness. I use a sealer/primer for exterior that goes on blue and fades to clear after 3 days, leaves no question as to coverage and protection.
