Minor mold/mildew issue?

I’d cover it if it was mine. No sense in inhaling any mold spores if it can be helped.

I work in Disaster Relief. This is not my area but I know we buy a product at Home Depot I believe. We dilute it according to the directions and spray it under in and on people’s homes. I think we pay about $20 a gallon for it and you dilute it. I don’t know if you can get smaller quantities or not. I think the can says it is good for 20 years. If you could buy a smaller qty then it would be a great find. We used to use 10% chlorine bleach solutions but found this to be better and not as offensive.

I would clean it off with a light bleach and soap.
Then blow dry it off.
And then seal it with zinnser bin, which is a shellac primer. It will seal the wood, and you’ll stop looking at that OSB :-)

Shellac is a better sealer than Kilz IMHO.

bleach is more dangerous than mold, leave it alone.

Agree with Snipes.

I just read an article on Removing Mold. They also Cautioned on Using Bleach. DON’T!

Hi ADHDan,

You could try this a 1/4 of a teaspoon of oil of clovers in a 1 litre spray bottle.
Just spray a mist of it over the mould or mildew that will kill it. Wait a few days
than wash it off with white vinegar. That is the recipe for all mould & mildew.
I hope that helps. Let me know if it works. That is what I use here in Australia.

Cheers Graham.

Thanks all for the advice. After considering it all I’m leaning towards this plan: spray it down with a non-bleach, non-ammonia mold control spray like this: http://www.homedepot.com/p/Concrobium-32-oz-Mold-Control-025326/100654126, let it dry and scrub/repeat per instructions, and keep an eye out for any darkening/spreading patches down the road. If it looks like the problem returns, I’ll spray it again, wait and wipe with vinegar, and then paint with oil-based Killz.

Does that sound like a reasonable plan? I have extremely limited time right now so even if the spray just delays the problem for a while (and I eventually have to do a bit more work), that’s fine with me.
