What's your opinion on this white-ish mold like looking stuff, mold or dust?

Some kind of white fungi. Easily nuked with a light mist of BoraCare.

Mike, do you have any familiarity with Concrobium?

Have you ever heard of or is it even possible to cold fog Boracare?

Hey Chris,
We use couple hundred gallons of Concrobium every year. I like it better than BoroCare. Cost more, easy to fog or mist or wet spary. Non-toxic, but stinks to high heaven when fogged.

Seems this may be a good application of the product.

I've been recommending Concrobium for several years now. The stuff appears to actually work. Funny though whenever I get a chance to ask any of our local mold remediators, they've never heard of it.

It's sold here locally in the rental department of Home Depot where they rent the cold foggers.

Hi,

Don't know if you can cold fog BoraCare. A 5 gallon pump sprayer with a deft touch should do it though (it'll be a bitch to keep agitated).

Isn't concrobium that white stuff that looks like Kilz? If it's clear when applied, I'd say go for it; but I wouldn't use it if it looks like everything is coated with Kilz when done 'cuz it screams "toxic mold" in the minds of lots of home buyers and inspector folk who don't know any better.

OT - OF!!!

goes on clear and dries clear. it does leave a fine powder residue on the fogger after running a couple of gallons through it.

We have found most "mold control" products are pigmented. Close and careful reading of specs show most to be a covering or barrier.

Looks just like mold/fungal material to me too; it looks like there are rusted staples on the sheathing, indicating humidity issues in the attic. Is there really a need to spray anything on there once moisture issues are addressed?

That's a good question. When it's winter time, I can measure the moisture content of the decking and come to a determination as to whether I think there is an ongoing issue, but if it's summer, I have no idea if there's an on going issue.

Also, it depends on the weather that day. On a cool cloudy day in the spring, the decking moisture content could read high, but if it's a sunny day and the decking is heated up, the moisture content will read lower, sometimes much lower, but the humidity in the attic will be high.
