Plywood Mildew


Built a doghouse with a friend and there is BC plywood on the inside of it. This is what it looked like about two weeks ago.

Up until last week we had a lot of rain. I donít know if moisture in the air is the cause of this or not. There was a scrap of plywood and that was put in the shed and it looks the same.

Any thoughts or anything to do? We can paint it if that would help. Sheís just not keen on the dogs hanging out in there with the mildew all over the plywood.

Re: Plywood Mildew


dry it out good, heater/fan both...

treat with mildewcide from big box store, it works

paint with kilz....

then do a color coat and let the dogs pick the color...

Re: Plywood Mildew


So basically the plywood can mildew, but paint isn't going to and that's pretty much all there is to it?

Re: Plywood Mildew


you have to kill the spores on the plywood then encapsulate them.

Re: Plywood Mildew


It is a large problem here as well, I keep some plywood in a shed and that got some mildew on it just like yours. I placed it in the sun and it was fine.

Many schools here have mold issues this year after being closed up all summer, the humidity has been very high for a very long time. The schools close for weeks while they are cleaned

Re: Plywood Mildew


Is there a vapor barrier under the shed, and/or does water pool under it?

Paint with mildewicide doesn't mildew quickly.
