Mold behind paint?

Michael Derose · SoftWash Systems Certified Applicator

Does it look black? And did you use sh in your mix or just green wash and water?

The pic below is an example of what I was talking about in my first post. We also noticed after cleaning all the window frames today that there mold appears to be beneath the surface of the chalking along the sill of every window. We soft washed all the wood today and had to brush every inch of it. It took 2 applications. The first application made it look better, but it wasn't clean. After the second application, we had to brush it - all of it.

Here's another thing that's weird about this place; the HO was telling me today that 3 of his perfectly healthy trees suddenly died over the past few months and a 4th tree is currently dying. Several branches on it have already died.

That looks like a older window sill that has been painted many times with oil base paint

Schall,

The 1st pic I posted (above) is part of the soffit and I had the camera zoomed all the way in from 3 or 4ft away.

The windows of the home were all replaced about 3 years ago and the chalking around them has never been painted. As another test, today I fired up the hot water skid and hit a spot with 150 degree water at about 600psi and got as close to the paint as I dared without melting it. It didn't even phase the stuff. This was a 1st for me. I've never seen mold that could withstand heat and pressure.

Snapped a few more pics before I rolled out of there today.

You may want to suggest to the homeowner, in regard to the tree blight, that he (or you) take some sample cuttings from the dying tree to the local "extension office" to see if they can identify what is causing the trees to die. This may help you determine if you can kill it where it is attacking the house - if it is the same cause. You may even want to take a paint chip from the house with you to see if they can determine if they are the same agent. If so, they may be able to steer you toward something that may save the trees and the woodwork. biggrin

Mark, I may be able to get a sample off the tree, but the house is clean now lol!

Awesome Baby!! I'd still advise taking a sample of a dying cutting of the tree to either an extension office or Southern States Co-op (if they have them there), or any certified nurseryman who is qualified to ID horticultural blights. This way you'll know exactly how to treat it with "ease" the next time you run into it.

Good luck, just hope it doesn't spread up here!! wink

I would have guessed that it was mold painted over after a poor prep job but it seems you have debunked that already.
