Clean Mold from Wooden Shingles

  • Transcript

    LESLIE: So, Ron in Rhode Island, you call us about a problem but you’re doing a home improvement project right now?

    RON: Yes, I am.

    LESLIE: Yeah? What are you working on?

    RON: We’re painting the bathroom.

    TOM: Okay.

    RON: And I … this is the third time I painted it with … we have like a peach colored shower stall and fixtures – toilet and sink – and not a hell of a lot will go with it. It was … it was like a peach color on the walls and we wanted to change it. We painted it a light gray, then we went to a light green and now we’re going to white and I don’t know.

    TOM: Okay. And the problem is this paint continues to grow mold?

    RON: No, no, no, no, no. That’s another problem.

    LESLIE: No, he’s just painting. He’s doing home improvement projects.

    TOM: Oh, okay.

    LESLIE: And asking home improvement questions.

    RON: (overlapping voices) And also we have a white house with wooden shingles. And I’m getting this black mold … you know, little round spots in different areas. And I was wondering what would be good to get rid of it.

    TOM: Bleach.

    RON: Bleach?

    TOM: Bleach. Yeah.

    LESLIE: Yeah, a bleach and water mixture.

    TOM: Yeah. What you want to do is mix … do a bleach and water mixture; probably – I would say – probably at least one part bleach – maybe two parts – to five parts water. And then you spray that down and you let it sit for a while so it kills the mold. And then you could clean it off. Now, with wood siding, you don’t want to use a lot of pressure but you can use a pressure washer; that’s an option. Now, you mentioned that it was spotting. That might be something called artillery fungus. And that’s, traditionally, very, very difficult to get off. Have you put fresh mold – excuse me – fresh mulch around the house?

    RON: No.

    TOM: Okay.

    LESLIE: Because that would be (inaudible) …

    RON: As a matter of fact, you know, last spring I did it with, I guess, the pressure washer and I did it with bleach and also I put hydrogen peroxide in there. And my wife says maybe TSP.

    TOM: Well, better be careful, this chemical cocktail that you’re mixing up there. (chuckling)

    RON: Oh, it’s outside, though.

    TOM: No, all you need is really bleach. Bleach is a great mildicide. There’s one other product that I could suggest and that’s called Jomax – J-o-m-a-x. It’s really a house-wash material. And you mix it up with bleach and it helps the bleach actually last a little bit longer. It’s made by the Zinsser company. So you could give that a try, as well, the next time.

    RON: Where could I get that?

    TOM: Oh, any hardware store or home center has that. It’s a very, very commonly available product.

    RON: Okay.

    TOM: Also good for taking moss off of roofs. Okay, Ron?

    RON: Very good.

    TOM: Thanks so much for calling us at 1-888-MONEY-PIT.
