    LESLIE: Pat in Iowa is on the line with a question about how to paint aluminum siding. What can we do for you today?

    PAT: Yes. I would like to paint aluminum siding on my home. I can’t afford to side it right now and I was wondering if it’s possible to paint aluminum siding.

    TOM: Absolutely, you can paint your aluminum siding. What you want to do is clean the house really well, power-wash it perhaps. And then you’re going to have to prime the aluminum siding. That’s really important.

    LESLIE: Otherwise, nothing is going to stick.

    TOM: Exactly. So you need to do a primer coat to paint aluminum siding.

    PAT: OK. Well, what kind of primer?

    TOM: Well, you’re going to use a primer that’s designed to work with the paint that you select.

    So, for example, if you’re going to work with the Benjamin Moore family of paints, you’re going to use a Benjamin Moore primer.

    PAT: OK.

    TOM: And the primer is the glue; it’s the adhesive coat. That’s what makes the paint stick. And then you put the topcoat on top of that.

    PAT: Now, will this peel on the south side where the sun hits?

    TOM: No, not if you do a good job on the prep. You know, that’s why we’re telling you to prime it. And because the siding is metal, that paint job should last you a good 8 to 10 years. Less if it’s an organic material, like wood siding. But with metal siding, it can last a long time if it’s done well.

    PAT: Oh, good. That’s a good thing to know. OK. I wasn’t sure I could even do it. I thought maybe it would just peel right off.

    Now, the power wash, is that with – I’d have to hire somebody to probably do that.

    TOM: Yeah, unless you happen to have your own pressure washer, yeah, you’d have to hire somebody to do that. And they’ll use a detergent and clean off any dirt and debris and algae and so on that’s on the metal. Then you let it dry really, really well. Then you prime, then you paint.

    I mean it’s a big project to paint aluminum siding, Pat. If you’re not comfortable with 10-foot and 20-foot ladders, depending on how high your house is, you might want to hire a painter to do this.

    PAT: No, I’d probably hire someone else to do it but do you think it’d be real expensive? Or would I be better off to find a good vinyl-siding man to put …?

    TOM: Well, I think that you don’t have to side the house. You don’t have to put siding. You can paint this house and paint it successfully and I think it will be less expensive than siding.

    PAT: Thank you very much. I appreciate it.
