Paint question

Re: Paint question

Bill Tindall, E.Tn.

Read the directions on the can and see what it says. Call paint company tech service and ask. Or.....

Here is the problem with a generic answer. Latex paint formulations are complex and every company uses different ingredients. Ditto for what was used on the drip edge. Bottom line, there is no guarantee that what worked or didn't for someone will predict your performance.

Test. The problem will be adhesion if there is a problem. I have had exterior latex paint stick tenaciously to a metal surface, but you don't have a metal surface. You have a painted surface, painted with who knows what, probably a powder coating or which there are many formulations. The paint you intend to apply only cares about the coating it needs to stick to. Whether it is metal or wood beneath is irrelevant.

Put some of the proposed paint on the metal to be coated. Let it dry a week. Make a cross hatch scratch pattern. Add tape, pull off tape and see what kind of adhesion you observe.

Ellis, It doesn't seem like you would need "direct to metal paint" as your drip edge is already painted white. I've often painted over prepainted drip edge with latex paint to match the painted wood facias and soffits and its held up well.

Ditto on the paint store or calling the tech dept. of a paint company.

I flipped a house with aluminum siding that had failing worn out paint on it. Talked to a paint store (Sherwin Williams) and they said it's an excellent base for paint and sold my painter primer and paint. He sprayed it on and it looked great and is holding up well. Your problem might be trying to stick to the new slick surface, mine was old and rough. Double check, don't talk to the newbee.

Probably not much help but...

I know the metal roofs down where we have our river cottage are usually done with paint intended for metal roofing. I'm pretty sure it's not your normal paint off the shelf.

As mentioned, the problem to solve is what is the coating on the drip edge and what will adhere to it. Perhaps besides contacting a paint company or store you might also try to contact the manufacturer of the metal roof material to see if they have any guidance.

I did this and it worked

when I lived in WA I had a metal roof on our house. Is was painted before we bought it with a brown Rustolemun paint. I pressure washed it cleaned it and painted it over with a forest green rustolemun paint. I went by 5 years later and it still looked like the day I painted it. At the same time I painted an old metal shed that had never been painted with the same paint. It also still looked good as new. I sprayed it on.

I have had success with rust-oleum. The local Menards store had satin tintable base, so I brought in a piece of trim and they color matched it( Home Depot can probably do the same thing ). Because it is enamel oil base paint make sure that you put just enough to cover so that the paint is able to cure/dry all the way thru. If remember I used 6 of the cheap foam brushes (when the brush got a little ragged I tossed and got another) and that seemed to lay it on just right and smooth. I did it 8 years ago and still looks like the day I got done.

I have used this on cast iron, no primer, and it is excellent. It's available through Ben Moore dealers. I used the oil base version. I bought a quart can.

Yes, we'll test it

Ellis Walentine

Thanks, Bill. Yeah, this material is roll formed to order and curtain coated at the fabricator, so it's certainly some kind of powder coat. The surface has some tooth, so I was just wondering if latex might get enough of a bite.

Ellis

That's valuable, thanks

A paint store would be the next logical stop. Thanks Barry and Ralph.

Ellis

Seems like rustoleum is another answer

Ellis Walentine

I was hoping not to have to go to an oil-base, but it wouldn't be too tough. The fact that we can get a color match could seal the deal.

Thanks,

Ellis

Re: Rust Scat

Ellis Walentine

Good to know, Steve. I wonder how it works on galvanized steel. Anyhow, if it sticks that well to unprimed metal, it must be good stuff.

Thanks.

There should be a latex paint out there that will work for you. I used to repaint aluminum siding with what was Benjamin Moore's high end gloss exterior paint at the time. They told me it was specifically made to repaint aluminum siding. They don't make that product any more but they should have a replacement. The trick was getting the siding clean. It took a lot of power washing and scrubbing followed by slight roughing up with a scotch pad.

Use regular trim paint.

Steve D, CT

I misread your original post.

If you just want to match prepainted drip edge to your trim, you may be able to get by with a water based paint tinted to match. I just had my house redone and I am painting vinyl trim and gutters to match using PPG's exterior paint. I am getting good adhesion without primer but YMMV.

Someone already suggested a test. If it sticks you can skip primer.

Re: Use regular trim paint.

E Phillip Smith

Last year I painted gutters, down spouts and soffit vent on patio addition to porch with Sherwin Williams A100 exterior paint and it has held up well so far. I did clean with scotch brite pad with 409 first.

Thanks!

I've painted metal that was previously coated, with both rustoleum, no primer, and Behr exterior super white with or without a tint.

20 years ago I had to repair some vinyl siding, and they no longer made the color, so I had some color matched Behr, and painted over some white. It has never given way. Unfortunately there is divergence in the color over time. I also repaired a small hole with duck tape and painter it, like 20 years ago. It is still as good as when I made the "repair", and this spot is in shadow, and there has not been color divergence.

I also painted parts (about 50%) of my trimaran (wood epoxy) right over the original Awlgrip linear. The Behr is holding up better. Unbelievable stuff.

I don't get a lot of honey do pressure, so if I want to paint a swatch and let it season a few years nobody minds.

I have also heard great things about Sherwyn Williams, aluminum screen door paint. My pal switched over from the Behr to it to get another color. A lot of people swear by it for boats. And there are some hwy line paints, in white that are also super durable, and I have heard that big boxes in the US sell those.
