You guys are much more experienced than me. I'm used to painting everything with one shot....but of course that's no longer smart. I just finished a panel, aluminum laminate. I scuffed it well and sprayed two coats of Dunn Edwards Latex Acrylic (so it sez). It scratches off easily, as I found out in installation. I waited several days before installing it so that it would cure. I'm the central valley of Cali and I don't see Matthews anywhere. What do I switch to? I thought Acrylic was the superior resin? Is there some kind of additive to harden waterbase? Help...

If it was a factory painted aluminum panel, I have had best success with exterior acrylics by doing a thorough scuffing of the surface with 120 or so grit. 220 and finer like for enamels doesn't give enough tooth for the thicker acrylic paint. YMMV

What I would do is visit your local Sherwin-Williams paint store. They might set you onto the right direction for the best paint for the job. As few years back, there was some cement silos here painted. The paint company used Cloverdale Industrial Coatings, Self-Prime Speed Enamel 76002c. I think it is a sold at Sherwin Williams. But why didn't ya just roll it out with 1-Shot mixed with 1-Shot hardener?

Si; Good to hear from you. This is a commercial aluminum/styrene panel and is painted...(or powder-coated?) from the store (Denco). John; I scuffed with a red scuff pad. I would have used something rougher but the scratches seem to come through. Senorita Ali; Yeah well, I have had such bad experience with the one shots of late. Seems like I always get a can meexed on Friday...or Mondays. Too much something (not oil) that makes the color thin and streaky...or chunky. Ronan seems far more like the paint of old but the cost usually prohibits using for background. Remember I live in the furnace not the garden room like you.

Are you referring to aluminum composite material? Different brands have different finishes. We use white MaxMetal from Grimco. We scuff the surface with scotch type pads and spray or roll acrylic latex DTM (direct to metal)paint. This type of paint cures very slowly - 30 days, but you can handle it well enough to install after a few days.

I too, use MaxMetal. I scuff and paint with Frazee Mirro-Glide. Frazee is now part of Sherwinn Williams. I can't scratch it off after 24 hrs if I scuff good.

SW seems to have discontinued both Frazee and Richards lines. Website has some SW brand enamels. Still looking for suggestions.... Cloverdale doesn't come up either.

Cloverdale and RIchards come up in a straight search but not how they are distributed. Richards is in Florida and Cloverdale in Wash/Org area. I'll just have to talk to the local stores, I guess.

Paint scratching off easily comes from one of tow things and this goes for just about any kind of paint. 1. it's an adhesion problem, not scuffed, not etched, surface contaminated, powder coat with silicone additive, leaving plastic protective on, etc. 2. Paint isn't fully cured. Letter something in 1 Shot on Monday and Tuesday it will scratch off pretty easily, by Friday it won't budge. Latex can be the same way. Wait a few weeks and go back and see if it still scratches off easily.

Acrylic and acrylic-latex is not the same, the latter is "PVCenforced", which is cheaper and comes off in large flakes and do stink. Allways use 100 % Acryl, nothing better, keeps color and last for more then 15 years, cures fast, no solvent fumes, brushes washes completly clean with water/warm water.

I have sample panels coming from independent paint store and SW local. They have several products, some water based and some oil. We'll see, I gave em a each a piece of alumacore. Neither had a quick answer but both used the DTM anagram as if it was a magic word. Sad to see where the industry has sunk to.
