I'm working on a sandblasted HDU foam sign that has a picture of an island scene. I want to use bright blues, greens, with blends and bright fire red. This sign will get heavy u.v. exposure in Florida. Once this sign is installed I won't be able to go back and repaint it since it's going up high (would have to rent a bucket truck). One Shot paint (or alkyd) fades too quickly; I would like to use a water base paint. I am figuring on using sponges to blend the colors. Any suggestions on what is the best paint to use?

Jean , I sure hate to burst your bubble but if you think 1-Shot will fade quickly, don't even attempt to use water-based paint. Water based even with a clear-coat will have a much shorter life span in the hot Florida sun. I suggest you re-think your stratagy and possibly use the 1-Shot with their #4007 hardender as an additive at between 10 and 20%. Do not add any reducers to the paint and make sure that the paint is mixed well in the can before pouring it into your cup then adding the hardener. If you still aren't comfortable with my suggestion a clear-coat of Palucid or Frog Juice might just give you the assurance needed.

Not to question Joey, but I thought one of the reasons people were switching to waterbased paint was due to the fading factor (and health reasons)?

Joey, Thanks for your input. I have used latex house paints for sign backgrounds and have found that they don't oxidize like alkyd paints - they don't get that chalky film after a couple of years. I'm a little hesitant about clear coating even though I've read wonderful things about Pelucid. I even bought a can of it about a year ago but haven't used it.

Randy, the signmakers primary concern is to make sure their sign lasts. To be health conscious is good but I believe its up to the individual to protect themselves from the hazards of certain solvents and materials which all paints have whether water based or solvent based. From what I understand Deka water based paints soon will no longer be with us for whatever reason.
There are many different ways to protect yourself from these contaminants in paints which are always airborne whether it be a respirator or latex gloves. But first off, you must learn to use the proper tools and materials for your projects.

Companies (automakers, larger manufacturing facilities, etc.) are switching to waterbased paints because the EPA is forcing them to for environmental reasons.
Smaller companies are using waterbased paints because they *think* the paints are safer but they really arent.
Anything airborne is bad for your lungs, but consider this.. Your body is mostly water. Your body absorbs water very readily. Wouldnt it make sense that your body will also absorb chemicals, pigments, etc. that are encapsulated in water, and absorb them at a very high rate? How about your lungs when you spray waterbased paints?
Waterbased paints are getting better but you still cant beat automotive paints for longevity, durability and UV resistance.

Jean, I too have found that waterbased acrylic paints like Sherwin Williams DTM and Sherwin Williams "Woodscapes" solid color stains hold up better than OneShot and alkyds which tend to fade and chalk quite rapidly here. The pelucid might just cure the problem though. You might consider Createx airbrush colors for that fade. Just a suggestion.

I apologize, I think my post was misleading. I meant to say that's why the topic of waterbased was brought up before. Someone mentioned health issues. And after discussion, everyone came to the conclusion that protection is always needed.
I understand that every chemical has it's downfalls, and protection is always in order.
My post was questioning the fading of waterbased paints. It was also stated in previous posts that shops were switching to waterbased paints because some of the signs were holding over 10 years strong. And the oil-based paints had a tendency to chaulk and fade?
So when I saw it in Joey's thread the other way (oil outlasting waterbase), it threw me for a bit.
I hope I cleared up my typing error. I'm not trying to bring up any health issues.

Jean, I would use the Ben Moore house paints for the background, 1-Shot for the graphics and clearcoat with 2 light coats and one final heavy coat of POR-15 PELUCID. Kinda pricey for a clearcoat, BUT, you will not have to recoat for years to come !
