I have to re- paint a series of canvases for the windows of this grocery store with a new design. The example is one of 16 three panel windows (big job). They are all separate hanging canvases with sewn edges and Loops at the top to hang with horizontal dowels. I can order, cut, and have sewn the canvases. My problem is I am not sure what kind of paint to use so it does not fade in the sunlight. The current banners are 4 years old, and do not show signs of fading, or cracking. As of right now, I cannot find any information on how it was done the first time. Ideally, house paint would be great, because that is what I have used for indoor murals, and its cheap. Any advice would be much appreciated.

almost all paint will fade in direct sunlight,.... uv rays decompose the color and for the most part it will appear lighter,....the only sure way to get around this is to use paint that is made with permanent pigments,..pigments are chemical colors that have been oxidized and or predecomposed to the point there is no more chemical breakdown possible so there is no way they can basically fade,...the problem here is that most of the permanent colors and pigments are classified by our govt. as poisonous and or a threat to our environment. The chemistry of paint (unchanged for the most part for over 600 years) has been changed to meet our govt. standards to the point that there are no such paints available to you as an artist,.... thus almost any paint you use will fade over a period of time when exposed to direct sunlight. there are several uv resistant coatings for sale out there but there are no inexpensive paints out there that will last when exposed to direct sunlight,....be prepared to spend extra for paint if you want a coating that will last,..and it will not come from any major brand name paint manufacturer that you will recognize from mainstream media advertising;as it is not in their best interest to sell a permanent product(planned obsolescence to guarantee continual sales).

If those are the colors, they are basically earth tones and you will not see that much fading as with reds or oranges. Latex will hold up the best, but you might try using best quality artists acrylics, instead? http://www.gamblincolors.com/ Gamblin certainly claims to have the good stuff and I have been very pleased with their quality before, but have never tested them for san fading. Ask them?

Tim sez: "the problem here is that most of the permanent colors and pigments are classified by our govt. as poisonous and or a threat to our environment." That's news to me. My oils palette is made up exclusively of Winsor-Newton traditional permanent colors and the only one I know that's classified as poisonous or a threat to the environment is the Lead White.

Dennis the problem is that most mural work needs more volume of paint than comes in the small tubes that winsor and newton or any other brand of artist's paint for that matter and Ryan was looking for an inexpensive paint to buy,...the point I was trying to make is that fifteen years ago sign paint was using these same permanent pigments and now they are not allowed to use them in a manufacturing process thus our govt. circumventing the variance they put forth for artists and making any practical volume of paints available to us as sign and mural artists for large work to be produced in an economical manner as it has been in the past.
edited to add,.... there was a time when we would buy our oil paints like you suggest in quarts and gallons before the govt. made it impossible for the paint manufacturers to produce them in the United States. This made economical artists pigments in any type of volume very very expensive for the average customer,...

Preston, if Gamblin makes acrylic colors how come I cant find them on their website? As for their oils, their yellows may not fade but they turn very ocherish in about a year. As far as I know, the Mexican outdoor murals by Siquieros have not faded. I think they were done with the polymer paint which were popular in Mexico during his day. Here's one I remember from 1959.

Tim, I'm not suggesting W-N tubes for outdoor murals. You were talking about pigments being classified by the gvmt. Can you give any examples besides the lead? Iron oxides, cadmiums, titanium, cobalt, etc? Maybe I'm misunderstanding you.

Gamblin sells all the traditional oil paints in pints and some of them - blacks, whites, ultramarine and maybe others - in quarts. Considering the huge sizes often seen now in the work of fine artists, I'd imagine some of the manufacturers are selling gallons.
