For my 8 x 32 foot exterior mural, “Dance of Two Cultures” in Brunswick, Maine I used Golden heavy body acrylics. These paints are wonderful. This mural is now 6 and a half years old on an exterior, West facing wall in Maine. There is a small eve at the roof but nothing that shelters this mural in the least. So this means the paint has been exposed to 6+ years of Maine weather 365 days a year. The wall bakes hot in the summer and endures typical winter temperatures 10 degrees Fahrenheit or below . Blizzards, snow flurries, torrential thunderstorms and hot summer suns, Maine weather can be extreme… and the paint shows no signs of fading.
I used a palette of 9 or 10 colors. Golden has many technical sheets about their products on their site and they rate paints for exterior use. This palette has the highest light fast ratings, and I can now say I agree completely.
The mural was painted, indoors, over the winter of 2007-08. The paints had rich pigmentation making painting easy and a joy. Opaques easily painted over contrasting value and colors.
The color is just as rich today as day one six years ago. Thanks Golden. And nope, I am not getting paid to say this. It’s just great paint.
