I have aluminum siding I want to paint. . Any advice or suggestions. Thoughts on this being a good / bad idea? My house is white with brown trim – yuck. I want to paint a dark olive green with black trim. I was happy to learn … I wish the whole house has aluminum siding because it is the best and easiest surface to paint and very well maintained. Wash the house with a product called "Jomax" done by Zinseer and read the label to apply and blend, buy a gallon for less than $ 20 and will do the whole house, when power washing always spray directly on the surface NO and under the carpet do not want moisture behind the aluminum. Sherwin Williams Super Paint will work and none of 100% acrylic primer and no paint is required, whether you use. I've painted aluminum 20 who still does not look good. And I'd stay away from TSP (trisodium phosphate) phosphates are not good for the environment, plants and also if not rinsed thoroughly burned have poor adhesion and plants, good luck Les the painter, Wow just saw the colors, that's no, no, you do not want to go too dark to really absorb heat which in turn could fasten siding …..
