Deciding which paint to use has gotten much easier now that acrylic latexes have pushed oil-based paints almost to extinction. The acrylics offer superior performance (they don't harden with age, the way oils do, so they move and breathe without blistering), they don't mildew as readily, and they emit fewer VOCs, so they comply with new air-quality regulations. They also work over both oil- and water-based primers.
Better quality paint means you will paint fewer times over the years, and you'll get better coverage when you do paint. Paint technology has improved dramatically in the past few years, with colors guaranteed to last longer than ever before. You may be tempted to skimp on paint to save money up front with a cheaper brand, but you're bound to have trouble and eventually pay more in the long run. House Painting Arvada
