The frequency of your exterior repainting depends on several factors, including where you live, what your house is made out of, and what it was painted with. In North Texas, we’re protected from the salt sprays our coastal friends down south must consider. Even still, strong sunshine and excessive heat during the summer can take a serious toll on the life of your paint. Dark, oil-based paints may fade especially quickly. The paint may blister, too, or form bubbles on the surface. So there’s no concrete answer for how often to repaint your home — but if you start to see chips, cracks, bleaching, blistering, or any other issue that takes away from the appearance of your home, it’s time to consider repainting.
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.
Small random-orbit or pad sanders make this job go faster. (Wallis first covers these boundaries with Synkoloid patching compound so no edge is visible after sanding.) As shown, you want to make sure that there is a feathered, smooth transition from exposed wood to old paint. For areas that might get close scrutiny, you can follow up with a 100- or 120-grit rubdown to erase any scratches.
