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.
There are permanent features of the home that have their own colors which cannot be changed when painting the exterior of the home but can have a dramatic satisfaction level that is experienced when the painting is completed. Roofing shingles, paving blocks, concrete surfaces, stones and other such features are prime examples of the colors that should be considered when selecting your exterior color scheme for the home. Homeowners can work off of these colors to make a home that looks uniform and luxurious when the exterior painting is complete.
