The rule of thumb has always been to apply a good coat of primer, sand, then apply your color coats. This is still a good rule to follow, but new paint technologies have combined primer and paint into one product, which manufacturers assert will cut down on the number of coats you will have to apply. This newer paint is more expensive, but may be comparable to the purchase of separate primer and paint. Look at reviews of these newer paints, particular from folks that have used it in your area.

If less than half the old paint is left, however, it may be worth stripping it all off. Guertin gets rid of stubborn remnants using shrouded grinders (like the PaintShaver), infrared paint strippers (such as the Speedheater), or chemical strippers (like Multi-Strip), then smooths the wood with a course or two of sanding.

Picking exterior house paint colors is a lot different than picking a color for a shirt or a car. It may help to drive around to observe colors that other homeowners have combined on homes that are of similar size and design as yours. There are also online resources that provide homeowners with the ability to create virtual makeovers of their home by combining colors together through their software programs as well.
