A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective. Westminster House Painting CO
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.
