A splash of fresh paint on a house with weathered siding can be transformative. Whether the house is new or old, a paint job makes heads turn. At the same time, a good quality exterior latex paint also provides a protective coating on the surface. But before applying paint, follow the lead of painting pros and take the time to prepare the surface for the best looking and longest lasting results.

To prepare prime and paint 1,500 square feet of wood siding on a house, a painting contractor will charge $1,673, which includes labor and material. This is not a trivial job, but you can do it yourself paying $700 for the material and enjoy saving 58%. If the siding is damaged or requires removing layers of paint and repair work, the time and cost will be considerably more.

The painting process includes several phases. If the siding has areas that are dirty or covered with mildew, wash them using a garden hose with a scrub brush attachment or rent a power washer. Scrape any loose or flaky paint and sand them; also sand any bare spots so they're smooth. Then apply the first coat of primer, followed by a topcoat of paint to all the surfaces allowing it to dry between applications. Protect the surrounding plants and shrubbery with drop cloths while doing the prep work and painting.

If your house was built before 1978, it is possible that lead paint was applied to your siding. If lead is present, dry scraping and sanding the old paint is highly toxic to you and your neighbors, especially to small children. It is a job that should only be done by professionals trained in lead-safety practices.
