Painting Wood Siding and Trim
Whether it’s lap siding, board and battens, or porch railings, if you want a successful paint job, it all starts with preparation. As is often the case with wood surfaces that have to deal with Mother Nature, the old paint begins to flake, exposing raw wood. Before you pick up your paintbrush, you need to remove as much of the old, flaking paint as possible with a paint scraper.
If you have a large area in need of scraping, you’re best bet is to use a drill motor or cordless drill with an attachment specifically designed for stripping paint. A synthetic fiber wheel does a great job and lasts much longer than the old sandpaper wheels that are often used.
For very stubborn spots, you could also apply a chemical paint stripper. This, however, will mean that the job is going to take you longer to complete because the surface needs to be completely dry before moving on to the next step. Once the loose paint is removed, prime the raw wood with a good quality primer before applying a finished coat of paint.
