Sand the Exterior Walls
Sanding the exterior walls is necessary to provide a real mechanical bond between the coats of paint. If you don't rough up the surfaces sufficiently, your paint job may look good when you walk away from it, but in just a few years, the paint starts to show all sorts of errors. Especially if you're working with oil-based paint, you may be tempted to just start painting, since oil paint wets the previous coat so well that it sticks well initially and looks great. However, for a finish that will ensure happy, repeat customers, do the sanding work to create a paint job that lasts. Refresh the surfaces of weathered wood with medium-grit paper. For areas where you're going to use glossy or semigloss paint, such as door and window trim, opt for another pass of sanding with fine-grit paper. Sanding is a crucial step for any paint job, so be sure to pass over all the existing paint thoroughly to create a rough surface that's ready to receive the new paint. 5
Prime the Walls
Priming also helps new paint stick to previously painted surfaces. You need to prime any areas where old paint has already been peeled off, but to create a cohesive paint job that looks good all over, prime the entire house.
