“With the correct tools and materials, most DIYers will be able to take this project on,” says Lowe’s store manager Gary McCoy. But he’s also quick to point out a few issues that could complicate the process, including the age of the staircase, the number of steps, and whether they’re carpeted. These roadblocks shouldn’t hinder your plans, though. Even carpet is relatively easy to deal with, as long as you have the right tools and guidance for its removal. However, certain situations require a professional. “Scenarios such as wood damage, stairs not being sturdy enough, mold, and other findings could warrant calling a professional to assist or take on the job,” McCoy says. Because of the wear and tear on handrails and steps, it’s also important to select paint finishes that will stand up to heavy use. McCoy advises DIYers to select a paint that is specifically suited for wood trim and/or can be used to paint over wood stain. A sealer is also necessary for heavy-use areas, which can show wear more quickly if left unprotected. Once you have selected your materials and are ready to start painting, read on for the best way to paint a staircase. Start again at the top of the stairs and apply your chosen paint color to the handrail and trim. Work the brush carefully to cover all the surfaces evenly, and finish each section by brushing with the grain. Apply two to three coats, waiting a sufficient time in between coats to allow each layer to dry.
