Many consider exposed beams to be an eyesore that conflicts with other finished surfaces in a home. Help these surfaces blend in better by finishing them with paint. Unfortunately, not all beams are suited for paint adhesion. Learn the proper ways to prepare the beams based on their composition, or peeling will result. Take the time to protect areas adjacent to the beams, or you may stain them with paint overlap. Use a particular brush to apply the paint, or the finish may dry with subtle brushstrokes.
