Apply wood filler to all visible nail holes and any small imperfections in the wood. Immediately wipe off any excess wood filler using your finger or a damp cloth to avoid extensive sanding later. Then, use paintable caulk and a caulk gun to fill all the seams where the wood pieces meet the wall and where two wood pieces meet each other (e.g., in corners or where the horizontal trim meets the vertical battens). Smooth the caulk with a wet baby wipe for a clean, seamless finish. This step helps create a smooth, paint-ready surface and makes the installation look professional and fully integrated.
