Begin your painting project by pouring thoroughly mixed paint into a bucket and dipping a quality 2"-2½" wide nylon/polyester brush into the paint.
With your brush, paint (cut in) along the perimeter of the paneling. Start at a top corner and continue along the ceiling and around the baseboards.
Starting at the top of your project area, paint into the grooves of the panel. Follow the direction of the panel.
Pour paint into a paint tray and work the roller into the tray until it is fully loaded with paint. For best results, use a ½"-¾" roller cover.
Starting in a 3' section at a top corner of your project area, roll the paint onto the paneling, working from the top to the bottom.
Be sure to roll over the cut in area as well. Forming a column from ceiling to floor, paint the next 3' section directly beside the previous one.
Repeat the process of forming columns and blending sections until the project is complete. The colour of the panels will change, however the grooved shape of the panels will remain.
