Ready to makeover that dated wood paneling? Home repair expert Henry Harrison teaches a homeowner how to paint paneling, starting with the most important step, which is surface preparation. A deglosser is wiped onto the paneling, acting as a liquid sandpaper so the paint will stick. Next a primer is applied with a paintbrush and roller. If any grease or stains bleed through the primer, several coats will be needed. Apply caulk to fill in any visible seams. Then apply your first coat of paint, moving the roller both vertically and horizontally to fill in all areas. Wait at least 8 hours, then apply a second coat for a perfect finish.
