Quick Custom Wainscoting Add intricate architectural detailing with ease. This elegant wainscoting looks like the result of hours of elaborate work, but it just calls for a visit to a home center. The ready-made PVC latticework panels are mounted on the wall above the baseboard and topped with a chair rail made from 1x4 and 1x2 boards. Screen molding is nailed in place to hide the joints where the panels meet. Paint the raw wood pieces with white paint color-matched to the PVC.
