How to Build Cedar-Slat Privacy Screens

On a flat surface, position a pair of posts with their outside edges 35-1/2 inches apart and the ends flush. Apply waterproof glue to the posts and arrange the slats on the posts, starting at the top (Project Diagrams). Align the top edge of the top slat with the tops of the posts and each remaining slat with the lines on the posts. As you place each slat, tack it to the posts with two 1-1/2-inch brads or 4d galvanized finish nails. Use a carpenter’s square to check that the slats are 90 degrees to the posts, and let the glue dry. Repeat for additional post and slats.

Carefully turn over the screen. Drill pilot holes through the posts, centered on each slat, and drive 2-inch deck screws through the posts and into the slats. Repeat for each screen.

Apply an exterior wood preservative in the color you want -- we used a semi-transparent deck stain (Cedar Naturaltone).
