Building a privacy or board-on-board fence? Need to repair a privacy fence? This 10-pack of wide privacy-fence pickets will help you get the job done. These long-lasting fence boards are pressure treated for above-ground use. They can be stained or painted. The treated pickets need to dry thoroughly before painting or staining. To test, drop some water on the wood. If the drops soak in, the wood is ready to paint.
