1. PREPRIMED BEADBOARD
Beadboard comes in different-width tongue-and-groove strips that fit together to look like one continuous bead-and-board panel. It also comes in lengths anywhere from 8 to 16 feet. Pick the length that’s just longer than your porch is deep so one board can run the whole depth of the ceiling without seams.2. LATTICE
For covering the 1/4-inch expansion gap around the perimeter of the beadboard. Lattice is flat 11/2-by-1/2-inch stock, usually made from treated pine. For the amount you'll needmeasure the perimeter of the ceiling, then add 10 percent.3. 2-INCH FINISH NAILS
For nailing up the beadboard. Make sure you get nails made to fit the gun you rent. About 200 will suffice for 100 square feet of 1x6 beadboard, which means two strips is more than enough. 4. 1-INCH BRADS
For attaching the lattice. One strip of brads should be enough.
