secure spindles in from bottom of rail
use polyester wood filler to patch holes
Reassemble the Balustrade
Nail or screw the spindles in from the bottom of the rail (Image 1), then repeat on the top rail with the same spacing. Reuse the top hand rail and connect the balustrade to the columns using 2 1/2 inch galvanized finish nails, or stainless steel screws. Use the two-part polyester wood filler as needed to patch any holes (Image 2). Using an orbital sander, sand the wood filler after it has dried. Complete by priming the wood and caulking the nail holes. Finish with a final coat of paint.
