The boards around the base of a square wooden column can become damaged or rotten over time due to exposure to the elements. Here’s how to remove and replace them.
Remove Old Base Boards: Use a hammer and pry bar to remove the damaged boards around the column base.
Cut New Column Base Boards: Cut new pieces to match from pressure treated or rot resistant wood, mitering the corners at a 45° angle on a miter saw.
Trial Fit Boards to Column Base: Test fit the pieces around the column to make sure the joints are tight.
Nail Boards to Column: Attach the new base boards to the column using corrosion resistant (galvanized or stainless steel) finishing nails.
Cut and Attach Cove Molding: Miter cove molding to fit around the top of the boards, and attach it with finishing nails.
Caulk Column Base: Caulk the nail holes and corner joints using a quality exterior acrylic latex caulk.
Paint Column Base: Prime and paint the new boards with quality exterior paint.
