Corner Boards Corner Boards
Corner boards are one of the methods used to trim the corners of siding on a home. Once finished, the corner boards look like vertical pieces of trim on horizontal siding. Many old types of boards are made out of low grade wood that warps and cracks, which means it needs to be replaced.
- Step 1: Check for which corner boards need to be replaced and which ones just need to be touched up.
- Step 2: Use a flat bar to carefully rip out the boards that need to be replaced. Make sure you don't pull up the siding or leave in any nails.
- Step 3: Paint the new corner boards with exterior primer and let dry.
- Step 4: Nail in the new boards with long, rust resistant nails. You may want to drill in holes for the nails if you have invested in higher quality wood.
- Step 5: Paint the boards with an exterior paint that matches the other trim.
Touching Up Old Corner Boards
Some corner boards won't need to be replaced entirely, but have cracks that need to be filled and painted. Make sure to sand each of them down before priming and painting the trim.
