The method for repairing the baseboards in your home will depend on what is wrong with them. In some cases, replacement is the most effective approach. It is not difficult to swap out baseboards when they become dented, chipped or warped. If the problem is gapping, you will find caulking an effective and straightforward way to fill a hole or close the space between the wall and trim.

Caulking allows you to fill gaps in the baseboard.

Step 1

Apply one coat of primer to the baseboard. Follow the instructions on the primer for application. Allow the primer adequate time to thoroughly dry.

Step 2

Insert colored caulk into a gun. Select caulk with a color close to the wall color.

Step 3

Hold the caulk gun at a 30-degree angle over the gap. Squeeze the handle on the gun slowly, so you can control the flow of the caulk. Slide the gun along the space in the baseboard. Fill the gap enough so the caulk extends over the edge slightly. For example, if filling the space between the wall and baseboard, use enough caulking so it sits just a little over the edge.

Step 4

Run your finger over the caulk to smooth it. This will push the caulk down to ensure the gap seals.

Step 5

Wipe the edging of the caulked area with a wet, tile-grout sponge. This blends the caulk to the surface of the wall or baseboard and removes excess. Rinse the sponge often and repeat the feathering process until the caulk is smooth. Allow the caulk to cure once blending is complete.

Step 6

Paint the baseboard after the caulk hardens. This will probably be the next day at the earliest. Follow the recommendation on the caulk tube for proper drying time.
