How to Refinish a Window Frame

Wood window frames are highly prized in many homes, but they require regular maintenance to stay in good repair. However, by completing this maintenance as needed once a year, you can prevent the window frames from rotting, as well as other possible problems. Plan on checking your windows in the spring, while the weather is warm. That way, you can make necessary repairs without losing necessary heat or cold air when the window must be removed.

Step 1: Look for any windows with frames that are peeling, faded, or have rotted areas. If the majority of the frames are in bad shape, plan on refinishing all of the window frames to prevent uneven wearing. However, if there are only a few window frames affected, you can refinish only those frames.

Step 2: Strip the surface of the window frames using a chemical stripper in gel form. Apply the gel using a paintbrush, then wait 10 minutes, or until the finish starts to bubble. Then remove the finish with a plastic scraper. Continue until all of the finish is completely removed.

Step 3: Remove any rotted sections of wood with a chisel and hammer. Fill the areas you had to remove with latex wood filling compound, using a putty knife to apply and smooth any patches. Sand the patch after the compound is fully dry.

Step 4: Give a light, overall sanding to the window frame, making sure that the wood is as clean and smooth as possible. Wipe down the window frame with a tack cloth to remove dust.

Step 5: Prime the entire window frame with an exterior wood primer. You may want to use painter's tape to protect the glass from the primer: but you can also clean up any problems with a razor once the primer has dried onto the glass in the window frame. Use painter's tape to cover other areas that should not be painted as well.

TIP: If your window frames are simply stained, skip this step. Keep in mind, however, that paint will easily cover patched areas that may become highlighted when stained.

Step 6: Paint the window frame, paying particular attention to the corners and other areas that may be easy to miss. Let the window frame dry completely.
