How to Fix Peeling Paint on Door Frames

Replace the door frame if your home was built before 1978 because the paint may be lead-based. Approximately 75 percent of homes built before 1978 have some type of lead-based paint in them. If this is the case, it is better to replace the frame rather than sanding and repainting it.

Inspect the wood for any signs of deterioration. Replace any part of the frame that is deteriorating. When replacing a frame, prime the entire piece of wood with a waterproof primer before hanging, including the ends. This will prevent wicking, where moisture travels through the wood and gets under the paint. While it is possible to pry door frames up and paint the backside, this is usually unnecessary unless you think that wicking is a problem.

Scrape, sand or use a chemical striper to remove as much of the paint as you can on the door frame. Follow the manufacturer's directions when using chemical strippers. Use 100- or 150-grit sandpaper to remove the paint and then switch to 220-grit to smooth the wood.

Wash the surface with a damp cloth to remove any dust and allow it to dry before moving to the next step.

Prop open the door or remove it from its hinges before you begin painting.

Coat the hinges on the door frame with rubber cement. The cement will protect them from paint and can be rubbed off when you are finished.

Purchase a high-quality waterproof primer, even if the wood frame is indoors. Indoor doors and window frames have to deal with a lot of moisture and need to be protected. The choice between oil-based and latex is up to you. Remember that while you can use latex paint over an oil-based primer, you cannot use oil-based paint over a latex primer. Select either an exterior or interior paint designed for high moisture conditions. Glossy or semi-glossy paints are usually used for woodwork.

Using a 2-inch angled brush, start at the top of the frame and work your way down.

Allow the paint to dry. The can of primer should list a recoat time, which is the amount of time necessary for the paint to dry before it can be painted over. Then, apply two coats of paint using the same procedure listed in Step 8.
