How to properly prep and paint interior window frames
Your windows do more than let in the beautiful Central Indiana sunlight—they frame your view of the world. Over time, however, interior window frames can take quite a beating. Here in Indiana, our dramatic climate swings—from humid, sticky summers to freezing winter temperatures—cause wood frames to constantly expand and contract. This temperature fluctuation can lead to condensation buildup, cracked paint, and peeling.
Whether you live right here in Mooresville or over in Greenwood, Indiana, giving your window frames a fresh coat of paint is a fantastic way to elevate your home’s interior. Here are four professional tips to ensure a beautiful, long-lasting finish that stands up to the elements.
1. Clean Thoroughly and Tackle Moisture
Before grabbing a brush, you must clean the frames. Because of our humid summers, window tracks and frames often accumulate dust, pollen, and even mildew from condensation. Scrub the wood with a mild cleaning solution, rinse with clean water, and let it dry completely. Next, use a putty knife to scrape away any loose, flaking paint.
2. Sand and Patch for a Seamless Base
Once dry, sand the frames with medium-grit sandpaper to scuff the surface, which helps the new paint adhere. Fill any gaps, cracks, or nail holes with a premium paintable wood filler or acrylic caulk. Since winter freezes can cause drafty windows, sealing these small gaps now helps protect both your energy bills and your new paint job.
3. Tape the Glass with Precision
Save yourself hours of scraping dried paint off glass by using high-quality painter’s tape. Apply the tape right up to the edge of the wood, leaving a microscopic gap (about 1/16th of an inch) on the glass. This allows the paint to seal the joint between the wood and the pane, preventing condensation from seeping behind the frame.
4. Prime and Use Durable Semi-Gloss Paint
Always apply a moisture-resistant primer first, especially on bare wood. For the topcoat, choose a premium semi-gloss or gloss acrylic latex paint. These finishes are highly durable, easy to wipe clean, and flexible enough to withstand Indiana’s seasonal temperature swings without cracking.
