Your window frames play a key role in your home’s overall curb appeal. Over time, exposure to sun, wind, and moisture can cause paint to fade, peel, or crack. Repainting your exterior window frames is a simple yet impactful way to refresh your home’s exterior and protect it from the elements.
Here’s a step-by-step guide on how to paint your window frames properly—plus what kind of paint to use and when it’s best to bring in the pros.
What type of paint to use on exterior frames?
For best results, use high-quality exterior paint that’s formulated to withstand harsh weather and adhere to the type of material you’re painting. Here’s what to look for:
- 100% acrylic latex paint – ideal for wood, vinyl, and previously painted metal
- Oil-based enamel – good for bare metal frames or high-traffic areas
- Satin or semi-gloss finish – durable, easy to clean, and highlights trim detail
- Exterior primer – always prime bare or patched areas for proper adhesion
Be sure the paint is UV-resistant, mildew-resistant, and flexible enough to expand and contract with temperature changes.
How to properly paint exterior window frames
Follow these six essential steps for a smooth, long-lasting finish:
Step 1: Clean the surface
Use a mild detergent and warm water to clean the window frames. Remove dirt, cobwebs, and mildew. Rinse and allow to dry completely.
Step 2: Sand and scrape
Lightly sand the frame to scuff glossy surfaces and improve paint adhesion. If old paint is flaking or peeling, use a paint scraper to remove it. Wipe down with a tack cloth to remove dust.
Step 3: Mask off glass and siding
Apply painter’s tape around the windowpane and siding to protect nearby surfaces. Use plastic sheeting if needed to avoid splatter.
Step 4: Apply primer (If Needed)
If the surface is bare wood, metal, or patched, apply a coat of exterior primer. This ensures better paint coverage and prevents future peeling or fading.
Step 5: Apply the paint
Use a high-quality brush for control around edges. Apply paint in thin, even coats, working with the grain (if wood). Avoid overloading the brush to prevent drips.
Step 6: Let dry and apply a second coat
Allow the first coat to dry fully before applying the second. Two coats offer better coverage and protection, especially in exposed areas.
