Are you thinking about painting your exterior window frames but not sure where to start? Good news—you absolutely can! Not only does a fresh coat of paint boost curb appeal, but it also protects your window frames from the elements. The right paint can prevent damage from moisture, UV rays, and temperature fluctuations, keeping your windows looking great for years.
However, painting window frames improperly can lead to peeling, cracking, or premature wear. The key to achieving a long-lasting finish is proper preparation, selecting the right materials, and following a step-by-step process. This guide will walk you through everything you need to know, from prepping your frames to choosing the best exterior paint for flawless results.
Can You Paint Exterior Window Frames?
✅ Yes, you can! But here’s what you need to know to do it right.
Before you start, make sure to:
- Properly prepare the surface.
- Choose the right paint designed specifically for exterior surfaces.
- Apply paint carefully and in layers for the best results.
Interior paint isn’t suitable for exterior surfaces like exterior doors or windows because it lacks the necessary weatherproofing qualities. Instead, opt for exterior paints and stains, which are built to withstand harsh weather conditions like rain and snow. These paints can keep your window frames in great condition for up to 10 years!
Safety Tip: If you’re working on second-story window frames, always prioritize safety. Use a sturdy ladder, have someone assist you, or hire a professional for the job to ensure a flawless finish.
Follow these steps to paint wood window frames effectively:
Step 1: Prepare the Frames
First, start by cleaning your window frames thoroughly. Use a sponge and a detergent solution to remove dirt, dust, and grime. Rinse the frames with clean water to ensure no detergent is left behind.
For tough, stubborn dirt, you can use a jet washer to clean those hard-to-reach spots. Allow the wood to dry completely before you begin painting to ensure the best adhesion.
Step 2: Sand The Window Frames
Next, it’s time to sand the wood. Wear a protective mask to avoid inhaling dust. The grit of sandpaper you use depends on the condition of your frames:
- For peeling paint or damaged wood, use a coarser grit sandpaper.
- If your window frames are in good condition, 120-grit sandpaper will work perfectly.
Be sure to sand evenly and cover all areas, especially the corners and edges, for a smooth surface.
Step 3: Inspect The Frame
After sanding, carefully inspect the window frame for damage. Look for things like chipped wood, cracks, or small holes. If you find multiple small holes, it could indicate a wood infestation, so make sure to address it.
If there’s any discoloration or soft spots, it might be a sign of wood rot. Treat the rot with a wood hardener and fill in any holes with expanding filler to ensure the wood remains sturdy.
Step 4: Apply Primer
Before painting, check if your chosen paint requires a primer. Apply a coat of primer evenly across the frames, following the manufacturer’s instructions for drying and recoating times.
- If your window frames have never been painted before, apply two coats of primer.
- Allow the primer to dry completely before moving on to the next step.
Step 5: Apply Paint to The Window Frames
Now it’s time to apply the paint! Stir the paint thoroughly to make sure the color pigments are evenly mixed. Using a small synthetic paintbrush, start by painting the edges and then fill in the rest with smooth, long strokes. Always follow the direction of the wood grain for a smooth finish.
Allow the first coat to dry for around four hours. If the wood grain is still visible, apply a second coat. If necessary, add a third coat for complete coverage.
Once the final coat is applied, carefully remove any masking tape and let the paint dry fully. Within one hour, your window frames will be weatherproof and ready to last for years to come!
