Step-by-Step Guide to Painting Exterior Windows

Here’s how to paint your exterior windows:

1. Preparation is Key

  • Lay down dust sheets: Protect the area beneath the window from paint drips.
  • Prep the area: Clear the workspace. Remove any obstructions, such as plants, pots or furniture around the window.

2. Remove Old Paint and Repair Damage

  • Scrape away loose paint: Use a paint scraper to remove any flaking or peeling paint from the window frame and sill.
  • Repair any damage: Fill any cracks or holes in the wood with an exterior wood filler. Allow it to dry and sand it smooth.

3. Sand Windowsills and Frames

  • Smooth surfaces: Sand the window frames and sills with fine-grit sandpaper to create a smooth base for painting. This helps the new paint adhere properly.

4. Apply Masking Tape and Prime

  • Mask off glass: Carefully apply masking tape to the edges of the window glass, protecting it from paint.
  • Prime: Apply an exterior primer. This provides a base for your topcoat and helps it adhere. Allow the primer to dry thoroughly.

5. Painting Window Frames Exterior

  • Apply first coat: Use an exterior-grade paint, applying it carefully to the window frames. Follow the paint manufacturer's drying time instructions.
  • Apply second coat: Once the first coat has dried apply a second coat for a better finish and durability.

6. Painting Windowsills Exterior

  • Apply first coat: Paint the windowsills using the same exterior-grade paint as the frames.
  • Apply second coat: Ensure the entire sill is coated and allow it to dry fully according to the paint manufacturer's guidelines.

7. Remove Masking Tape and Clean Up

  • Carefully remove tape: Once the paint is dry, carefully peel off the masking tape. Pull the tape off at an angle away from the paint.
  • Clean up: Clear away dust sheets and dispose of them and any paint materials correctly.

By following these steps, you can effectively paint your exterior windows, achieving a professional look and protecting them from the elements.
