How to Paint a Window Frame

Window frames provide a decorative and protective box around window panes. The frames are usually wooden, and painting around them and on them requires a great amount of attention to detail. The goal of any paint job on window frames is to prevent messy mistakes and the need to scrape paint off glass. Paint a window frame with care and patience, and it can look professional and neat without a lot of effort or clean up.


  1. 1
    Clean the window. Use a glass cleaner and some paper towels to clean the inside of the window before beginning to paint the frame. This will keep any dust and dirt that may be gathered on the window from getting into the paint.
  2. 2
    Tape the hardware. Use painter's tape to cover any hardware or areas that are not meant to be painted, such as hinges, locks and catches. If removing these items is easier than covering them with tape, take them off the window and set them aside.
  3. 3
    Tape the window. Prevent paint from getting onto the glass by taping off the window with painter's tape.
  4. 4
    Paint any muntins. Muntins are horizontal pieces of wood going across the window. Paint them slowly with a small paintbrush, making even strokes across the wood from 1 end of the window to the other.
  5. 5
    Paint the horizontal pieces. Using the same strokes and brush as on the muntins, paint the top and bottom horizontal pieces of the window pane.
  6. 6
    Paint the vertical cross pieces.
  7. 7
    Paint any additional top, bottom or side pieces of wood that are on the window pane.
  8. 8
    Paint the window molding.
  9. 9
    Remove the painter's tape from the glass and hardware. Do this while the paint is in the process of drying. If the tape is not removed until after it the paint is completely dry, it can chip paint off the window frame.
  10. 10
    Allow the paint to dry on the window frame. This may take up to 24 hours to dry completely.
  11. 11
    Scrape off any paint that landed on the glass. Use a paint scraper to gently rub away at any paint marks that are on the window. If the paint scraper is too large to manage or reach the corners, try using a small razor blade.
  12. 12
    Once the paint is dry, replace any hardware that was removed before the window painting process.


  • Paint double hung windows by starting on the lower outside sash, then paint the upper sash on the inside.
  • Use a tapered sash brush for best results and attention to detail on the window pane.
  • Paint casement windows while they are open. Be prepared to leave them open while the paint dries, up to 24 hours.


  • Do not paint the window jamb. This will cause the window to stick when trying to open it.
