Window frames take a beating on the outside and are often neglected on the inside. Repainting and performing minimal maintenance every three to five years will ensure that your windows are better protected. Well-maintained windows complement and complete a house. The initial repainting may be a lot of work, especially if the paint job hasn't been touched for years, but subsequent jobs should be easier. Difficulty of the project depends entirely on the state of the paint that is currently on your window.

  1. 1

    Assess the state of current paint job. If current paintwork is in relatively good condition and you simply want to change the colour, you do not have to remove any paint. If paint is flaking, remove chips with a scraper and sand rough patches to even the surface. You may also use a chemical paint remover to strip paint down to bare wood.

  2. 2

    Repair the window. If there are any cracks or nail holes, fill them with putty or wood filler. Sand over fills to smooth the surface.

  3. 3

    Sand frame. Sand down the entire frame with a coarse sand paper. This will create a ridged surface for the adhering new paint. Wipe frame with a clean cloth to get rid of excess dust and debris.

  4. 4

    Prime the window frame. If you have stripped the frame down to bare wood, you need to apply a primer coat. After primer has dried, wipe it down with a cloth to remove any dust.

  5. 5

    Apply an undercoat layer. The undercoat is only needed if you have just primed the window frame or if the new colour of the windows will be lighter than the old. If current paint is significantly darker than your new paint, you may have to repeat this step again. When dry, wipe surface clean.

  6. 6

    Apply top coat. Use the same brand as the undercoat. This is your finishing coat, so be careful to avoid dripping.

Tips and warnings

  • Be careful of lead paint in houses built before 1960. Test for lead and use a chemical paint remover to remove paint if the test is positive or if you are uncertain.
