Giving new life to old UPVC windows is becoming a popular choice for homeowners who want to update the look of their property with different window frames. However, this might be more difficult than you think.

Instead of giving up from the very beginning and replacing windows, follow these steps to obtain a high-quality finish.


How to paint UPVC windows: the main steps

  1. Mask the surfaces that need to stay clean: this is an important phase, or else you will have to clean all the window panes and the walls. Don’t take it for granted, take your time to make it properly!
  2. Clean the window frames with a damp cloth and dry the surfaces.
  3. Apply a layer of primer: this will help the paint settle onto the UPVC surface much more easily.
  4. Spray paint your windows (the easiest and quickest technique): once the surface has been fully prepared, painting can begin. We suggest using spray paint to avoid unaesthetic brush marks. It is recommended to apply 2 or 3 layers of paint, but depending on your chosen colour, it could take a few more to ensure your windows are completely covered.
  5. Allow the paint to dry and remove protective coverings: when you are sure your windows are dry, remove masking tape and paper (or film) to reveal your newly painted windows. Ta-daaa, enjoy the perfect finish you achieved!
