You can change brown UPVC windows to white by having them spray painted. Solvent-Based spray paint will bond with the plastic to create a change in colour which will last for around 10 years. This assumes proper surface preparation steps being taken and the paint itself being applied by a professional with a gun.
Now, you may be tempted to try it out yourself with a canister of spray paint, but unfortunately, the only way to convincingly change the colour of brown UPVC to white is to spray paint it with a gun. Aerosol cans are not powerful enough to jettison the paint evenly over a large surface area. If the desired effect of the painting is to make it appear as though the windows were originally manufactured in white, use a gun.
Advice from our experts
Electric spray-painting guns are relatively inexpensive and can come in handy for other home improvement projects. Paint wise, you want a solvent-based paint because these act as the primer on the first coat, so no dedicated primer is needed.
Brown windows need at least three even coats of paint to cover the brown up, and some doors need up to four coats of paint for a perfect colour change.
Spray paint can be temperamental and the fact you are spraying outdoors means you have to choose the day you paint wisely. You want to paint in the shade, at a temperature above 12°C but below 30°C. You can’t paint in the rain or in direct sunlight. Paint on a dry day and leave enough time for 30-minutes between coats.
