Can you paint UPVC windows? Yes, but there are some things to know.
UPVC is non-porous and is unaffected by moisture and heat, so it does not expand like metal or swell like timber. It is therefore a good base material for painting. With the right surface preparation (a thorough clean), paint bonds very well to the surface of UPVC windows and will not pull away or flake. However, UPVC must be spray painted. Brush or sponge application doesn’t work because it leaves marks and an uneven finish. It also takes several times longer, making it completely uneconomical.
Another consideration is the paint. Contrary to popular belief, UPVC isn’t plasticised and therefore some plastic paints don’t take well to it. We use a specially formulated, commercial paint that is unavailable at your local DIY store (it’s also a commercial secret). It is crucial the primer and paint used is formulated for spray application. Every over-the-counter product we’ve seen can only be applied by brush, which as already noted is not a good way to paint UPVC windows. Unfortunately, we do not know of any UPVC primers and paints available at DIY stores that are sprayable.
This renders the job of painting UPVC one for a specialist, and we haven’t carefully engineered our advice to lead this way. The fact there are no known high quality sprayable UPVC primers and paints at DIY stores makes it so. Can you paint UPVC windows yourself? If you’re happy with brush marks yes. Otherwise no.
