A guide on painting UPVC windows, including when to paint them, which paint to use, and how to get the most out of your new window installation.

When to paint UPVC windows

UPVC windows are completely fine to paint, but they should not be painted immediately after being installed in your home. This is because the manufacturing process of UPVC windows includes a step where an extra layer of plastic is added to the windows.

This extra layer of plastic is added solely to make the UPVC appear shiny – and therefore, more desirable to customers. It could also be considered a protective plastic layer because it wears down over time.

It’s best to paint UPVC windows after approximately 12 months have passed from the installation date of the windows. After that year has been and gone, you can expect that extra layer of plastic to have worn itself down through typical wear and tear.

What paint to use on UPVC windows

You can paint your UPVC windows any colour you want, but there are some paints that will be better than others for this type of window. The paint you choose should be one that can properly adhere to plastic surfaces.

In addition, it wouldn’t be a bad idea to take into account the solar bleaching that windows often suffer from. Paint that is protected against UV rays would be ideal.

The best product to look for if you want a tried and tested paint is UPVC paint. This type of paint is readily available in many home improvement and hardware stores, as well as various internet sites like Amazon.

UPVC paint that is manufactured from a reputable company will typically have a guarantee of about 10 years. Of course, you could end up changing the colour scheme of your home mid-way through that, but the idea is that the paint won’t be wearing off your window frames any time soon.
