White uPVC window frames can be painted, but there are a few things you need to know before you go ahead with such a project.
The first thing you need to know is white uPVC window frames need spray painting to achieve a factory finish. You cannot use a brush. Paint brushes leave brush lines which are ugly and impossible to correct.
You need to use a spray painting gun for rapid coverage of an area. You cannot use a cannister of spray paint for UPVC frames because a) it’ll take forever, and b) the coverage won’t be thick or consistent enough for a great finish.
The paint itself
There’s only one type of paint that creates a durable finish on UPVC: solvent-based paints developed for plastics which bond with the plastic on a molecular level. Kolorbond is a good example of such a paint you can buy.
You cannot use paints that bond through adhesion (for example, acrylic paints) because they do not meaningfully bond with the substrate – they merely ‘stick’ to it, and what sticks to UPVC will become unstuck over time.
The time involved
Painting white UPVC frames is a time-consuming endeavour. You will spend at least 2 hours cleaning the UPVC and masking the frames. Only after you have done this can you begin the painting process, which takes another 4-5 hours.
It takes a professional company like us a day to paint the window frames on an average house. Some projects need to be spread over two days depending on the weather and the number of window frames that need painting.
With us, you should budget circa £150 per white UPVC window frame.
