Can you spray uPVC Windows?

The answer is yes, but the real question is would you really want to? The uPVC window can be painted using a special type of paint called the uPVC paint, but spray painting your window will cause you to lose the good surface finish that your window already has. Despite all that uPVC windows are meant to be sparkling white & have no maintenance at all, So if you are looking to make it look colourful I would suggest getting it laminated.
