If you’re interested in changing the colour of your UPVC windows, you’ll have probably heard about spray painting as one option. When professionally done, spray painting achieves a factory finish so your windows appear as though they were originally installed in the new colour. The finish really is that good.
You might have also heard about something called Plasti Dip, or ‘liquid wrap’ or ‘plastic spray’. Plasti Dip and products like it are an air-dry, speciality rubber coating commonly used in the automotive industry. They can be sprayed directly onto plastics and are peelable, flexible and relatively durable. The fact Plasti Dip can be peeled away if the work is botched is the reason why it is so popular with DIYers.
But which is best for changing the colour of UPVC?
Spray painting or Plasti Dip for UPVC? We have been spraying UPVC for a long time and what we know is this: spray paint permanently changes the colour of UPVC, while Plasti Dip temporarily changes the colour of UPVC. The difference in the quality of finish is also apparent between the two: spray paint has a factory-level finish, Plasti Dip is obviously sprayed on.
Spray paint adheres to the UPVC and bonds to it. So, in order to remove it, you have to rub thinning chemicals into it and sand it to the surface. Plasti Dip sticks to the UPVC surface only and can be peeled away easily. This makes it fine for a temporary colour change, but if you want an in-any-way permanent finish, spray paint is best.
In our opinion, for changing the colour of UPVC, Plasti Dip is no good. The product isn’t long-lasting like our spray paint, it is more susceptible to abrasion damage, and pound-for-pound it is more expensive than a professional spraying service. It is also impossible to touch up if it becomes damaged, meaning the whole window will need redoing. This isn’t the case with spray paint which can be sanded down and resprayed well.
Here’s the bottom line: to change the colour of your UPVC and make it appear as though it was originally installed in the new colour, spray paint wins hands-down. It is permanent and if sprayed by our professionals, gives the appearance of a factory finish.
