How to Paint uPVC Windows

uPVC (otherwise known as Un-plasticised Poly Vinyl Chloride) is most likely the most commonly used material for windowsills and window frames. However, they can be a little bit boring or even ‘ugly’ looking, so today we are going to show you how to paint uPVC windows to keep them looking fresh and interesting!

With long lifespans of 25-30 years, uPVC can withstand the harsh British weather. So understandably, it is a popular choice. However, 25-30 years is a long time to have the same windows, so why not mix it up?

Can you paint uPVC?

With the right product, yes, you absolutely can paint uPVC. In fact, there are a couple of ways in which you can do this.

  • Paint directly onto uPVC
  • Prime the surface and then paint

Which option you decide on depends on the type of paint and finish you would like. We will go through the differences and explain why you might choose one over the other below.

Paint directly onto uPVC

It is very possible to paint directly onto uPVC, so long as you use the correct product. One such product is Owatrol Deco, our oil-based multi-surface paint suitable for use on all surfaces. It is available in 10 decorative RAL colours and does not require any priming or undercoating before use.

Its high gloss finish is extremely flexible, meaning it will not peel or flake, making it the perfect solution for flexible surfaces like uPVC and other plastics.

Application of Owatrol Deco

  • Surfaces must be clean, dry and free from oil, grease and other surface contaminants.
  • Apply 2 coats of Owatrol Deco over the entire area allowing drying time between coats.

If you do not want a high-gloss finish and instead would like a satin finish, then your other option is to prime the surface and then cover it with an exterior paint of your choosing.

Prime the surface and then paint

You could do the long and arduous task of sanding the surface, cleaning it and waiting for it to dry, then applying a primer, waiting for that to dry and then finally applying your chosen paint – but that’s a whole lot of unnecessary work and time wasted!

Instead, we recommend using Owatrol E.S.P (Easy Surface Prep) – our shiny and smooth surface primer that completely removes the need for difficult and time-consuming sanding and leaves the surface ready for paint to bond to.

What makes it even better, is that if the weather decides to change, (we are in Britain after all!) E.S.P can be painted over anytime after 2 hours and up to 7 days later!

Application of E.S.P

  • First clean and dry all surfaces to remove oil, grease and other contaminants and remove any loose and flaking old finish.
  • Apply ESP generously with a clean, dry, lint-free cloth.
  • Leave to stand for 5 minutes then lightly wipe over the surface in one direction with a clean cloth to remove any excess ESP.

Once the surface has been primed with E.S.P and then dried, you can then apply your chosen exterior paint finish.
