How to: paint PVC windows


Do you have plastic windows and think they no longer match your home? Or were they once brilliant white and now they are not?

Good news: you don't have to replace those ugly PVC windows right away. Time for a dash of paint! Give them a colourful makeover so they look as good as new again.

"Can PVC windows be painted? And how do you do that? What paints adhere to PVC?" In this roadmap, you will find step-by-step instructions on how best to go about it. You will also find the right products for the job. Easy, right?

By the way, aluminium windows are also perfect candidates for a lick of paint. Find out how to paint aluminium windows here. Or do you have wooden windows? Then we can help you too! Find out how to paint wooden windows or how to stain wooden windows.


Painting PVC windows inside

Step 1: preparation


  • Put painters tape along the window frames and cover the surrounding area

  • Clean and degrease the windows completely 

  • Roughen up and dust off the plastic

First, it is important to properly clean and degrease the windows. You can do this with water and detergent. Be sure to rinse thoroughly to remove any residual detergent.

The next job is one that not everyone likes to do, but keep this in mind: cleaning up afterwards is not something anyone likes to do either 😉 By covering the windows and the surrounding area, with masking tape and covering material, you make sure you don't make a mess.

Then take some sandpaper - not too rough, e.g. grain 220 - and go over the plastic with it. The aim is to make tiny, almost invisible scratches. This will allow the paint for PVC to adhere better.

When you have sanded, there will of course be some dust on your windows. Use a soft brush to get rid of that. If it were to end up in the paint, you won't get an even result.

Step 2: applying adhesion primer


  • Put a multi-primer on the windows, one coat is sufficient 

  • Wait for the multi-primer to dry before continuing

Multi-primer? Adhesion primer? 🤔 These are two names we give to primers that are specially designed to adhere well to non-standard substrates, such as PVC, that is. Its counterpart is a classic wood primer. 

If your windows have been painted before and the paint still looks absolutely picture-perfect, you don't need to apply adhesion primer. So you can go straight to step 3! 

Now it's time to put the multi-primer on your window frame. Use a round paintbrush for the edges and a felt paint roller for the flat areas. Ideal for next to and between the glass. One coat of this powerful primer is enough.

And then it's time to wait... Only when the primer has had enough time to dry can you continue painting. You can find exactly how long this takes on the tin or in the technical data sheet.

Step 3: lacquering


  • Paint the windows in one to two coats

  • Remove the tape and foil again

So, with the windows nicely primed, you can now start painting! For indoor windows, you can use a water-based paint. Very often a satin finish is chosen, but matt or high-gloss is of course also possible.

Matt lacquers are aesthetically slightly more popular as they blend neatly with the walls, for example. High-gloss lacquers, on the other hand, are the strongest. The more gloss, the stronger the lacquer. Satin gloss, therefore, somewhat combines the best of both.

Paint the window again with a round brush along the edges. Again, use a paint roller to roll out the paint along the lengths of the window frame. Give the paint enough time to dry before applying another coat.

A new coat... So does that mean you need more than one coat? Yes and no. With just one finishing coat, you will have a nicely finished window in itself. However, your paintwork will last a lot longer if you apply a second layer. This is because the extra layer provides extra scratch resistance, among other things. We definitely think that's worth it!

There, you are almost there! Just remove the tape and you can admire your beautifully painted window. You can be really proud of that, can't you? 🤩

Painting your PVC windows outdoors

Are you going to paint your PVC windows along the outside as well? Then you can perfectly follow the steps above. It doesn't work very differently, but there are still some things to consider:

  • To tape rough surfaces around your windows, it is best to use a special tape. Green tape is suitable for brick, crepi, concrete or rough wood, for example.

  • Outside, you don't have the option of stopping after one coat of finish. Exterior windows are much more susceptible to wear and tear. Due to rain, wind, sun, etc. So you definitely need sufficient layer thickness to prevent rapid wear and tear. That is, at least two coats.

  • For your PVC windows outside, you can use water-based paint just like indoors. If it is suitable for outdoors and with the right multi-primer underneath. Synthetic primer and lacquer used to be the go-to choice for exterior windows. Still applicable, but the idea that water-based lacquers cannot be used outside is outdated. For darker colours, they're even a better choice. They retain the colour better.
