Our Guide to Painting uPVC Windows

Are you thinking about painting your uPVC windows? You aren’t alone. Many homeowners want to revamp their exterior without the expense of installing new windows.

You may be wondering if it is ok to paint uPVC windows. The answer is that it is possible to paint them, but you should consider a few things before going ahead.

Read our handy guide to discover everything you should know about painting uPVC windows.

1. Why paint your windows?

You probably chose uPVC windows because they are durable, easy to clean, low maintenance and weatherproof. Also, they look good!

There is no need to do anything but wipe your frames with a soapy cloth to keep them looking clean and shiny. However, if you have had your frames for a while, you may want to change the colour and appearance of the windows to suit your style and create some kerb appeal.

2. Painting new Windows

If your windows are less than 12 months old, we would recommend that you do not paint them. When uPVC windows are manufactured, an additional layer of plastic is added to create a shine. The resin left on the frames means the paint will not adhere correctly.

If you are keen to change the colour of your frames for a new look, you will simply have to be patient.

3. What paint should I use to paint my uPVC Windows?

You can choose any colour you like, but you must select the right kind of paint.

The ideal paint will adhere well to the plastic surface of the frames. Since it will also be exposed to the elements, choosing a paint that resists UV exposure and discolouration is essential.

Rawlins supply specialised uPVC paints that have excellent adhesion and weatherproof qualities.

4. Should I spray paint uPVC windows?

Spray painting is the best way to apply paint to uPVC windows; most professionals use this method.

Spraying will give you a smooth finish without streaks and marks that a paintbrush can leave.

For the best results, follow these spraypaint steps:

  • Use protective coverings on the glass and house exterior to ensure you only apply paint to the frames.
  • Remove debris and clean the window panes and frames to ensure the paint has a clean surface to stick to. Don’t forget the trim and sills too.
  • Next, you must make the surface abrasive to help the paint cure effectively. Use sandpaper to roughen the surface of the frames.
  • It is crucial to apply a primer before you paint. It will ensure a better and smoother finish, especially if you paint a lighter colour over a darker one.
  • Now you have prepped your windows, it is time to start painting. You will need a minimum of three coats to get a professional finish, and you may need more.
  • Only remove your protective coverings once the paint has dried for at least thirty minutes.

5. Can I paint uPVC doors, too?

The good news is that you can use precisely the same method to paint a uPVC door, creating a whole new style. You can also paint the inside of your uPVC frames.

What are the disadvantages of painting uPVC windows?

We think that painting uPVC windows reduces some of their unique properties. They are designed to withstand all weather and are very robust. Once you begin sanding the outer surface of the frames, you will be compromising their effectiveness.

  • Painting uPVC windows has many disadvantages:
  • Time consuming and challenging
  • Possibility of fading, cracks and chips
  • Damage to the uPVC
