Painting UPVC Windows: A Step-by-Step Guide With Videos
Painting UPVC windows is a viable option for updating the look of your home without the need for a complete window replacement. Unlike traditional wooden frames, UPVC windows require special preparation and materials to ensure the paint adheres properly and lasts over time. The process involves thorough cleaning of the frames, selecting an appropriate paint that can flex with the material, and applying it meticulously to avoid drips and uneven coverage. This not only enhances the aesthetic appeal of your home but also provides an opportunity to personalise the exterior according to your taste.

Customising the colour of your windows can set your property apart and add to its curb appeal.
Preparation and Cleaning
Before painting your uPVC windows, a meticulous preparation phase is essential for a lasting and professional finish. Two critical steps are necessary: thorough cleaning of the surfaces and keying the surface for better paint adhesion.
Surface Cleaning
First and foremost, cleaning the uPVC window frames is vital to ensure that any paint applied adheres well and lasts longer. Begin with:
- Remove Dirt and Grime: Create a mixture of warm soapy water and use a soft cloth or sponge to gently wipe down the window frames. Avoid using abrasive materials that could scratch the uPVC.
- Rinse and Dry: After wiping away the soapy residue, rinse the frames with clean water. Follow up by drying with a clean, non-abrasive cloth to remove any remaining moisture.
Keying the Surface
After cleaning, it is necessary to key the surface, which involves lightly sanding the window frames to improve the adhesion of the primer and paint:
- Sanding: Use 180 grit sandpaper to lightly sand the surface of the uPVC. This shouldn’t be too abrasive but just enough to create a slightly roughened texture.
- Remove Sanding Dust: Wipe away any dust from sanding with a tack cloth to ensure a clean surface for the primer to adhere to.
Once these steps are completed, your uPVC windows will be well-prepared for the application of primer, which is the next stage towards achieving the desired painting results.
Selecting the Right Paint
When painting UPVC windows, choosing the correct type of paint is essential for durability and a quality finish. Consider factors like the paint’s ability to bond with UPVC, resistance to weathering, and the final appearance it provides.
Types of UPVC Paint
- Water-based paint: Ideal for UPVC due to its quick drying time and low odour. Ensure you select a formula specifically designed for UPVC to guarantee proper adhesion and resistance to weathering.
- Oil-based paint: Not typically recommended for UPVC as it may not adhere well and can be prone to cracking due to the plastic’s expansion and contraction.
- Specialist UPVC paint: Look for products labelled as UPVC-specific. These are formulated to create a durable bond and resist UV damage, which prevents fading and discolouration.
Your choice should provide a smooth finish and be capable of handling the natural expansion and contraction of UPVC materials without cracking or peeling.
Choosing Colours
- Standard Colours: Common UPVC colours like white and brown are readily available. These colours reflect traditional aesthetics and tend to be more resilient to UV light.
- RAL Colours: For a wider selection, consider paints available in RAL colour codes. This system offers a palette of precise, standardised colours, giving you a broader range of options.
- Finish Options: Choose from gloss, eggshell, or a matte finish. Gloss finishes are highly reflective and easy to clean, whereas eggshell offers a subtle sheen and lower reflection.
Always test paint colours in a small area before fully committing, as the appearance can significantly vary under different lighting conditions.
Painting Process
Proper preparation and application techniques are critical components for successfully painting UPVC windows. This includes priming the frames to ensure solid paint adhesion and employing a methodical approach to achieve a smooth, even finish.
Priming UPVC Windows

- Apply at least two coats, letting the first coat dry thoroughly before applying the second.
- Top coat: A top coat may be necessary for additional protection, especially for windows facing extreme weather conditions.
By following these steps, ensuring each layer is dry before proceeding with the next, your painted UPVC windows will have a fresh, professional-looking finish.
Finishing Touches
Once you’ve applied the main coats of paint, focusing on the finer details ensures a professional look for your UPVC windows.
Details and Edges
When painting the details and edges of your UPVC windows, precision is key. Masking tape or painter’s tape is essential to achieve sharp lines and protect the glass and walls. Apply the tape carefully along the edges, pressing down to seal it. When painting:
- Use a smaller brush for control.
- Dab the brush onto the edges, avoiding excess paint build-up.
- Remove the tape while the paint is slightly wet to avoid peeling.
Top Tip: If you’re dealing with window putty, wait until the paint is completely dry before applying to avoid any unwanted mixing.
