How To Paint White UPVC Windows Grey

Painting white UPVC windows grey can breathe new life into your home’s exterior, providing a modern and refreshed look. Follow these step-by-step instructions to achieve a professional finish:

Clean the Surface

Begin by thoroughly cleaning the UPVC surface to remove any dirt, grime, or grease. Use a mild detergent solution and a sponge or cloth to scrub the windows clean. Rinse off the detergent with water and allow the windows to dry completely before proceeding.

Prepare the Area 

Protect the surrounding areas from paint splatter by covering them with drop cloths or plastic sheeting. Mask off any areas you don’t want to paint, such as the glass panes and adjacent walls, using painter’s tape.

Sand the Surface

Lightly sand the UPVC surface with fine-grit sandpaper to create a rough texture for better paint adhesion. Be careful not to sand too aggressively, as UPVC can be easily damaged. Wipe away any dust with a clean, damp cloth.

Prime the Surface

Apply a suitable primer designed for use on UPVC surfaces. This will help the paint adhere better and provide a more durable finish. Use a brush or roller to apply the primer evenly, following the manufacturer’s instructions regarding drying times.

Choose the Right Paint

Select a high-quality paint specifically formulated for use on UPVC. Opt for a grey shade that complements your home’s exterior colour scheme. Satin or semi-gloss finishes are often preferred for their durability and ease of cleaning.

Apply the Paint

Once the primer has dried completely, it’s time to apply the grey paint. Stir the paint thoroughly before use and apply it evenly with a brush or roller, working in smooth, overlapping strokes. Take care not to apply too thickly to avoid drips or runs.

Allow to Dry and Cure

Allow the first coat of paint to dry completely before applying additional coats. Follow the manufacturer’s recommended drying times between coats, typically a few hours. Depending on the paint and desired coverage, you may need to apply two or more coats for full opacity.

Finish and Seal

Once the final coat has dried, inspect the windows for any uneven areas or missed spots. Touch up as needed, then remove the painter’s tape carefully. Allow the paint to cure fully according to the manufacturer’s instructions before reattaching any hardware or opening and closing the windows.

By following these steps carefully and using the right materials, you can successfully paint white UPVC windows grey and achieve a professional-looking finish that enhances the overall appearance of your home’s exterior.

Things To Consider

Before starting the process of painting your white UPVC windows grey, there are several important factors to keep in mind to ensure a successful outcome. Firstly, consider the climate and weather conditions in your area, as extreme temperatures or humidity levels can affect the drying and curing times of the paint. Additionally, assess the condition of your UPVC windows to determine if any repairs or maintenance work is needed before painting. It’s essential to use the right type of paint and primer specifically formulated for UPVC surfaces to ensure proper adhesion and durability.

Moreover, take into account any architectural or design elements of your home’s exterior and choose a grey shade that complements the overall aesthetic. Proper surface preparation, including cleaning and sanding, is crucial for optimal paint adhesion and longevity. Lastly, consider your skill level and the time and effort required for the painting project, as well as any safety precautions necessary when working at heights or with ladders. By carefully considering these factors, you can ensure a smooth and successful painting process for your UPVC windows.


In conclusion, transforming your white UPVC windows to a stylish grey hue can significantly change the overall aesthetic of your home’s exterior. By following the step-by-step instructions and considering important factors such as climate, surface preparation, and paint selection, you can achieve professional-looking results that endure the test of time.
