Is spray painting UPVC windows any good?

Spray painting uPVC (unplasticized polyvinyl chloride) windows is a common practice for those looking to change the colour of their window frames or refresh the appearance of aging uPVC surfaces. However, there are important considerations to keep in mind:


  1. Aesthetics: Spray painting allows you to update the colour of your uPVC windows, giving your home a fresh and modern look without the cost of replacing the entire window frame.

  2. Cost-Effective: Painting uPVC windows is generally more budget-friendly than replacing them. It can be a cost-effective way to enhance curb appeal.

  3. DIY Option: With the right tools and preparation, some homeowners choose to paint their uPVC windows as a do-it-yourself project, potentially saving on labour costs.


  1. Surface Preparation: The success of spray painting uPVC windows depends significantly on proper surface preparation. The uPVC surface must be thoroughly cleaned and, in some cases, lightly sanded to promote adhesion.

  2. Quality of Paint: Use a high-quality paint specifically formulated for uPVC surfaces. This type of paint is designed to adhere well to uPVC and withstand outdoor conditions. Do not use regular paints or primers that may not adhere properly.

  3. Colour Selection: Dark colours absorb more heat, which can lead to uPVC warping or distortion if you use the wrong product or an off the shelf paint.

  4. Weather Conditions: Ideal painting conditions include mild temperatures and low humidity. Avoid painting on extremely hot or cold days, as this can affect the paint application and drying process.

  5. Longevity: While spray-painted uPVC can look good initially, the long-term durability will depend on the company you use and the product used. We at uPVC Kolortech use a professional paint which allows us to provide you with a 10 years guarantee.
