How UPVC Spray Paint Works

uPVC (unplasticised polyvinyl chloride) windows and doors have gained popularity over the years due to their durability, energy efficiency, and low maintenance. However, the limitation of limited colour options has led to homeowners and businesses to explore uPVC spray painting as a cost-effective way to change or refresh the appearance of these fixtures. In this blog, we will explore how uPVC spray paint works and why it is crucial to use the right coating system and equipment to achieve a flawless factory finish. 

The Effectiveness of uPVC Spray Painting 

To put it simply, uPVC spray painting does work and offers a convenient way to transform the look of your uPVC windows and doors. Whether you want to change the colour entirely or update an existing one, uPVC spray painting can bring a fresh property. However, achieving a professional-looking finish requires precision and the right materials.

The Importance of Professional Application 

Spraying uPVC is not a task you can approach haphazardly. While it might be tempting to pick up a spray paint canister or use a spray painting gun, doing so will likely yield subpar results. To attain a factory-like finish that convincingly resembles the original manufacturing colour, a professional application using industrial-grade spray painting equipment is essential. 

The Science Behind uPVC Spray Paint Adhesion 

One of the critical factors in successful uPVC spray painting is ensuring proper adhesion between the paint and the uPVC surface. Traditional plastic paints that only adhere to the surface are prone to peeling, flaking, and cracking over time, mainly due to the presence of resins in uPVC that can bleed through the paint.

However, modern uPVC spray paints, such as those used by professional coating companies, create a molecular bond with the uPVC surface. These paints are specially designed to interact at a molecular level with the plastic, preventing any potential issues related to adhesion.

Long-lasting Results and Guarantees

When uPVC spray painting is done correctly using high-quality coatings that bond at a molecular level, the results are permanent and long-lasting. Reputable companies that offer professional uPVC spray painting services often provide guarantees for their work, typically lasting for up to 10 years. This level of confidence is a testament to the durability and effectiveness of the uPVC coating system.


uPVC spray painting can be a game-changer when it comes to transforming the appearance of your uPVC doors and windows. It offers an affordable and effective solution to change or refresh colours and revitalise the overall look of your property. However, to achieve a flawless factory finish and long-lasting results, it is crucial to rely on professional uPVC coating services that use high-quality spray paints designed to bond at a molecular level with the uPVC surface. 

If you are considering uPVC spray painting, it is best to consult with a reputable coating company that can guide you through the process and provide expert services to ensure your uPVC fixtures look impeccable for years to come. Remember, when done right, uPVC spray painting is a reliable and aesthetically pleasing option for enhancing the appeal of your property.
