While spray painting uPVC windows has its advantages, there are also some drawbacks to consider. One of the main cons is that the paint may not adhere well to the uPVC surface, leading to peeling or chipping over time. This can result in a less durable finish and may require touch-ups or repainting in the future. Additionally, spray painting can be a time-consuming and labor-intensive process, especially if you have multiple windows to paint. It requires careful preparation, including cleaning and priming the surface, as well as masking off surrounding areas to avoid overspray. Furthermore, if the windows are not properly prepared or if the paint is applied incorrectly, it can result in an uneven or streaky finish. Lastly, some homeowners may be concerned about the environmental impact of spray painting, as it involves the use of chemicals and aerosols. Most importantly, spray painting your windows will most likely void any remaining warranty or guarantee on your windows. It’s important to weigh these cons against the benefits before deciding whether spray painting uPVC windows is the right choice for you.
