Can You Paint uPVC Trim Black?

When it comes to home improvement projects, uPVC trim has gained immense popularity due to its durability, low maintenance requirements, and versatility. uPVC (unplasticized polyvinyl chloride) trim is a synthetic material widely used for exterior and interior applications such as window trims, door surrounds, and fascia boards. While uPVC window trim comes in a variety of colours, homeowners often wonder whether they can paint uPVC trim black to achieve a different aesthetic. In this blog post, we’ll explore the possibilities, considerations, and best practices for painting PVC trim black.

Understanding PVC Trim

uPVC trim is known for its exceptional qualities. It is resistant to moisture, rot, insects, and other environmental factors that commonly affect wood trim. Additionally, uPVC trim does not warp, crack, or fade over time, making it a long-lasting choice for various applications.

Painting PVC Trim

Yes, you can indeed paint uPVC trim black, and many homeowners choose to do so to achieve a sleek and modern look. However, there are a few important points to consider before diving into this project:

Choose the Right Paint

Not all paints are suitable for uPVC trim. It’s recommended to use a high-quality acrylic latex, paint formulated for exterior use. Acrylic latex paints offer good adhesion, flexibility, and resistance to UV rays, which is essential for a lasting finish on uPVC trim.

Surface Preparation

Proper surface preparation is crucial for achieving a smooth and long-lasting paint job. Clean the PVC trim thoroughly to remove any dirt, grease, or mildew. You might consider using a mild detergent and water or an especially formulated uPVC cleaner. Rinse the trim well and allow it to dry completely before proceeding.


While some high-quality paints claim to adhere well to uPVC surfaces without a primer, using a primer designed for uPVC can enhance adhesion and durability. A primer can also help block stains and provide a consistent base for the paint. 

Choosing the Right Colour

Black is a popular choice for a bold and elegant look. However, keep in mind that darker colours, including black, can absorb more heat from the sun, potentially causing the uPVC trim to expand more than usual. This thermal expansion can affect the paint’s adhesion and longevity, so it’s crucial to choose a paint with excellent expansion and contraction properties.


When applying the paint, use a high-quality synthetic bristle brush or a roller designed for smooth surfaces. Apply thin and even coats, allowing each coat to dry completely before applying the next. Avoid applying heavy coats of paint, as they can lead to drips and uneven drying.


While PVC trim is low-maintenance, painted surfaces may require touch-ups over time, especially in areas exposed to harsh weather conditions. Regular inspections and minor touch-ups can help extend the life of the paint finish.
