Can You Paint UPVC Windows? The Short Answer
In short, yes you can paint UPVC windows, but it does take some preparation and the right materials.
UPVC, or unplasticized polyvinyl chloride, is a common, low-maintenance alternative to wood windows, but the plastic material can be difficult to paint. With the proper primer and paint, though, you can give your UPVC windows a whole new look.
Preparing UPVC Windows for Painting

So you want to give your UPVC windows a fresh coat of paint? It can be done, but you’ll need to put in some prep work first.
Cleaning and Lightly Sanding
First, wash the windows thoroughly with soapy water to remove any dirt or debris. Rinse well and let dry completely.
Then lightly sand the surface with fine-grit sandpaper (around 400 grit) to provide a tooth for the new paint to adhere to. Wipe away dust with a tack cloth.
Priming UPVC
Apply a coat of UPVC primer, letting it dry as directed. Priming is a must for UPVC since regular primers and paints won’t stick well to the smooth plastic surface. The primer creates a bonding layer for the paint.
Choosing UPVC-Friendly Paint
Use paint specifically meant for UPVC, like acrylic enamel, or check that your chosen paint is compatible with UPVC. Oil-based paints will not work. Do a test in an inconspicuous area first to ensure good adhesion.
Multiple Thin Coats
Apply 2-3 thin coats of paint, waiting for each coat to dry in between applications. Thinner coats adhere better than thick coats. Make sure to paint the edges and corners of the window for an even finish.
Finishing Touches
Once dry, you can reinstall any hardware or trims you removed. Add a top coat of sealant or varnish (also UPVC-friendly) for protection and durability. With the proper prep and products, your UPVC windows can get a flawless new look. The effort will be well worth it!
Choosing the Right Paint for UPVC Windows
To paint UPVC windows, you’ll need to choose a paint that’s specifically designed for plastics. Regular wall paint won’t adhere properly to the slick surface of UPVC and will likely peel off over time.
Plastic Paints
Look for paints labelled as “plastic,” “UPVC,” or “vinyl.” These are usually latex or acrylic paints that contain special adhesion promoters to help them grip onto plastics.
Popular brands include Zinsser, Rust-Oleum, and Krylon. You may need to do some light sanding to rough up the surface before painting, but in general, these paints are designed to stick to smooth plastics with minimal prep.

Within these paint types, you’ll also want to choose between:
➜ Primers – Primers are designed solely to provide adhesion for topcoats of paint. You’ll need to apply at least one topcoat after priming for best results. Primers typically come in light colours like grey.
➜ All-in-one paint and primers – These products contain both a primer and paint in one. They come in a range of colors so you may be able to complete your project in one coat. However, for the best durability, two coats are still recommended.
➜ Satin or eggshell sheens – Choose a paint with a satin, eggshell or semi-gloss sheen. Glossy paints won’t adhere as well and may highlight imperfections in the UPVC surface. Flat paints won’t provide good protection. A satin or eggshell paint provides good coverage with a durable yet smooth finish.
➜ Light colours – In general, lighter paint colours tend to adhere better to plastics. Dark colours may require an additional coat of primer to prevent the UPVC from showing through. White or cream shades are good versatile options for UPVC windows.
