Before and After: Transforming White uPVC with Colour

Discover how painted uPVC windows, doors, and trims can completely change the look of a property. In this guide, real examples show how uPVC paint upgraded a plain white finish using modern, long-lasting colour—with straightforward preparation and the right products.

Why Change White uPVC?

White uPVC is standard, but not always desirable. Over time, it can look tired, clash with updated brickwork or render, and limit curb appeal. Whether you’re matching new colours on exterior walls or simply refreshing a dated style, uPVC paint offers a cost-effective upgrade without replacing the units.

Customers often repaint uPVC to:

Match newly painted masonry
Introduce contrast for modern or heritage schemes
Fix yellowing or ageing surfaces
Avoid full window or door replacements

Choosing the Right Products and Colours

Not all paints are suitable for uPVC. It’s essential to use specialist adhesion primers and topcoats designed for plastics exposed to UV and weather. Popular product options include:

Kolorbond uPVC Paint – Specifically designed for plastic substrates
Zinsser AllCoat Exterior Satin or Gloss – Available in BS, RAL, and NCS colours
Bradite One Can – A convenient all-in-one primer and finish

Colour choices vary by property style. Some of the most requested include:

Anthracite Grey (RAL 7016) – Popular colour for modern upgrades or industrial looks
Chartwell Green – Suited to period homes and cottages
RAL 7035 Light Grey – Clean, contemporary, and bright without being white

Surface Preparation and Painting Process

Preparation is the difference between success and failure when painting uPVC.

Clean the Surface Thoroughly
Remove all grease, dirt, and mould using a degreasing cleaner. Abrade lightly with a fine sanding pad to create a key.
Mask Surrounding Areas
Protect glass, brickwork, and handles with tape and sheeting.
Apply Adhesion Primer
If using a system that requires it, apply a plastic primer and allow the full curing time.
Topcoat in Ideal Conditions
Apply the paint in dry, mild weather. Two coats are typical, using a brush, roller, or spray.

Questions from Readers

Can you paint white uPVC brown, black, or grey?

Yes. Specialist uPVC paints are available in thousands of colours, including popular shades like Anthracite Grey, Black, and Chartwell Green. These paints offer solid coverage even over bright white, and darker colours can give a more contemporary or bold finish.

Can I paint uPVC gutters, soffits, or cladding too?

Yes. The same specialist systems used on doors and windows can be applied to uPVC cladding in thousands of colours, as well as to fascia boards, downpipes, and soffits. Make sure to clean off all dirt, algae, and oxidation first, and use appropriate access equipment where necessary.

Does the paint peel or crack over time?

If the correct preparation and products are used, the paint should not peel, flake, or crack. Proper cleaning, light abrasion, and priming (where required) help the coating bond to the plastic. Most systems provide protection for 5–10 years depending on exposure and quality of application.

Can I use any paint on uPVC?

No. uPVC is a low-energy surface, meaning regular masonry, wood, or metal paints will not stick properly. Only use coatings made specifically for plastics. These often include adhesion promoters or are formulated to grip directly to smooth plastic surfaces.

Do I need to sand uPVC before painting?

Yes, a light keying is important. Use a fine sanding pad or abrasive sponge to scuff the surface. This helps primers and topcoats bond more effectively, even if the surface looks clean. Don’t skip this step—it improves long-term durability.

What’s the best time of year to paint uPVC?

Late spring through early autumn is ideal. Choose dry, mild days—ideally between 10°C and 25°C. Avoid painting in direct hot sunlight, very cold temperatures, or when rain is expected. Early morning or late afternoon works best on warm days.

Can I paint over old uPVC paint?

Yes, if the existing paint is sound and not flaking or lifting. Clean the surface, abrade it lightly, and recoat using a compatible system. If the old paint is unknown, test a small patch first or consider priming to ensure compatibility.

Will the finish look brush-marked?

It depends on the product and application method. Many uPVC paints are self-levelling, giving a smooth result by brush or roller. For a spray-like finish, use foam rollers or airless spray. Follow the drying times and instructions for best results.
