uPVC Spray Painting Guide: How Windows, Doors and Frames Are Sprayed

Illustrative stock photo. This is not a ColourHaus project.

uPVC spray painting changes the colour of your existing windows, doors, fascias, soffits and conservatory frames without taking them out. The surfaces are cleaned and degreased to remove chalking and dirt, the glass, seals and hardware are masked, and a coating made for uPVC is sprayed on in even coats. ColourHaus uses Kolorbond-certified coatings, which bond to the uPVC rather than sitting on top like ordinary paint, and gives a 10-year guarantee. Windows cost £80 to £150 each, and most projects take one to two days.

This guide explains how the work is done, surface by surface. If you are still deciding whether to spray at all, read is uPVC spray painting worth it? For the money side, see uPVC spraying versus window replacement costs. Our uPVC spray painting service page has prices and booking details.

What Is uPVC Spray Painting?

uPVC (unplasticised polyvinyl chloride) is used for windows, doors and exterior trim because it does not rot and needs little upkeep. Over the years, though, sun and weather leave white uPVC chalky, yellowed or grey. Spraying puts a new, even colour over the existing frames using spray equipment, so the result is smooth with no brush marks. Done properly, from normal viewing distance it is hard to tell the frames have been sprayed rather than replaced.

The key word is properly. Ordinary paints and primers do not bond well to uPVC, so the wrong product or poor preparation leads to peeling. That is why the coating system and the preparation matter more than anything else.

Which uPVC Surfaces Can Be Sprayed?

Windows

Casement, tilt-and-turn, bay and fixed windows can all be sprayed, including sills, mullions and transoms. The glass and seals are masked throughout. You can spray just the outside, or the inside as well if you want the frames to match a room. Windows cost £80 to £150 each.

Front, back and French doors

uPVC doors are sprayed in place with handles, letterboxes, hinges and glazed panels masked. A uPVC door costs £200 to £350. For front doors, including composite doors, see our front door spraying service, which starts from £200 for a standard uPVC or composite door.

Fascias and soffits

Fascias are the boards behind the gutters and soffits are the boards under the eaves. They are often sprayed with the windows as part of a whole-house package, typically £2,000 to £5,500 for windows, doors, fascias and soffits together.

Conservatories

Conservatory frames, door frames and uPVC trim can be sprayed; the glass and polycarbonate roof panels cannot. Conservatories are quoted after a survey. Our article on spraying a uPVC conservatory covers it in detail.

Garage doors

Garage doors are often done at the same time as the windows so the colours match. Our garage door spraying service starts from £150 for a single up-and-over door.

Why uPVC Needs Specialist Preparation and Coatings

uPVC is a low-energy surface: liquids tend to sit on it rather than wetting it out, a bit like water beading on a waxed car. Ordinary paint can look fine at first and then lift once it has been through some weather. Kolorbond is a coating system made for uPVC and other plastics that bonds to the surface rather than sitting on top of it.

Cleaning matters just as much. Over the years uPVC collects traffic film, chalking and grease around handles. Anything left on the surface stops the coating bonding at that spot, which is where peeling starts.

The Process, Step by Step

1. Survey. We check every frame, the glazing and the mechanisms, talk through colours with samples, and send a fixed-price written quote within 48 hours. If a window needs replacing rather than spraying, we say so.
2. Masking. Glass, seals, hardware, brickwork and sills not being sprayed are covered with masking film and tape for clean, sharp edges.
3. Cleaning and degreasing. Chalking, dirt and grease are removed completely. This takes time and is not skipped.
4. Spraying. The Kolorbond-certified coating is sprayed on in even coats with HVLP (high volume, low pressure) equipment, which gives fine atomisation and less overspray.
5. Unmasking and checks. Masking comes off, edges are checked and touched in, and the area is cleaned up.
6. Sign-off. We go over the work with you and issue your written guarantee.

Most uPVC projects take one to two days, and a whole-house package typically two to three. Frames stay in place, so your home stays secure and usable throughout.

Colours

Any colour in the RAL Classic range can be sprayed, and our colour matching service can match other references, such as a new composite door or an existing window. Brown, cream and other coloured uPVC can be resprayed, as well as white. Popular choices include:

• RAL 7016 Anthracite Grey: a dark, blue-toned grey that suits red brick, buff brick, stone and render.
• RAL 9005 Jet Black: strong and smart, especially on Victorian and Edwardian houses.
• RAL 6005 Moss Green: a deep green that sits well with Yorkshire stone.
• RAL 5011 Steel Blue: a very dark blue with a traditional feel.
• RAL 9001 Cream: softer than white on cottages and period houses.
• RAL 8022 Black Brown: a very dark brown that suits brown or terracotta brick.

The Guarantee and How Long It Lasts

Using Kolorbond-certified coatings is what allows us to give a 10-year guarantee on uPVC, backed by the manufacturer for colour stability and adhesion. The full terms are on our guarantee page. How long the finish lasts beyond that depends on:

• Preparation: the biggest single factor.
• Exposure: south-facing frames get more sun and usually show wear before north-facing ones.
• Colour: dark colours absorb more heat than light ones.
• Cleaning: gentle, regular cleaning helps; harsh products and close-range pressure washing do not.

Our article on how long uPVC spray painting lasts in Yorkshire weather goes into more detail.

“I've had my white uPVC bay windows sprayed grey and they've done a great job. The paint looks just like a factory finish and totally transformed the house.”

“Matt painted all the windows, soffits, fascias, garage and gates of our house. A big job, and despite the awful weather he got it done with great suggestions.”

Questions to Ask Any uPVC Sprayer

• Which coating system do you use on uPVC, and is it made for plastics? A sprayer should be able to name it.
• Is the guarantee in writing, how long is it and what does it cover?
• Can I see or read about jobs you did a few years ago? Fresh work always looks good; work that has been through a few winters tells you more.
• Are you insured? Spraying outdoors carries a risk of overspray onto cars or neighbouring property.
• What is masked, and how? Glass, seals, hardware and brickwork should all be protected.

ColourHaus has been spraying uPVC across Yorkshire since 2015 from our workshop in Sheepscar, Leeds. You can read what customers say on our reviews page and check our accreditations and insurance. In Leeds, see uPVC spray painting in Leeds.

Looking After Sprayed uPVC

• Clean with warm water, a little washing-up liquid and a soft cloth or sponge.
• Avoid abrasive products, scouring pads and solvent-based cleaners.
• Don't aim a pressure washer at close range at frame edges or joints.
• Look over the frames once a year and tell us about anything that concerns you while the guarantee is running.
