uPVC Spraying
Windows, doors and frames sprayed to change or refresh their colour, without replacing the uPVC underneath.
About uPVC Spraying
The short answer
RS Spray Decor sprays uPVC windows, doors, frames, fascias and trims across Surrey and south-west London, refreshing a faded or chalked finish or changing the colour entirely without replacing the frames. uPVC is prepared and coated differently to render, timber or masonry, using an adhesion promoter and a solvent-based two-part coating suited to the material so the finish keys into a naturally slick surface and stands up to UV without fading. Free, no-obligation quotes.
uPVC windows, doors, frames and other exterior uPVC features can be professionally prepared and sprayed to refresh their appearance or change their colour, using preparation and coatings suited to the material rather than treated the same as render, timber or masonry.
uPVC is manufactured to be smooth and low-maintenance, which is precisely what makes it difficult for a coating to grip if the surface is not properly degreased, abraded and primed with an adhesion promoter built for the material. That preparation is what decides whether the finish is still holding on in three years or peeling at the edges within one.
It is a genuine alternative to replacing frames that are still structurally sound but have faded, chalked or simply gone out of style. A full colour change, from white to anthracite or another modern shade, is possible without the cost or disruption of new windows and doors.
The topcoat itself is a proper solvent-based two-part paint rather than a one-part system, and that difference is what shows up years later. The adhesion and durability are considerably stronger than any one-part product, and the finish is highly resistant to UV damage, so the colour does not start fading after a few years in the sun the way a lesser coating would.
Glass, seals, ironmongery and the surfaces around every frame are masked off before spraying starts, so the finish lands only where it is meant to.
What it covers
- Window frames and sashes
- Doors, door frames and thresholds
- Fascias, soffits and bargeboards in uPVC
- Conservatory frames
- Garage doors and outbuildings in uPVC
- Colour change without replacing the frames
What it suits
- Sound uPVC that is structurally fine but has faded, chalked or yellowed with UV exposure

The uPVC-specific service: colour and finish rather than replacement, on a substrate that needs its own preparation and coatings.
Before any finish goes on
- 01
The surface gets identified as uPVC first, because it takes a different preparation route to render, timber or masonry, and treating it like any of those is why a sprayed finish on uPVC lets go early.
- 02
uPVC is degreased and washed down. Window and door frames collect airborne grime, algae and general weathering that sits on a naturally slick surface and stops a coating keying properly if it is left on.
- 03
The factory finish is abraded to give the coating something to grip, since uPVC is manufactured to be smooth and low-maintenance, which is exactly what makes it hard for paint to bond to untreated.
- 04
An adhesion promoter suited to uPVC goes on before the topcoat. Skipping this step, or using a standard exterior primer instead, is the most common reason a uPVC respray fails within a year or two.
- 05
Glass, seals, ironmongery, brickwork and render around the frames are masked off, and any trickle vents or hardware that should not be coated are covered or removed.
How a uPVC spraying job runs
- 01
Look at the frames
In person or from photos, to establish the condition of the uPVC and whether it is a genuine candidate for spraying rather than replacement.
- 02
Quote and colour choice
A written quote with the colour agreed against a RAL reference or sample before anything is ordered.
- 03
Wash down and mask
Frames washed down to remove grime and algae, then glass, seals, ironmongery and surrounding surfaces masked off.
- 04
Abrade and prime
The factory finish keyed, dust removed, then an adhesion promoter suited to uPVC applied before anything else goes on.
- 05
Spray
Coatings built up in even coats specified for uPVC, rather than treating the frames as another exterior surface.
- 06
Cure and check
Coatings left to harden, masking removed, and every frame checked before the job is signed off.
What you get to choose
- A solvent-based two-part coating specified for uPVC, not a standard one-part exterior masonry or timber system, chosen for adhesion and durability that a one-part paint cannot match
- An adhesion promoter suited to uPVC, applied before the topcoat
- Colour matched to a RAL reference, an existing scheme, or a sample you supply
- Sheen chosen to suit the property, from a factory-style finish through to something with more depth
- A finish that resists UV damage, so the colour holds rather than fading after a few years in the sun
Where this is not the right job
- A sprayed finish changes colour and refreshes the surface. It does not fix cracked, warped or failed uPVC, or worn seals and gaskets, which need addressing on their own terms first.
- Very heavily degraded or chalked uPVC can often be brought back with the right preparation, but where the material itself is failing rather than just tired-looking, replacement is the more honest answer, and that gets said at the quote stage.
- Like any exterior coating, it needs a dry surface and a sensible temperature to go on properly, so work is scheduled around the weather.
- Kitchen, Cabinet and Joinery ResprayingThe specialist service: spraying existing cabinetry and joinery so it looks renewed without being replaced.
- Professional DecoratingRoom-by-room interior work, where the preparation and the woodwork matter as much as the wall colour.
- Interior and Exterior PaintingProperty-scale painting, and the outside of the building - where the substrate and the weather set the rules.
- Commercial DecoratingWork in premises that have to keep functioning, where sequencing matters as much as the finish.
- WallpaperingPaper rather than paint - where the wall underneath and the pattern repeat decide the result.

uPVC Spraying questions
Can uPVC windows and doors actually be sprayed?
Yes, provided the uPVC is sound. It needs preparation built for the material rather than a standard exterior system: degreasing, abrading the factory finish, and an adhesion promoter suited to uPVC before any topcoat goes on. Skip that and the coating lets go early, whatever colour is on top of it.
Why does uPVC need different preparation to render or timber?
uPVC is manufactured to be smooth and low-maintenance, which is exactly what makes it hard for a coating to grip. Render and timber are porous and take a standard exterior primer; uPVC is not, and needs its factory finish keyed and an adhesion promoter made for the material rather than one chosen for masonry or wood.
Can you change the colour of white uPVC frames?
Yes. Anthracite, grey and other colour changes are common, whether the frames have simply gone out of style or a repainted exterior needs the windows and doors to match. It is a full colour change rather than a tint, matched to a RAL reference, an existing scheme or a sample you supply.
Is spraying cheaper than replacing uPVC windows and doors?
Usually, yes, where the frames are still structurally sound. It is a genuine alternative to full replacement when the uPVC itself is fine and only the finish has faded, chalked or gone out of style, at a fraction of the cost of new windows and doors.
What condition do the frames need to be in?
Sound uPVC that is structurally fine but faded, chalked or discoloured from UV exposure is the usual candidate. Cracked, warped uPVC or failed seals are a different problem that paint does not fix, and very heavily degraded frames are sometimes better replaced than sprayed, which gets said honestly at the quote stage rather than after the work starts.
How long does a sprayed uPVC finish last?
Properly degreased, keyed and primed with an adhesion promoter built for uPVC, and finished with a solvent-based two-part paint rather than a one-part product, a sprayed finish holds up well to UK weather. That two-part coating has adhesion and durability that a one-part paint cannot match, and it is highly resistant to UV damage, so the colour keeps its depth instead of starting to fade after a few years in the sun.
What paint do you use on uPVC?
A proper solvent-based two-part paint, not a one-part system. The two-part coating bonds harder and lasts longer than any one-part alternative, and it stands up to UV exposure without the colour fading the way a cheaper finish would after a few years outdoors.
Do you spray the glass as well?
No. Glass, seals, ironmongery and the brickwork or render around every frame are masked off before spraying starts, along with trickle vents and any hardware that should not be coated, so the finish lands only on the uPVC.
Can fascias, soffits and garage doors be sprayed too?
Yes. Fascias, soffits, bargeboards, conservatory frames and garage doors in uPVC are all sprayed the same way, with the same preparation and adhesion promoter as window and door frames.
Does the work have to happen in dry weather?
Yes. Like any exterior coating, uPVC spraying needs a dry surface and a sensible temperature to cure properly, so work is scheduled around the weather rather than pushed through a wet or cold spell.
Can you match an existing scheme or a RAL colour?
Yes. Colour is agreed against a RAL reference, an existing exterior scheme, or a sample you supply, and confirmed before anything is ordered so there is no ambiguity on the day.
