Professionally sprayed uPVC lasts ten years or more when prepared and coated correctly. The finish will not peel or flake if a PVC-specific primer and UV-stable topcoat were used over a properly cleaned, keyed surface. Aftercare is simple: wash occasionally with mild soapy water and avoid solvent or abrasive cleaners.
Longevity is the question behind every respray decision — nobody wants a finish that looks superb for a summer and fails by year three. Here is the honest picture of what determines lifespan, and the small things you can do to extend it.
What a ten-year finish is made of
Three things, in order of importance: preparation, primer, topcoat. Preparation removes everything that stops adhesion — grease, silicone polish residue, oxidised chalky surface. The primer is chemistry: it forms a molecular bond with rigid PVC that ordinary paints simply cannot. The topcoat then provides colour, UV resistance and flexibility, moving with the frame through seasonal expansion rather than cracking.
What shortens coating life
Almost every failed spray job we are asked to rescue shares the same story: general-purpose paint applied over inadequate preparation. No PVC primer, silicone residue left on the frame, or thick brushed coats that bridge moving joints and crack. The product system and the preparation discipline are the whole game — which is why we specify both in writing on every quote.
Aftercare: genuinely simple
Wash the frames once or twice a year with warm soapy water and a soft cloth — exactly as you would factory-coated frames. Avoid solvent cleaners, abrasive creams and pressure-washing at close range. Check external mastic seals as part of normal home maintenance. That is the entire list.
Our guarantee
We back window and exterior resprays with a 10-year manufacturer’s guarantee covering peeling, flaking and adhesion failure. It is worth noting what makes that guarantee possible: we simply do not skip preparation, and we only use coating systems with a track record measured in decades.
Frequently asked questions
Will sprayed uPVC peel?+
Not when properly prepared and primed with a PVC-specific system. Peeling is the signature of skipped preparation or wrong products — both covered against by our guarantee.
Does the colour fade?+
UV-stable topcoats hold colour extremely well. Expect no meaningful fade within the guarantee period, even on south-facing elevations.
Can I clean sprayed frames like normal uPVC?+
Yes — mild soapy water and a soft cloth. Avoid solvents and abrasives, which no coated or factory finish likes.
Can a damaged area be repaired?+
Yes — localised damage can be prepared and re-sprayed to blend with the surrounding finish, one of spraying's underrated advantages.
