UPVC Windows & Doors Spraying

Don't replace brown or white UPVC — respray it. Colour-fast, wipe-clean finishes in any RAL shade, guaranteed for 10 years, done in a day per elevation.

Replacing serviceable windows to change their colour is expensive, wasteful and slow. UPVC spraying from AT Precision Coatings gives you the colour you actually want — inside and out — in a day per elevation, for roughly a third of the cost of new frames.

The secret is chemistry, not paint. Plastic substrates expand, contract and shrug off ordinary coatings, so we use adhesion-engineered primers and flexible 2K topcoats developed specifically for UPVC, ASA and composite skins. Applied by sprayers who mask to razor lines, the finish looks like a factory-coloured frame — because chemically, it performs like one.

Dual-colour schemes, conservatory roof transformations and full house-lot programmes are our daily work. Every job is backed with a 10-year guarantee against flaking, peeling and discolouration — the three things that never happen when the system is right.

Questions, answered

Does spraying UPVC really last?
With the correct primer and 2K flexible topcoats, yes — we guarantee the finish for 10 years. The systems are the same chemistry used on automotive bumpers.
Can windows be open during spraying?
Frames are sprayed closed for a continuous film, then opened after the flash-off window. We sequence around ventilation needs.
Can you do a different colour inside and out?
Yes — dual-colour is popular: anthracite outside with white inside keeps interiors bright.
What about composite and aluminium doors?
We coat composite skins, aluminium profiles and even garage doors with systems matched to each substrate.
How should I clean sprayed frames?
A soft cloth and mild soapy water twice a year. No abrasives, no solvent cleaners.
