How We Work
What is aluminium window spraying?
Aluminium window spraying is the professional application of specialist two-pack acrylic or polyurethane coatings directly onto existing aluminium window frames, curtain walling, and glazing system components, all carried out on-site, with frames remaining in place.
Unlike brush or roller application, spray application produces a factory-quality, high-build finish that is indistinguishable from a new powder-coated frame. The process involves thorough surface preparation, etch priming to ensure adhesion to non-porous aluminium substrates, and a final topcoat formulated for exterior durability and UV resistance.
The result is a permanent, professionally finished coating that extends the serviceable life of your aluminium windows by 15–20 years at a fraction of the cost of replacement, and with none of the building disruption.
How We Work
01
Survey & Specification
We assess substrate condition, existing coating type (powder coat, anodised, or painted), and specify the correct primer and topcoat system for your project.
02
Surface Preparation
Thorough cleaning, degreasing, and mechanical keying of all aluminium surfaces. Adjacent glazing and surrounding elements are carefully masked and protected.
03
Etch Priming
A specialist etch primer bonds chemically to the aluminium, overcoming the adhesion challenges of non-porous metal and providing a key for the topcoat.
04
Topcoat Application
High-build two-pack acrylic applied by HVLP spray equipment. Even, controlled coverage across all profiles, sills, frames, mullions, transoms, and reveals.
05
Quality Inspection
Film thickness measured, finish inspected for uniformity, masking removed. Full documentation provided for warranty and client records.
Why spray rather than replace?
For commercial property owners and facilities managers, the calculation is straightforward. Window spraying delivers a transformation that is visually identical to replacement, at 20–30% of the cost, with no building work and no interruption to operations.
Get a Free SurveyMinimal Disruption
We work in situ, so your building stays operational. Out-of-hours shifts, weekend access, phased sections: whatever it takes to keep tenants unaffected.
10-Year Guarantee
Our coating systems carry a comprehensive 10-year guarantee covering colour stability, adhesion, and finish integrity. Properly maintained coatings routinely exceed 15 years in service.
Environmentally Responsible
Recoating keeps the embodied carbon locked in your existing frames instead of sending them to landfill. No new aluminium manufactured, no old frames scrapped.
Any Colour, Any Finish
Full RAL Classic and RAL Design ranges, British Standard colours, and bespoke colour matching. Satin, gloss, and matt finishes available. Match existing frames or achieve a complete transformation.
Proven Durability
Two-pack acrylic systems built for external aluminium. Superior UV resistance, colour retention, and weathering performance. Finishes routinely last 15-20 years.
Aluminium window types we recoat
Not all aluminium window systems are alike. Our surveyors assess each substrate individually, identifying the existing coating type, surface condition, and specifying the appropriate primer and coating system for permanent adhesion.
Powder Coated Aluminium
The most common commercial window finish. Where the powder coat is sound and adhered, we can overcoat directly following mechanical preparation and priming. Ideal for colour changes and restoring faded or chalked finishes.
Anodised Aluminium
Anodised surfaces present adhesion challenges due to their non-porous oxide layer. Correct mechanical keying and specialist etch primers are essential. We have extensive experience coating both bronze and silver anodised systems.
Curtain Walling Systems
Large-scale aluminium curtain wall facades on commercial offices, educational buildings, and public sector properties. We work at height using appropriate access equipment and can phase works to maintain building envelope integrity.
Thermally Broken Frames
Modern thermally broken aluminium systems require careful handling around thermal break components. Our operatives are trained to work around these elements without compromising thermal performance.
Slim-Profile Systems
Crittall-style and other slim-profile aluminium window systems common in period commercial buildings and schools. Detailed spray application to fine profiles without masking failure or overspray onto glazing.
Composite & Mixed Systems
Buildings with a mix of aluminium windows, curtain walling, door frames, and shopfront elements can be completed in a single mobilisation, ensuring colour consistency across the entire building envelope.
The right colour, every time
We work from the complete RAL Classic range, RAL Design System+, and British Standard colour references. Popular commercial choices shown below, or we match any specified colour. Hover to identify.
Swatches are for reference only. Always specify from physical RAL or BS colour samples, screen colours vary by device.
Who We Work With
Built for commercial property professionals
Vanda Coatings works primarily with property managers, building owners, facilities management companies, local authorities, housing associations, and main contractors managing commercial refurbishment programmes.
Our commercial focus means we understand the constraints of occupied buildings, tenant considerations, health & safety requirements, phased access, and the need for detailed RAMS documentation. We carry full public liability and employer's liability insurance and can be added to approved contractor lists on request.

Everything you need to know about our aluminium window spraying service.
How long does aluminium window spraying last?
Our professionally applied coating systems carry a 10-year guarantee covering colour stability and adhesion. In practice, correctly specified two-pack acrylic systems on well-prepared aluminium routinely exceed 15–20 years in commercial environments, often outlasting original factory finishes on older buildings.
Can you spray aluminium windows without removing them?
Yes, this is the core advantage of professional on-site spraying. All work is completed with frames in-situ. We mask surrounds, protect glazing and surrounding surfaces, and apply the complete system on site. No removal, no building work, no reinstallation.
What surfaces can aluminium window spraying be applied to?
We can coat powder coated, anodised (bronze and silver), and previously painted aluminium. Each substrate requires a different preparation approach, our surveyors specify the correct primer system on inspection. Corroded or structurally compromised frames may require remediation before coating.
What colours are available?
We work from the full RAL Classic and RAL Design System+ ranges, over 2,000 options, as well as British Standard references and bespoke colour matching. The most requested commercial colours are RAL 7016 Anthracite Grey, RAL 9005 Jet Black, and RAL 9010 Pure White.
How much does aluminium window spraying cost?
Commercial pricing depends on area, access requirements, substrate condition, and coating specification. As a general guide, professional aluminium window spraying costs 70–80% less than full replacement. We provide detailed written quotations following a free site survey.
Do you provide method statements and RAMS documentation?
Yes. We provide full Method Statements, Risk Assessments, and Safe Systems of Work as standard for all commercial projects. We carry comprehensive public liability and employer's liability insurance and can supply documentation for contractor approval processes.
Can you work out of hours or at weekends?
Yes, we regularly schedule works outside normal business hours to eliminate disruption to tenants and building users. Out-of-hours scheduling is particularly common for occupied offices, retail environments, schools, and healthcare settings.
Do you cover the whole of the UK?
Vanda Coatings operates across mainland Britain from our base in Cardiff, Wales. We have completed projects across England, Scotland, and Wales for national property managers, facilities management companies, and local authorities. Contact us to discuss your specific location.
