Paint spraying is a specialist refurbishment service that restores metal surfaces exposed to wear, UV degradation and weathering. At Structura UK we apply advanced on-site spraying techniques to breathe new life into aluminium and steel components such as curtain walling, entrance doors, window frames, copings, pressings and balustrades. Our approach uses industry-approved products and experienced spray teams to deliver durable, high-quality finishes with minimal disruption to building occupants.
Whether part of a planned maintenance programme or a standalone refurbishment project, our on-site paint spraying service is tailored to enhance appearance, prolong design life and support ongoing asset management.
Overview
Powder-coated and anodised finishes can deteriorate over time, showing signs of chalking, fading or surface defects. Rather than expensive replacement, professional on-site paint spraying is a cost-effective alternative that revitalises façades and metalwork to original or improved appearances. This service is available either on-site or off-site, using low-odour water-based paints that are suitable for occupied buildings and sensitive environments.
Typical applications include:
- Metal curtain walling and glazing frames
- Window and door frames
- Exterior architectural metalwork
- Copings, pressings, and balustrade systems
- Refurbishment of cladding and ancillary metal elements
How It Works
This process ensures every project is delivered to exacting standards with consistent results that align with architectural intent.
1. Initial Survey & Assessment
Our specialist team conducts a detailed site survey to assess surface conditions, identify corrosion, old coatings or contaminants, and determine the correct coating system. We record substrate types and environmental constraints to define a bespoke specification.

2. Preparation & Protection
Thorough surface preparation is essential. This typically includes cleaning, abrasion, removal of loose coatings, masking of adjacent finishes and installation of protective sheeting to safeguard surrounding areas.

3. Priming & Surface Treatment
Where required, we apply primer or corrosion-inhibitive treatments to enhance adhesion and extend coating life. This step is specified based on substrate type and exposure conditions.

4. Controlled Paint Spraying
Using professional spray equipment calibrated for consistency and finish quality, our teams apply the selected paint system. We control environmental factors such as temperature, humidity and ventilation to optimise cure and durability.

5. Quality Inspection & Touch-Ups
Once spraying is complete, we conduct a systematic inspection to verify film thickness, coverage and uniformity. Any minor imperfections are corrected before final approval.

6. Clean-Up & Site Handover
After completion, protective masks and coverings are removed, and the site is cleaned to leave a professional finish. We complete all documentation and quality sign-off with the client.

Frequently Asked Questions
What surfaces can be paint sprayed on site?
We work with a wide range of architectural metal surfaces including aluminium, steel curtain walling, window frames, balustrades and ancillary metalwork.
Is on-site paint spraying better than replacement?
In most refurbishment scenarios, paint spraying is a cost-effective method to restore appearance and performance without full replacement, significantly reducing waste and cost.
Can on-site spraying be done on occupied buildings?
Yes. We use low-odour, water-based systems that are suitable for occupied buildings and carefully manage site access and safety.
Do you offer colour matching?
Yes. We can match existing finishes precisely or provide colour updates to align with brand or design requirements.
How long does the new paint finish last?
Longevity depends on the coating system chosen, exposure conditions and maintenance. We specify systems for durability and provide guidance on care.
Will the process disrupt building operations?
Our teams plan work in phases to limit disruption. Noise, odour and access impacts are minimised wherever possible.
Do you provide warranty or aftercare support?
We provide documented specifications and maintenance advice. Warranty terms depend on the chosen paint system and supplier.
