Cladding spraying is the on-site application of a protective, decorative coating onto existing profiled metal cladding. Specialist sprayers clean, repair and recoat weathered panels in place, restoring colour and corrosion protection without removing a single sheet. It refurbishes a building envelope at a fraction of re-cladding cost.
Cladding spraying in brief
- What it is: on-site recoating of metal wall and roof cladding
- Where it's used: factories, warehouses, units, agricultural sheds
- What it fixes: faded colour, weathered coating, early corrosion
- Done in place: no panel removal, building stays in use
What Surfaces Can Be Sprayed?
Cladding spraying suits coated steel and aluminium panels, including plastisol, PVDF and polyester pre-finished cladding. Profiled wall sheets, flat composite panels and roof cladding all take a sprayed coating. The panel must be structurally sound, with corrosion limited to the surface rather than perforating the steel.
Plastisol is the most common substrate we respray. Metal wall cladding has been used across UK industrial estates since the 1970s, and high-build PVC coatings around 200 microns thick weather to a matt, faded finish over time [1]. That fading is the trigger for most spray refurbishments.
How Does Cladding Spraying Work?
The process runs in three stages: clean, prepare, coat. Operatives pressure-wash the panels, treat any cut-edge corrosion, then spray-apply a primer and topcoat by airless spray. The full method, access and drying sequence is covered in our guide to how cladding is sprayed on site, including weather windows and surface preparation standards.
Why Choose Spraying Over Replacement?
Spraying restores a tired building in days, not weeks, while it stays operational. As a refurbishment route, our professional cladding spraying service recolours and reseals the envelope on site, covering wall cladding, roof sheets and flashings in a single visit with minimal disruption to staff or production.
Cost is the other driver. Recoating typically lands well below re-sheeting, which is why most owners price spraying first. We break down the figures in our guide to how much cladding spraying costs, including the access, condition and area factors that move the rate per square metre.
Ready to Refurbish Your Cladding?
If your cladding looks faded, chalky or streaked with rust at the edges, it can almost certainly be sprayed rather than replaced. Get in touch for a free site survey and a fixed-price quote tailored to your building.
