STEP 01
Survey and defect mapping
Panels, fixings, laps, sealants, cut edges, flashings and water-ingress routes are assessed before a coating system is proposed.
TopSpray35 cladding refurbishment
Restore commercial cladding before replacement becomes unavoidable.
Survey-led repair, preparation and Prokol TopSpray35 protective coating for suitable industrial and commercial metal cladding. Restore colour, UV resistance and surface protection without pretending a coating can repair structural failure.
RAL colour options
Airless spray applied
Approved contractors
UK project support
TopSpray35 system position
UV-stable protection for suitable prepared cladding.
TopSpray35 is a two-component aliphatic polyurethane protective topcoat. It is not a standalone waterproofing membrane and must be specified over a confirmed, prepared and compatible substrate or system.
Application
Airless spray
Build-up
Minimum two coats
Colour
RAL range, confirmed
Warranty
25-year manufacturer route on qualifying installations
Warranty eligibility is project-specific and depends on substrate condition, preparation, complete build-up, application records and manufacturer acceptance.

The commercial problem
Faded cladding is rarely just a colour problem.
Chalking, UV degradation, open laps, failed sealants, corroded fixing lines and cut-edge deterioration can develop together. A useful refurbishment proposal separates cosmetic deterioration from defects that must be repaired before coating.
Factories and warehouses
Aged profiled metal elevations, loading bays and operational industrial buildings.
Retail and commercial units
Colour restoration and planned envelope maintenance across occupied assets.
Asset lifecycle extension
Protect suitable retained panels after the repair and preparation scope is completed.
Corporate colour change
Restore or change appearance using a confirmed RAL colour and trial panel.
A controlled refurbishment sequence
Coating is the final stage, not the first decision.
STEP 02
Repair before coating
Failed sealants, loose fixings, corrosion and damaged panels are treated, repaired or replaced as required by the survey findings.
STEP 03
Preparation and trial area
The existing finish is cleaned, prepared and tested. Primer and adhesion requirements are confirmed for the actual substrate and coating history.
STEP 04
TopSpray35 application
The confirmed system is airless-sprayed in a minimum of two coats, with RAL colour availability and application conditions agreed at specification stage.
Where refurbishment may work
- Faded, chalking or weathered factory-coated metal cladding
- Structurally sound profiled sheets requiring colour restoration
- Treatable surface corrosion at fixings, laps and cut edges
- Commercial elevations where repair and coating remain technically viable
Where coating is not the answer
- Perforated sheets or material loss that has compromised the panel
- Failed rails, brackets, fixings, insulation or structural support
- Widespread delamination where a sound coating substrate cannot be established
- Unknown finishes that cannot be tested or confirmed compatible
Cladding refurbishment enquiry
Send the elevation, defects and project location.
Include the building type, approximate elevation area, photographs, known panel finish and whether leaks, corrosion or failed sealants are present. The first step is determining whether a defensible refurbishment route exists.
