Specialist UK Manufacturer · Industrial Roof Refurbishment
Effective refurbishment starts with diagnosis.
Refurbishment works best when the defect is understood before the system is selected.
Core Philosophy
Knowledge before products.
Understand the condition
Industrial roofs, gutters and cladding rarely fail in one uniform way. Different defects, substrates and junctions can exist within the same area, so the condition needs to be understood before a refurbishment approach is chosen.
Match the system to the problem
The most appropriate system depends on the defect, its cause, the substrate and the required outcome. Product selection should follow the condition, not lead it.
Condition-Led Categorisation
Systems matched to the condition
Different defects call for different approaches. Liquasil systems are designed around the substrate, exposure and refurbishment requirement rather than a one-size-fits-all solution.
Metal roof refurbishment
Protective coating systems for ageing profiled metal roofs, including specification-grade and practical refurbishment options.
Cut edge corrosion
A dedicated treatment for corrosion at sheet edges and laps, designed to deal with one of the most common failure points on metal roofs.
Gutters
Specialist systems for fully bonded lining and refurbishment of metal gutters, helping protect against leaks and extend service life.
Cladding
Durable coating systems for the refurbishment and protection of external metal cladding on industrial buildings.

About Liquasil
Specialist systems. Practical technical support
Liquasil develops specialist refurbishment systems for industrial roofs, gutters and cladding, supported by practical specification guidance and direct technical access.
The approach is simple: understand the condition, select the appropriate system and support the project through specification, application and inspection.
Technical Workflow
A structured route to specification.
Clear technical support from initial appraisal through to application.
Step 01
Assess the condition
Site information, photographs and inspection findings are reviewed to understand the substrate, defects and likely causes before a refurbishment system is considered.
Step 02
Develop the specification
The appropriate system is selected to suit the actual condition of the roof, gutter or cladding, with preparation, primers, detailing and application requirements clearly defined.
Step 03
Support the application
Technical support is available before and during the project, with site inspections where required to help maintain the specification through to completion.

Liquasil's defects first approach
Industrial refurbishment rarely starts with a perfect substrate. Real projects involve corrosion, failed coatings, ageing gutters, difficult details and previous repairs.
Industrial roof refurbishment: Existing condition, previous repairs and roof details all influence the specification.
Hidden defects: Corrosion can develop within laps even when the exposed roof surface appears serviceable.
Gutter condition: Standing water, failed joints, previous repairs and substrate deterioration need to be understood before a lining system is specified.
