Metalseal vs Liquasil Lite: Choosing the Right Roof Coating System
Selecting the appropriate roof coating system depends on the condition of the roof, the objectives of the project, and the level of assurance required.
Metalseal and Liquasil Lite are both silicone-based roof coating systems designed for the refurbishment of industrial roofs.
However, they are intended for different types of projects and should not be considered interchangeable.
The selection of the correct system depends on the condition of the roof, the objectives of the project, and the level of assurance required.
This comparison outlines the key differences to assist in selecting the correct system.
Specification-led system designed for projects requiring certification, long-term performance, and controlled application.
- BBA Approved
- 25-year system guarantee
- Designed for specification and dilapidations projects
- Includes cut edge corrosion treatment as standard
- Installed by approved contractors under controlled conditions
Practical, cost-effective system suited to contractor-led and budget-driven projects.
- Non-BBA system
- Cost-effective alternative where certification is not required
- Suitable for metal and asbestos roofs
- Simple, accessible application
- Available for contractor-led refurbishment works
Criteria
- Intended Use
- Certification
- Guarantee
- Application
- Cut Edge Treatment
- Substrate Suitability
- Specification Use
Metalseal
- Specification-led refurbishment
- BBA Approved & BRoof(t4)
- 25 Years
- Controlled, approved installers
- Included as standard
- Metalroofs
- Suitable for formal specifications
Liquasil Lite
- Contractor-led / budget projects
- BRoof(t4) fire rated
- Project-dependent
- More flexcible application
- 2 options available
- Multiple substrate types
- Typically open-specification
The choice between systems is not based on performance alone, but on the level of assurance required for the project.
When Metalseal is typically appropriate
- Projects requiring third-party certification
- Dilapidations or formal refurbishment schemes
- Long-term asset management strategies
- Where defects extend beyond surface-level corrosion
- Where specification control and risk management are critical
When Liquasil Lite is typically appropriate
- Budget-driven refurbishment projects
- Contractor-led works
- Where certification is not required
- Where corrosion is limited and visible
- Shorter-term or pragmatic maintenance strategies
Key Consideration
The critical factor in selecting a coating system is whether the roof remains structurally sound, and whether the level of assurance provided by the system aligns with the requirements of the project.
Next Steps
If you are unsure which system is appropriate, correct assessment of the roof condition is essential before specification or application.
