Frequently Asked Questions

Belzona is a high-performance polymeric repair and protection system designed to rebuild, protect, and extend the life of industrial assets. It adheres chemically to the substrate—metal, concrete, or composites—creating a durable barrier against corrosion, erosion, and chemical attack.

Belzona is often chosen instead of welding or full replacement because it:

• Requires no hot work
• Installs faster, reducing downtime
• Provides long-term corrosion and chemical resistance
• Avoids distortion or weakening of the substrate 
• Offers a more cost-effective, long-life repair

Surface prep depends on the repair environment and specification. Typical options include:

• Grit blasting (preferred for maximum bond strength) 
• MBX bristle blaster
• Mechanical preparation (for confined or hazardous areas

Proper preparation is essential for long-term performance.

Belzona repairs typically provide 10–20+ years of service life, depending on:

• Operating environment
• Product grade
• Surface preparation
• Correct application procedures

Belzona systems address a wide range of industrial issues, including:

• Leakage and sealing
• Corrosion and pitting
• Shaft and keyway repair
• Pipe wrap and reinforcement
• Flange injection
• Tank lining and containment
• Splash zone protection
• Structural rebuilding

Yes. Belzona offers specialized grades formulated for:

• Application on moist surfaces
• Live leak sealing
• Underwater application and curing

Belzona installations typically include a standard 5-year warranty, provided that:

• Application is performed by trained/authorized personnel
• Work follows the official Belzona Method Statement

Resistance varies by product grade. Belzona publishes:

• Chemical resistance tables
• Temperature rating charts
• Pressure and mechanical strength data

These allow engineers to verify suitability for specific operating conditions.

Cure times depend on temperature and product type. Generally:

• Many grades allow rapid return to service
• Cold-cure and emergency products accelerate turnaround
• Full cure can occur within hours at ambient temperature

Yes. Belzona is used and approved globally by major organizations across:

• Oil & Gas 
• Marine 
• Power generation
• Chemical processing and heavy industry
