Professional Application Process
Systematic methodology for optimal results in structural repair applications
Surface Preparation
Mechanical cleaning and routing of cracks wider than 5mm to ensure optimal epoxy penetration and adhesion.
Port Installation
Strategic placement of injection ports at 150-300mm intervals along crack path for controlled epoxy distribution.
Material Preparation
Precise 4:1 ratio mixing with low-speed equipment to maintain viscosity and extend 60-80 minute pot life.
Pressure Injection
Controlled injection from lowest point upward until epoxy emerges from adjacent port, ensuring complete filling.
Curing & Finishing
7-day cure period at 23°C followed by port removal and surface finishing for professional appearance.
Technical Application Guidelines
Professional specifications for optimal performance and compliance
Application Specifications
Surface Preparation: Substrate must be clean, sound, and free of contaminants. Mechanical preparation required for optimal adhesion.
Temperature Range: Apply between 8°C – 30°C substrate temperature. Material temperature should be 15°C – 25°C.
Mixing Procedure: Precisely measure components 4:1 by weight. Mix at low speed for 3 minutes until homogeneous.
Application Method: Use professional injection pumps for controlled pressure application. Inject from bottom port upward.
Curing Conditions: 7-day cure at 23°C. Protect from moisture and temperature extremes during curing period.
Coverage Rates: 20 sqft/litre for new substrates, 30 sqft/litre for existing surfaces (varies with crack width and porosity).
Safety & Compliance
Personal Protection: Wear appropriate PPE including gloves, safety glasses, and protective clothing during application.
Ventilation: Ensure adequate ventilation in enclosed spaces during application and initial curing period.
Fire Safety: Material is flammable before curing. Keep away from ignition sources and observe fire safety protocols.
Equipment Cleaning: Clean equipment immediately after use with xylene or approved epoxy solvent.
Environmental Conditions: Avoid application during rain or high humidity (>85% RH) to prevent moisture contamination.
Storage: Store in original containers at 5°C – 25°C. Keep away from direct sunlight and moisture.
