Practical Suggestions for Your Team (AOG Mindset)

• Condition components between 18°C and 25°C before mixing
• Mix A1500-M base thoroughly before adding hardener
• Ensure matt and semi-gloss bases are fully homogenised before adding hardener
• Add hardener in two stages for matt and semi-gloss finishes
• Respect the 6-hour pot life after mixing
• Control flash-off times between coats to prevent defects
• Use correct thinner ratio to achieve approved spray viscosity
• Maintain clean, dry, oil-free compressed air during application
