Mix base and hardener fully per specified ratio, apply within 60 minutes after mixing. 2. Fully remove grease, sludge, dust, rust and corrosive salts from substrate surfaces. 3. Surface preparation standard: ISO Sa 2 1/2 or SSPC-SP10, surface roughness ≥30μm. 4. Wear protective gloves; small residual paint left in cans shall be diluted with thinner and sealed in small containers to avoid skin contact hazards. 5. Full ventilation required during confined tank interior construction. 6. Roughen aged coating surface if recoating interval exceeds the limit to improve interlayer adhesion. ## Note All datasheet data are factory laboratory test results for construction reference only.
