## Construction Precautions ⚠️
1. Mix base and hardener evenly in specified ratio, let stand for 10~20 minutes induction time before use.
2. Fully remove all surface contaminants including moisture, grease, sludge, dust, rust and corrosive salts from substrates.
3. Avoid construction when temperature below 10°C, raining or ambient relative humidity over 85%RH. Fully dry damp surfaces prior to coating.
4. Clean all coating equipment immediately after use.
5. Ensure sufficient ventilation during construction inside tanks or pits.
6. Sand the coating surface if recoating interval exceeds specified time to improve interlayer adhesion.
