Mix base and hardener evenly per specified ratio, let stand 10~20 minutes for reaction before use. 2. Fully remove moisture, grease, sludge, rust and corrosive salts from substrate surfaces to guarantee protective performance. 3. Avoid construction when temperature below 10°C, raining or relative humidity exceeds 85%RH; fully dry damp surfaces before coating. 4. Clean all tools thoroughly after use. 5. Provide adequate ventilation during tank interior construction. ## Note All datasheet data are internal laboratory test results for construction reference only.
