Mix base and hardener evenly as specified, stand 10~20 minutes for reaction before use. 2. Fully remove moisture, grease, sludge, dust, rust and corrosive salts from substrate surfaces. 3. Avoid construction when temperature below 10°C or relative humidity exceeds 85%RH; fully dry damp surfaces before coating. 4. Clean all coating tools immediately after use. 5. Maintain adequate ventilation during confined tank interior construction. 6. Roughen the aged coating surface if recoating interval exceeds the limit to improve interlayer adhesion. ## Note All datasheet data are internal laboratory test results for construction reference only.
