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