Mix base and hardener evenly in specified ratio before use. 2. Thoroughly remove all surface contaminants including moisture, grease, sludge and dust from substrates. 3. Avoid construction on rainy days or when ambient relative humidity exceeds 85%RH. Fully dry damp substrates before application. 4. Clean all coating equipment immediately after use. 5. Ensure sufficient ventilation during construction inside pits or tanks. 6. Sand the coating surface if recoating interval exceeds specified time to improve interlayer adhesion. ## Note Actual coverage varies depending on workpiece size, shape and construction environment.
