Add hardener into base component and stir evenly before use. 2. Avoid construction when temperature below 10°C or relative humidity over 85%RH; fully dry damp substrates before coating. 3. Clean all tools thoroughly after use. 4. Apply topcoat within the recoating window to avoid surface contamination which reduces adhesion durability. 5. Not suitable for internal lining of storage tanks. ## Note All datasheet data are internal laboratory test results for construction reference only.
