Mix base and hardener evenly per specified ratio, let stand 10~20 mins for reaction before diluting with thinner. 2. Fully remove moisture, grease, sludge, dust and other contaminants from substrate surfaces prior to construction. 3. Fresh cement walls contain abundant free moisture and alkaline substances which degrade film performance and adhesion. Allow 2~3 weeks full drying until moisture content drops below 12% before coating. 4. Construction Conditions: Ambient relative humidity below 85%RH, temperature ≥10°C. ## Note All data provided in this product datasheet are derived from internal laboratory test data for construction design reference only.
