Mix base and hardener evenly per specified ratio, stand 10~20 minutes for reaction before use. 2. Thoroughly remove moisture, grease, sludge, dust, rust and corrosive contaminants from substrate surfaces. 3. Fresh cement walls contain abundant free moisture and alkaline substances which degrade film performance and adhesion. Allow full drying until moisture content drops below 12% before construction. 4. Avoid construction during rain or when relative humidity exceeds 85%RH. 5. Adequate ventilation is required when working inside tanks. 6. If recoating interval exceeds the specified maximum time, roughen the old coating surface to enhance interlayer adhesion. 7. Coal tar bleed-through will occur if topcoated; this product cannot be overcoated with colored finish coats. ## Note All data provided in this product datasheet are derived from internal laboratory test data for construction design reference only.
