Stir thoroughly before use. Dilute with tap water if the paint is too thick; do not exceed the specified dilution ratio. 2. Fully remove grease, dust and other contaminants from substrate surfaces before construction. 3. Use Rainbow water-based colorants for tinting. 4. Fresh cement walls contain excessive moisture and free alkaline substances which will degrade film performance and adhesion. Allow 2~3 weeks for full drying until moisture content drops below 12% prior to coating. 5. Construction Conditions: Ambient relative humidity below 85%RH, temperature ≥10°C. ## Note All data provided in this product datasheet are derived from internal laboratory tests for construction design reference only.
