## Construction Precautions ⚠️
1. Stir thoroughly before use. If paint is too thick, dilute with tap water without exceeding the specified dosage.
2. Fresh cement walls contain abundant free moisture and alkaline substances, which will degrade film performance and adhesion. Allow 2~3 weeks for full drying until moisture content drops below 12% before construction.
3. Completely remove grease, dust and other contaminants from substrate surfaces prior to application.
4. Construction Conditions: Ambient relative humidity below 85%RH, temperature above 10°C.
