5. Substrate Preparation

1. The substrate shall be pre-treated by processes such as grinding, sandblasting, and shot blasting to ensure the surface is clean and smooth.
2. Concrete substrate: The loose part on the surface shall be removed to expose the solid substrate; the substrate shall be free of moisture and visible water. For surface holes, special repair putty shall be used for plugging, and then the matching primer shall be applied.
3. Steel substrate: It shall be treated to Sa2.5 grade standard by sandblasting and shot blasting. After dust removal, the corresponding primer shall be applied.
4. For other types of substrates, please consult the Technology Department of Wanhua Energy-Saving Company for professional guidance before construction.

6. Construction Conditions

1. Temperature: The ambient temperature shall be controlled at 5-35℃, and the substrate temperature shall be more than 3℃ higher than the air dew point temperature.
2. Humidity: The relative ambient humidity shall be ≤80% RH, and the moisture content of the concrete base surface shall be less than 6%.
3. Ventilation: Strong wind shall be avoided at the construction site to prevent dust from entering and affecting the compactness of the coating, and good ventilation of the construction environment shall be ensured.
