Packaging and Storage:
During transportation and storage, attention should be paid to moisture-proof, so as to avoid caking affecting the use effect, and the storage period is two months.
Construction method:
- 1.Dry spraying with water added to the gun head.
- 2. Wind pressure 5-8 kg/cm³and water pressure 4-5 kg/cm³.
- 3. The distance between the gun head and the surface of the construction body should be 0.8-1m.
- 4. The thickness of primary spraying should not be greater than 30-50 mm.
