四、施工注意事项 Construction precautions
☆聚脲防水涂料喷涂施工前的注意事项：
1、聚脲施工前应保证基层温度高于露点温度3℃，施工过程中应保持连续搅拌。
2、若检验时发现聚脲涂层有鼓泡、漏喷等缺陷，则需要立即进行修补。
3、如缺陷部位发现离喷涂时间较短(≤6h)，可对缺陷涂层表面进行打磨，清理后直接进行二次喷涂聚脲。
4、如果缺陷部位发现离喷涂时间较长(>6h)，则应对缺陷涂层表面(向外扩展5-10cm范围)打磨清理后，施作专门的处理剂，然后采用专用修补设备喷涂聚脲防水涂料并修补、刮平，使整个涂层连续、致密、均匀。
☆Matters needing attention before spraying polyurea waterproof coating:
1. Before polyurea construction, the temperature of base course should be 3 ℃ higher than dew point temperature, and continuous mixing should be maintained during construction.
2. If it is found that the polyurea coating has defects such as bubbling and leakage during inspection, it needs to be repaired immediately.
3. If it is found that the time from spraying is short (≤ 6h), the surface of the defective coating can be polished, and the secondary spraying of polyurea can be carried out directly after cleaning.
4. If the defective part is found to have a long time from spraying (> 6h), the surface of the defective coating (extending 5-10cm outwards) shall be polished and cleaned, then special treatment agent shall be applied, and then polyurea waterproof coating shall be sprayed with special repair equipment, repaired and scraped to make the whole coating continuous, dense and uniform.
☆聚脲防水涂料喷涂施工时注意事项:
1、在进行喷涂聚脲施工时，应根据需用材料设置合适的温度、压力等设备参数，保持压力平衡，压力偏差过大会导致涂层理化性能下降、起泡、不固化等问题。
2、按照施工环境选择底涂:湿度高、潮湿基材选择潮湿界面专用底涂。
3、低温施工时选择低温固化底涂。
4、雨天不得施工;四级以上风力不宜施工。
5、施工过程中操作人员需穿工作服，佩戴目镜、手套、防毒面具等劳保用品，并保证施工环境通风良好。
6、施工现场应安全用电，杜绝火源并配备好相应的消防器材。
Matters needing attention during spraying construction of polyurea waterproof coating:
1. During the spray polyurea construction, appropriate equipment parameters such as temperature and pressure should be set according to the required materials to maintain pressure balance. Excessive pressure deviation will lead to the degradation of physical and chemical properties of the coating, foaming, non curing and other problems.
2. Select the primer according to the construction environment: select the special primer for wet interface for high humidity and wet substrate.
3. Low temperature curing primer is selected for low temperature construction.
4. No construction is allowed in rainy days; It is not suitable for construction when the wind force is above grade 4.
5. In the process of construction, operators should wear work clothes, eyeglasses, gloves, gas masks and other labor protection appliances, and ensure that the construction environment is well ventilated.
6. Construction site should be safe use of electricity, put an end to fire, and equipped with appropriate fire equipment.
