1、应先对下层进行处理。去除原有的防水材料,把浮土水泥清理干净,要求外观平整干燥。

1, should be the primary treatment. The removal of the original decoration materials, the cement surface clean, smooth surface drying requirements.

2、铺贴屋顶防水涂料。在做屋顶防水处理的下层上刷一层屋顶防水涂料,铺一层防水聚酯布,然后再重复涂刷一次防水涂料,完全干燥后再整天涂刷一遍屋顶防水涂料,屋顶防水处理才算做完。屋顶防水涂料应刷均匀,防水布与屋顶防水层封闭精密,不能有漏刷,起鼓和脱落的征象,否则会影响屋顶防水结果。

2, paving waterproof coating. On the basis of a layer of waterproof coating, a layer of non-woven fabric, and then repeat the brush once, and finally in the second layer of non-woven fabric on a waterproof coating, waterproof treatment is done. Waterproof paint should be uniform brush, non-woven fabric and waterproof layer closed tight, can not have the leakage brush, drum and off phenomenon, otherwise it will affect the waterproof effect.

若选用聚氨酯做屋顶防水涂料,一般不用加防水布,只要反复涂刷2-3遍就可以了。由于聚氨酯涂料自己可以形成弹性的保护膜,具有肯定的耐拉力性能。为了进步屋顶防水结果,可以铺贴一层聚酯布,但费用会有所增长。

If the use of polyurethane waterproofing paint, generally do not add non-woven, as long as the repeated brushing 2-3 times on it. Because the polyurethane coating itself can form a flexible protective film, has a certain tensile properties. In order to improve the waterproof effect, can be coated with a layer of non-woven fabric, but the cost will increase.

3、做“蔽水”实验,蔽水试验是检验室内屋顶防水质量的紧张检测手段。在屋顶防水工程做完后,封好门口及下水口,在室内蓄满水达到肯定液面高度,24小时内液面若无显明降落,即为合格。

3, do 'water' experiment, water test is an important means to test the quality of indoor waterproof detection. After the completion of the waterproof project, sealed the door and the mouth, filled with water in the room to reach a certain height of the liquid level, within 24 hours without a significant decline in the surface, that is qualified.

蔽水试验完成后,在屋顶防水涂料层上再做一层水泥砂浆保护层,细致不要破环已做好的屋顶防水涂料层。等水泥砂浆保护层干透后,就可以在上面铺贴墙地砖或喷刷涂料,进行正常的装饰装修了。

After the completion of the water test, make a layer of cement mortar protection layer on the waterproof coating layer. After the cement mortar protective layer is dry, it can be used for paving the floor tile or spray paint on the top, and it can be used for normal decoration.
