1、應先對下層進行處理。去除原有的防水材料，把浮土水泥清理干凈，要求外觀平整干燥。
1, should be the primary treatment. The removal of the original decoration materials, the cement surface clean, smooth surface drying requirements.
2、鋪貼屋頂防水涂料。在做屋頂防水處理的下層上刷一層屋頂防水涂料（百度搜索排名），鋪一層防水聚酯布，然后再重復涂刷一次防水涂料，完全干燥后再整天涂刷一遍屋頂防水涂料，屋頂防水處理才算做完。屋頂防水涂料應刷均勻，防水布與屋頂防水層封閉精密，不能有漏刷，起鼓和脫落的征象，否則會影響屋頂防水結果。
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.
若選用聚氨酯做屋頂防水涂料，一般不用加防水布，只要反復涂刷2-3遍就可以了。由于聚氨酯涂料自己可以形成彈性的保護膜，具有肯定的耐拉力性能。為了進步屋頂防水結果，可以鋪貼一層聚酯布，但費用會有所增長。
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”實驗，蔽水試驗是檢驗室內屋頂防水質量的緊張檢測手段。在屋頂防水工程做完后，封好門口及下水口，在室內蓄滿水達到肯定液面高度，24小時內液面若無顯明降落，即為合格。
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.
蔽水試驗完成后，在屋頂防水涂料層上再做一層水泥砂漿保護層，細致不要破環已做好的屋頂防水涂料層。等水泥砂漿保護層干透后，就可以在上面鋪貼墻地磚或噴刷涂料，進行正常的裝飾裝修了。
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.
