1. Select waterproof material specific issues specific treatment, choose the waterproof material to use the environment, choose the most suitable, and not waterproof to do a good job on everything, and hot and cold water, detergent erosion will have an impact on the water. 
Therefore, when these reasons lead to waterproofing, the requirements for the performance indicators of the waterproofing agent are very high. At the time of purchase, products with excellent quality and good reputation should be selected by the regular manufacturers. And because the performance of different waterproof materials are different, so it is necessary to strictly follow the requirements of the product specification construction, unclear place, not too much trouble, make a phone call to consult the manufacturers. 
2. Before the wall and floor are leveled and waterproofed, be sure to level the wall surface first. If the leveling effect of the wall surface is not good, it may cause cracking and leakage due to uneven thickness of the waterproof coating. 
Make sure that waterproofing is done before paving the floor slabs; make sure that there is a slope (typically about 1%) on the surface of the bricks, and that the slope is facing the floor drain; you must make a water-sealing experiment for at least 24 hours after the paving. 
3. Detail Waterproofing It must be noted that the seams on the wall and the ground, the corners of the yin and yang, the water pipes, the floor drains, and the perimeters of the sanitary ware and the slots where the hydropower pipes are laid are key waterproof parts. 
The nozzles, inside corners and lintels are pre-applied and the width is about 200mm. If it is possible to add a layer of glass fiber mesh on top, the addition of grid cloth can greatly improve the ability of the coating to resist deformation of the base surface. 
In the buried water pipe in the wall, the groove larger than the pipe diameter is to be cut, the plaster is smooth and smooth, and then the waterproof coating is applied finely. 4. When the waterproof brush is applied for the first time in the construction of the brush, it must be ensured that the site is clean and dry. The cross brushing method is used. The first is far and near, and the first is difficult. The brush is prevented from leaking, and it is firmly bonded to the grass roots. No cracks are found. Bubbles, no shedding. The brushing height is the same and the thickness must meet the product requirements. 
When brushing the second time waterproof coating, it should be perpendicular to the first pass. Note that there is a certain time interval between the first and second pass of the waterproof coating. After the first pass of the coating, the second pass can be performed. The specific time may depend on the use of the coating. The interval is too short and the effect of waterproofing will be affected. 
5. Make a protective layer In order to prevent the subsequent construction from damaging the waterproof layer, a protective layer must be applied on the surface of the waterproof coating. The protective layer must completely cover the waterproof layer without any omission. It has a strong bond with the grass roots, no cracks, no bubbles, and no shedding. 
6. Closed water test Closed water test is the most critical step and must not be ignored. Some construction teams are irresponsible for not closing the water test for the duration of the project. 
After the water-proof paint dries out, conduct a water-removal test and block the roots, floor drains, etc., and store water. The water at the highest point on the ground must not be lower than 2 cm. Store at least 24 hours and check whether the top of the next floor is wet or not. Pipeline mouth, chimney mouth and other leaks. After observing no leakage, it is considered as qualified. 
Waterproof construction, these six steps, one step will not work, just keep in mind these six steps, I believe that you encounter waterproof problems, do not need to wait for professionals, you can first deal with it. New skills quickly get it!
