In general, the bathroom shower area is 180cm high in waterproof, non-shower walls and kitchen, balcony wall in principle, waterproof paint can not be less than 30cm. In addition, for the bathroom light walls and self-built light walls, it is recommended that the waterproof height be the top. In terms of thickness, the waterproof coating must be brushed to the 1.5mm thickness of the national acceptance specification.

Second, the wall pouring test

Drenching test is a method specially used to test whether the waterproof construction of the wall is qualified. The general practice is to use a water pipe to spray the water from the top to the bottom for 3 to 4 minutes, and then check the other side of the wall to see if there is no penetration.

Third, the bathroom closed water test

Compared to kitchens and balconies, bathrooms are often large water users, and there is often accumulated water on the ground. Therefore, the acceptance of bathroom waterproofing should be more stringent, and generally it should be tested through closed water test.

The closed water test must be done after the waterproof coating dries out, usually after a day or two after brushing the waterproof coating. Before closing the water, first put the prepared sand into a plastic bag, tightly plug the floor drain, prevent the stored water from running off, and then block the entrance door with water that may be full.

2, the height of closed water test

The height of the closed water must be soaked in the entire surface of the water-coating test. It is usually sufficient to put 10cm on it. If it is feared that the water will evaporate within the next 48 hours, it is generally 20cm.

3, the time of closed water test

The closed water test time is at least 24 hours in summer and at least 48 hours in winter. During this period of time, it is observed whether there is a significant drop in water level, especially if there is any leakage in the roof of the house downstairs to check whether the waterproof construction is qualified. If there is a leak, the waterproof is not qualified, then it needs to be re-waterproof. After the second time of waterproofing, it needs to be closed.

Fourth, understand the law and safeguard the rights and interests

General housing waterproofing is carried out by the decoration company. According to Article 32 of the “House Interior Decoration Management Regulations”, under the normal conditions of use, the minimum warranty period for residential interior decoration works is two years, and there is a kitchen with waterproof requirements. Bathrooms and external walls and prevent leakage for five years. Therefore, if the house leaks within 5 years, you can find a decoration company to ask for responsibility.

Part2, bathroom waterproof key water-closed test is the key

The bathroom is a key area of ​​home waterproofing, because the bathroom wall is often flooded with water, and the ground is often filled with water. Compared with other spaces, bathroom waterproofing requirements are more stringent and must be ensured. Therefore, after the waterproofing of the bathroom is completed, water-rejection tests must be performed, and other waterproof spaces such as kitchens and balconies are generally not required.

First, the choice of bathroom waterproof coating

There are many kinds of waterproof coatings on the market. When choosing a waterproof coating, it is necessary to choose according to the waterproof requirements of different parts.

Third, the key parts of the bathroom waterproof treatment

Floor drain parts, small water pipes and floor joints, and toilet pipes are often the places where the bathroom leaks most easily. In the construction, it is necessary to focus on these parts. In general, other parts are brushed twice. Here, it needs to be brushed many times; in addition, more leakage occurs below the passstone. During construction, it is necessary to make a zone in advance under the gateway stone. The waterproof must be rolled over the zone so as to form a basin and form the function of water storage and water retention.

Fourth, bathroom closed water test

The closed water test in the bathroom must be done after the waterproof coating dries out. Before the water is shut off, firstly the ground drain and other drainage points should be blocked, and the door sill should be blocked to prevent the water from flowing out of these parts after the storage. After blocking, then release water, generally put 10cm, and then test at least 24 hours, at least 48 hours in winter, during this period of time to observe whether there is a significant decline in the water, in particular, check whether there is leakage at the top of the bathroom downstairs.
