What is the thickness of the waterproof layer in the bathroom?

The height standard of the waterproof layer of the bathroom should be determined according to the different positions, first of all, the waterproof layer of the wall is generally 30 cm upwards from the corner of the wall, the height of the bathing place is generally 180 cm, the height of the basin is 100 cm, the waterproof layer and the ground waterproof are required to do 2 times, do not leave the construction joint in the corner of the wall when waterproofing, the ground waterproof layer should be painted out of the bathroom door 30 cm high, the waterproof floor waterproof layer should be 20 cm higher than the ground.

According to the standard, the waterproof thickness of the toilet is generally not less than; The amount of waterproof material is not less than 2 kg of waterproof coating per square, only in this way can the waterproof effect be guaranteed;

If the waterproof layer is lower than this thickness, or the amount of waterproof paint is small, it must be a worker cutting corners.

The thickness of the waterproof layer in the bathroom is very related to the type of waterproof material you use, if you are using kitchen and bathroom waterproof slurry, K11 waterproof slurry, JS polymer cement-based waterproof coating, etc., then it is generally brushed 2-3 times, and the thickness is kept between.

But if you are using mortar waterproofing agent, then the thickness and waterproof effect are closely related, the ground is generally about 2cm, and the wall is generally about 1cm, so as to ensure the waterproof effect.

The bathroom is waterproof, the standard requirement is that the ground needs to be done, the wall should be at least meter, it is recommended to do the full height, if it is a lightweight wall, then it must be done full height. The waterproof height of the wall is generally 30CM; For non-load-bearing walls, the basic waterproof height should be at least 180CM. Consideration is given to the safety of waterproofing in the toilet and bath and the overall waterproofing effect.

Generally, the shower or sprinkler head is installed at a height of about one meter, if the waterproofing is low, the long-term spraying will cause water to soak the wall, so that the wall mildew, wall decorative layer paint or brick peeling off and other problems, so that the waterproof effect can not be achieved. In principle, non-shower walls can be made to meters, but in order to strengthen the waterproof effect, we all uniformly achieve meter height, and the cost does not increase much. In addition, for the light wall of the toilet and bathroom renovation and the self-built light wall, it is recommended that the waterproof height should be at the top.

The bathroom shower area should be 180cm high or to the top; There is a bathtub on the place to turn the brush 30 higher than the bathtub; Others generally have to be 30cm high.

Toilet waterproof height:

1. The height of the waterproof layer in the wall, column and other parts (above the finished surface of the indoor ground) should not be less than 100mm;

2. Install the wall with hose shower head and the wall on both sides from 1800mm above the ground;

3. The wall surface of the shower head installed with a dark pipe (no hose) and the walls on both sides of the wall from above the ground should not be lower than the height of the shower head, and should not be less than 1800mm;

4. The wall in contact with the bathtub is 300mm above the top surface of the bathtub from the ground;

5. The wall in contact with the washbasin should be 300mm from the ground to the top of the washbasin;

6. The urinal is 1800mm above the ground;

7. The pipe (including the casing) through the floor slab is 100mm above the root of the pipe. It is provided by Master Bang Maintenance.

The national standard stipulated by the National Construction Committee for the bathroom waterproof height is meters, the house has been built when the building waterproof work, the waterproof layer extends from the ground to the wall, 250MM higher than the ground. However, there is basically no waterproofing of the wall.

IF THE BATHROOM IS A SHOWER, THEN THE HEIGHT OF THE WATERPROOF LAYER ON THE WALL OF THE SHOWER HEAD IN THE CONVENTIONAL BATHROOM SHALL NOT BE LESS THAN 1800MM, AND THE GENERAL THICKNESS SHALL NOT BE LESS THAN 1 5MM, AND THE WATERPROOF PROJECT MUST BE COMPLETED FOR 24 HOURS WATER STORAGE EXPERIMENT, AND OTHER WALLS CAN BE DONE BY ONE METER. If the bathroom is a bathtub, the waterproof height of the wall adjacent to the bathtub is 30cm higher than the bathtub.

However, it should be noted that the waterproof water pipe joints on the ground, the leveling of the waterproof ground, the waterproof layer of several positions such as shower switches, toilets, etc., cannot affect the height of the tiles.

Waterproof layer: A material layer designed to prevent rainwater from entering the roof, groundwater from infiltrating into walls, basements and underground structures, and indoor water from infiltrating into floors and walls.

The National Code for the Construction of Residential Decoration and Decoration Engineering clearly points out that the waterproof layer should extend from the ground to the wall, 100 mm above the ground; The waterproofing layer of the bathroom wall must not be less than 1800 mm. Closed water test must be done:

Block all the sewers in the bathroom, and build a 250 mm high "sill" at the door, pour in 200 mm high water, and after 24 to 72 hours, confirm that there is no leakage and then paste the tiles.

The thickness of the bathroom waterproof layer is very related to the type of waterproof material you use, if you use kitchen and bathroom waterproof slurry, K11 waterproof slurry, JS polymer cement-based waterproof coating, etc., then it is generally brushed 2-3 times, and the thickness is kept between.

But if you are using mortar waterproofing agent, then the thickness and waterproof effect are closely related, the ground is generally about 2CM, and the wall is generally about 1CM, so as to ensure the waterproof effect.

If polypropylene is used for construction, 400 grams of polypropylene are generally used.

The national standard for coating construction is thick
