How to standardize the waterproofing of the bathroom

1. Bathroom waterproof construction steps.

Step 1: You can use a slightly coarser cement to base the foundation first, and then brush the waterproof paint after the cement is dry. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes.

Step 2: Mix the powder and liquid material evenly, and brush the bubbles if there are bubbles when brushing the paint.

Step 3: When brushing the paint, brush it from the same direction, wait 1-2 hours, and then brush the second coat. When brushing the second layer, the direction of the brush should be opposite to that of the first layer, so that the best coverage can be achieved.

Step 4: You can brush it several times, which can increase the density and fill the gaps. Some people think that the more layers of waterproof paint the better, or even brush six or seven layers, but in fact, this is not good, the paint is too thick and easy to crack.

Step 5: Wait for one day before taking a waterproof test.

Step 6: When doing the waterproof test, you should first fight with your downstairs neighbor.

Say hello, then plug the drain, fill the ground with water, and wait an hour to ask your downstairs neighbor if there is a leak. If there is a water leak, the waterproofing layer should be rebuilt. If the waterproof test is qualified, it can be tiled.

2. Precautions for waterproofing in the bathroom.

1. In order to ensure that the bathroom floor is flat, it must be leveled with cement mortar, and then waterproof, so as to avoid leakage caused by uneven thickness of waterproof coating.

2. After leveling, when carrying out the construction of the waterproof layer, it is necessary to pay attention to fire prevention and waterproofing.

3. When doing waterproof construction, the floor drain, pipeline, and wall hole should be carefully inspected, and the root of the pipeline must be caulked according to the requirements during construction. 4. The waterproof treatment of the wall should also be noted, if the wall and the bathtub are adjacent, then the waterproof treatment height should be higher than the upper edge of the bathtub, and the shower should reach a height of 180cm.

5. Before doing waterproofing, pay attention to the correct position of the floor drain elevation.

6. To ensure that the sewer is smooth, the sewer pipes in the bathroom, including floor drains and toilet sewer pipes, must be kept unobstructed.

If you want to do a good job in the waterproofing of the bathroom, the first thing is to choose the right waterproof material, and secondly, you need to cooperate with the standard construction, so that the waterproof effect of the bathroom will be guaranteed.

The bathroom itself is a relatively stable part of the house structure, and at the same time, according to the usual water leakage summary, more than 80% of the water leakage in the bathroom is concentrated in the yin and yang corners, pipes, sanitary ware, floor drains and other places, so these places are key areas when doing waterproofing. The use of kitchen and bathroom waterproof slurry for waterproofing is to first use quick-setting repair mortar to repair and strengthen these places, and then use the prepared permanent waterproof slurry to do waterproofing as a whole, so that both the part and the whole are taken into account, and the waterproof effect will of course be better.

As for standard construction, it is necessary to pay attention to the height, thickness, interval time, and later sprinkling and curing. In the bathroom, the ground needs to be done all, the wall should be at least meters, it is recommended to do the full height, if it is a lightweight wall, then it must be done full height, the thickness is generally, the interval time is not sticky to the touch.

It is a very important process to do toilet waterproofing, and waterproof construction should be coated with waterproof waterproof The performance of waterproof materials should meet the provisions of the current national standards, and there should be a product qualification certificate; The surface of the base should be smooth, and there should be no defects such as hollowing, sanding, cracking, etc., and the moisture content of the base should meet the construction requirements of waterproof materials; THE WATERPROOF LAYER SHOULD EXTEND FROM THE GROUND TO THE WALL, 250MM HIGHER THAN THE GROUND, AND THE HEIGHT OF THE WATERPROOF LAYER ON THE WALL OF THE BATHROOM NEAR THE SHOWER HEAD SHALL NOT BE LESS THAN 1800MM; THE WATERPROOF LAYER OF THE COATING FILM IS EVENLY BRUSHED, THE GENERAL THICKNESS SHALL NOT BE LESS THAN 1 5MM, THE WATERPROOF SURFACE OF THE COATING FILM IS NOT BLISTERING, NOT FLOWING, SMOOTH AND CONVEX, AND THE JOINTS OF PIPE FITTINGS, SANITARY WARE FEET, FLOOR DRAINS, AND DRAINAGE OUTLETS ARE TIGHT, AND THE END IS SMOOTH AND DOES NOT LEAK After the waterproof project is completed, it is necessary to do a 24-hour water storage experiment.

In addition, because asphalt is used for indoor waterproofing, it is easy to decompose toxic substances and cause harm to the human body, and now the state has clearly stipulated that asphalt cannot be used as a waterproof material.

The shower part is 1 meter 8, and the other parts are 1 meter, and after 24 hours of blocking the door and releasing water to do the closed water experiment, go to the top of the downstairs bathroom to check whether there is leakage.
