The requirements of the bathroom waterproof standard are that the ground needs to be done all, and the wall is at least full high, and if it is a lightweight wall, then it must be done full height. As for the material, it is recommended to use kitchen and bathroom waterproof slurry.

1. Bathroom waterproof construction steps.

Step 1: You can use slightly coarser cement as a primer first, and wait for the cement to dry before brushing the waterproof coating. 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.

1: Do a good job in hydropower infrastructure projects.

From a safety point of view, it is better to go up the bathroom water pipes and wires than to go down. However, many "guerrillas" are greedy for labor-saving, and water and electricity go to the ground, and even dig grooves and round holes in the bathroom.

2: Clean the base and walls.

The house is decorated with waterproof, involving a balcony, a kitchen, a bathroom, but the focus is on the bathroom. First of all, use a small metal hammer to knock on the wall and ground, if you find a "poof" empty sound, it means that there is a hollow drum inside, and you must knock out all the hollow drum parts. Then carefully clean the four wall base layers and the floor, pull out the nails, clean up the miscellaneous garbage, rinse it with clean water, and then let it dry.

3: Do a good job of rigid waterproofing.

All kinds of sewer pipes in the bathroom can not be changed, try not to change them; In case of change, you must not use cement mortar to fill the pores, and you must plug the leakage king to fill it three times.

4: Do the second level of elastic waterproof coating.

After a long time in the new house, the hard plugging king elastic coating will be cracked alive due to settlement, thus losing the waterproof effect. Therefore, it is necessary to add a second insurance - elastic waterproofing coatings.

1. Try not to damage the original waterproof layer.

In the newly delivered high-rise building, the waterproof layer is usually made in accordance with the relevant standards, but in the process of decoration, some bathroom bathing equipment and a variety of water and water pipelines may be re-planned, and then the original waterproof layer of the building may be damaged. Qinglong Construction recommends that friends who need decoration should try not to damage the original waterproof layer, and if it is damaged, it must be repaired in time to avoid leakage in the future.

2. Re-paving floor tiles should be waterproof on the ground.

If you need to replace the original floor tiles in the bathroom, after chiseling off the original floor tiles, you must first level the ground with cement mortar, and then do waterproof treatment, so as to avoid leakage caused by uneven thickness of the waterproof coating.

3. The wall must be waterproof.

Water will splash on the nearby wall when bathing in the bathroom, and if you don't do waterproofing, the wall will be prone to mildew, so you must do a good job of waterproofing the wall before laying wall tiles. Qinglong construction suggests that the wall should not be less than 30 cm when waterproofing, and if the load-bearing light wall is right, the entire wall should be waterproofed.

4. The grooves of the water pipes in the wall should also be waterproof.

During the construction process, when pipes, floor drains, etc. pass through the floor slab, it is necessary to carefully construct the waterproof layer around the hole. Buried water pipes in the wall, so as to achieve reasonable planning, lay water pipes are all made larger than the diameter of the groove, the groove is plastered smoothly, and then the groove is brushed with polyurethane waterproof coating.
