How to waterproof a new 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.

Bathroom waterproofing, it is recommended to use mortar waterproofing agent to do, not only with the base surface paste firm and puncture resistance, high strength, environmental protection and non-toxic construction is simple, waterproof years can also be the same life as the building, is now the preferred material for home decoration waterproofing! It is necessary to pay attention to the construction according to the product construction instructions, so as to ensure a good waterproof effect.

1.Clean the construction site and sprinkle water to make it fully moist but there should be no stagnant water.

2.Wall: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 10 mm for the wall, not less than 20 mm for the ground, and not less than 1800 mm for height.

1) Mix "Lauyer mortar waterproofing agent" with cement at 1:3 to form a waterproof mortar, and paint it once or twice on the base surface, with a total thickness of 2 mm.

2) After 20 minutes, after the waterproof mortar is dry, stir it into a waterproof mortar with "Laoyal" and cement and sand according to 1:2:6, and wipe it on the surface of the waterproof plain ash with a thickness of 8 mm.

After the waterproof mortar layer is solidified, it is cured by sprinkling water.

The steps of waterproofing the bathroom are roughly divided into four parts.

1. Grassroots treatment. First of all, we must carry out ground treatment to ensure that the ground is clean, there is no debris pollution, the surface of the base is solid, there is no peeling and other phenomena, we also need to carry out ground leveling to ensure that the ground is flat, and there are no large defects and traces.

2. Brush waterproof coating. Before we paint the paint, we should ensure that the bathroom is clean and dry. The waterproof coating should be fully brushed and firmly combined with the base layer, so that there will be no bubbles, falling off and other problems.

When we paint, we should paint from the bottom up, first the wall and then the ground. Generally speaking, the waterproofing of the bathroom should be 180 cm, and the waterproofing of the non-shower wall should not be less than 35 cm. It is recommended to do 180 cm.

Brush paint not only pay attention to the height, but also pay attention to the thickness of the brush, the state stipulates that the waterproof paint should be coated to a millimeter thickness. The waterproof paint is brushed twice, and the second coat is to wait for the first coat to dry before you can start brushing.

3. Lay a protective layer. We also need to lay another layer of protective layer on the waterproof layer, and the protective layer should be completely covered with the waterproof layer, and it should be firmly combined with it, and there can be no cracks, bubbles, falling off and other problems.

4. Closed water test. Before doing the closed water test, all the sewer in the bathroom should be blocked, and a simple 25 cm high threshold should be made at the door of the bathroom, the bathroom should be sealed, and then 20 cm high water should be poured into the bathroom. After 24 hours, the water in the bathroom does not leak, and the toilet waterproofing project can be considered qualified.

Hello, all the places that need to be excavated are done in advance, repaired with cement and started to do waterproofing, and then lay pipelines. The same is done for kitchen waterproofing.

The new bathroom can be waterproofed with JS composite waterproof coating for waterproof construction, painted 2-3 times, the thickness is, and the base surface should be guaranteed to be free of hollows and bubbles during the painting process.

There is another way, you can use nano silicon waterproofing agent for spraying, nano silicon waterproofing agent can penetrate 1mm deep, up to 5-10 years of waterproof effect, the effect is very good.

Do waterproofing first, in plastering. Then scrape putty, after doing water and electricity, at least 24 hours of ground closed water test before laying floor tiles. Because there are few leaks in the kitchen, it is generally not waterproof in a large area, and the sewer pipe and floor drain can be waterproofed.

The whole process from the beginning to the end of the roof waterproofing.

The surface of the concrete base is cleaned, the cement mortar screed, the air insulation layer of the full membrane, the insulation layer of the extruded polystyrene board, the cement mortar screed, the polymer SBS waterproof membrane two, the dry paving thick geotextile isolation layer, and the C20 fine stone concrete surface layer.
