What problems should be paid attention to when making a waterproof layer in the bathroom?

1. Be sure to clean the base layer ready to be waterproof, and try to keep the surface dry.

2. Carry out construction according to the process requirements of waterproof materials. It should be noted here that the leakage parts of the bathroom are mainly at the root of the upper and lower water pipes and the foot of the wall, so when these places are waterproofed, it must be "full", and its practical fingers can be hooked. Also note that waterproofing needs to be done from the foot of the wall upwards not less than 25 cm as well.

3. If a certain wall of the bathroom is a light wall, it is necessary to waterproof the whole wall.

4. After the waterproof material is dry, it is necessary to carry out a 24-hour closed water test to observe whether there is any water leakage. After doing this, there will generally be no water leakage.

1. Waterproof coatings should be selected from regular manufacturers.

2. The ground should be cleaned before waterproof construction, and there should be no sand and other sundries.

3. The number of layers of waterproof coating should be at least 2 layers.

4. The waterproof height of the bathroom should be higher than the meter.

5. The waterproof coating should be dried in the shade.

6. After completion, it is necessary to avoid water for at least 24 hours.

First of all, the waterproof material should be good, and secondly, the workers should operate properly, and pay attention to the waterproof coating to be higher.

The height of the waterproof, the waterproof layer has been coated several times, and the water has been tested after it has been done.

Two more coats of waterproof paint near the floor drain pipe should be applied.

The authenticity of waterproof products.

First, to level the layer: first use cement mortar to flatten the ground, and then do waterproof treatment. This avoids leakage caused by uneven thickness of the waterproofing coating or puncture of the waterproofing membrane;

Second, it is necessary to do a good job in key parts: the joints between the wall and the ground, as well as the joints between the water and water pipes and the ground, are the most likely places to cause problems. Therefore, these parts must be paid special attention, and the treatment must be meticulous, without the slightest sloppiness;

3. The wall should also be waterproofed: in order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproof about 30cm high to prevent water from penetrating the wall. The wall adjacent to the bathtub should also be waterproofed at a higher height than the top edge of the bathtub.

Fourth, do a waterproof test: after the waterproof construction is completed, all the sewers of the bathroom should be blocked, and a "low wall" should be built at the door of the bathroom for water injection test, and the water injection height should be about 20cm. After 24 hours, if there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good.

On the contrary, it is necessary to find out the leakage point and carry out repairs.

To do waterproofing in the bathroom, you need to pay attention to the following things:

1.The first thing to pay attention to when doing waterproofing in the bathroom is the choice of waterproof materials, and it is recommended that you can directly use the waterproof slurry in the kitchen and bathroom, which is specially developed for the yin and yang angles that are easy to seep into the kitchen and bathroom, wear pipes, sanitary ware, floor drain peripherals, etc., so the special materials are dedicated, the pertinence is stronger, and the waterproof effect is of course better.

2.The construction of waterproofing should be carried out in accordance with the requirements of the manual, the proportion of waterproof materials, the standard thickness and height of construction, etc., so as to ensure a good waterproof effect.

3.After doing a good job of waterproofing, it is necessary to do a good job of sprinkling and maintenance in the later stage, and places with direct sunlight need to be covered and covered.

4.The base surface before waterproofing must be cleaned, there can be no oil and dust, etc., and it must be sprinkled with water to moisten, but there must be no stagnant water.

5.After the waterproofing is completed, remember to do a 48-72 hour closed water test to check whether there are any leaks in the waterproof construction and whether the waterproof function is normal.

There are generally three materials for waterproofing in the bathroom, one is composite cement-based waterproofing, one is asphalt membrane or asphalt paste, and the other is polypropylene tarpaulin. No matter which one it is, first of all, the base layer should be cleaned before the construction of the waterproof layer of the bathroom, and the base layer should be kept clean and dry, without hollowing out the dust, etc., and secondly, the construction of the waterproof layer should be carried out. The cement-based waterproof layer is brushed with a brush, and the back-and-forth regression coating does not leave dead ends, generally two to three times.

After applying the desert layer and taking a dry bath, the interval is used. After completion, the waterproof layer is not hollow and does not peel. After drying, the water should be closed for 48 hours, and no seepage or leakage will be qualified.

Finally, it is necessary to make a mortar waterproof protective layer. When making a protective layer, remember not to damage the waterproof layer. The other two waterproofing layers are much the same.
