How can I make the bathroom waterproof?

First, we must do the leveling layer. First of all, the ground should be leveled with cement mortar (especially for houses to be renovated), and then waterproofing. This avoids leakage of the waterproofing coating due to uneven thickness.

Second, we must do a good job in key parts. The joints between the wall and the floor, as well as the joints between the water and sewer pipes and the ground, are the most problematic areas. Therefore, these parts must be paid special attention to, and the treatment must be meticulous, without the slightest sloppiness.

Third, the wall should also be waterproof. In order to achieve a better waterproof effect, the wall of the general bathroom should be about 30cm high, and the shower area should be about 30cm high.

Fourth, we must 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 48 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.

First of all, choose a waterproof material that is suitable for home decoration. Waterproof materials are recommended to choose the use of polymer cement-based waterproof coating slurry commonly used in home decoration, that is, the name on the market is: general-purpose, flexible, K11, JS, GS waterproof coating slurry, this kind of product is water-based coating, non-toxic, harmless and pollution-free, simple and fast construction, and cement substrate bonding tight, long service life, strong waterproof effect, moderate and medium significant characteristics.

Choose brands with good quality and good reputation, such as: Leibangshi waterproof slurry, JCDecaux waterproof coating, etc.

Clause. Second, pay attention to the waterproof construction in place. Special attention should be paid to the corner part of the wall to be treated into an arc type and then painted, and the painting can not be too thick (the total thickness does not exceed 2); The pipes should be sleeved with casing, the holes of the executives and walls should be filled with plugging kings, and the waterproof materials should be brushed to the height of the casing 10 and not too thick;

Clause. 3. Pay attention to the height of waterproof painting. Generally, the wall is repainted and brushed 30 high; Paint the wall around the shower area 180 high or to the top of the wall; There is a bathtub where the upper brush is 30 higher than the bathtub.

If you do the above three points completely, you will definitely be able to achieve the waterproof energy of the bathroom.

First, the waterproof process of the bathroom.

One: Brush the waterproof paint for the first time. Before construction, it is necessary to ensure that the ground is dry, and the waterproof coating should be coated with no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off. The coating height is consistent, and the thickness should meet the requirements of the product.

Two: Brush the waterproof paint for the second time. It is important to note that the second application should not be carried out until the first coat has dried, depending on the characteristics of the product. If the interval is too short and the first coat of paint has not yet dried, the waterproofing effect will be greatly reduced.

Three: Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

Four: closed water test. During the closed water test, the water at the highest point of the ground should not be less than 2 cm, and it should be stored for at least 24 hours, and it will be qualified only after observing that there is no leakage. If there is a leak, it needs to be redone, and it must not be negligent.

Second, the bathroom waterproof specification.

1. Ensure that the floor of the bathroom is relatively stable. If you need to replace the floor tiles in the bathroom, after chiseling off the original floor tiles, be sure to level the floor with cement mortar first, and then do waterproofing treatment. This avoids leakage of the waterproofing coating due to uneven thickness.

2. The sanitary indirect joints should be painted in place. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic areas.

3. Wall treatment is also very important. In the general toilet waterproofing treatment, the wall should also be made about 30 cm high waterproof paint to prevent water from penetrating the wall. However, if the wall of the bathroom is a non-load-bearing lightweight wall, the entire wall should be coated with waterproof paint.

4. The waterproof test must be done. After the construction of the toilet is completed, all the sewer in the toilet is blocked, and a 25 cm high "barrier" is built at the door, and then 20 cm high water is poured into the bathroom.

5. Keep the toilet sewer pipe unobstructed. All sewer pipes in the bathroom, including floor drains, plumbing pipes for sanitary ware, etc., should be kept unobstructed.

Specialized in waterproofing layer. Now there are three methods: one is rigid waterproofing. The second is waterproofing. The third is membrane waterproofing. Professionally deal with all kinds of leakage and incurable diseases. Free exchange of leakage management experience.

Test the water first to see if there is any water leakage in those embedded pipe fittings, and then do the leveling layer and waterproof layer.

First of all, the floor of the bathroom should be flattened, then waterproof paint should be applied, and finally ventilation should be carried out to allow the paint to air dry, and finally the waterproof effect should be tested. The details are as follows:

1. Before the waterproof treatment of the bathroom, the ground level of the bathroom should be leveled first, the ground is uneven, and the waterproof coating may be uneven when painting, or the ground is easy to crack because of unevenness, which will crack with the ground even if the waterproof coating is applied.

2. The wall of the bathroom also needs to be waterproofed, generally painted 30cm on the wall from the ground level upwards, so as not to let the water penetrate into the wall to form a resurgence.

3. After the waterproof layer is painted, it needs to cool for a certain time. This is to allow the waterproofing layer to better integrate with the wall surface to prevent damage to the waterproofing layer in the subsequent construction.

4. The waterproof layer is a project to be done before laying bricks, and it is inevitable that the waterproof layer will be damaged during the construction of the back, if it is found that a certain waterproof layer has been destroyed during the test, it should be avoided to smash the wall tiles, but to block the gaps with professional joint materials.

Notes:

1. Pay attention to environmental protection in the selection of materials.

When purchasing waterproof materials, in addition to the requirements of waterproof performance, it is also necessary to clarify its environmental performance. First of all, when buying brand products in brand stores, most well-known brands have anti-counterfeiting marks to make it easy for consumers to distinguish. Secondly, environmentally friendly waterproof materials should have product test reports and product certificates issued by nationally recognized testing centers (CMA), and consumers should pay attention to consultation when purchasing.

2. Do the closed water test twice.

The roller coating of the waterproof layer usually takes only half a day, and after 2-3 days of drying, it is necessary to carry out a closed water test, that is, to store water on the ground for 24 hours, and observe whether there is water seepage from downstairs. It is recommended that consumers do a second closed water test after all the processes such as brick laying are completed to avoid accidental water leakage.

Floor and wall inspectionsGround and wall inspection should be done before the bathroom waterproofing, only after leveling the ground and wall can you enter the next project, and then you must carefully observe the ground and wall, if there are decoration impurities, you must clean up. At the same time, it is necessary to check whether there are impurities in the drainage pipes and sewer pipes, and the impurities in these places should be cleaned up. Only in this way will it not affect the waterproofing of the bathroom, nor will it cause the problem of blockage in the bathroom.

Coating of waterproof paintsAfter the waterproof paint is applied to the floor and wall, it is time to start the waterproof coating. When the bathroom is waterproofed, special attention should be paid to the waterproof treatment of the joints such as sewer pipes, light walls, and flues, and the waterproof function must be strengthened in these places.

The waterproof height of the wall should be painted to a height of more than 1 8 meters, so that even the shower will not cause the wall to be damp, and it will not affect the waterproof layer. After the waterproof paint is painted, wait until it is completely dry to carry out the closed water test, before doing the closed water test, the toilet water outlets should be blocked, and then place about 2cm of water in the bathroom, and the time of the closed water test is 24 hours. When the waterproofing project is completed, the decoration garbage and some discarded tools in the bathroom should be cleaned up.

How to do waterproofing in the bathroom:

1. Use waterproofing agent: use waterproofing agent mixed with cement mortar to do it at the base of the kitchen or bathroom, and after it is dry, then use waterproofing agent mixed with cement ash on the surface of the first brush layer to avoid loopholes in the future.

2. Non-woven fabric: This is a kind of thing similar to cloth, after brushing the base layer with cement mortar thinly, it is directly spread on it, which is an important part of bathroom decoration waterproofing.

3. Use coil: clean the base layer, dry the base layer, spread the coil on the ground, and heat the coil with a spray gun to bond the gap between the coil and the coil. However, the membrane is fragile, and the surface is easy to be broken by the stones when backfilling, resulting in water leakage, and it is not easy to deal with the root of the pipe.

Bathroom waterproofing precautions

1. In order to ensure the flatness of the toilet base, we must remember to use cement mortar for leveling before waterproof construction, because this can avoid the leakage caused by the uneven thickness of the waterproof coating.

2. After the base is leveled, the next step is to carry out the construction of the waterproof layer, so that we should also pay attention to fire prevention, waterproof and other issues.

3. In the process of waterproof construction, we must check the floor drain, water pipe and wall hole one by one, and the root of the pipeline must be caulked according to the requirements during the construction process.

4. Pay special attention to the waterproof construction of the wall, if the wall is adjacent to the bathtub, then the waterproof height must be a little higher than the upper edge of the bathtub, and the shower should meet the height of 180 cm.

5. Before waterproofing, you should pay careful attention to whether the elevation position of the floor drain is correct, if not, you should make appropriate adjustments.

1.Choose waterproof materials: When decorating a bathroom, it is very important to choose materials with good waterproof properties.

Commonly used waterproof materials include anti-waterproof coatings, waterproof membranes, waterproof adhesives, etc. It is recommended to choose a material with strong waterproof performance. 2.

Do a good job of waterproofing: When decorating the bathroom, be sure to do a good job of waterproofing. The waterproofing layer is the key to preventing water leakage, and if the waterproofing layer is not strong, it will lead to water leakage, which will affect the use of the bathroom.

3.Pay attention to details: When decorating the bathroom, you also need to pay attention to some details.

For example, water pipes, sewers and other places should be sealed to avoid water leakage. At the same time, the floor and wall of the bathroom should also be waterproof to avoid water leakage. 4.

Regular inspection: After the renovation of the Wei Bi brothers' room is completed, the waterproof layer is regularly checked, and the problems are found and repaired in time to avoid water leakage. At the same time, it is also necessary to pay attention to the ventilation of the bathroom, keep the bathroom dry, and avoid damp disturbance.

The bathroom is a place that is prone to water accumulation and dampness, and it is necessary to do a good job of waterproofing. Here are some ways to waterproof your bathroom:

1.Waterproof glue: Use waterproof glue to treat the corners and joints of the bathroom to prevent water leakage.

2.Waterproof coating: On the bathroom floor, wall, bathtub, etc., use waterproof coating to cover the waterproof effect.

3.Waterproofing membrane: Before the construction of the ground and wall, it is necessary to lay the waterproof membrane on the base layer, and press it for construction after laying it to make up for all the joints and eliminate leakage.

4.Half-height wall: The design of the half-height wall can effectively prevent the water from causing trouble, and the tiles of the bathroom are only laid down to the position of the half-height wall.

5.Correct drainage: When installing toilet drainage equipment, drainage construction should be carried out in accordance with the requirements of the design drawings to ensure that the drainage equipment is consistent with the sewage discharge capacity of the toilet equipment.

The above are some of the methods for waterproof toilets, if you are not sure how to operate, you can seek professional help to complete the tour. Doing a good job of waterproofing can greatly increase the service life of the bathroom, prevent moisture, mildew, keep dry, and is more conducive to protecting the health of family members.

The methods of waterproofing the bathroom are: waterproofing the ground and waterproofing the wall.

1. The ground is waterproof.

Ground waterproofing mainly refers to the moisture-proof treatment of walls and floors. When making the wall moisture-proof, it is necessary not to damage the original wall structure, otherwise it is easy to cause leakage; In addition, it is also necessary to pay attention to the ventilation conditions of the bathroom, so that there will be no mildew and other conditions due to moisture; Finally, it is necessary to do a good job in the closed water test of the bathroom.

2. Make the wall waterproof.

First of all, check whether the wall and floor tiles of the toilet are firm and flat, and whether there are cracks. If these conditions exist, they need to be patched.

The second thing to do is to fill all the gaps in the toilet with plugging agent and compact and wipe it, and then apply cement slurry to the joints between the basin and the ground, and finally apply a layer of polyurethane foam plastic glue on the back of the tile for bonding and fixing.

Causes of waterproof leakage in the bathroom

Bathroom waterproof layer leakage: If you want to determine whether it is a waterproof problem, you can carry out a closed water test to detect the floor drain of the bathroom floor, and put the 3cm high water source wide in the bathroom, after 12 hours, see if the water level has dropped, if the water level has not dropped, it may be a problem with the water pipe, on the contrary, if the water level has dropped, it means that the waterproof layer has a bright problem.

Sanitary ware quality problems and installation problems: when buying cracked skin to buy sanitary ware, do not choose too poor quality sanitary ware, because it is easy to leak water when in use, as we all know, the joints of the toilet are underground, and water leakage will inevitably occur when draining, and water will penetrate into the wall through cement mortar.
