How to remedy the waterproofing of the bathroom wall

1. If the wall is not waterproofed, you need to put the wall close to the root of the wall.

Bricks and floor tiles are knocked open, waterproofed again, and tiles are pasted after the waterproofing is done after the water test is successful.

2. If the waterproofing at the bottom of the wall is not done, you need to knock all the floor tiles open and do the waterproofing again.

3. The waterproofing of the wall is not done due to the damage of the drainage pipe, and the new water pipe needs to be replaced.

The right way to waterproof your bathroom.

1. Brush the waterproof paint for the first time.

Before brushing the paint, the base surface should be cleaned clean, there should be no foreign matter, and the base surface should be kept dry, so as to ensure that the coating and the base surface are more tightly bonded, and there will be no falling off in the later stage. When painting, it is necessary to ensure that the painting height of the entire base surface is the same, and the thickness of the painting must meet the construction requirements.

2. Brush the waterproof paint for the second time.

After the first coat of paint has dried completely, start brushing the second coat of paint. This will make the waterproofing effect better.

3. Lay a protective layer.

If it is just a simple waterproof layer, it is easy to be damaged in the later construction. Therefore, a protective layer should be made on the surface of the waterproof layer. The protective layer should be fully covered with the waterproof layer to ensure that it is tightly bonded with the base layer, so that the effect will be better.

4. Closed water test.

After completion, the closed water test must be done, and there will be no water leakage after the experiment, so as to be qualified. If there is a water leak, it needs to be re-waterproofed.

The bathroom is a space with more water, if the waterproof is not done well, the comfort of life will be greatly affected, so it must be waterproof before it can be used normally.

If the waterproofing of the bathroom wall is not done, it should be redone or brushed with film waterproofing.

As we all know, the most important thing in toilet decoration is waterproofing. If you cut corners during decoration and don't do waterproofing, there will be a lot of trouble later. After using it for a period of time, it is easy to seep out of the ingots, fall off the tiles, mold and other phenomena, which seriously affects the use experience of the toilet.

First of all, we need to look for the cause of the water leakage, whether it is a problem with the water pipe or the waterproof layer. For example, the leakage part is not waterproof; The height of the waterproof layer is 180cm lower than the conventional standard; Later pipeline construction affects the waterproof layer; waterproofing material quality problems and so on.

Once the location of the leak is located, it is necessary to remediate it according to local conditions. If there is a crack in the pipeline, the pipeline should be replaced in time; If there is a leak at the pipe joint, it should be reinforced; If the waterproof layer is too low, you need to make a high waterproof layer; If you use waterproof products such as sealants, you should have a clear understanding of their brand. If you have doubts about the quality, the first choice is well-known big brand products, which are more guaranteed.

If it is waterproofing, pay attention to the details: whether the base layer is smooth and clean; Whether the waterproofing of key parts such as the connection of the ground wall and the connection of the sewer mouth is done well should be checked many times; The wall waterproofing project shall not be less than 180cm, and the closed water test shall be carried out within 24 hours after the completion of the construction.

The water level height and time of the closed water experiment should be carried out in strict accordance with the standard. Bathroom waterproofing should be resolutely implemented to prevent the mainstay, the principle of combining water fortification and investigation, in the decoration process, we must do a good job of active waterproofing, there must be no water leakage, in case of water leakage. Otherwise, if you find a water leak after moving in, it will not only be troublesome to do waterproofing, but the cost will be 3-5 times that of active waterproofing.

Bathrooms are not waterproofed. Probably still being renovated. I guess after pasting the floor tiles, I found that it was not waterproof.

That's good. We are renovating.

We can still do it. Let's rebuild it, cut all the way down to the bottom of the caisson. Don't just knock out the floor tiles, waterproofing the screeds, or overhead prefabricated panels.

Because in this way, the water seeping into the pores of the tile, do not go, accumulate in the mortar layer, for a long time, it will breed bacteria, mold, and serious water will enter from the threshold, the inlet and outlet of the pipe, resulting in the door of the bathroom, the opposite aisle, the basic surface of the living room and the room putty moisture absorption, resulting in the delamination of yellow and black bubbles, and so on.

Knock the tiles off and re-apply them to waterproofing. The bathroom must be waterproof, if the room is not waterproof, it must be remedied in time, otherwise the downstairs residents will become a water curtain hole, resulting in unnecessary disputes.

In such a situation, you can choose to lay tiles on the wall of the bathroom, because this can play a very good role in thermal insulation, and then it can also play a waterproof effect to a certain extent.

You can knock down the wall of the bathroom and re-do the relevant waterproof layer work, which is relatively difficult.

The bathroom must be waterproof, which is a very important process, the waterproof layer should extend from the ground to the wall, 250mm above the groundThe 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, and the general thickness shall not be less than, and the waterproof surface of the coating film is not blistered, does not flow, is smooth and has no concave and convex, and the joints of pipe fittings, sanitary ware feet, floor drains, and drainage outlets are tightly closed, and the end is smooth and does not leak. After the waterproofing project is completed, a 24-hour water storage test must be done.

1. First of all, we have to look for the leakage point and see if it is a problem with the water pipe or the waterproof layer. For example, the leakage is not waterproof; The height of the waterproof layer is lower than the conventional standard of 180cm; Later pipeline construction affected the waterproof layer; There is a problem with the quality of the waterproofing material, and so on.

2. After the location of the water leakage is found, it is necessary to remedy it according to local conditions. If there is a crack in the pipeline, we must replace the pipe in time; If the pipe connection is leaking, we need to strengthen it; If the waterproof layer is too low, we have to redo the high waterproof layer; If you use seam patches and other paint waterproofing products, you should have a clear understanding of their brand. If there is any doubt about the quality, give priority to the products of well-known brands, which is more guaranteed.

3. If it is redone waterproof, pay attention to the details: whether the base layer is smooth and clean; Whether the waterproofing of these key areas such as the connection of the ground wall and the connection of the sewer mouth is in place, it is necessary to check it several times; In the case of wall waterproofing work, it must not be less than 180cm, and a closed water test will be carried out 24 hours after the construction is completed. The water level height and time of the closed water test should be carried out in strict accordance with the standard.

The question didn't say that it was a point, it was not done, what should I do?

1. Take it down in the sanitary ware, reinstall it, and pay attention to the connection with the sewer pipe must use auxiliary materials such as waterstops;

2. Remove the 3--5cm area around the floor drain to make a cement-based waterproof material.

3. Use chemical grouting to plug leakage, punch and grouting on the roof of the neighbor's bathroom, or grout in the tile joint of the bathroom;

Fourth, the use of color tile grout, on the existing gaps, and with cement-based waterproof materials or JS waterproof materials in other places (nozzles).

Fifth, the materials can be bought in the construction market.

The wall of the bathroom needs to be waterproofed, which is the standard of architectural decoration, which can not be ignored, and it will also affect your residence if you do not do waterproof for a long time, because there must be a room next door to your bathroom, and there is a simple decoration on the wall. If your hygiene has not been waterproofed for a long time, the water on the bathroom wall will easily corrode and affect your other rooms, so it is necessary to do waterproofing on the bathroom wall.

Can't say no. The waterproofing built by the older generation was not waterproofed and there was no leakage. It's not that if you don't do waterproofing, it will definitely leak, but the purpose of doing it is to prevent leakage. Generally, no one will go to the expo to save some money and will not leak the risk, so they all choose to do waterproofing.

The walls have been renovated, right? There is basically no effective way to remedy the waterproofing of the original base surface of the wall without demolishing the decoration, or the above reason, if you don't fight, it will not leak the risk, it is recommended to demolish it and redo the waterproofing. Otherwise, once it leaks, the loss will not be so little as dismantling and redoing.

Suggestion: It is recommended to paint the wall shower to the top, and the other positions to 30cm high. Use polymer cementitious waterproofing paints.

If you want to solve the problem completely, the best way is to knock the tiles and redo the waterproofing. After all, it is inevitable that the bathroom should use water frequently. It's troublesome, but it's done once and for all. I hope my answer is helpful to you!

1 In general, when it is not very humid. If your wall has been renovated, and because of cost and other reasons, you are not willing to dismantle and redo the waterproofing, then don't do it, no matter what.

2 If the wall inside the bathroom is not done, the wall outside the bathroom can also be painted and waterproof to achieve the effect of waterproof and moisture-proof.

I'll give you some advice:

1.Knock on the wall tiles with your hands and find that there are many hollow drums, which proves that the tiles are not pasted well, and they should be chiseled and waterproofed.

2.I didn't find a lot of hollow drums, which proves that the porcelain *** plays a certain waterproof role, remedy: use acetic acid (household vinegar can) to infiltrate into the tile, and then apply water glass (chemical name sodium silicate) repeatedly to coat the sassafrass so that the acid meets the sodium silicate will react into a firm silica gel.

Silicone can fill the holes that may seep water and play a waterproof role.

The wall is vertical, as long as there is no hollow tile at 1 point, the problem of water seepage will be solved after the above treatment. Then, if the opposite side of the wall is not painted white, you can make up the waterproof first and then make it white, so that the other wall will not produce mildew spots in the future.

I am a team to receive a request for help, to give you advice, please refer to.

In fact, the bathroom does not have to be waterproof, if you do not take a bath in the bathroom, and it is dry and wet separation, there is no need to do it at all.

If it is not the above situation, try to do a good job of waterproofing. How to do waterproofing upstairs has been answered very completely. If it is not done beforehand, there is no remedy other than demolition, and it can only avoid the important and light.

You can learn the kitchen and go straight to the water. For example, the washing machine goes straight to the drain, the basin goes straight to the drain, and the bathtub or bath room (with a bottom baffle) goes straight to the drain. In this way, the water accumulation in the bathroom is basically avoided, and of course, there will be no problem of water seepage.

Except if there is an accident (the faucet is forgotten to turn off, the sewer pipe is not ready to drain).

If you decide to dismantle, it is best to choose soft waterproofing, now "Oriental Yuhong" is a good soft waterproof coating, which can be used as a reference. If the water doesn't leak, basically don't think about it, after all, it's something that is eliminated.

It should be remedied, try pasting waterproof wallpaper.

If the waterproof layer of the bathroom is leaking, you need to remove the original tiles, clean the base surface, level the ground with cement mortar, and then do further waterproofing. Generally speaking, the waterproof height of the bathroom wall is 180 cm, and the waterproof coating of the non-shower wall cannot be less than 30 cm in principle. However, in order to strengthen the waterproof effect, it is recommended to achieve a uniform height of 180 cm.

Toilet waterproof construction lead bumper process 1, toilet waterproof construction process.

Substrate treatment - detailed additional layer construction - first layer coating film - second layer coating film - first test - protective layer construction - second test - project quality acceptance.

2. Process analysis.

1) Grassroots treatment.

There is no floating soil, sand and other dirt on the surface of the base layer, and the surface should be smooth and not loose; The radius of the yin and yang corners is ground into smooth small fillet corners; The surface should be flat and not loose.

2) Detail additional layer construction.

Use a brush to waterproof and plug the material, and evenly brush the weak parts that are easy to leak such as the root of the pipe, floor drain, and yin and yang corners. At the junction between the ground and the corner of the wall, on the waterproof membrane, brush twice to apply the waterproof material.

3) Coating film with a roller or brush to start painting; The first layer of coating film is thinly coated, and the direction of the coating film of the second layer is perpendicular to the direction of the first coating film. Special parts such as corners, seams, and deformation seams must be carefully brushed to meet the requirements, and the thickness of the coating film should be uniform and tightly closed, and no bottom, bulging, falling off, cracking, warping and tight sealing are allowed. The installation specification requires that the waterproof thickness of the coating film is lower.

4) Water test.

After the waterproof layer is dried and solidified, a ridge of bricks is built on the threshold for a 24-hour closed water test to see if there are wet water spots on the roof downstairs, and if not, it proves that the waterproof construction is qualified.

3. Protection of finished construction products.

1) Non-staff are not allowed to enter the site, and construction personnel wear soft rubber-soled shoes.

2) The trolley legs used in construction should be bandaged, and if the waterproof layer is set up with a temporary shelf, the lower mouth of the shelf pipe should be paved with a plate to prevent damage to the waterproof layer.

3) After the acceptance of the waterproof layer, fine stone concrete or mortar can be poured directly on the waterproof layer as a rigid protective layer, and the construction equipment such as trolleys or shovels must be prevented from damaging the waterproof layer.

4) If there is local waterproof layer damage during construction, corresponding remedial measures should be taken in time to ensure the quality of the waterproof layer.

5) Properly arrange various construction sequences, strictly prevent the completion of the waterproof layer and then drill holes, damage the waterproof layer, if due to the improper arrangement of the chain row, damage the waterproof layer, should be repaired in time.

6) Floor drains, toilet buckets, squatting pits and drains should be kept unblocked, and no mortar and other construction waste are allowed to be blocked.

7) After each construction, the construction equipment must be cleaned carefully in time.
