How to make the bathroom waterproof and not leaky?

Three points of material and seven division of labor. Waterproofing mainly depends on the construction steps and details. Do a good job of detailing first.

Bathroom waterproofing is a problem that should be paid great attention to in the decoration process, we must find a regular professional master construction, good construction technology and good waterproof materials can achieve good waterproofing.

To buy a good waterproof material, find a professional master to do it, it is recommended not to do it yourself.

The ground is flat, the granular substances are all removed, and then the waterproof glue is played, but the waterproofing agent is dried and the water is released to test the leakage in the bricks.

General direction: good materials, good labor.

First of all, about the height: consider the safety of the waterproofing of the toilet and the overall waterproofing effect. Generally, the shower or sprinkler head is installed at a height of about one meter, if the waterproofing is low, the long-term spraying will cause water to soak the wall, so that the wall mildew, wall decorative layer paint or brick peeling off and other problems, so that the waterproof effect can not be achieved.

In principle, non-shower walls can be made to meters, but in order to strengthen the waterproof effect, we all uniformly achieve meter height, and the cost does not increase much. In addition, for the light wall and self-built light wall of the toilet and bathroom renovation, it is recommended that the waterproof height should be topped.

About the optional materials:

At present, the management of the building materials market is not standardized, and there are many fake and shoddy products on the market. The real environmentally friendly waterproof material should have the Ten Ring Certification or CTC Environmental Protection Certification and Product Certificate. In addition, when buying waterproof coatings, you should pay attention to the service measures of the manufacturer.

Generally, regular manufacturers will have relatively standardized pre-sale, in-sale and after-sales service when selling products. All kinds of waterproof coatings sold on the market, as long as they meet the national standards, should be used for home decoration waterproofing. These paints have their own advantages, and you can choose to buy them according to your needs.

Polyurethane waterproof coatings have good elasticity and elongation, and in terms of coating film quality, they are the most prominent comprehensive properties in all kinds of coatings, but the construction period is longer and the price is more expensive. It is worth noting that most of the miscellaneous products sold on the market are not pure polyurethane, and the environmental performance is not very good; Acrylic waterproof coating, easy construction, environmental protection, good coating performance, moderate price, generally home decoration waterproof will use this kind of coating; JS is a kind of rigid and soft waterproof coating, which is convenient for construction, environmentally friendly and non-toxic, and is also a good choice; Waterproof mortar coating, high film strength, good combination with the base layer, can directly paste ceramic tiles, economical and practical. However, because it is a rigid waterproof material, it is not suitable for the decoration of new houses that may have settlement.

In general, among all kinds of coatings, the best performance is polyurethane, the best cost-effective is acrylic and JS coatings, and mortar coatings are economical and practical.

About labor: You need to find a regular company or a professional waterproof practitioner, which is more professional. It's not like many people think that it is enough to paint two or three times, and many grassroots treatments are very important, especially many small details.

The order in which to do waterproofing:

Clean the base and detailed component node treatment, apply the first waterproof paint, apply the second waterproof paint, close the water test, and do the protective layer.

I am specialized in decoration, and I have more than 10 years of experience, and there are many new and old customers, because we are very responsible. Let me talk about the waterproof and non-leaking, the most important thing is the foundation treatment, and the most important thing in the foundation treatment is to have a solid and sloped ground. This allows the water that has penetrated under the tiles to drain away along the slope in the first place.

The choice of waterproof materials, generally use waterproof coatings, two-component, if the wall is brushed, and the floor tiles are on the wall in the later stage, then please choose rigid waterproof coatings; If the floor is easily deformed, for example, the thickness of the floor heating backfill is insufficient, then use a soft waterproof coating, but be careful not to brush the wall more than 30 cm. The front and rear processes are coordinated, the hydropower process, the waterproof area is less pipelined, and the slope is easy to do waterproofing; In the ceramic tile process, the side of the door stone is blocked to prevent overflow. Paying attention to these points, layer upon layer of fortification, waterproof not only does not leak, but also has no stagnant water and no peculiar smell inside, and the service life is still long, which should be the new pursuit of waterproofing!

To ensure the flatness of the bathroom floor, if the ground is found to be uneven before the waterproof construction, we must do leveling treatment, the main purpose is to prevent the waterproof effect from being affected by the uneven thickness of the waterproof material. The ground should be cleaned up, because the flexible waterproof is mainly bonded with the ground, if there is too much dust, it will affect the adhesion, and if there is particle garbage, the waterproof layer will be damaged, so before the waterproofing, the ground sanitation must be cleaned in place. The corners of the wall, the root of the sewer pipe and other details should be treated specially, because the bathroom leaks, mainly in these places, so we must treat these small places carefully when we paint waterproofing, do not be exposed, otherwise it will affect the overall waterproof effect.

Sort out the garbage on the ground surface of the bathroom, so that it is clean and free of large particles, and if there is a sanding phenomenon, treat the waterproof base surface in advance, and pay attention to the slope. The waterproof base surface is dry thoroughly, start to do the waterproof coating of the wall and ground, after the first time it is dry, only start to brush the second waterproof, the height is generally above, the corner needs to be done arc treatment, not right angle to do waterproofing, note that many waterproofs are not the same as the wall and ground, most brands are blue walls and green spaces (blue brush wall, green brush ground). After the waterproof is dry, notify the property or the building management, start to store water, the height is generally 20 cm high, and after 72 hours, notify the downstairs and the property to go downstairs to inspect together, no water leakage to sign and accept, if there is a leakage to drain the water, dry and re-do the waterproof, and then accept again.

It is also necessary to pay attention to the "U" shaped submersible bend, a detail that prevents the backsmell from entering the bathroom in the later stage.

Wet the entire floor and the walls with water (the purpose is to clean the sand and dirt on the floor and walls). Mix with water without leaking and stir well, slightly thinner. The place where the wall is grooved, the yin and yang corners of the wall, the sewage pipe wall, and the sewer pipe wall do not leak the water to the upper layer.

Stir well with water without leakage, paint the entire floor to one side, and turn the wall 30-50 cm. Wait for the water to dry thoroughly, before the first waterproof coating construction, the entire ground is painted with waterproof paint, and the wall can be made meters high. Wait for the first waterproof coating to dry thoroughly, and then carry out the second waterproof coating application.

Cross brush with the first waterproof paint (if the first waterproof paint is vertical, the second is horizontal). Closed water experiment, wait until the second waterproof coating is completely dry, carry out the closed water test time for 24-48 hours, pay attention to inform the downstairs at any time to pay attention to whether there is a leakage on the roof, if there is no waterproof construction.

When we renovated our home, I did it myself, because I felt that the waterproofing of the bathroom was still very important. The waterproofing of the bathroom must be done without leakage, which is a guarantee to yourself and a guarantee to the neighbors downstairs, which is not negotiable. First of all, when the walls and floors are flat, it is necessary to deal with the drain drain nozzle first.

The drain nozzle is bowl-shaped, so that the water flow can flow directly into the sewer pipe in the later stage; Clean up the small stones and broken cement blocks on the site to ensure that they are clean before waterproofing; Use a high-pressure water pump to clean all walls, wall roots and floors to ensure that there are no dripping cement shells and floating ash left on the surface; Wrap all outlet nozzles with tape to prevent the nozzle threads from being covered by a waterproof layer; At the same time, all the potholes on the wall and ground are repaired with plugging king or waterproof products, and the yin corners of all walls and floors are painted at the same time to prevent deformation or cracking in the later stage and make waterproof ridges.

First of all, clean up all the garbage, dust. If the base layer is uneven, then leveling, the purpose is to brush waterproof without leaving dead corners, but also to brush evenly. Then there are the drain outlets, the corners of the pipes, and if you can, brush them with the plugging king.

Then start to brush the waterproof glue horizontally, brush it vertically when it dries the next day, and brush it again on the third day. After brushing three times, you can test the water, test the water without any problem on the backfill, find a lowest point, make the base row, and then backfill to find the lowest point, fill with mortar, the mortar is dry, use the plugging king to brush the corners and nozzles, and then repeat the above horizontal and vertical brushes. After drying, backfill it again, take the second row of pipes as the lowest point, make a pot bottom, and the surrounding height is very important!!

The aim is to leave no standing water! Then use the plugging king to brush the edges and corners and the nozzles. Then you can brush waterproof, but also the first horizontal and vertical The third time to brush casually, remember to brush a little higher against the wall, 1 meter is OK, the purpose is to be afraid of penetrating into the next room and causing mold!

That's almost the end of it.

Prepare all the waterproofing materials. Before doing the waterproofing work in the bathroom, the waterproofing material should be prepared. Including waterproof coatings, asphalt, cement, fine river sand, and many more.

When buying waterproof coatings and asphalt, you must shop around, buy those waterproof materials with good reputation and reliable quality, and don't be greedy for cheap. Use cement concrete to smooth the floor of the bathroom, and use cement concrete to wipe the joints between the sewer pipe and the ground in place. Use fine river sand and cement to make cement concrete in a certain proportion, and smooth and plaster the joints between the toilet floor, sewer pipe and the ground with cement.

It is necessary to pay attention to the uniform force and consistent thickness. The thickness of the coating is about 3 cm. After the cement is dry, carefully paint the bathroom floor, sewer pipe and ground joints with waterproof paint.

After the cement on the floor and joints of the bathroom is dry, gently apply the cement with waterproof paint. When coating, it is necessary to pay attention to the uniform coating of the coating, especially the joints are not only required to be uniform but also to be coated thicker.

Choose a good waterproof material, choose a national standard, or a qualified quality waterproof material; And to protect the environment, we can check the certificate, factory report, manufacturer qualification and other information, if you are not at ease, you can go to the Internet to check; It is very important to do a good job of drainage slope, according to the requirements of the drainage slope, according to the location of the floor drain from all sides to the location of the floor drain reasonable drainage slope of about 2%; Carry out waterproof coating construction in accordance with the construction method, pay attention to the protection of waterproof raw materials, can not be destroyed, there are damage, poor appearance and other quality problems can not be used, the surrounding wall height of about 30 cm also needs to be waterproofed, if necessary, you can also increase the height, if there are embedded pipes on the wall, you need to use mixed mortar to fill the chamber and then carry out waterproof construction, if other pipelines need to do protective measures. Special attention needs to be paid to the waterproofing of the connection, connection and joint parts, and it is necessary to do a good job of effective waterproofing, otherwise there will be leakage.
