How to waterproof the bathroom

Hello, bathroom waterproofing process: do two layers of waterproofing on the entire bathroom floor, 30 cm on all sides to do waterproofing, and the shower area is 1100*1800.

Bathroom waterproofing, generally call professional waterproof construction personnel to do, waterproof after the way to do the test, the general put on the water does not leak good.

The bathroom is dealing with water, so the waterproof facilities must be done, mainly the sewer must be kept unobstructed and not blocked, especially when taking a bath, if it is not smooth, there will be a lot of water, so the waterproof highlight of the bathroom is to do a good job of sewer.

It is to brush waterproof materials, and to standardize the construction of real materials.

Polymer polypropylene is insufficient!

The waterproofing project of the bathroom is the place where the current home decoration is more prone to problems, and special attention should be paid to the "sensitive areas" in these home decorations. At present, there are many kinds of materials used for waterproofing in toilets, and basically the waterproof effect is good, but it is necessary to pay attention to the specific construction details.

Make a flat floor. If you want to replace the floor tiles in the bathroom, after chiseling the original floor tiles, you should first level the floor with cement mortar and then do the waterproofing treatment. This avoids leakage of the waterproofing coating due to uneven thickness. 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.

During construction, the joints should be painted in place.

Treat the wall. In the general waterproofing treatment of toilets, the wall should also be coated with a waterproof paint about 30cm high to prevent water from penetrating the wall. If you use two screens, the two walls that are connected should also be painted. If you use a bathtub in your home, the wall adjacent to the bathtub should also have a higher height of the waterproof paint than the top edge of the bathtub.

Waterproof experiment. After the construction of the toilet is completed, all the sewers of the toilet are blocked, and a 25cm thick "threshold" is built at the door, and then 20cm high water is poured into the bathroom. After 24 hours, you will check the surrounding walls and floors for leaks.

--- relevant knowledge.

The waterproof layer of the bathroom is very easy to be damaged during decoration, especially the joints between the sewer pipe and the floor slab are the most likely to leak, which will bring trouble to the residents on the lower floor. The traditional practice is a waterproof layer of two felts and three oils or three felts and four oils. In the decoration project, this kind of hot processing has been basically eliminated.

At present, most construction units use waterproof coatings. Although this is simpler than the construction procedure of two felts and three oils, there is a strong peculiar smell in the construction, and the floor pipe joint is slightly larger, which will cause hidden dangers. The best solution is to mix the cement mortar with a waterproofing agent, with South Korea's "PSC Laoyal" waterproofing agent as the best, after the cement and sand are mixed in a ratio of 1 3, then mixed with waterproofing agent instead of water, and then the construction can be done like plastering the wall and plastering the ground, which is simple and reliable, and will never produce cracks and aging.

Buying a new house at home is inevitable to decorate. Waterproofing is inseparable from renovation at the same time, especially in the kitchen and bathroom. It is also necessary to do a good job of waterproofing.

So how to make the bathroom waterproof? First of all, 1. Before waterproof construction, it is necessary to do a good job in the base treatment of the wall, and ensure that the surface is not pulverized, there is no peeling, no drumming, etc. At the same time, the surface of the base layer must be clean and free of dust, and there must be no debris and stains that affect the adhesion of the paint, such as release agents.

2. The first step is to brush the waterproof paint for the first time. Before construction, it is necessary to ensure that it is clean and dry, and the waterproof coating should be fully coated, and the combination with the base layer should be firm, and there should be no cracks, bubbles, and falling off. 3. It should also be noted that the height of the brush should be consistent, and the thickness should also meet the requirements of the product.

Generally, the dry area should be 30 cm waterproof, and the shower area should be more than 1.8 meters high, and if you use a bathtub, it should be higher than a bathtub. 4. In the second step, brush the waterproof paint for the second time. It is necessary to wait for the first coat to dry before the second coat.

5. The third step is to lay a protective layer. It is necessary to put a protective layer on the surface of the waterproof coating, and the protective layer should be completely covered. 6. The fourth step is the closed water test.

After the construction is completed, all the sewers in the toilet are blocked and the closed water test is carried out. 7. If there is no leakage on the walls and ground around the bathroom within 72 hours, it means that the waterproof quality is good, on the contrary, the leakage point should be found and repaired.

1. Brush the waterproof paint for the first time. Before construction, ensure that the construction site is clean and 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.

2. Brush the waterproof paint for the second time. Note that there needs to be a certain time interval between the second anti-fraud and stuffy water coatings, and the second pass can only be carried out after the paint is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

3. 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, without omission, firmly combined with the base layer of the mountain, no cracks, no bubbles, and no falling off.

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

5. Grassroots treatment, cleaning up the lease and closing bends. Do leveling layer, bonding layer, detail additional layer, acrylic waterproof layer, water storage test, protective layer construction.

Waterproofing is divided into three steps, base surface treatment - foot board material - painting material, pay attention to the nozzle, wall corner, toilet around the place that is easy to cause vibration is the need to use flexible waterproof reinforcement, other places brush general waterproof, more details welcome to leave me a message.

1.Clean the base surface and sprinkle it with water to moisten but there should be no stagnant water.

2.Prepare the quick-setting repair mortar, add water to the quick-setting repair mortar according to the ratio of 3:1, and the adjusted mortar needs to be used up within 5 minutes. The quick-setting repair mortar is evenly brushed on the yin and yang corners, pipes, sanitary ware, floor drain periphery and other parts that are prone to water seepage.

3.Pour the waterproof liquid and powder into the bucket, then stir evenly with an electric rod, let stand for 3 minutes and stir again for later use.

4.Paint waterproof coating, the bathroom floor needs to be done, the wall needs to be painted at least to the meter, it is recommended to do the full height. Brush 2-3 times, the total thickness is in.

5.After the waterproof coating is dry, it is recommended to make a protective layer of mortar in order to ensure strength.

After the hour, sprinkle water for maintenance, and the part exposed to direct sunlight needs to be covered.

Buy a 911 or K11 and just brush it up. It's so convenient, if you use it at home, you can use a better material, Qinglong's HG203 is the best material for environmental protection and waterproofing.

The problem of toilet waterproofing can be seen on the Jianke waterproof website, which has detailed construction drawings, construction technology and prices.
