How to do waterproofing in the kitchen bathroom

1.When the base surface is uneven, it needs to be repaired. Yin and yang corner areas, bends and other uneven needs to be leveled, as well as the removal of parts should be repaired and smoothed first, if there are cracks and seepage parts of the base, appropriate plugging methods should be used to repair first.

2.Base surface treatment. The base surface layer must be intact and free of dust, remove thiopine particles, and the surface can be moistened with water before construction, but no open water can be left.

3.Waterproofing slurry mixing. First open the strong waterproof slurry cover, take out a package of waterproof slurry and a bag of powder inside, slowly pour the waterproof slurry in, then pour the powder in, and stir it with an electric mixer until the slurry is uniform and particle-free.

4.Started painting part of the wall with waterproofing slurry. First, the corners and deformed parts of the pipe are reinforced, and then a large area is applied.

5.Waterproof painting order and tips. 1. First evenly paint the waterproof slurry on the wall to make it completely bonded to the wall, and the thickness of the coating film is about 1 mm or less, pay attention to avoid missing brushes.

2. After the surface of the first layer of waterproof slurry is dry (about 2 hours after the hand touches the hands), use the same method to paint the second time in the staggered direction, at least 2 times, and 3 times for those with high waterproof requirements. (Thickness of waterproof coating film.)

Sanitary home waterproof 3 times, it is recommended that the bedroom wall between the brush to the top, the rest of the part is higher than the meter. This is both waterproof and moisture-proof. If there is no floor drain in the kitchen, you can not brush it, and if there is a floor drain, you can brush it to more than 30 cm, because it is still a dry area.

All waterproofing should pay special attention to the connection between the floor drain and the drain when painting!

How to do toilet waterproofing work well? Bathroom waterproofing should be constructed in accordance with the standard process and process The effect is good Waterproof standard process flow (key points): Grassroots cleaning The wall root and the perimeter of the pipeline need to do a waterproof additional layer Painting Closed water test Waterproofing is a hidden project, is the top priority of foundation construction, landscape decoration reminds everyone to pay attention to the following points when accepting:

First, the waterproof layer on the ground should extend to the wall surface back 30cm, the waterproof layer of the wall in the shower or connected room shall not be less than 2000mmX1200mm, and the waterproof height of the bathtub wall shall not be less than 1400mm; Second, the waterproof layer of the wall needs to be brushed and then tiled, and the air defense drum should be affixed; Third, the ground waterproofing needs to be closed for 24 hours, and there is no leakage; Fourth, the whole brick wall must be painted with special tile adhesive on the back of the brick. How to do bathroom waterproofing work well, now do you know the answer?

1. To deal with the base layer, mainly to clean the construction site, if there are cracks or hollow drums around the pipeline and floor drain, it needs to be chiseled into a "V" groove in order to be repaired. After the base surface is cleaned, sprinkle some water on the whole to moisten it.

2. To repair the key parts, this is because the joints between the wall and the ground, as well as the joints between the sewer pipe and the ground are the most prone to water leakage, so it must be carefully treated before waterproofing, and there can be no sloppiness. It is generally recommended to use special repair mortar for kitchen and bathroom to make "R" corners, and fill in these leaky places.

3. The whole should be waterproofed, and after the first two parts are repaired, you can use a special durable waterproof slurry for the kitchen and bathroom, the purpose of which is to achieve a better waterproof effect. If it is a lightweight wall, it must be painted at full height. The kitchen wall should be at least one meter higher, and the water parts such as the vegetable sink should be higher than the water outlet, and the door frame and sill stone should also be painted in place to prevent moisture return.

4. Do a closed water test. After the waterproof layer is completely dry, all the sewers should be blocked, and a "low wall" should be built at the entrance for water injection test, and the water injection height should be about 20cm. Wait for 24 hours before checking, if the water level does not drop significantly, it means that the waterproof quality is qualified.

On the contrary, it is necessary to find out the leakage point, and after repair, it is necessary to do a closed water test again until there is no leakage.

1. Bathroom waterproof construction steps.

Step 1: You can use a slightly coarser cement to base the foundation first, and then brush the waterproof paint after the cement is dry. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes.

Step 2: Mix the powder and liquid material evenly, and brush the bubbles if there are bubbles when brushing the paint.

Step 3: When brushing the paint, brush it from the same direction, wait 1-2 hours, and then brush the second coat. When brushing the second layer, the direction of the brush should be opposite to that of the first layer, so that the best coverage can be achieved.

Step 4: You can brush it several times, which can increase the density and fill the gaps. Some people think that the more layers of waterproof paint the better, or even brush six or seven layers, but in fact, this is not good, the paint is too thick and easy to crack.

Step 5: Wait for one day before taking a waterproof test.

Step 6: When doing the waterproof test, you should first fight with your downstairs neighbor.

Say hello, then plug the drain, fill the ground with water, and wait an hour to ask your downstairs neighbor if there is a leak. If there is a water leak, the waterproofing layer should be rebuilt. If the waterproof test is qualified, it can be tiled.

2. Precautions for waterproofing in the bathroom.

1. In order to ensure that the bathroom floor is flat, it must be leveled with cement mortar, and then waterproof, so as to avoid leakage caused by uneven thickness of waterproof coating.

2. After leveling, when carrying out the construction of the waterproof layer, it is necessary to pay attention to fire prevention and waterproofing.

3. When doing waterproof construction, the floor drain, pipeline, and wall hole should be carefully inspected, and the root of the pipeline must be caulked according to the requirements during construction. 4. The waterproof treatment of the wall should also be noted, if the wall and the bathtub are adjacent, then the waterproof treatment height should be higher than the upper edge of the bathtub, and the shower should reach a height of 180cm.

5. Before doing waterproofing, pay attention to the correct position of the floor drain elevation.

6. To ensure that the sewer is smooth, the sewer pipes in the bathroom, including floor drains and toilet sewer pipes, must be kept unobstructed.

Bathroom waterproofing project is currently home decoration is more prone to problems, to pay special attention to these sensitive areas in the home decoration. At present, there are many kinds of materials used for toilet waterproofing, and basically the waterproof effect is not bad, but it is necessary to pay attention to the specific construction details of bathroom waterproofing, and repair the problem in time.

Kitchen and bathroom waterproofing coatings (Dubabe home improvement waterproofing coatings) polymer cementitious has become the protagonist of the waterproofing coating market.

Toilet waterproof construction technology, process and precautions.

1. Before the bathroom decoration construction, it is necessary to determine the design of the water circuit, and the possibility, feasibility and availability of the design scheme must be considered in detail. Lay the water, electricity and heating pipes first, and then level.

2. When doing waterproof construction in the bathroom, the base layer should be treated first. Remove the original decoration materials, clean up the floating soil and cement, first use cement mortar to level the ground, and then do waterproof treatment, requiring a smooth and dry surface. This avoids leakage of waterproofing coatings due to uneven thickness.

3. When paving the waterproof coating, it should be painted evenly, and there can be no missing brush, bulging and falling off, and the thickness of the waterproof coating layer shall not be less than, otherwise it will affect the waterproof effect.

4. Pay attention to the waterproof dead angle during construction, the joints between the walls and the ground, and the joints between the water and water pipes and the ground, which are the most likely places to cause problems.

5. After the construction of the waterproof layer in the bathroom, block all the sewers in the bathroom, build a 25cm high barrier at the door, and then pour 20cm high water into the bathroom.

After hours, check whether there is leakage on the surrounding walls and ground, if there is leakage, it needs to be repaired in time, and then do a 24-hour water test after repair, no leakage can enter the next stage of construction.

7. After the completion of the water shielding test, it usually takes 5-7 days (it takes 5 to 7 days for the waterproof coating to form a waterproof membrane), and then a layer of cement mortar protective layer is made on the waterproof coating layer, one to protect the waterproof coating layer, and the other is convenient for veneer bricks, and pay attention not to destroy the waterproof coating layer that has been done.

8. After the protective layer of cement mortar is dry, you can pave the wall tiles or spray paint or pave the anti-wallpaper on it for normal decoration.

Are you decorating yourself, there are waterproof ones in the building materials market, but which one is easy to use is not clear, how to brush it up without leakage also needs experienced people to do, waterproof approaching is a big deal, it is recommended to find a professional to do.

The basic construction process of bathroom wall tile paving is: wall base leveling treatment - wall waterproofing (brushing waterproof coating) - wall brushing - paving tiles.

The floor and walls of the toilets, kitchens, balconies and all floors and walls of the first-floor dwelling, the basement floors and all walls should be treated with moisture.

3. Calculation of waterproof area.

Waterproof area of toilet and bathroom (square meters) = (floor perimeter of toilet and bathroom - width of door) meters (height) + (ground area).

Waterproof area between kitchens (square meters) = (kitchen floor perimeter - width of the door) meters (height) + (floor area).

Balcony waterproof area (square meters) = (balcony floor perimeter - width of door) meters (height) + (ground area).

4. How to make waterproof.

First of all, the wall or ground is flattened, cleaned, and after drying, the waterproof coating material is poured into the nail material and stirred for 3-5 minutes, and then evenly coated on the wall or ground, and can be dried.
