How to do the waterproofing measures in the bathroom and what are the steps

The practice of waterproofing the bathroom is:

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.

2. Brush the waterproof paint for the second time. The second pass of waterproofing paint requires a certain time interval and can only be carried out after the paint has dried, depending on the coating.

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 a waterproof layer, without omission, and firmly combined with the base layer.

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.

5. Clean up the base layer, do the leveling layer, the bonding layer, and the secondary water storage test.

Bathroom is a hurdle in the process of home decoration, every family can not avoid, waterproof performance is undoubtedly an important criterion for judging the quality of bathroom decoration. Then meToilet waterproofing measuresHow to do it, so that we can worry about it, let's learn together and see the professionalToilet waterproofing measuresWhich ones are they.

Buy auxiliary materials such as professional waterproofing products for toilets, cement, special tools such as brushes, etc.

First, brush the waterproof coating for the first time. Before construction, it is better to clean the bathroom a little. A dry and clean environment is a key factor in the waterproofing of the bathroom.

When painting, the brushing height is the same. Refer to the thickness standards of the product tracks, fill all the corners of the bathroom, check for any omissions, check that the base layer is firm and if there are cracks, bubbles or peeling.

Then brush the waterproof coating a second time, and after completing the previous step, don't rush to the next step, let it dry for a while and wait for the paint to dry. After that, clean the bathroom, carefully clean the surface of the floating dust, repair the cement mass, loosen the base layer; For some hollow locations such as pipe roots, drainage holes, yin and yang corners, walls and water repair problems, repair these areas, in this small series, I remind you that the yin and yang corners should be painted in a circular arc. Before performing the second step of the waterproofing structure of the bathroom, it is better to use cement mortar to level the ground.

As a result, the waterproofing effect is weakened because the coating is not thick or uniform enough.

The protective layer is also an essential part of the waterproofing of the bathroom to prevent subsequent operations from damaging the waterproofing layer. The protective layer should be completely covered with a waterproof layer and should not be missed to ensure a tight bond with the base layer. Since the water consumption of the restroom is very large, the various pipes are also very dense.

Therefore, once a place is not covered, it may lead to insufficient overall waterproof structure. Therefore, it is especially prudent to ensure that workers are in a protective layer for certain corners. At that time, all the reports were in place.

Closed water testing is the final step in verifying the success of a bathroom's waterproofing structure. When operating, the water level at the grounding point should be at least 2 cm higher than the water temperature for 24 hours. If there is no penetration during this period, the water resistance is very good.

Success, otherwise it means failure and needs to be patched again.

The above isToilet waterproofing measuresProfessional construction methods and steps, I hope everyone can take every detail seriously and meticulously to ensure that the waterproofing is correct and effective.

Bathroom waterproofing project is the top priority of home decoration, because the bathroom needs to be in contact with water every day, and then this site will share with you how to do bathroom waterproofing and waterproof construction precautions.

1. How to do waterproof in the bathroom.

1. Clean the ground, the mason finds the slope, the floor drain should be the lowest place in the whole bathroom, the slope should be as large as possible, the drainage is fast in use, and the groove needs to be left at the pipe groove.

2. The ground needs to be cleaned first. The water around the sewer pipe should be treated without leakage, and the pipe groove needs to be plastered and closed (the pipe and the edges and corners are the most likely places to seep water, so be sure to pay attention to it).

3. Make polypropylene cloth on the ground, and then brush the flexible waterproof coating, and do rigid waterproof painting on the wall, pay attention to the fact that the wall and the ground are not the same, and the wall can not be brushed with flexible waterproofing, and the door should be set up at the same time to block the water (the wall can not have trachoma, loose, if there is one, the wall must be treated, and the grassroots cousin needs to be smooth, smooth and firm) Note: The waterproof coating should be painted at least twice, and the second time can be painted after the first time is dry, and the interval between the two brushes is about 2 3 hours.

4. Waterproof and closed water for 48 hours, and the water surface should be fully soaked to the root and corners of the wall (closed water height 3-5cm).

After an hour, go down to check the waterproof situation (if there is a leakage, you need to check the specific leakage, find out the waterproof is not done well, and do it again).

6. Release the water that leaks from the test and carry out a slope test (the water in all parts of the bathroom can leak to the floor as the standard, and the speed is based on the actual situation).

7. The external water of the floor tiles does not leak and the sand and lime layer is closed.

8. The stone lime paving through the door prevents the water from overflowing again.

9. After passing the waterproof inspection, use ceramsite to mix cement (proportion cement 1: sand 3: ceramsite: 8) for backfilling, find the code flat layer with steel wire mesh reinforcement treatment, backfill should be sloped to the secondary drainage pipe, and if anyone flows down from the brick joints in the future, it can be discharged in time.

10. This step of waterproofing has basically been done, you can paste the bricks, pay attention to the macro words of the floor drain when sticking the bricks, you need to do a certain slope, so that the water can flow smoothly in, and the two sides of the bathroom door cover are also wild, which is coated with about 30cm waterproof coating, which can avoid a certain degree of regurgitation.

2. Precautions for waterproof construction.

1. Each waterproof construction needs to be painted twice, and it is a vertical cross painting, that is, the first painting is painted in the upper and lower directions, and the second time needs to be painted in the left and right directions.

2. The interval between two times of waterproofing needs to be about 1-3 hours according to the different conditions of weather and temperature.

3. When painting waterproof coatings, it should be noted that the direction of painting should be consistent, and overlapping brushing should be carried out to ensure that there will be no gaps when brushing, and the thickness of the brushing is about 1mm.

4. Compared with the first waterproofing, the second waterproofing is more important, so we must pay attention to the construction details of the second waterproofing.

The bathroom waterproof project should do a good job of each waterproof test and pay attention to the construction details. If you have a need for waterproof decoration of the bathroom, you can refer to the above content.

The bathroom was very watery, very damp, very damp. In order to avoid leaks from later bathrooms or water seeping into the building, bathrooms must be decorated with waterproofing. So let's understand the waterproof methods and precautions of toilet engineering, which is a detailed introduction.

Toilet engineering waterproofing method 1Before waterproofing the bathroom, the bottom of the cement mortar should be drained, and the surface should be flat. It is important to note that the slope near the door is small, and the slope around the floor drain pipe is large.

2.When the toilet is impermeable, the bottom drain pipe and pipe root should be strengthened waterproofing, and the pipe root sealant should be sealed. After the floor cement is softened, wipe off the waterproof paint. In this case, attach a glass cloth (1-2 layers) to strengthen the waterproofness.

3.Wait until the walls are clean. There are no small particles and ashes to rust. Wipe down small corners or slopes where walls and floors meet. When adding a water repellent agent, add a glass cloth to enhance the water resistance.

4.If polyurethane waterproofing paint is used, the waterproofing layer cannot be determined according to the number of times, and the thickness should be at least millimeters. In addition, the reinforcing layer of the corners and reinforcing rods must first be brushed, then dried after 4 hours, and then applied to a large area.

When scratched, it should not be scratched and there are no bubbles. Wait 24 hours for curing before applying the next layer.

5.When the bathroom is waterproof, the exterior wall is applied first, and then a flat surface is painted. The direction of the next pass should be perpendicular to the previous direction. When the brush is used at the end, it turns semi-hardened and throws coarse sand, so it is easy to combine with cement mortar.

6.When the waterproof method of bathroom engineering, the waterproof layer should be 300mm from the ground, and the waterproof layer should be 200mm higher than the ground.

7.After the bathroom is waterproofed, a 36-hour waterproof test is carried out as needed.

Toilet engineering waterproof precautions 1Do not scratch.

Before waterproofing the bathroom, use cement mortar to level the floor and waterproof. This prevents the waterproofing coating from seeping into the waterproofing membrane or uneven thickness and leaking walls.

2.Do the important part.

If the waterproofing method of the bathroom project is not enough, it is necessary to pay attention to the intersection of walls, floors, sewers and floors, this place is the most prone to water leakage. Therefore, the waterproofing layer of this place should be strengthened and not dirty.

3.The walls must be waterproof.

When the toilet works the waterproofing method, the floor must be waterproof, and there is a waterproof layer on the walls, and the hail is waterproof at a height of 30 cm from the ground. If there is a bathtub in the bathroom, the adjacent walls must be waterproof and waterproof at a higher height than the bathtub. For showers, the waterproof height should be 180 cm.

4.Perform a waterproof test.

Waterproof bathrooms must be waterproof. At this point, all sewer pipes must be closed and a water injection test must be carried out. After 36 hours, check the walls, floors, and roof of the building for leaks.

The above are the waterproofing methods and precautions for bathroom engineering, especially the corners, which should be cautious.

The first step, before the waterproof treatment of the bathroom, the first thing is to level the floor level of the bathroom, the ground is uneven, when the waterproof paint is painted, it may be uneven, or the ground is easy to crack because of unevenness, which will crack with the ground even if the waterproof paint is applied.

The second step is the height of the waterproof coating. The wall of the bathroom also needs to be waterproofed, generally painted 30cm on the wall from the ground level, which is to prevent the stagnant water from penetrating into the wall to form a resurgence; However, many families will use shower rooms, and in this area, the waterproof paint needs to be painted to 180cm, so that the water from the sprinkler head is not easy to seep into the wall; If it's a bathtub, apply the height to 30 cm above the bathtub.

At the junction between the wall and the ground, including the corner part, as well as the junction between the pipe and the building, these places should use high-elastic flexible waterproof coatings.

Hello, I have seen your question, I am sorting out the answer, please wait a moment 1, before laying bathroom tiles, you must do a good job of wall waterproofing, the height of the general wall waterproof is about 30cm high, if it is a non-load-bearing light wall, you need to do waterproof treatment on the whole wall, at least 60cm high.

2. The choice of bathroom waterproof coating should meet the national standards, for the construction of bathroom waterproof coating, it is very critical to make the joint between the wall and the ground, and we must first do the arc corner, and apply the corners of the wall and the ground in place, so that there will be no water leakage.

After the treatment of the toilet base is completed, the waterproofing of the roll paper coating is taken as an example to introduce the polyurethane waterproofing practice. 1.First of all, the surface of the base layer of the waterproof layer must be painted, and the debris on it must be cleaned up.

2.Then the waterproof material is painted, and the wall must be kept flat when painting. 3.

Finally, carefully paint the floor drain and window cracks of the bathroom, and wait for the waterproof layer to dry.

How to do waterproofing in the bathroom1. We should observe the water circuit of the toilet and transform it in combination with the actual situation, and have a detailed understanding of the concealed project. After the plan is determined, the water, electricity and heating pipes are laid and chiseled. Secondly, in the base treatment, the original decorative materials should be cleaned before the waterproofing project of the bathroom, and then the several sides are paved with cement slurry, and then the waterproof treatment is carried out.

2. When making the waterproof layer, you should pay attention to whether the waterproof coating is evenly painted, the thickness of the waterproof layer should be above, and pay attention to the waterproof treatment of the dead corners and seams. After the completion of the construction, a 24-hour water shielding test should be carried out: all the sewers in the bathroom should be blocked, a 25cm height barrier should be built at the door, and then 20cm height water should be injected.

3. After 5-7 days of waterproof test, after the waterproof coating has formed a waterproof membrane, a layer of cement mortar protective layer should be made on the waterproof coating layer. This can effectively protect the waterproof coating, and the second is convenient for tiles, and at the same time, it can play a good role in the leakage and waterproof pressure of the pipe. The final process is the laying of walls and floor tiles.
