How to waterproof the bathroom wall? What are the precautions?

First, the slope is found in the direction of the floor drain, and then bean stone concrete or cement mortar is used to ensure a smooth surface. The specific situation of wall waterproofing was analyzed. Generally speaking, the slope of the floor drain is large, and the slope of the doorway is small.

For places where the pipes pass through the root of the floor, the waterproofing strength should be greater. After the cement is smooth, it can be coated with waterproof coating, generally close to 1 to 2 layers of glass wire cloth reinforcement layer. Where there is a slope at the junction of the wall, it should be strengthened when brushing waterproof coating, about 1-2 layers.

The requirement for the total thickness of the polyurethane waterproof coating is more than millimeters.

When painting, the square meter should be brushed inside and behind, and the next brush can be safely perpendicular to the direction of the previous brush. If there is a riser, it should be waterproof first before making a riser. After that, when brushing, throw coarse grit grains.

If you want to replace the bathroom floor tiles, you need to cut the original tiles, you must use cement mortar ground leveling, and then do waterproof treatment to avoid leakage caused by uneven thickness of waterproof coating.

The most difficult place to clean in the bathroom is the seam, which is also the most problematic. If you do waterproof construction, remember to supervise the renovation workers to deal with these corners, and the application of waterproof paint must be in place. The wall treatment is also very important Waterproofing is not only the ground, the wall also needs to do a waterproofing step, about 30 cm of waterproof paint to prevent water from seeping into the wall.

But if the walls of the bathroom are non-load-bearing, lightweight walls, you need to apply waterproof paint to the entire wall. After the waterproofing is done, to make a waterproof toilet for the bathroom, you can install 20 cm of water in the bathroom, and wait until a day later, and then check whether the floor and wall of the bathroom will penetrate, and the waterproof experiment is the best way to verify the waterproof project. According to the normal construction, the bathroom is generally waterproof twice.

The following are the specific construction steps of waterproofing the bathroom.

Before the waterproof construction of the bathroom, the floating ash on the wall and the floating ash on the ground should be cleaned. However, be careful to block the toilet nozzle to avoid debris falling into the pipe. For the waterproof construction of the bathroom wall, the excavation of the wall pipe should be filled with cement first, and the ground should also be leveled

The treated ground should first be waterproof to ensure that the pipe roots do not leak. When brushing the second waterproof work, it is necessary to ensure that the waterproof is dry before brushing, otherwise it will not play a reinforcing role. The correct way to waterproof the layer is to lay a cement slurry protective layer on the waterproof layer to protect the waterproofing from being damaged by the backfill construction.

On the one hand, the slope of the toilet must be calculated accurately, to ensure that the water in the bathroom can be discharged through the sewer, and secondly, some pipeline treatment work should be carried out waterproofing, waterproofing in this regard must be very careful, waterproof paint should be painted, and the protective layer should be reinforced, and secondly, in the corner of the bathroom wall, it is necessary to ensure that the surface is smooth and brush several layers of waterproof coating.

Prepare some environmentally friendly materials, prepare some waterproof materials, prepare moisture-proof materials, choose experienced workers, and choose the right team; When doing waterproofing work for the wall of the bathroom, be sure to use environmentally friendly materials, use waterproof materials, avoid defects, and do the work in place, there will be no rework, and there will be no water seepage.

The waterproofing of the wall of our bathroom is a layer of waterproof cloth and a layer of waterproof paint. And the floor was made of a tarpaulin, and three more waterproof paints were applied. The waterproof height of the bathroom wall should be a little higher, try to be about 1.5 meters and above.

The renovation of the bathroom is a very complex issue that needs to be done step by step according to the specifications. Waterproofing of bathroom walls is a crucial step, but many friends are not very familiar with the requirements of engineering waterproofing. SoWaterproofing of bathroom wallsHow?

And there isWaterproofing of bathroom walls1. The ground is facing the direction of floor drainage. In the case of ensuring a flat surface, the use of concrete or cement mortar was specifically analyzed. Usually, the slope near the floor drain is large, and the slope near the door is small.

2. When the pipe penetrates the root of the floor, the waterproof force must be greater. After smoothing the cement, a waterproof coating can be applied, usually 1-2 layers close to the glass cloth reinforcement layer.

3. At the intersection of the walls, there are inclined feet, about 1-2 layers when the waterproof coating should be strengthened.

4. The total thickness of the waterproof coating film should be at or greater.

5. When painting, square meters should be painted on the inside, and the next brushing can be perpendicular to the previous brushing direction.

6. When wrapping up the water pipe, it must be waterproof before making the water pipe.

7. When painting for the last time, the coarse sand should be discarded.

1. There are two kinds of waterproof materials on the bathroom wall, and when using polyurethane products, a layer of polyester fabric should be added to the corner of the bathroom. In the method of modified bitumen products with a high polymer content, it is necessary to use polyester fabrics of the reinforcing material of the shell.

2. In the waterproof construction process of the bathroom wall, polymer coating is often used, and the waterproof effect of this material is also very good, so the utilization rate is very high, not only has good ductility and environmental performance, but also has very low quality.

3. There are many new waterproof coatings, and most of the waterproof coatings are two components, so when you use waterproof coatings for bathroom walls, you must know how to mix the paints, once the proportions of the paints are not correct, it will greatly affect the impermeable effect of the paints.

The bathroom is a place we use every day, and we can imagine how important it is to us. The bathroom has a great relationship with water, and waterproofing is a must for the bathroom. Bathroom waterproofing is a concern for most owners, so how to make waterproof on the bathroom wall?

What are the precautions for waterproofing in the bathroom?

1. Leveling the square layer.

When brushing the waterproof coating, it is necessary to ensure that the construction site is clean and dry, and the waterproof paint should be filled, and the ground should be squared with cement mortar (especially for the house that has been renovated), and then waterproofing. This avoids leakage caused by uneven thickness or puncture of the waterproofing membrane. Brush the waterproof paint a second time.

Note that there needs to be a certain time interval between the second waterproof 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.

Second, do a good job in key parts.

The waterproofing of key positions must be done well, for example, the joints between the wall and the ground, and the joints between the water and water pipes and the ground, which are the places where the most tolerant Tong Qiao cover is prone to problems. Therefore, these parts must be paid special attention to, and the treatment must be meticulous, without the slightest sloppiness. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed about 30cm high to prevent water from penetrating the wall.

The wall adjacent to the bathtub should also be waterproof at a height higher than the upper edge of the bathtub, and the shower should reach a height of 180 cm.

3. Lay a protective layer.

When doing waterproofing, remember to put a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off. After the waterproofing construction is completed, all the sewers of the toilet should be blocked and the water injection test should be carried out.

After 24 hours, if there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good. On the contrary, it is necessary to find out the leakage point and carry out repairs.

When decorating a house, waterproofing the bathroom wall is an important step in bathroom decoration. Only if the waterproof effect is good, the bathroom will be more comfortable and convenient during use. So, how to do a good job of waterproofing the bathroom wall?

In fact, as long as you grasp the waterproof height of the bathroom and pay attention to the construction details, you don't need to worry about the owners.

1. How to do a good job in the waterproof height of the bathroom wall.

Except for the shower room, the waterproof height of the wall is not less than 30 cm. This height can effectively reduce the occurrence of moisture on the wall surface, and avoid the problem of hollowing out the porcelain in the later stage. However, if the wall is not a load-bearing structure and the entire wall needs to be waterproof, the construction height should not be less than 180 cm.

If the bathroom has a shower room or shower area, the waterproof height should not be less than meters. If a bathtub is installed, the waterproof height of the wall should exceed the total height of the bathtub by 30cm to avoid water vapor infiltration. In addition, the waterproof structure of the bathroom floor is mostly made of poured reinforced concrete, the waterproof height is generally 2-3 cm, and the floor drain is inclined and smooth.

2. How to do a good job in the precautions of bathroom wall waterproofing.

Before the waterproof construction of the bathroom, we must first clearly understand the layout of the entire hydropower space, and then enter the targeted waterproof construction of Qiqingxing. The ground should be leveled first and then waterproof. After the waterproofing layer is dry, a one-day waterproofing test is required to check the waterproofing effect.

In addition, after a week, the waterproof layer should also be used with resistant cement mortar to improve the waterproofness and facilitate the laying of tiles in the later stage.

In addition, how to do a good job of waterproofing the bathroom wall also includes cleaning the bathroom base layer before waterproofing construction and removing dust, debris and residue that were present in previous construction. The construction surface is smooth and dry, which can effectively avoid the problem of uneven waterproof thickness, which will affect the waterproof effect.

The waterproof construction coating should not be too thick. Many people think that thicker is better, but this is actually a mistake. Most bathrooms have a waterproof structure that needs to be painted two or three times, and the thickness needs to be uniform. The waterproof coating is too thick and easy to crack, reducing the waterproofing effect.

It is not good for the waterproof height of the bathroom to be too high, which will not only cause a waste of waterproof materials, but also easily cause inconvenience in the later installation. The tile is attached to the waterproof layer, which can easily affect the adhesion of the tile, resulting in poor laying, easy emptying and falling off.
