How to do waterproofing in the renovated bathroom? How can I avoid a leak in my bathroom?

When doing waterproofing, it is necessary to gently pour a layer of water in front of it to keep it wet and dry, and then apply the flat mortar, and wait until the waterproof coating is dry and then do waterproofing; Ground waterproofing and wall waterproofing should be done, try not to damage the waterproof layer, water pipe grooves should also be waterproof, try to choose better quality waterproof materials.

Windows must be set up in the bathroom, and waterproof tiles must be selected in the bathroom, and waterproof materials should also be selected on the wall; It is necessary to open the windows frequently for ventilation, and it is also necessary to do a good job of separating dry and wet in the bathroom, so that there will be no water leakage.

When decorating, a waterproof layer should be done to prevent water leakage; If there is a leak in the bathroom, first check the cause of the leakage, or ask the decoration worker to check and fill the gap.

It is more important to do waterproofing, it is better to do waterproofing directly, and you must pay attention to the material to avoid leakage in the bathroom, such as leveling mortar.

Some homes have water seepage, mostly because key areas are not waterproofed. So how can you do a good job of waterproofing? The old owner has been decorating for 30 years, the toilet is waterproof, and I am no longer afraid of leakage.

In addition to buying *** waterproof paint, we should also apply it evenly and carefully during the construction process, leaving no gaps. In addition, the area to be painted is also important. For example, in the rainy area, we need to achieve the height of meters, and the other walls should be at the height of meters.

And the sink is a meter higher than the tabletop to prevent splashing on the wall and seeping water. At the same time, it is also necessary to pay attention to waterproofing, not only the inside of the bathroom, but also the area of the door and the inside and outside of the door cover. In this way, moisture can be effectively prevented from entering the corridor.

It is best to choose a flexible waterproof coating, because the waterproof membrane formed in this way has a certain elastic function and can protect the corners that are easily damaged. In addition to installing an open floor drain on the floor, it is best to make a dark floor drain in the caisson of the bathroom. The open floor drain is to drain the ground water faster, and the dark floor drain can ensure that the seepage water under the ground can be discharged, so that there will be no water accumulation in the caisson.

The way we lay the tiles also affects the waterproofing layer. Generally speaking, the way of floor tiles and wall tiles is not suitable for the bathroom. In this way, the wall tiles will fall directly on the ground, which is easy to damage the waterproof layer.

should be made into wall tiles pressed floor tiles. It can not only protect the waterproof layer, but also effectively prevent the stagnant water from seeping into the ground. When there is standing water under the tiles, this type of pavement cannot block the standing water and can damp the walls around the hallway.

Therefore, it is best to make a water retaining pier under the threshold stone during construction. This effectively prevents the water under the tiles from spreading outward.

The yin and yang angles should be made arc or obtuse angles. When applying waterproof coatings, the surface must be dry and smooth, without unevenness, hollowing, cracking and other undesirable conditions. Finally, it is best to treat floor drains, pipe roots, and drains with rounded corners, and remember to be firm.

Like walls and floors, joints, and even the joints between water pipes and floors, these are the most overlooked places, so be sure to pay attention when applying waterproof paints. Remember to do a good job of cement mulch work for bathroom plumbing pipes, brush a 10 500px waterproof paint from the ground up, and then redo the waterproofing on the ground, combined with the original waterproof layer to form a composite waterproof layer to increase the waterproof performance.

Once the waterproofing work is complete, seal the doors and outlets, store the water on the bathroom floor, and mark it. After 24 hours, observe the lower liquid level again. If there is no significant drop, it proves that there is no leakage.

A lot of white people can't get their hands on waterproofing paint when it comes to buying it. In fact, they should look at the packaging first. See whether the product packaging color is bright, whether the handwriting is clear, and whether the manufacturer and certificate are complete.

Use your nose to smell the pungent smell of waterproof paint. Once the toxic waterproof coating is used, there will be a long-term process of releasing toxic gases in your home, so special attention should be paid to it.

Buy better waterproof materials, generally in the bathroom, at least brush more than twice, usually actively check whether the leakage in the bathroom is blocked by hair or other debris.

Then it is necessary to use special waterproof materials, and the bathroom should be tested for water leakage.

When decorating the bathroom, it is very important to make a waterproof compartment under the tile, including the wall, and the second is to choose the kind of waterproof tile. The way to avoid leaking water in the bathroom is to make a sewer outlet.

Generally, developers will do a layer of waterproofing first, and then you can do another layer yourself, mainly because the floor tiles in the bathroom are more sloped, and basically there will be no water leakage.

1. Ground leveling: If you want to do a good job of waterproofing the bathroom, you must first level the ground of the bathroom. So if your home is an old house and you want to renovate the bathroom, you need to knock out all the old tiles, and then chisel the cement under the old tiles, and polish the ground flat.

Then it is paved with cement mortar, some basic ground leveling is done, and then waterproof paint is painted. The waterproof coating needs to be brushed about 2 or 3 times, only a thin layer is needed, not the thicker the better, remember to brush the seams several times, these are the places that are most prone to water seepage.

2. Wall treatment: The wall waterproofing treatment of the bathroom is also very important. Because the wall is not waterproof, the subsequent wall seepage will also affect the furniture on the other side of the wall, so it is recommended that the bathroom wall waterproof should be about 30 cm.

In addition, it is recommended to carry out detailed waterproofing measures in the shower room area, and it is best to achieve a height of meters in this area to prevent water seepage caused by long-term showering.

3. Closed water test: After the waterproofing of the bathroom is done, there is another step that must be done, that is, the closed water test of waterproofing. Then, the closed water test is to block all the drains in the bathroom first, and then build a 25 cm high "barrier" at the door, and then pour water into the bathroom, the height of the water is about 20 cm.

After 24 hours of observation, if there is no water seepage, it means that the waterproofing is done well, and the next step of construction can be carried out.

Waterproofing the bathroom is a top priority. Many families complain about leaky bathrooms. The reason is that the waterproofing is not done well.

If the bathroom is not waterproofed well, it will not only cause a lot of trouble to yourself, but also affect the neighbor next door. Basic treatment must be for all waste, including dust on the floor and walls. The surface should be polished or shoveled.

The yin and yang angles should be made into arcs or obtuse angles.

When applying waterproof coatings, the surface must be dry and smooth, and there must be no undesirable phenomena such as unevenness, hollowing, and cracking. Finally, such as floor drains, pipe roots, and drains, it is best to deal with fillet and remember to be firm. After the completion of the waterproof coating, a water storage test should be carried out immediately.

Pour the water into the bathroom, wait 24-48 hours to see if there is a leak, and then carry out a concealed inspection and acceptance. A waterproof protective layer should be made. Generally, 15mm 20mm thick cement mortar or 30mm 50mm concrete is used, which can be pasted after drying.

The bathroom should be waterproof to a height of 1800 mm. If there is a large bathtub, the height should be controlled at 300 mm. Waterproofing of bathroom walls is also very important.

Since the walls are not waterproof, subsequent wall leaks can also affect furniture on the other side of the wall. Therefore, it is recommended that the wall of the bathroom be waterproof about 30cm. Detailed waterproofing measures are taken in the shower area, preferably at the highest height, to prevent water seepage caused by long-term showering.

The decoration team made cement mulch for the upper and lower water pipes of the bathroom, and then redid the waterproofing of the ground, and added the original waterproof layer to form a composite waterproof layer to enhance the waterproofness.

Fill the bucket with water, then fill the floor drain and toilet drain to see if the water can flow away quickly. If the water is slow or the water can't slide out, it means that the sewer pipe is clogged and needs to be repaired. Discharge water directly to the ground, stop after a period of time, and then observe the surface water flow.

See if there is any water storage in the local area, or if the water can flow out smoothly through the floor drain, so that we can judge whether our ground slope is acceptable.

The first step is to clean up the grassroots.

Many bricklayers do not pay attention to this item, but in fact, a good base layer is very important for waterproof construction. When cleaning the surface, the master not only removed the dust and impurities on the surface, but also leveled the depressions and unevenness.

The second step is to brush the leaky parts with waterproofing.

Water leaks in the bathroom tend to be found in walls, corners or drain edges. The master said that before doing formal waterproofing, it is necessary to use waterproof paint to waterproof these places. This can make the areas that are prone to leakage more waterproof, and avoid hidden dangers in the future.

The third step is to do the formal waterproofing.

This is the most critical step. Not only should the waterproof paint be evenly applied to the floor, but also the distance between 30 cm and 50 cm should be returned to the surrounding walls. In addition, the shower area should also be waterproof at least one meter and eight high.

Special attention should be paid to the connection between the wall and the ground must be evenly and slowly painted, without leaving the slightest gap.

The fourth step is the maintenance of the waterproof layer.

After the waterproof coating is painted, it should be kept for a period of time, so that the paint is fully bonded to the base layer, so that the waterproof effect will be better.

The fifth step is the closed water experiment.

Generally, after the waterproof layer is dry, the closed water test should be carried out. Usually 24 hours is fine, but sometimes the leak problem takes a day or two, so it is best to do it for 48 to 72 hours. And after the experiment is completed, be sure to check the roof downstairs to see if there are any clues of water seepage.

In addition, if it is a sunken bathroom, you must pay attention to the waterproofing before backfilling, which is much more important than the waterproof layer on the ground. If this is done well, there will be no leakage even if the waterproofing layer on top is not so perfect.

The bathroom wall should be waterproof and not leaky, first of all, it should be separated from dry and wet, and when decorating, it is necessary to carry out waterproof and moisture-proof work and measures.

When decorating the bathroom, be sure to polish the ground to ensure that it is in a smooth and flat state, after laying the mortar, be sure to apply 2 or 3 times of waterproof materials, and to apply a few more layers in the corners and gaps, to achieve a waterproof layer of about 30 cm, so that it can not leak. Waterproof materials can be used by doing a good job of waterproof measures during decoration.

Be sure to carry out waterproof treatment, waterproof coating should be brushed at least three times, the laying of sewer pipes must be reasonable, we must pay attention to the selection of tiles, pay attention to the laying of tiles, in order to better waterproof.

When decorating, the ground should be sliding, so that it can become particularly flat, you can use cement mortar, it is best to do three times waterproof height should choose 30 cm.

It should be done three times when doing waterproofing, and some cement mortar should be used when doing waterproofing, so that there will be no very serious water leakage problems.
