Which is the best waterproof coating for the bathroom?

Generally, the leakage of water in the bathroom is a problem in the details of the building, and we should pay attention to three places, that is, the floor drain, the corner of the wall, and the pipe root. In addition, if the connection between the bathtub drain and the sewer pipe is not tight, it will easily cause gaps and leakage. So we should choose a coating that is most suitable for bathroom decoration, so what waterproof coating is best for the bathroom?

Let's talk about it here!

What waterproofing paint is best for bathrooms.

Waterproof coatingWe should choose a single-component environmentally friendly polyurethane coating, which is currently highly recommended by the Ministry of Construction as a waterproof material. Because this coating can tightly wrap the pipe and the ground, penetrate the gaps, and will not shrink after drying, it is more suitable for small areas of houses with many pipes and gaps than rigid materials such as waterproof cement. Therefore, customers should choose brand coatings when buying this kind of paint, and the material cost per square meter is about 50 60 yuan.

It is understood that at present, some domestic brand polyurethane coating manufacturers have their own construction team, and the public can purchase coatings at the same time, requiring manufacturers to provide professional staff. In order to make the waterproofing period longer in the future, the paint generally needs to be brushed three times, so in order to make the paint fully dry, it is not possible to choose to do it in rainy or wet weather. Generally, the drying period of one-component environmentally friendly polyurethane coatings is about 3 to 4 days.

Counting the one-component environmentally friendly polyurethane coating, the cement layer covered by the coating and the face brick, the material per square meter generally does not exceed 400 yuan. In this way, a bathroom with a size of 5 square meters will cost about 2,000 yuan to redo the waterproofing, and the bathroom measures such as bathtubs that need to be reconfigured are counted separately.

After the waterproofing construction is completed, all the sewers in the bathroom should be blocked, and a line should be built at the door of the bathroom"Low wall"The irrigation test was carried out, and the irrigation height was about 20cm. 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.

At the same time, the wall should also be waterproof. 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 waterproofed at a higher height than the top edge of the bathtub.

In this way, nothing is lost.

The general bathroom leakage water is the details of the building problems, the most prone to problems in three places, we should pay attention to the three places are floor drains, wall corners, pipe roots, these three places due to more interfaces, easy to appear gaps, so easy to leak water. In addition, if the connection between the bathtub drain and the sewer pipe is not tight, it will be easy to create gaps and leakage. Therefore, we should choose a coating that is most suitable for bathroom decoration, and we should choose Langkaiqi flexible-acrylic modified waterproof coating for waterproof coating.

Because this material can tightly wrap the pipe and the ground, penetrate into the gaps, and will not shrink after drying, it is more suitable for small areas of houses with many pipes and gaps such as bathrooms than rigid materials such as waterproof cement. Therefore, customers should choose Longkeqi brand coatings when buying this kind of paint.

After the waterproofing construction is completed, all the sewers in the bathroom should be blocked, and a "low wall" should be built at the door of the bathroom for water injection test, and the water injection height should be about 500px. 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.

At the same time, the wall should also be waterproof. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed about 750px high to prevent water from penetrating the wall. The wall adjacent to the bathtub should also be waterproofed at a higher height than the top edge of the bathtub.

In this way, nothing is lost.

Different places have different requirements for waterproof performance or construction. It is recommended to do waterproof paint with waterproof coating now, the construction is convenient, and the effect is good, the following are the most commonly used waterproof coatings, I hope it will help you: JS waterproof is a polymer cement-based waterproof coating, which is characterized by 1

Excellent flexibility to resist slight vibrations of buildings and micro-cracks caused by various reasons. 2.Excellent waterproof performance, can be used for waterproofing on the front and back surface.

3.It can be applied on a wet base surface and has good weather resistance and aging resistance. 4.

Non-toxic, harmless, environmentally friendly products. Main scope of application: A

Substrates made of concrete, brick masonry, precast, and lightweight bricks. B.Walls, floors or roofs of buildings, such as tunnels, bridges, basements, kitchens and bathrooms, balconies, swimming pools, cisterns, etc.

C.Structures with slight vibrations and cracks, such as around the nozzle, post-pouring belt interfaces, etc. My own home decoration is the waterproof material of Century Flood Rain, it has been 3 years, and no water leakage has been found so far.

Outstanding polymer cement waterproofing coatings, which have been exposed to before, can be trusted.

As we all know, bathroom waterproofing is a hidden project, which is very important in decoration, because the quality of bathroom waterproof materials will affect the use time of the bathroom, when the bathroom is soaked in water for a long time, it will cause the bathroom to be damp and even corroded! Therefore, the waterproof material of the bathroom must be well selected. Let's find out together.

1. Cement slurry toilet waterproof material is a kind of waterproof emerging material, its price is reasonable, waterproof effect is good, is a very popular bathroom waterproof material. However, when choosing, it is necessary to pay attention to the solidity of sand and ash; 2. The acrylic toilet waterproof material is colorless and odorless, and the waterproof purpose is achieved through the conjunctiva of the material. It is very malleable and resilient.

It is also a good waterproof material for toilets. However, the cost of this type of material is high, so the choice should be cautious; 3. The polymer polymer toilet waterproof material also has good ductility and elasticity, and does not have any color and taste, which is very environmentally friendly and healthy. But it also has a disadvantage, it can't collide with anything, otherwise it will cause the waterproof membrane to break and leak.

The price of waterproofing materials for this type of toilet is higher. 4.Polyurethane waterproof coating:

It is mainly liquid, and it is divided into two types: tar type and non-tar type. Non-tar paint is one of the most commonly used toilet waterproofing materials on the market today. It is a curing agent with non-tar substances, such as a curing agent composed of asphalt, additives and fillers.

This kind of toilet waterproof coating is divided into two groups, group A is the curing agent, and group B is the main component of the material. This material has stable quality, low pollution, good aging resistance, good adhesion and water enhancement. Generally, the above four waterproof coatings are used more now, and when we choose, it is best to choose the right waterproof coating according to our own needs.

We must pay attention to the bathroom is the focus of home decoration, bathroom waterproofing work is the top priority of bathroom decoration, the basic waterproofing is not good, the rest are in vain, it is best to choose a better brand coating, I hope my help to you.

There are two kinds of waterproofing, one is hard waterproofing and the other is flexible waterproofing.

Generally, hard waterproof, that is, polypropylene cloth, is used, but the flatness of the base layer is required to be high, and there will be no water leakage if it is done.

Flexible waterproofing is anionic waterproofing, which does not have high requirements for the base layer, and has stronger adhesion under damp conditions, but the cost and cycle are slightly longer.

1: Do a good job in hydropower infrastructure projects.

From a safety point of view, it is better to go up the bathroom water pipes and wires than to go down. However, many "guerrillas" are greedy for labor-saving, and water and electricity go to the ground, and even dig grooves and round holes in the bathroom.

2: Clean the base and walls.

The house is decorated with waterproof, involving a balcony, a kitchen, a bathroom, but the focus is on the bathroom. First of all, use a small metal hammer to knock on the wall and ground, if you find a "poof" empty sound, it means that there is a hollow drum inside, and you must knock out all the hollow drum parts. Then carefully clean the four wall base layers and the floor, pull out the nails, clean up the miscellaneous garbage, rinse it with clean water, and then let it dry.

3: Do a good job of rigid waterproofing.

All kinds of sewer pipes in the bathroom can not be changed, try not to change them; In case of change, you must not use cement mortar to fill the pores, and you must plug the leakage king to fill it three times.

4: Do the second level of elastic waterproof coating.

After a long time in the new house, the hard plugging king elastic coating will be cracked alive due to settlement, thus losing the waterproof effect. Therefore, it is necessary to add a second insurance - elastic waterproofing coatings.

1. Try not to damage the original waterproof layer.

In the newly delivered high-rise building, the waterproof layer is usually made in accordance with the relevant standards, but in the process of decoration, some bathroom bathing equipment and a variety of water and water pipelines may be re-planned, and then the original waterproof layer of the building may be damaged. Qinglong Construction recommends that friends who need decoration should try not to damage the original waterproof layer, and if it is damaged, it must be repaired in time to avoid leakage in the future.

2. Re-paving floor tiles should be waterproof on the ground.

If you need to replace the original floor tiles in the bathroom, after chiseling off the original floor tiles, you must first level the ground with cement mortar, and then do waterproof treatment, so as to avoid leakage caused by uneven thickness of the waterproof coating.

3. The wall must be waterproof.

Water will splash on the nearby wall when bathing in the bathroom, and if you don't do waterproofing, the wall will be prone to mildew, so you must do a good job of waterproofing the wall before laying wall tiles. Qinglong construction suggests that the wall should not be less than 30 cm when waterproofing, and if the load-bearing light wall is right, the entire wall should be waterproofed.

4. The grooves of the water pipes in the wall should also be waterproof.

During the construction process, when pipes, floor drains, etc. pass through the floor slab, it is necessary to carefully construct the waterproof layer around the hole. Buried water pipes in the wall, so as to achieve reasonable planning, lay water pipes are all made larger than the diameter of the groove, the groove is plastered smoothly, and then the groove is brushed with polyurethane waterproof coating.
