Which material is best for waterproofing in the family bathroom, and how much is it per square meter

Generally, the leakage water in the bathroom is a problem with the detailed structure of the building, and the three places of floor drain, wall corner, and pipe root are prone to gaps due to more interfaces, so these three places are generally more prone to leakage. In addition, if the connection between the bathtub drain and the sewer pipe is not tight, it is easy to create gaps and leakage.

The waterproof material should choose a one-component environmentally friendly polyurethane coating, which is currently recommended by the Ministry of Construction. Because the paint 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 than rigid materials such as waterproof cement. When buying this kind of paint, you should choose brand paint, and the cost of materials 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 professionals.

In order to make the waterproofing period longer in the future, the paint generally needs to be brushed 3 times, so in order to make the paint dry enough, it is not possible to choose to do it in a rainy or humid climate. 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 on the coating and the surface 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 re-do the waterproofing, and the bathroom facilities such as bathtubs that need to be reconfigured are calculated separately.

After the waterproof construction is completed, all the sewers of 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 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.

The walls should also be waterproofed. 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.

A milky white environmentally friendly synthetic polymer waterproof coating. The composition of the waterproof coating by weight: SEBS 4-8 parts, SBS 5-14 parts, coumaron resin 2-8 parts, petroleum resin 4-14 parts, terpene resin 2-12 parts, p-tert-butylphenol formaldehyde resin 1-5 parts, poly-methyl styrene 1-6 parts, mica powder 1-10 parts, rutile titanium dioxide 1-5 parts, antioxidant 264 parts, antioxidant 1076 parts, antioxidant SP parts, defoamer parts, fragrance parts, ultraviolet absorber parts, cyclohexane 5-15 parts, 1-5 parts xylene, 5-30 parts of 200 solvent oil, 4-15 parts of 120 solvent oil.

The material has good comprehensive mechanical properties, strong waterproof performance, convenient construction, environmental protection and pollution-free.

Now the bathroom and kitchen are used in the third generation of green waterproof coatings, Wan Shibo long-term waterproof experts, its waterproof performance is superior, and the structure has the same life!

Waterproof coatings.

One square is about 30 yuan.

Don't look at those useless waterproofing This piece must be good for your own home use The domestic one is still the best Dongfang Yuhong The amount of waterproof is small, but if you don't use it well, you will be hurt with a first-line brand.

It's better to do a rigid one, like silicone, and then a flexible one, like polyurethane.
