Which waterproof coating works well for the bathroom

The well-known waterproof coating brand has Aili, which is an imported product from the United States, which has no peculiar smell and can effectively remove the peculiar smell in the bathroom, antibacterial and mildew-proof, so that the interior can be kept bright and white for a long time. Because there are many water stains in the bathroom, and the air is not well dredged and humid, you can make a mortar waterproofing agent protective layer to increase the strength of the wall and improve the puncture resistance.

Do waterproofing needs to be done on the surface of the water, dig excellent permeability crystalline waterproofing, you can do it yourself on the cement surface with a super permeable waterproof guard (if there are cracks and potholes on the cement surface, fill the complete with metin porcelain glue and then do waterproofing).

For the tile surface, first check whether the filling of the tile gap is complete (if the filling of the tile gap is incomplete, fill it with Meiding porcelain glue, and then use a stone tile waterproof guard to do waterproofing).

Exterior wall paint can be made waterproof with transparent waterproof repair adhesive.

The product will penetrate into the base layer and make the base layer waterproof. The product is recommended to be constructed in a dry place, the drier the base surface, the deeper the product can penetrate, if the base surface is full of moisture, high density, the material can not penetrate well. Regarding the principle of waterproof plugging, the source of water leakage is not blocked, and the water will only continue to penetrate into the wall, which will exist inside the wall for a long time, and will leak out from other parts of the wall when the water reaches a certain level.

The problem cannot be solved, and only by spraying waterproofing agent on the outside of the roof or exterior wall so that the water cannot penetrate into the wall and flow away can the problem be completely solved.

LM composite waterproofing paint or JS waterproofing paint can be used.

Compared with other functional areas in the home, the bathroom is the most damp place, so the waterproofing project must be done well. So, which waterproof material is better? 1. Polyurethane waterproof coatings:

Polyurethane waterproof coating is the most common type of waterproof coating on the market, which is a one-component polyurethane waterproof coating made of isocyanate-containing prepolymer formed by addition polymerization reaction of isocyanate and polyether, and mixed with various additives. There are several common types of paints. 2. One-component polyurethane waterproof coating:

The waterproof coating is a reactive flexible waterproof coating, which has good physical properties, strong adhesion, and curing at room temperature and humidity. 3. Non-tar polyurethane waterproof coating: The waterproof coating is a two-component material, using water as the chain extender, which avoids the toxicity of the amine chain extender, and forms a rubber waterproof layer with elasticity and no joints after curing.

4. Acrylic waterproof coating: The waterproof coating is made of pure acrylate copolymer or pure propionate emulsion, adding an appropriate amount of high-quality fillers and additives, and is a synthetic resin one-component waterproof coating. 5. JS composite waterproof material:

This waterproof coating is a waterproof coating composed of organic liquid material and inorganic powder, which is a waterproof material that has the advantages of high elasticity of organic materials and good durability of inorganic materials. It is a new type of waterproof material developed after absorbing foreign advanced technology. 6. Cement-based permeable crystalline waterproof material:

The waterproof coating is a waterproof material composed of Portland cement, quartz sand, special active chemicals, etc. Thanks to the strong permeability of water, chemical reactions and water and leak resistance are realized. 7. Polymer cement-based waterproof coating:

Polymer cement-based waterproof coating is the general name of some waterproof coatings, the main material is some polymer emulsion, only these polymer polymers can not be made into the waterproof coating we need, therefore, some matching materials are also added to it. So it's a two-component composite waterproofing coating. In addition to having super waterproof performance, the paint film also has good flexibility and weather resistance, and the most important thing is that this paint is not flammable and does not have any corrosiveness, which will not cause any harm to the construction personnel.

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.

High-performance mortar waterproofing agent, two-component polymer modified cement-based waterproofing mortar (K11 general-purpose type), two-component polymer modified cement-based waterproof coating (K11 flexible type), ground wall solid, Wangu brand super waterproof (composite dual-purpose) and so on.

Toilet waterproofing practices:

1. Ground treatment.

Be sure to level the ground before applying waterproofing. Screed construction method: if there are voids, cracks and unequal defects on the base surface, repair and smooth with cement mortar.

The base surface must be firm, flat, clean, free of dust, greasy, wax, release agent, etc., and other debris substances. The construction of the waterproof layer can only be carried out after the screed is dry, and the construction should be fireproof and waterproof during the construction. After the waterproof layer is completed, the finished product should be protected, and no one should walk around.

2. Wall treatment.

About 300mm high waterproof paint should be used for wall treatment to prevent water from penetrating the wall and returning moisture.

The painting height between the wall and the floor (plane and façade) of the bathroom should be greater than 100mm.

If there is a shower in the bathroom, the waterproof height of the room is not less than 1800mm.

If there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 300mm higher than the bathtub.

The waterproof height of the bathtub is not less than 800mm.

The waterproof height of the squatting pit should exceed the ground of the squatting platform by 400mm.

For the light wall of the bathroom renovation and the self-built light wall, it is recommended that the waterproof height should be at the top.

3. Do a closed water test.

After the waterproofing construction is completed, the water storage test is carried out. Block all the drains in the bathroom, build a water barrier about 200mm high at the door, and then pour about 20mm 30mm deep water into the bathroom, and check whether there is leakage on the surrounding walls and the ground after 24 hours, the waterproof experiment is the key to ensure the quality of the bathroom waterproof project, and it must be done. If there is no leakage after more than 24 hours, it is considered qualified.

If water leakage is found, the water storage test should be stopped immediately, the waterproof layer should be re-improved, and the water storage test should be carried out after the treatment is qualified.

Home decoration kitchen and bathroom waterproofing The best waterproof water material is to use polymer cement-based waterproof paste, that is, the name on the market is: general-purpose, flexible, K11, JS, GS waterproof coating slurry, this kind of product is non-toxic, harmless and pollution-free, simple and fast construction, and cement substrate bonding tightly, long service life, strong waterproof effect, moderate price and other significant characteristics.

Other waterproof materials used in home waterproof decoration have various unsuitables.

Now the home waterproof material industry, that is, the polymer cement-based waterproof coating industry is of top quality and good reputation, and the brands commonly used by families are: JCDecaux, Leibangshi, Oriental Yuhong, Sika, Longma, etc. Their products are all of good quality and there is no big difference.

1.Which is the best waterproof coating? JS Waterproof Coating:

It is a kind of two-component, water-based building waterproof coating made of polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and other polymer emulsions and various additives, and inorganic fillers such as cement, quartz sand, light and heavy calcium carbonate and inorganic powder composed of various additives through reasonable proportioning and compounding.

2.Polyurethane waterproof coating: mainly liquid, 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.

3.Which is the best waterproof coating? K11 Waterproof Coating:

K11 waterproof slurry is a two-component flexible waterproof material, which is a flexible waterproof membrane obtained by mixing special modified polymers with a variety of additives and dry powders, which has good adhesion to the concrete and mortar base surface, and can form a tight and firm waterproof coating with good durability.

4.Cement mortar toilet waterproof coating: the material is a special adhesive (a bit like a special glue) that is mixed with fine cement and sand ash dust.

5.Which is the best waterproof coating? Acrylic toilet waterproof paint:

It is the earliest and largest application in eco-friendly paints and coatings. The biggest feature of this material is that it can be diluted with water to make a water-soluble material, and it is colorless and odorless (lacquer can be mixed with colorants as needed), but it is an unusually dense waterproof material after the conjunctiva.

6.Polymer polymer waterproof coating: The material is mostly made of multi-chain polymer materials derived from rubber sources.

It has good ductility and elasticity. It is colorless and odorless, and has a good environmental protection type. However, the characteristics of his rubber source are that it has great viscosity before drying, and any small bumps and contacts will be damaged by the waterproof film, and the thickness of the brush cannot be brushed, and it is basically transparent after drying, and the visual effect is not good.
