Waterproofing is a very important work in our decoration process. Whether waterproof work is done well or not is inseparable from the choice of waterproof materials. Many owners don't know how to choose waterproof materials, which has become a major problem in decoration. So how to choose a good quality waterproof coating? Let's take a look at what we must know when purchasing waterproof materials. In the process of waterproofing, the selection of waterproof coatings plays a vital role, but many users don't know much about waterproof coatings. So, today Bian Xiao will tell you how to choose a waterproof coating with good quality that suits you. 1, when choosing waterproof materials, we should distinguish between flexibility and rigidity. Many people don't know the difference between rigidity and flexibility when purchasing waterproof coatings, so it is difficult to buy suitable waterproof coatings, which will affect the final waterproof effect. Flexible waterproof materials are formed by chemical reaction to isolate the building structure from the environmental water, thus achieving the purpose of waterproofing. Rigid waterproof materials can improve the impermeability of concrete base by improving its compactness and reducing its porosity. There is no difference between flexible waterproof materials and rigid waterproof materials, but the choice of flexibility or rigidity is determined by different decoration environments. The ductility of flexible waterproof material adapts to slight structural deformation and is more suitable for the reconstruction of old and new houses. Rigid waterproof materials have poor adaptability to deformation, but good hardness and strength, and are generally used to prevent moisture. 2. Choosing different waterproof materials according to different waterproof parts and different spaces has different requirements for the performance of waterproof coatings. Therefore, when selecting waterproof coatings, besides distinguishing flexible and rigid waterproof materials, waterproof coatings should also be selected according to different parts. Only by using the right place can we make the best use of everything and achieve the best waterproof effect. 3. Choose different waterproof coatings according to the geographical location. Geographical location will also have higher requirements for waterproof coatings. It is rainy in the south and snowy in the north. In contrast, in the south, when it rains, the roof is always wet, the drainage is not smooth, and there will even be water accumulation, and it will not be done for several months, and the waterproof layer will be soaked. In cold and snowy areas, some waterproof materials can not withstand the cyclic changes of frost heaving and shrinkage at low temperature, and will age and break in a short time. Therefore, different waterproof materials should be selected for different geographical locations. 4. Choose waterproof coating with environmental certification. When some families do waterproofing, they often mistakenly think that the waterproof area of interior decoration such as bathroom and kitchen is not very large. After using waterproof paint, they will continue to use cement and tiles on it, so whatever waterproof material they choose will not cause pollution. Actually, it is not. Because of the concealment of waterproof layer, once inferior waterproof coating is used, it will pollute the indoor environment for a long time. Therefore, the waterproof coating should be selected through environmental protection certification standards (such as ten ring certification, EC 1 certification, etc.). 5. Look at the product inspection report of waterproof coating. Regular brands of waterproof coatings will have corresponding product testing reports. By reading the product inspection report, we can know the composition and quality of the product at a glance, so as to avoid buying inferior products. 6. Choose waterproof coating according to the use area. The amount of waterproof coating is directly related to the waterproof construction area of the home. Amount of waterproof coating = waterproof construction area * amount of waterproof coating per square meter. When calculating the amount of space, it is necessary to pay special attention to the fact that the waterproof area of the bathroom shower area is 1.8m, and the waterproof height of the non-shower area should be 35cm, so as to avoid waste caused by inexhaustible or inappropriate space.

In the process of home improvement, waterproof decoration, as a concealed project, is a very important part, especially in recent years, there is no choice of waterproof materials, and the leakage phenomenon is obvious, and many neighborhood disputes caused by leakage problems, so now everyone attaches great importance to it in the decoration process. The choice of waterproof coating has also become the most important in the choice of decoration building materials. What kind of waterproof coating is better? How do we choose? First, we should recognize famous brands when purchasing: At present, the market is full of fake and shoddy goods, and toxic substances explicitly eliminated and prohibited by the state also flood into people's homes. Ordinary consumers should choose brand products with high popularity, good reputation, high anti-counterfeiting degree and passed the international quality system certification. 2. Waterproof parts should be comprehensive: bathroom (return height not less than 1.8m or full height), kitchen, balcony (return height not less than 0.3m), all floors and walls of the first floor residence (return height 0.3m), basement floor and walls should be waterproof and moisture-proof. Third, the thickness of the waterproof layer should be sufficient: the thickness of the waterproof layer directly affects its waterproof life. If the thickness of waterproof layer is reduced, its waterproof life will be reduced. Fourth, the construction technology should be meticulous: the joint between the wall and the ground, the corner of yin and yang, the water pipe, the floor drain, the periphery of sanitary ware, and the gouging at the laying place of cold and hot pipes are the key waterproof parts, so the construction must be meticulous. 5. Water-closing experiment after completion: After waterproof construction, close the entrance and drain, store water indoors for 24 hours, and check whether there are any leakage points. Six, such as leakage, must immediately implement remedial measures. The top ten brands of waterproof coatings are: 1 Oriental Yuhong (China well-known trademark, the best waterproof project in China, the first-line brand of family waterproof, Beijing Oriental Yuhong Waterproof Technology Co., Ltd.). Waterproof is the first listed company. 2 Leibangshi (a famous brand in China, who put forward and formulated the concept of family waterproofing, advocated and guided family waterproofing experts, Guangzhou Leibangshi Chemical Building Materials Co., Ltd.) 3 Gaode (founded in 1883, the earliest famous brand in the field of applied chemistry in China) 4 Henkel (starting from 1876, It is a famous brand in the field of applied chemistry in the world) 5)6 Sika (Swiss Sika was founded in 19 10, and is the world's leading supplier of building chemical materials) 7 Ylide (Guangdong Keshun Chemical Co., Ltd., a national high-tech enterprise integrating R&D/ building waterproof materials manufacturing) 8 Ma Bei (the largest building glue manufacturer in the world, Mabeizhuoneng Building Materials Co., Ltd.). Shenzhen famous trademark, Shenzhen Golden Panther Waterproof Material Co., Ltd.) 10 Zhuobao (China not only buys guaranteed waterproof products, but also the quality of waterproof construction is a major reason that affects the waterproof effect of toilets. I hope it helps you! Dear recognition is my greatest motivation!

1. How to estimate the amount of waterproof materials? Waterproof coating dosage = waterproof construction area * coating dosage per square meter. 2. What is the dosage of various waterproof materials per square meter? According to the instructions for the use of various waterproof coatings, the theoretical amount of materials required for coatings with a thickness of 1.5MM is as follows: 1) acrylic acid: 3kg/m2) polyurethane: 2kg/m2) polymer: 3kg/m2) flexible cement mortar: 3kg/m2 (this is the theoretical value. At present, the management of building materials market is not standardized, and there are many fake and shoddy products on the market. When buying, you should choose relatively well-known brands. Real environmentally friendly waterproof materials should have ten ring certification or CTC environmental protection certification and product certificate. In addition, attention should be paid to the service measures of manufacturers when purchasing waterproof coatings. Generally, regular manufacturers will have relatively standardized pre-sales, mid-sales and after-sales services when selling products. 4. Why do you recommend buying materials in the building materials supermarket? Generally, the products in building materials supermarkets are clearly priced and the supply is relatively regular, so the products are not prone to counterfeit and shoddy products, and the problems such as return and exchange are relatively easy to solve. 5. What is the cost performance of various waterproof materials? All kinds of waterproof coatings sold in the market, as long as they meet the national standards, such as Luban waterproof and Qinglong waterproof lamp, should be used as home improvement waterproof. These coatings have their own advantages, and you can choose according to your own needs. Polyurethane waterproof coating has good elasticity and extensibility. In terms of film quality alone, its comprehensive performance is the most outstanding among all kinds of coatings, but the construction period is long and the price is expensive. It is worth noting that most of the brand-name products on the market are not pure polyurethane, and their environmental protection performance is not very good; Acrylic waterproof coating has the advantages of simple construction, environmental protection, good film performance and moderate price. This kind of coating will be used in general home improvement waterproof; JS is a kind of rigid-flexible waterproof coating, which is convenient for construction, environmentally friendly and non-toxic, and also a good choice. Waterproof mortar coating has high film strength, good combination with base, and can be directly attached to ceramic tiles, which is economical and practical. However, because it is a rigid waterproof material, it is not suitable for the renovation of new houses that may have settlement. Generally speaking, among all kinds of coatings, polyurethane has the best performance, acrylic acid and JS coatings have the best cost performance, and mortar coatings are economical and practical. 6. What are the main considerations when purchasing materials? First, waterproof performance, and then environmental protection performance. Waterproofing is a hidden project. Tile after waterproofing is completed. If toxic materials are selected, toxic gases will be released for a long time, just like the "toxic gas explosion bomb" buried in Canada, which is difficult to disassemble and replace. Therefore, the environmental protection of materials is also an important aspect of purchasing materials.

Waterproof materials are divided into three types: rigid, flexible and rigid-flexible, 1, and the ratio of flexible mortar: emulsion to mortar is 5: 4, which is elastic and will not affect the waterproof effect even if the base is deformed and cracked. It is mostly used for meeting water surfaces such as walls and floors, but not for back water surfaces such as top surfaces. If the waterproofing is not done well and there is water seepage, it is easy to wrap it up and seep. 2. Rigid mortar is also called rigid mortar: the ratio of emulsion to mortar is 1: 4. After brushing, the coating does not need to be treated, which is convenient for direct tiling. After curing, cement blocks are formed, which will not leak, and the waterproof effect of the back water surface is very good. 3. Polyurethane: it can be used indoors and outdoors. After brushing, it is very thick, about 3 mm, and the elastic tension is above 300%. Very elastic, any base material cracking will not cause it to crack, and the waterproof effect is good. 4, acrylic: acrylic pure liquid, ready to use when opened. Water-based, water-soluble, easy to combine with ground cracks, forming a solid waterproof layer, waterproof effect is better than flexible mortar. How to choose waterproof material 1, paint pollution can not be ignored. Indoor decoration waterproof layer must reach a certain relative thickness in order to have waterproof function. Therefore, the amount of materials used is relatively large, and once inferior waterproof coatings are used, the indoor environment will be polluted for a long time. Some tar-containing polyurethane waterproof coatings are very high in molecular weight, volatile and easy to deposit indoors. Excessive inhalation of this gas will lead to death in a short time. Therefore, the choice of waterproof coating must not be taken lightly. 2. There are many kinds of waterproof coatings with different uses. Waterproof coatings can be roughly divided into three types: modified asphalt waterproof coatings, polyurethane waterproof coatings and silicone rubber waterproof coatings. 3. Brand paint is guaranteed. At present, the management of building materials market is not standardized, and there are many fake and shoddy products on the market. Conditional consumers should choose a relatively good brand when purchasing. Real environmentally-friendly waterproof materials should have test reports, product test reports and product certificates issued by nationally recognized testing centers. 4. Pay attention to the manufacturer's service measures when purchasing waterproof coatings. The above is all the knowledge about what materials are used for family waterproofing and how to choose waterproof materials. After the above introduction, we have a further understanding of this problem and should know how to choose waterproof materials. I hope the above article can help you.

1, the product waterproof coating has good waterproof performance, and the waterproof quality determines the quality of a product. So when you choose, you must choose a waterproof coating with good waterproof effect. 2. Look at the environmental protection and waterproof of the product, which belongs to concealed engineering. After waterproofing is finished, you can start to stick bricks. If you choose toxic waterproof coating, it will release toxic gas for a long time, which is harmful to people's health. 3. The authenticity of waterproof coating depends first on the outer packaging of the product, whether the color is bright, whether the handwriting is clear, and whether there is product name, weight, origin, certificate of approval, etc. Marking according to specifications. Big brands have exclusive anti-counterfeiting labels, so pay special attention when buying.
