In modern home decoration, waterproofing is an important part. Under normal circumstances, bathrooms, kitchens and bathrooms should have waterproof layers. However, many families do not have a clear concept on how to choose a qualified waterproof coating. In addition, there are many mixed coatings on the market. Brands are difficult for consumers to choose, which is easy to bury hidden dangers for accidents.

There are mistakes in home decoration

The waterproof project of home decoration is a relatively hidden project. Some families often mistakenly believe that the area of ​​indoor decoration waterproof projects such as bathrooms and kitchens is not very large. After using waterproof coatings, cement and tiles will be used on them, which will not cause pollution. In fact, the waterproof layer of interior decoration must reach a relative thickness to have waterproof function. Therefore, the amount of material used is relatively large, and once inferior waterproof coatings are used, the indoor environment will be polluted for a long time.

In addition, some tar-containing polyurethane waterproof coatings have a very large molecular weight of tar gas, which is volatile and easy to deposit indoors. Excessive inhalation of this gas will cause death in a short time. Therefore, the selection of waterproof coatings must not be taken lightly.

There are many types of waterproof coatings

At present, the waterproof coatings on the market can be roughly divided into three types: one is modified asphalt waterproof coating, which is mostly used with glass fiber cloth, and the engineering is relatively complicated. The project price is about 100 yuan per square meter; the other is polyurethane waterproof coatings, which are generally diluted with organic solvents containing toluene, xylene and other components, which are toxic. There is also a newly launched silicone rubber waterproof coating, which mainly uses polymer composites.

It has good waterproof and moisture-proof functions, and the construction is relatively simple. The price per square meter is about 30 yuan.

right.

It is suggested that qualified families can try to use silicone rubber coatings. It is understood that there are not many manufacturers capable of producing such products in the domestic market. Consumers must look for manufacturers when choosing.

Brand paint is guaranteed

Families should master some basic common sense when choosing waterproof coatings. At present, the management of building materials market is not standardized, and there are many fake and inferior products on the market. Conditional consumers should choose relatively well-known brands when purchasing. The real environmental protection waterproof material should have the test report, product test report and product certificate issued by the nationally recognized testing center.

When consumers buy waterproof materials, they should also pay attention to the origin indicated on the product packaging. On the packaging of imported products, the company name will be indicated in detail in the column of origin, while counterfeit products are generally only indicated with the place of export and will not involve the production company.

In addition, consumers are reminded to pay attention to the manufacturer's service measures when purchasing waterproof coatings. Generally, regular manufacturers will have relatively standardized pre-sale, in-sale and after-sale services when selling products, and some well-known brands will also promise free maintenance and a long waterproof warranty period. If the manufacturer cannot provide a relatively complete service, it is recommended that consumers choose another product.
