Why do people who sell waterproof and leak-proof materials on Taobao ignore false propaganda (20-year life, 30-year warranty, 50-year warranty)?

Nobody cares, which means nobody is fooled. They can't sell it at all. If many people are deceived, they will definitely cast false propaganda. Besides, bad reviews can't run away. When shopping on Taobao, the first thing you see must be evaluation. Of course, there are other protection mechanisms, such as returning goods.

Now the Ministry of Housing and Urban-Rural Development is soliciting opinions and changing the waterproof design period to 25 years. It is not a single waterproof material, but a composite waterproof design, such as three layers of waterproof layers added together. I have come into contact with a German waterproof material, with a single coating, which can withstand 20 years of wind and rain, and 30 years if it is protected. It's really good, but it's too expensive Domestic single waterproof material should not have a life span of 20 years, and a 30-year warranty is a joke. Tar asphalt has long been banned in China.

Regarding waterproof materials, you still need to buy well-known brand manufacturers. Generally, there will be shops specializing in waterproof materials in county towns. If you don't know waterproof knowledge, you can ask them more. It is not recommended to buy a large number of waterproof materials online. Unlike paint, you can brush it yourself. Waterproofing is still very professional. If you don't understand, you will be easily fooled.

I hope I can help you, please adopt and pay attention, thank you. Thank you.
