How to distinguish true and false waterproof coatings?

1. Weigh. Many waterproof coatings on the market currently have weights that are slightly different from the weights marked on the barrels. Consumers can weigh them on site when purchasing to avoid being confused.

2. Query the anti-counterfeiting code. Nowadays, counterfeiters will also set their own inquiry telephone numbers and inquiry barcodes. Consumers can go to the website to find the website of the genuine trademark manufacturer, and follow the inquiry telephone number prompted on the website.

3. Check the waterproof effect. Take polymer waterproof materials as an example. For authentic products, you can use a knife to remove the rubber from walls and floors. It will not break when folded in half and is extensible. Many shoddy and counterfeit products are powdery, difficult to remove from the wall, and will break when folded in half.
