How to identify the true and false paint of three trees
Identification method of true and false paint: 1. Check whether there is a factory name, address and registered trademark on the package, and whether there is a test report from the quality supervision department. If the instructions are unclear, please do not buy. The key depends on the factory certificate and the original inspection report of the quality supervision department. 2. See whether the product packaging is intact, and whether there is too much noise when shaking the paint tube. A loud noise means that the quantity is not enough. You can check the weight of a can of paint and compare it with the product packaging instructions. 3. Check whether the printed matter is clear and exquisite, and whether the packaging pattern is clear and exquisite. 4. After opening the paint tube, check whether there are impurities on the surface and whether the whole is clear. 5. Stir to see if there are lumps. 6. Is the smell pungent? 7, see if there is any discoloration and yellowing on the brushing effect.
