Check the packing details
Packaging is the first line of defense for product quality. Carefully check whether there is a clear factory name, address and registered trademark, as well as the inspection report of the quality supervision department. If the explanation is not clear, I advise you to think it over carefully.
Auditory discrimination quality
Gently shake the paint tube. If the sound is too loud, it may indicate that there is not enough. The weight of a bucket of paint is checked randomly, and compared with the product packaging instructions, it is difficult to distinguish between true and false.
Observe the printing quality
Printing on the package is also a key to judge the quality. Whether the pattern is clear and exquisite directly reflects the quality of the product.
Open cover inspection
Don't use it in a hurry after opening the paint can. First, check whether there are impurities on the surface and whether the whole is clear. Only in this way can the product quality be preliminarily judged.
Stir and explore the truth
Stir the paint gently to see if there is any caking. If so, it may be a sign of poor quality.
Odor recognition
The smell of paint is also important. If the smell is pungent, it may be of poor quality or harmful substances have been added.
Physical test
Finally, you may wish to actually brush it and see how it works. Whether there is discoloration or yellowing is an important basis for judging quality.
