First of all, look at 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 don't buy it. The key depends on the factory certificate and the original inspection report of the quality supervision department.

The product is in good condition.

See if the product packaging is intact and there is too much noise when shaking the paint tube. Loud noise means there is not enough quantity. You can check the weight of a can of paint and compare it with the product packaging instructions.

Clear printing

Check whether the printed matter is clear and exquisite, and whether the packaging pattern is clear and exquisite.

Inclusion-free

After opening the paint tube, check whether there are impurities on the surface and whether the whole is clear.

Non-blocking

Stir to see if there is a lump.

No irritating smell

Is the smell pungent?

Brushing effect

See if the brushing effect is discolored and yellow.

Standardize market procurement

There are many brands of coatings, such as China Resources, Sanshu, Red Apple, Gareth and so on. Now the fake brand latex paint is hard to tell. I suggest you buy it in a standard market or a specialty store.
