Real green paint must have the "ten ring" logo issued by China Environmental Label Product Certification Committee, and don't just look at the word "national standard" on general paint, because it is only the "access standard" for indoor wall paint to enter the market.
Look at the paint. The protective glue layer of high-quality colorful coatings is colorless or yellowish and clear.
Smell the paint for a pungent smell. Toxic paint may have no smell, but it must be toxic if it smells.
If the coating has serious delamination, the quality is poor. Stir gently with a stick, and the coating stays on the stick for a long time after lifting, covering evenly, indicating that the quality is better; Gently twist with your hands, the thinner the better.
Check the product quality inspection report carefully, especially pay attention to the total organic volatile content (VOC) of the paint. At present, the national standard stipulates that the VOC content of coatings should not exceed 200mg/l, and the better coatings are below 100mg/l, while the environmental protection coatings are close to zero.
Ask about the solvent. Good brands will limit the use of toxic solvents. Generally speaking, after paint dries, its solvent can basically volatilize, but there is a process, especially for paint cured at room temperature.
