First, smell it.
After opening the lid, the truly environmentally friendly latex paint should be water-based, non-toxic and tasteless, so it is not an ideal choice for users who smell pungent or industrial essence. After a period of time, genuine latex paint will form a thick elastic oxide film on its surface, which is not easy to crack, while defective products will only form a thin film, which is fragile and has a spicy smell. Stir the latex paint evenly with a wooden stick, and then pick it up with a wooden stick. When high-quality latex paint flows downwards, it will form a fan shape. Touch with your fingers, genuine latex paint should feel smooth and delicate. Real latex paint has no irritating smell, while the low-grade water-soluble paint of fake latex paint may contain formaldehyde, so it has a strong irritating smell.
Second, look at the packaging.
Consumers should carefully check the packaging when buying paint. Because of the volatility of polyester paint, the product packaging should be sealed, and there should be no leakage. Metal packaging should not rust, otherwise it means poor sealing or too long time; Also carefully check the production date and shelf life, and remove the inferior paint from the outer packaging first.
Third, look at the VOC content
VOC of coatings refers to the total amount of organic compounds contained in coatings. The volatilization of organic compounds will do harm to the environment and human body, so the amount of these solvents should be minimized.
Fourth, observe the color.
The protective glue layer of high-quality coatings is colorless or yellowish, and there are usually no floating objects on the surface.
There are many kinds of green paints, such as Dulux, Nippon, Sanshu, Bauhinia and Elephant Paint, which can be purchased according to your own needs.
