1. When we buy paint, we must see if the information on the product packaging is complete, whether there is a 10-ring certification mark, or you can take a look at the product test report, pay attention to whether the environmental indicators VOC, free formaldehyde, heavy metals, etc. In line with national standards. The smaller the voc content, the more environmentally friendly.
2. The eco-friendly paint has a light scent and no pungent odor. We can let the merchant open the sample paint can lid and smell the smell of the paint. We also need to see if the appearance of the paint is even and delicate after the can is opened, and it is not flowing when it is stirred. If it is, it means a good paint.
3. The finer the paint, the better the quality of the paint. The good paint feels smooth and smooth. If we touch the paint surface with a noticeable graininess, the paint contains impurities. We can also use a toothpick and other items to draw a paint film. If there are obvious scratches, it means the hardness of the paint is low. It is best not to buy it.
4. When we choose paint, it is best to choose matching products, such as primer and topcoat, it is best to choose the same brand. When choosing a product, it depends on the shelf life of the product. It is best to choose a product with a long shelf life.
