I. purchase of paint

1 It's best to shop around before buying, and learn more about relevant product information. For commodities with the same package and brand, we should consider comprehensively from the aspects of quality, price and service

2. Choose the paint according to different parts. For example, the paint used on the indoor wall should have the characteristics of strong adhesion, fine texture and pulverization; The paint for kitchen, bathroom and washroom shall be waterproof, mildew proof and easy to wash

3. When buying, you should choose different kinds of coatings according to different wall characteristics. Different materials and materials have different requirements for coatings. For example, polymer waterborne coatings should be preferred for concrete and cement mortar base; Various solvent based coatings are preferred for wood base and metal base

in addition, the shelf life of the coating is generally two years. Some brands do not indicate the expiry date on the packaging barrel, only the production date, so it is necessary to carefully identify when purchasing. When purchasing paint, pay attention to the use of auxiliary materials in construction, especially glue and primer. Even if environmental friendly paint is selected, it cannot be sloppy in substrate treatment. For example, 107 glue contains harmful substances, and relevant national regulations have expressly prohibited its use in home decoration

second, how to identify green coatings

environmental protection experts believe that coatings are the second largest source of pollution in modern society, and the emergence of green coatings is undoubtedly a guarantee for health. The so-called green paint is the paint that can protect the environment. It is non-toxic and odorless, and can inhibit the growth of mold

when choosing paint, how to identify whether it is green paint? First of all, when buying, we should choose brand products and see whether the coating meets the national mandatory standards; Secondly, we should carefully check the quality inspection report of the product, especially the VOC content in the quality inspection report. The national standard stipulates that the VOC limit is not more than 200g per liter, the better coating is less than 100g per liter, and the environmental protection coating is close to 0. If you can get the consent of the seller, you can ask the seller to open the paint bucket and test it yourself. If there is serious stratification, the quality is poor; Stir gently with a stick. After lifting, the paint stays on the stick for a long time and covers evenly, indicating good quality; Twist gently with your hand. The more delicate, the better

most of the non environmental friendly coatings have pungent odor due to excessive VOC, formaldehyde and other harmful substances, so we must be careful when choosing. Of course, don't buy products that smell very fragrant. Generally speaking, this kind of paint is added with essence, and the additive itself is a chemical product, which is difficult to ensure environmental protection

third, how to identify true and false paint

first, observe its shape. The paint contains less impurities, and the line is painted well if it is milky white after stirring

secondly, check its color. Good paint is naturally divided into three layers, with the surface of soy sauce or pork liver color, the middle layer of light yellow and the bottom layer of gray white; All one color is fake paint

finally, smell it. Good paint has aromatic or sour smell. If there is corruption or other strange smell, it is deteriorated paint or fake paint. Paint that has not dried for a long time is bad paint no matter how good it is
