1. Look at the surface of the paint. High-quality and colorful coatings The protective rubber solution layer is colorless or yellowish, and clear, the surface is usually free from floating objects; if there are floating objects, you must purchase it with caution.
Non-environmentally-friendly paints have excessive odor due to harmful substances such as VOC and formaldehyde, smelling pungent odors in paint, toxic paints may not taste, but paints with strange smells must have problems. Consumers need to buy carefully. Of course, do not buy products that smell very fragrant. In general, these types of paints have added flavors. The additives themselves are chemical products and it is difficult to ensure environmental protection.
2. If possible, ask the seller to open the paint bucket and test it in person. If the paint has serious stratification, it means that the quality is poor; after stirring gently with the stick and lifting it, the paint stays on the stick for a long time and the coverage is even, which means that the quality is better; the lighter the hand, the finer the better. No problem with the paint distributors, the use of open-lid sales methods, allowing consumers to intuitively paint the environmental protection.
3. Carefully review the product quality inspection report, paying particular attention to the total organic volatile content (VOC) of the paint. Organic volatiles pose a great danger to our home environment and to ourselves. Toluene, xylene, butanone, acetate, etc. are among the limitations, and we should minimize the amount of these solvents.
4. Less consumption consumption: consult the merchant about the number of painting times and the area of ​​painting, the calculation amount and the cost per square meter of material, not be deceived by the unit price of each group (barrel), paint from solid parts Membrane) and volatile matter composition, high solid content of 70% to 80%, low of less than 10% to 20%, low unit price is often very large consumption, costing more expensive and wasteful, and quality effect difference.
