The World Health Organization has issued a statement on the safety of paints, saying that paint has become the "main trigger point" in the incidents that cause children's lead poisoning. Because children are likely to be exposed to leaded paint through furniture, door frames, walls, toys, etc. Therefore, consumers are also urged to protect children's health and avoid using lead paint. So as consumers, in the home improvement process, how should we choose a safe and environmentally friendly coating? The market has a wide range of paint products, not only the variety of products, but also the quality of the products is even better. Many manufacturers claim that their paint products are "national standard" coatings or "green standard" coatings. Is this true or false? Next, each friend may wish to use the Xiaobian to paint the pulse market, through the "look", "smell", "question", to purchase.
One, hope" - good at observation
"Seeing": In the process of coating purchase, the so-called "look" means: 1. Look at environmental monitoring reports and packaging. The name, trademark, composition, and net content of general paints are all necessary marks on the outer packaging of latex paint; 2. Pay attention to the production date and shelf life of paints; 3. Observe the contents of VOC, free formaldehyde and heavy metals on environmental protection test sheets. Such as the test results are exceeded.
In addition to the above content we can understand through the outer packaging of the paint when we are purchasing, then the paint quality inside the paint bucket can also be understood through the “lookâ€. It is generally not allowed to open the container when the paint is selected. Therefore, consumers must carefully check the contents of the paint before using it for unpacking. 1, the main paint surface can not have a hard skin phenomenon, paint liquid without impurities, uniform color and transparent, and paint should have good fluidity; 2, curing agent requirements: should be water white or light yellow transparent liquid, no stratification And condensed phenomenon, clear and transparent, no impurities; 3, thinner (scientific name "Tian Na Shui", commonly known as "banana water") requirements: paint liquid clear and transparent, no impurities, and good dilution.
Second, "smell" - willing to listen
“Smellâ€: In the process of real paint purchase, relying solely on “look†to judge the quality of paint is not enough. To buy a truly healthy and environmentally friendly coating, we also need to smell the paint. Generally, the real environmental protection latex paints are water-based, non-toxic and tasteless. If everyone has smelled odor or industrial flavor when they are buying, then the paint is recommended not to buy. In the specific purchase, if the permission of the business, we can also use a stick to stir the paint a little to see if there is no smell. If so, we must also pay attention to the quality of the purchased paint.
Third, "Q" - diligently inquiries
“Qâ€: As the third step in identifying the safety and quality of coatings, it is also essential to ask related indicators. There are many paint products, and we do not rule out that the paints we buy may not clearly mark their indicators. In this case, we must let the sales staff answer the paint indicators in a responsible manner. In addition, the paints we buy will vary depending on the parts and materials used for decoration. For example, the paints selected for bathrooms, kitchens, etc., should be waterproof, mold-proof and easy to clean; The general metal base and wood base layer is also the best choice for solvent-based coatings.
Fourth, cut" - learn to sum up
“Cutâ€: As the final step in identifying the quality of the paint, it means that everyone needs to weigh the amount of paint when purchasing the paint. According to an experienced source, a typical quality latex paint has a weight of about 7 kilograms for a barrel of 5 liters of paint, and a bucket of 18 liters of paint has a weight of about 25 kilograms. In addition, in order to help everyone love to identify the quality of the paint, we can also shake up the paint bucket to see if there is no sound, the general regular brand paint can not hear the sound in the case of shaking, if you shake the paint will There is a sound, then it means that the viscosity of this coating is not enough.
Fifth, the following small points should also pay attention
1. The more elastic and elastic coating products of coatings, the less cracks are likely to appear after painting.
2. The scrubability of the paint, the higher the scrubability, the greater the density of the paint film, the better the brushing effect, and easy to clean.
3, pay attention to check the anti-mold paint.
4, the coating of the coating, the stronger the coverage, the wall paint on the grass-roots level of the coverage of the better, it is ideal for second-hand housing wall decoration.
5. For places with large areas of brushing, it is recommended to use coatings with good stain resistance, aging resistance, color retention and adhesion.
6. For places with small brushing areas, it is recommended to use paints that have fireproofing, mildew proofing, antifouling properties, and easy brushing.
7, for places with high humidity, such as bathrooms, kitchens, etc., it is recommended to choose water-resistant, fire-retardant, mildew-proof, dirt-resistant performance and easy brushing paint.
8. For concrete and cement base surfaces, the selected coating should have good alkali resistance and hiding.
9. For lime and gypsum board wall surface, more paints can be selected, but not all paints are applicable. For example, JHN841-1 scrub resistant interior wall paint is not applicable.
10. Non-alkaline coatings should be selected for paints painted on wooden surfaces because alkaline paints can damage the wood base.
11, when the temperature is lower than 5 °C, latex paint should not be selected, so as not to coating the film is not good, resulting in cracking, falling off and so on. At temperatures below 0 °C, solvent-based coatings should be selected.
The knowledge about coating purchase is introduced here and I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
