In home decoration, latex paint is the most contact with consumers. As long as it is painted on the wall, it can't be separated. ?
Coatings are generally divided into water-based paints and oily paints. Latex paint is a water-based coating. It is mainly used for painting the interior and exterior walls of families, and it is the most contact with consumers. ?
Latex paint on the market now is really dazzling, with different brands, specifications, grades, functions and colors. ?
In terms of price, the 5-liter package ranges from tens of yuan to four or five hundred yuan; Functionally, latex paint is more "full effect" from scrubbing resistance, covering cracks to mildew prevention and antibacterial; In terms of color, red, orange, yellow, green, blue and purple, whatever color you want, the palette can help you adjust it. ?
For consumers, buying or painting is very troublesome. Quality, environmental protection and price should be taken into account. The reporter interviewed a number of people in the industry, hoping to help you feel more at ease when purchasing latex paint and feel more at ease when constructing.
Shopping? Look at the market through comparative experiments
Consumers may be most concerned about environmental protection and price when purchasing latex paint. ?
The most important environmental protection index of latex paint is the content of volatile organic compounds (VOC). According to the national standard, the VOC content in each liter of latex paint should not exceed 200 grams. In order to facilitate consumers to buy latex paint, recently, China Consumers Association, in conjunction with consumers' associations in Beijing, Shanghai, Guangdong and Sichuan, conducted a comparative test on 83 kinds of latex paint products for interior walls. ?
Brand paint is more environmentally friendly.
From the published results, the environmental protection performance of latex paint basically meets the standard, and the volatile organic compounds (VOC) and soluble heavy metals contents of all samples meet the national standards. Only one sample has formaldehyde content exceeding the upper limit of national standard. Because the 83 samples used in the experiment were all purchased from 19 building materials markets or supermarkets in Beijing, Shanghai, Chengdu and Guangzhou, covering major international and domestic well-known brands and local brands, as well as products of the same brand with different price points. Therefore, consumers who pay attention to environmental protection can give priority to buying brand latex paint. ?
Special reminder: when buying latex paint, you should go to the reputable building materials market. The mainstream brand products in the formal building materials market have reached the national standard in environmental protection performance. ?
The higher the price, the better the performance.
According to the test results, the price problem that consumers care about is not that the higher the price, the better the performance index. The price of latex paint varies greatly in the market, with 83 samples ranging from 7 yuan to 1 17 yuan per liter. Compared with the highest-priced samples per liter 1 17 yuan and the samples with a price of 63.5 yuan per liter, there is no big difference in the test results of environmental protection, hiding power, pollution resistance and mildew resistance. However, there are some advantages and disadvantages in the comparison of performance indicators between the two commodities with large unit prices. ?
Special reminder: when purchasing such products, we should take good cost performance as the purchasing standard. Consumers should choose latex paint with corresponding characteristics according to the different functions of the room. For example, it is best to choose products with good mildew resistance in bathrooms and basements, and products with good stain resistance and scrub resistance in kitchens and bathrooms; Choosing latex paint with certain elasticity is conducive to covering cracks and protecting the decorative effect of walls; Choose a multifunctional product that suits you. ?
In addition, through inspection, it is also found that the properties of coating products are closely related and may even restrict each other. For the popular multifunctional products in the market, the single performance may not be outstanding, but the comprehensive performance is generally good. ?
Brush? Three pitfalls to be avoided in construction
The coating itself is a semi-finished product. In order to achieve the most perfect final effect, in addition to the quality of the coating itself, construction also plays a key role. ?
According to Mr. Zhou, the manager of the quality inspection department who has been engaged in the quality inspection of home improvement for a long time, it is of course guaranteed to choose a formal and reputable home improvement company. However, some "road guerrillas" can easily make consumers fall into the trap of brushing. ?
Trap one? Low price temptation?
Now the price quoted by oil workers is getting lower and lower. Some oil workers quote per square meter 16 yuan to 18 yuan (including paint price and salary), but if painting is simple, it is as low as 6 yuan to 7 yuan. Manager Zhou reminded consumers not to trust low quotations. If you really paint at these prices, sometimes even the cost of paint is not enough. Normal paint quotation decoration companies are generally around 30 yuan (including paint prices). ?
The low-price trap is generally to lure consumers through low prices, and then to make up for the loss of low prices by taking kickbacks, finding various reasons to advance wages, and then sharing them. Most importantly, low price does not guarantee good quality.
Special reminder: if consumers only want to deal with the wall, they can also find manufacturers in addition to regular home improvement companies. Now some paint manufacturers also provide paint value-added services. ?
Trap two? Stealing a column?
Latex paint is generally divided into primer and topcoat. If you want to paint the wall, the normal painting process is to do the wall treatment first-scrape putty, and then brush the primer and topcoat. Primer mainly plays the role of sealing and alkali prevention. ?
Now some oil workers like to tamper with the primer. Because the primer will be covered by the topcoat after painting, the owner can't see the effect of the primer at all. Manager Zhou encountered a case in which a painter took advantage of the owner's busy work and didn't have time to concentrate on decoration, and replaced the 5 liters of alkali-resistant paint purchased by the owner 240 yuan with the low-end products of 18 liters and 180 yuan. It is difficult for the owner to notice any change in the wall in a short time. In the end, it is the owner who suffers. ?
Special reminder: If the owner is free, he can watch the painter open the bucket during painting construction. Latex paint is difficult to replace after opening. ?
Trap three? Cut corners?
Latex paint is a water-based coating. During construction, a certain proportion of water should be added for dilution. The proportion of water added varies from 10% to 30% according to different paint brands. However, some oil workers deliberately increase the proportion of water in order to save trouble or color, and add more than 50% water at the highest time. The result of mixing water is that the covering ability of latex paint is greatly reduced, which can not cover cracks and protect the wall. ?
Special reminder: water adulteration can be easily found by visual inspection and touch. ?
Shopping details determine colorful quality.
If you want to choose the most suitable latex paint for house decoration style, there are still many details to pay attention to when purchasing latex paint. ?
Details 1? Look at it, weigh it and do it.
A look is to look at the outer packaging and environmental protection test report. Generally, the front of latex paint will be marked with name, trademark, net content, composition, usage and precautions. Pay attention to the production date and shelf life. The shelf life of various brands of latex paints ranges from 1 to 5 years. Try to buy the latest products. Now the general brand latex paint has environmental protection test report or test sheet. Consumers can learn more about the environmental performance of latex paint by reading the inspection sheet clearly. The test report has standards for the test results of VOC, free formaldehyde and heavy metals. The national standard VOC cannot exceed 200 grams per liter; Free formaldehyde shall not exceed 0. 1g per kilogram.
Second, weigh the weight. Generally speaking, the quality of qualified latex paint, a barrel of 5 liters about 7 kilograms; A barrel 18 liter is about 25 kg. There is also a simple way to lift the paint bucket. Regular brand latex paint can't hear the sound when it is shaken, and it is easy to shake the sound, which proves that the viscosity of latex paint is insufficient. ?
The third step is to open the can for testing. High-quality latex paint is viscous, milky white liquid, without caking, even after mixing, without peculiar smell. Otherwise, the latex paint has quality problems. You can also apply it evenly on your fingers, and the conjunctiva will dry in a few minutes. The conjunctiva with certain ductility is a safe coating. ?
Detail 2? Should we pay attention to the bright colors?
Now the color of latex paint is no longer monotonous white, and many consumers are more willing to light up their lives with colorful colors. ?
On the color swatches and paint buckets, the colors seen by consumers are not necessarily the same as the final effect on the wall. Because the color of paint is not only affected by the light, but also by the painting area. When a color is applied to a large area, it usually becomes heavier, so you can choose a slightly lighter color.
