In home decoration, the most non-latex paint that comes into contact with consumers is none other than. As long as it is painted on the wall, it can't live without it. For consumers, whether it is to buy or paint, it is very troublesome, quality, environmental protection, price, everything must be worried, the following Suzhou home network Xiaobian brings you experience in buying wall paint, I hope to help you choose It is more worry-free when buying latex paint, and it is more comfortable during construction. Coatings are generally classified into water-based paints and oil-based paints. Latex paint is a type of water-based paint. It is mainly used for painting interior and exterior walls of homes, and it is the most widely used paint variety. Nowadays, the latex paint on the market is really "small flowers and fascinating eyes", and the brands, specifications, grades, functions and colors are all different. On the price, 5 liters range from tens of dollars to four or five hundred yuan; functionally, from scrubbing, covering cracks to anti-mildew and antibacterial, latex paint is more "full effect"; color, red orange yellow green blue blue purple , what color you want, the color machine can call you out. TOP1: How to choose wall paint 1. See the market through comparative experiments The purchase of latex paint, consumers may be most concerned about environmental protection and price. The most important environmental index for latex paints is the content of volatile organic compounds (VOCs). National standards stipulate that the VOC content per liter of latex paint should not exceed 200 grams. In order to facilitate consumers to purchase latex paint, the China Consumers Association recently conducted a comparative trial of 83 interior latex paint products in conjunction with Beijing, Shanghai, Guangdong and Sichuan provinces. 2, brand paint environmental protection is more assured According to the results of the release, the environmental performance of latex paint is basically up to standard. The content of volatile organic compounds (VOC) and soluble heavy metals in all samples are in line with national standards; only one sample of formaldehyde exceeds the national standard limit. Because the 83 samples used in the trial were purchased from 19 building materials markets or supermarkets in Beijing, Shanghai, Chengdu and Guangzhou, they covered major international and domestic brands and local brands, as well as products of the same brand and different price points. Therefore, consumers who pay attention to environmental protection can give priority to the purchase of branded latex paint. Special reminder: When buying latex paint, you should go to the reputable building materials market. Most of the mainstream brand products in the formal building materials market have reached the national standard. 3, the higher the price is not better performance According to the test results, the price issue that consumers are most concerned about is not the higher the price, the better the performance index. The price of latex paint on the market varies greatly, and the price per liter of 83 samples ranges from 7 yuan to 117 yuan. Compared with the highest price of 117 yuan per liter and 63.5 yuan per liter, the test results of environmental performance, hiding ability, stain resistance, and mold resistance are not significantly different. The two commodities with different unit price differences have their own advantages and disadvantages in comparison of performance indicators. Special reminder: When purchasing such products, you should use good cost performance as the purchase standard. Consumers should choose the appropriate characteristics of the latex paint according to the different functions of the room. For example, in the bathroom and basement, it is better to choose milder mold resistance. The kitchen and bathroom should be selected to be resistant to stains and scrubs. The latex paint with certain elasticity is suitable for covering cracks and protecting the wall surface. Choose a multi-functional product that suits you. In addition, it has also been found through inspection that there is a very close relationship between the various properties of the coating products, and even mutual constraints. For the popular multi-functional products on the market, the single performance may not be outstanding, but the overall performance is generally good. TOP2: Paint construction avoids three traps The paint itself is a semi-finished product. If you want to achieve the perfect final result, in addition to the quality of the paint 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, the choice of a formal and reputable home improvement company certainly has quality assurance. But some "road guerrillas" can easily get consumers into a trap. Trap one: low price temptation Now the oilmaker's offer is getting lower and lower. Some oil workers offer a total price of 16 yuan to 18 yuan per square meter (including paint prices and wages), if only a simple brush is as low as 6 yuan to 7 yuan. Manager Zhou reminded consumers that the low price should be credulous. If you really paint at these prices, sometimes the cost of the paint is not enough. The normal paint quotation decoration company is generally about 30 yuan (including the price of paint). Low-price traps generally entice consumers through low prices, and then make up for the low-cost losses by taking kickbacks, looking for various reasons to advance the wages and then spreading the money. The most important thing is that the price is not guaranteed. Special reminder: If consumers only want to deal with the wall, in addition to looking for a formal home improvement company, you can also find a manufacturer. Now some paint manufacturers also provide value-added services for painting. Trap 2: Stealing the column Latex paints are generally classified into primers and topcoats. If you want to paint the wall, the normal painting process is to first make a wall treatment - putty putty, then brush the primer and topcoat. The primer mainly serves to seal and prevent alkali. And now some oil workers like to do their hands and feet on the primer. Because the topcoat will be brushed after the primer is applied, the owner can't see the effect of the paint. Manager Zhou encountered a case in which the painter used the owner's busy work and did not have time to stare at the renovation. The 5 liter, 240-yuan, alkali-resistant paint purchased by the owner was replaced by a low-end product of 18 liters and 180 yuan. The owner was unable to detect any changes in the wall in a short time. The last loss is still the owner. Special reminder: If the owner is available, you can watch the painter open the bucket while painting. It is very difficult to replace the latex paint after it has been opened. Trap 3: Cut corners Latex paint is a water-based paint. Dilute by adding a certain proportion of water during construction. Paint brands vary in the proportion of water added from 10% to 30%. Some oil workers deliberately increase the proportion of water in order to save trouble or save paint, and the highest added water is more than 50%. The consequence of water mixing is that the hiding ability of the latex paint is greatly reduced, and it is impossible to cover the crack and protect the wall surface. Special reminder: water is easier to find through visual inspection and touch. If you want to choose the latex paint that is most suitable for the decoration style of the house, there are still many details to be aware of when purchasing the latex paint. Detail 1: Look at the second and third hands At first glance, look at the outer packaging and environmental testing reports. Generally, the front of the latex paint will be marked with the name, trademark, net content, composition, usage and precautions. Pay attention to the production date and shelf life, the shelf life of each brand of latex paint is between 1 and 5 years. Buy products that have been produced in the near future. Nowadays, general brand latex paints have environmental test reports or test sheets. Consumers can see that the test sheet has a detailed understanding of the environmental performance of latex paint. The test report has a standard for the detection of VOC, free formaldehyde and heavy metal content. The national standard VOC should not exceed 200 grams per liter; free formaldehyde should not exceed 0.1 grams per kilogram. The second is the mass component. In general, a quality qualified latex paint is about 7 kg in a barrel of 5 liters; about 18 kg in a barrel of 18 liters. There is also a simple method to lift the paint bucket. The normal brand latex paint can not hear the sound, and it is easy to shake the sound to prove that the latex paint has insufficient viscosity. Three hands are hands-on detection. The high-quality latex paint is relatively viscous, milky white liquid, no lumps, uniform after stirring, no odor. Otherwise it indicates that the latex paint has quality problems. It can also be spread evenly on the fingers, and the conjunctiva is dried within a few minutes. The conjunctiva has a certain ductility and is a safe coating. Detail 2: Colorful colors should be noted The color of the current latex paint is no longer monotonous white, and many consumers are more willing to light up their lives with colorful colors. On swatches and paint buckets, the color that consumers see and the effects they end up on the wall are not necessarily the same. Because the color of the paint is not only affected by light, but also by the area of ​​the paint. When a color is applied to a large area, the color usually increases, so you can choose a slightly lighter color.
