Market: Three or four times the difference between different prices Wall latex paint is an essential material for residents' home decoration, and its quality directly affects the health of consumers. There are a lot of wall latex paints on the market, and the prices are very different. The same brand and the same kind of latex paint, because of different grades, the price difference is three or four times. The reporter discovered this problem in some decorative materials on the south bank of the city: the same brand, the same amount of wall latex paint, an ordinary bucket of more than 100 yuan, a mid-range bucket of more than 200 yuan, and the bucket body is marked with a formaldehyde-resistant green coating. The barrel is nearly 500 yuan. A staff member told the reporter that the general decorator is mostly buying ordinary and mid-range latex paint, and only the owner or the owner will purchase the top grade with the decorator. The staff member also pointed to the large wall of latex paint on the floor said: 200 ~ 500 yuan a barrel of brand-name wall latex paint can only brush 60 to 70 square meters (brush twice), add more water Can brush nearly 100 square meters. The quality of the better, big bucket of ordinary brand latex paint is 130 yuan, the effect of the brush will not be much worse. Trick: Use low-end products but offer high prices A decorator who has been in the renovation work for more than 10 years, Mr. Zhong said that the price of latex paint on the wall is most difficult to make clear, and it is also a kind of decoration material for “decoration of fishâ€. The price of good wall latex paint and ordinary wall paint is several times different, but the same color is used to paint on the wall. Only a long time can tell whether it is good or bad. If the difference in the price of wall paint is only doubled, or if there is more water, it is hard to see the difference. The same brand has different price of the wall paint, the decoration master quoted only a certain brand of latex paint, but did not say what the grade of latex paint, often in accordance with the brand's most high-end prices to the owner settlement, when buying Use the cheapest to buy, or buy the best one, and then put the cheapest latex paint in for mixing. There are also decoration masters who even pour vats of latex paint on the walls into famous brand latex paint buckets and impersonate brand-name emulsion paint to deceive the owners. According to the relevant person in charge of the Municipal Decoration Industry Association, some decoration companies or construction teams have trickery that the owners do not know when using latex paint. One trick: add water. According to the normal construction requirements, each litre of latex paint should be equated with 10% to 15% of water. In actual construction, water is often added to about 50%. Two tricks: cut material. General decoration company wall coating brushing materials quoted at 30 yuan per square meter, but the actual amount of paint is often only 30% of the standard amount of use. Three tricks: stealing work. In order to ensure the effect, the professional construction of the brush should be a two-coat finish primer, while the construction side only brush again primer, paint again. Reminder: Recognize the product packaging label and shelf life The relevant person in charge of the Municipal Decoration Industry Association reminded the public to understand the marking and shelf life of the goods when purchasing the wall paint. Qualified product identifiers shall have product grades, production units, implementation standards, date of manufacture, warranty period, storage instructions, and packaging specifications. According to the use of the place to choose paint. For wet areas such as kitchens and bathrooms, waterproof, mildew-proof and washable paints should be used. Other walls should be chosen for their good decorative effect, delicate coating, non-powdering, and certain scrub resistance. Also pay attention to the distinction between latex paint and water-soluble paint. As the cost of latex paint production is much higher than that of water-soluble paints, the so-called latex paints with a particularly low price in the market are likely to be fake water-soluble paints. After use, they can easily cause poor water resistance, powder fall-off and peeling off. Read the construction instructions carefully to see if you need to use the matching primer. If you need to use, use the same brand of supporting products as much as possible. Pay more attention to the construction operation process and pay attention to checking whether the brand and the budget report match. During the construction, pay attention to the amount of paint used, according to the requirements of standard construction procedures, the thickness of the primer is 30 microns, the construction area of ​​the 5 liters of primer is generally 65 to 70 square meters; the recommended thickness of the topcoat is 60 to 70 microns. The construction area of ​​5 liters of paint is generally 30 to 35 square meters. Related links: buy latex paint to see the smell touch (1) Look. See if latex paint has settlement or agglomeration.
