The nature of products to buy is very important. There are various types of waterproof coatings on the market currently sold, such as "slurry" and "slurry". There are also water-repellent coatings classified into type I and type II. Some people say that type II is more suitable for indoor use, but Guo Yang Lei introduced that, as long as the purchase knows what kind of nature waterproof coating on the line, the name is not important; I and II type of this classification is only the definition of the individual business, the industry does not have an authoritative division and specific standards. When consumers purchase, the most important thing is to look at the nature of the waterproof coating, generally marked as "universal" or "flexible", and then look at the ratio of mortar and emulsion, such as 12kg +8.4L; the price is also the product An important reflection of quality is that two buckets of paint of the same capacity will have a question mark on product performance if the price difference is too large.

There are products marked "kitchen and kitchen use". In fact, this is just a gimmick. General indoor waterproof paint can be used for kitchen and bathroom.

Common scams in paint purchases:

One, only sales are not service

Most consumers only pay attention to the effect when they purchase paint, and ignore the service. In fact, the coating services include pre-sales consulting, construction guidance and advice during the sale, after-sales maintenance, etc., and the current coating brand does not have direct sales outlets set up by the manufacturers, all of which are resellers of products sold by the dealers, and some are not standardized. There is no service organization at all.

Many businesses only have an introduction to the product when they are selling, but they do not mention after-sales service. When the wall appears faded, powder off and other issues, nowhere to solve, most manufacturers require consumers to resolve directly with the dealer, even if the time promised home repairs, the time will be delayed again and again, and ultimately nothing.

72 Hyun home network to remind consumers: 1, under the conditions of economic conditions, try to choose brand-name products; 2, at the time of purchase on the sales staff to "site guidance" requirements, no after-sales service manufacturers generally: "No Necessary, "will not be a problem" and other arguments to shirk; 3, to the manufacturer directly call, ask the time of home repairs, good manufacturers will promise to within 24 hours of on-site service.

Second, garbage paint packaging

At present, some foreign brands of paint on the market are actually foreign-made garbage paints (overdue products) imported at a very low price, refilled at home, affixed foreign brands, replaced foreign packaging, and used consumers' Chongyang psychology is sold in the market. The profit of this coating is about 4-5 times.

This kind of product does not have the basic performance that the coating should have at the same time, will appear powder, decolorize and waits for the phenomenon within one or two months after use, and it is not environmental protection, some have already turned into taste, bring great hidden danger to human body's health.

72 Hyun home network to remind consumers: 1, understand the background and history of manufacturers; 2, buy a mature brand.

Third, the local product sells the ocean price

There are also many businesses that use consumer products that are not easily identifiable, and have given foreign names to some domestically produced products. Prices have doubled. It is understood that the practice of these products is to earn profits, many pure imported brands are now produced in the country, but the raw materials used are imported, these raw materials are of stable quality and excellent performance. The use of domestic raw materials, the local product quality is not stable, but put on a foreign brand to sell high prices, if consumers buy fake goods, spend a lot of money not to say, the effect can only look at their luck is good or bad. Lack of good luck is often a result of economic losses and spending more money, but it does not necessarily use real good products.

72 Hyun home network to remind consumers that this counterfeit foreign brands of methods exist in a variety of building materials, but generally it will take a long time before showing all kinds of misdeeds, if the owners of economic conditions do not allow, it is better to choose pure domestic brands.

Fourth, deliberately exaggerating the function

The most typical is the so-called five-in-one product that is now prevalent in the paint industry. This type of business is mainly based on consumer irrationality, lack of knowledge of paint products, and lack of comprehensive consideration of information. Businesses usually deliberately exaggerate the basic functions that common coatings should have, and carefully look at the packaging of five-in-one products. These five functions include: mildew prevention, easy scrubbing, covering micro-cracking, lasting beauty and scent. If the first three items are still considered to be a function, the last two items are entirely for the purpose of reconciliation. According to industry analysts, the anti-mildew and coverage functions of coatings are basic functions. Now they are used by businesses to make selling points. For these two functions, consumers often spend 20% more.

In view of this situation, installed cool network can only remind consumers to pay attention to their wallets, do not blindly believe that the business's hype, understand their own needs, select the appropriate product.

Five, chaos concept

The principle of this kind of scam is that merchants seize the concept of a consumer not familiar with the hype and create selling points. Such as zero-VOC coating, relevant personage analysis, under the current market situation, appear zero VOC coating is unrealistic at all. It is understood that in the process of making paints, there are some additives that are indispensable. If the basic functions of these paints are reduced, these additives will inevitably bring VOCs under the existing technological conditions. Really zero VOC, without affecting the basic function of the paint, the price will be unacceptable to consumers.
