As a "outer coat" for household use, paint is a protective film for household items. How to choose a paint product with proper function and good effect, instead of being led by the merchant's propaganda? Consumers open the hidden secrets of paint to help people choose paint more rationally.

It’s not wise to just look at "N in 1"

Those who have bought paints in the building materials market are often stunned by the so-called "three in one", "five in one", "all-in-one" and so on. It is understood that 90% of manufacturers and merchants on the market currently sell "N-in-one" coating products. In fact, the “N-in-one” with many names is not only an ordinary consumer, but also a professional who has been engaged in paint sales for many years. It is not easy to understand the nuances. “N-in-one” is mostly interior wall paint. As the name implies, several functions are integrated into the product. For example, three-in-one means that the product has three functions, and so on. Five-in-one is five functions, ten-in-one is ten functions, and all-in-one is all functions of latex paint.

According to industry sources, when the original latex paint was first promoted in the market, consumers knew little about the product attributes. Although some merchants used the names of “luxury”, “excellent” and “noble”, consumers were difficult to accept due to inaccurate product claims, and promotion was very difficult. In 2000, in order to visualize and materialize the performance of the products, Nippon's first three-in-one elastic latex paint immediately seized half of the country. In order to avoid the aggressive momentum of Nippon, Dulux chose to break through in the high-end market and also directly launched the “five-in-one” latex paint. After watching the "N-in-one" products accepted by the market, domestic coating companies followed suit, some slightly changed, and some completely imitated, resulting in a variety of "N-one" products currently on the market.

In fact, no matter how many in one, it is nothing more than a few performance indicators, not as magical as the individual business bragging. In the national standard GB/T9756-2001, three essential functions of latex paint are specified, namely scrub resistance, alkali resistance and hiding rate. “As long as the paint products that meet the national standards can basically meet the needs of ordinary households.” He said that “super strong elasticity, waterproof and breathable, anti-fouling, clean taste, excellent leveling and fast drying” are only derived. Functional or construction performance. For the former, many multi-functional paints only highlight the scrub-resistant function. The anti-alkali and hiding rate functions are rarely involved, and their subsidiary functions are overwhelming. For the latter, unlike the popular American DIY, most owners in China will choose Let the professional construction personnel carry out the construction, so the construction performance is secondary to the owner. "N-in-one" is more white, and its marketing significance is far greater than the differentiation of product performance.

Special paint is not necessarily the best choice

Many merchants regard product attributes as product features, highlighting the "N-in-one" or "full-effect" selling point, allowing consumers to think that they can spend less money to buy better products, and when they feel "value", Many paint companies have also begun to focus on the "specialization" of home space, from the exterior wall to the balcony, from the kitchen to the bathroom, from the bedroom to the living room, its open tentacles began to meticulously into every corner of life.

As far as the current market is concerned, such things as "kitchen-specific paint", "banner-specific paint", "outer wall paint", "dark paint", "art paint", "net taste soft paint" and "Special paint for children's pregnant women" and many other specialized products. For many consumers, on the one hand, they may think that these enterprises are strong and technically professional; on the other hand, they feel that they are easy to use and are willing to pay more for special paint. But are these products really special?

According to industry insiders, these products with special paint flags are not much different from the general standard paints. He said that architectural decorative coatings mainly include three types: exterior wall paint, interior wall paint, and wood paint. Because of the large difference between indoor and outdoor environments, the performance requirements of coatings are significantly different. “In addition to the difference in environmental indicators, the requirements for anti-aging and acid and alkali resistance are also different.” In fact, “paints for children’s pregnant women” only add some aromatics and nano-materials, as to how many negative ions can be produced. The role of these negative ions on the human body is not only based on standards, but also objectively difficult to measure. Basically, the company has the final say.

In fact, there is no obvious difference in coating performance between kitchen, bathroom, living room and bedroom. From the point of view of use, tiles are obviously more advantageous in terms of anti-fouling and cleaning than the so-called “kitchen-specific paints”. “Furniture and kitchen-specific paints” are only suitable for those who pursue individuality, style, and cooking at home. And many medium and high-grade paint products are actually not inferior to special paints in scrubbing and moisture resistance. Zhu Jiangming also said that in order to have high gloss and good moisture resistance, only the resin content in the paint is high; and the so-called "dark paint" can completely add various color pastes to the white latex paint. Manual or mechanical mixing is achieved.

Choose "paint" tips

Everyone pays attention to the problem of paint and coating. The reporter has sorted out a few points, hoping to give you a reference for readers who are worried about choosing "paint".

The first is environmental protection. It is understood that the volatile organic compounds in the paint and wall paint will be gradually released after one year of painting. Therefore, buy paint and paint, the first thing, look at the product quality inspection report, do not show you or say no Merchant, you can refuse to buy. The most important environmental indicator for coatings is the VOC content.

The second is the color. It is not easy to decorate once. Every owner wants the home to be beautiful and bright. Many times the color of the wall paint selected is carefully selected by everyone. Everyone should be cautious when choosing colors, see clearly and start.

The third is the effect of the paint film. In the field of coatings, the effect of the film is a more professional problem, you can pay attention to the following points:

1. The elasticity of the paint, that is to say the product with greater elasticity, the less the crack is caused when the wall is painted.

2. The scrubberability of the paint. The higher the scrubtability, the greater the density of the paint film, that is, the better the effect of the paint, and the easier it is to clean.

3. The mildew resistance of the paint, the weather in the south is relatively humid, especially now in the spring, it is easier to mold for areas that are easier to enter.
