Although most consumers prefer pure wood flooring, laminate flooring, that is, composite wood flooring, is not as expensive as pure wood flooring because of its high quality and low price. However, according to the statistics of China Consumers Association, composite wood flooring accounted for the majority in complaints about wooden floors.
Pick the floor: the map is cheap and careful
In September 2001, Professor Luo, who lives in Chegongzhuang, Beijing, and worked at Capital University of Economics and Business, bought a certain kind of composite wood flooring produced by Hunan Changsha from the Baihui Building Materials Market, including an installation fee of 70 yuan per square meter. After two months of use, the family found that the floor where the door was smashed was white, so it was suspected to be a counterfeit product. Later, after expert appraisal, the product bought by Professor Luo was not a composite wood floor, but a plate called melamine decorative veneer.
In general, the price of mid-range composite wood flooring is more than 100 yuan, including the baseboard, installation fee, auxiliary materials, and the price of 60-70 yuan per square meter of composite wood flooring, how difficult to say quality. Some unscrupulous merchants will cut the melamine decorative board without wear layer at all, and cut it into so-called “reinforced wood floorâ€. The wear resistance is only a few hundred or one thousand or two. The surface layer will be ground in a short time. Drop it. Associate Professor Luo is confronted with such a "black heart" businessman.
Experts remind consumers that it is best to buy well-known brands in the floor brand franchise stores, and the quality and after-sales service are more secure. Be careful with shops that operate several brands at the same time. Some of the floors are all foreign characters, there is no Chinese logo, or there is no manufacturer, and 80% are fake and shoddy products.

Wear-resistant revolutions: the higher the blow, the more you don’t believe
Wear-resistance number is an important indicator to reflect the quality of composite wood flooring. Consumers who have purchased experience will find that many merchants say that the wear-resistance number is particularly hovering when introducing products. It is obviously 6000 rpm, not to mention 18,000 rpm, or even 20,000 or 30,000 rpm.
In fact, whether it is European EN438.26 (old standard), EN13329 (new standard), or GB/T18102-2000 Chinese national standard, the highest limit of wear resistance is about 15,000 rpm (Abrasion resistance grade AC5), this AC5 The floor is a special floor used in special places, so it is extremely rare. The most common floors on the market are 6000-9000 rpm floor, and the so-called 18000 rpm or even 20,000 rpm floor is completely exaggerated by some merchants. game.
In fact, for household flooring, the floor with a wear resistance of 6000 rpm can be used for more than 10 years, and the commercial floor is qualified as long as it reaches 9000 rpm. Consumers do not have to pursue excessive wear resistance. It seems that buying clothes is not a bad thing to buy for 50 years. When purchasing composite wood flooring, it is best to ask the merchant to write the initial wear resistance number to the invoice, and once there is a problem, there is also a certificate.
In use: furniture placement
There was a problem with the floor at home. The first thing consumers think of is not the quality of the floor, but the problem of paving. However, Miss Liang, who works in the Ministry of National Security, knows by experts that the improper placement of furniture can cause problems.
At the end of December 2001, Miss Liang was located in the new home of Wanshou Temple. There was a 4mm crack in the joint of the composite wood floor in the middle of the room. Ms. Liang believes that there must be a problem with the quality of the floor, and she complained to the China Timber Distribution Association Floor Committee. The expert carefully surveyed Ms. Liang’s house and thought that the problem was not on the floor. Due to the dry climate in winter and the heating of the baking, the laminate flooring will shrink overall, generally small, and will not affect the appearance and use. On the two sides of the wall where Ms. Liang’s house and the floor pavement are parallel, there is a set of high-end audio equipment on one side, a large closet on the other side, and a set of sofas in front of the closet. When the air is dry and the wooden floor is contracted as a whole, the wooden floor on the side of the wall is pressed by the heavy object and cannot be shrunk, so it is concentrated in the center of the room to be released, so that the big hole is cracked.
Experts suggest that in the dry climate, it is best to maintain a certain indoor humidity, or move the furniture, do not put the heavy furniture too concentrated, so that the wooden floor is evenly stressed, there is room for gasping.
Paving the floor: Be careful and careful
There is no need to play keel when installing composite wooden floor. The laying is relatively simple, but it is not that anyone can lay the floor. Some consumers are not good enough to find a decoration team or carpentry for the sake of cheaper. It is better to find a wooden floor enterprise. Professional construction team provided. First, they have professional tools and experience, and secondly, there is a clear responsibility for laying accidents. However, the construction team is no better, and the users can't “make it bigâ€. It is necessary to create conditions for the paving of the wooden floor and good use in the future when the house is renovated. For example, the ground is cleaned and leveled, and the construction situation of the wooden floor construction personnel is explained in time.
In March 2001, a resident of Wolong Community in Beijing Asian Games Village installed a wooden floor for a few days. When he slept one night, he suddenly found that the ground was rising, not only drowning his own family but also soaking upstairs residents. It was originally the floor installer who used the electric hammer to break an aluminum-plastic pipe buried under the concrete floor when laying the bridge between the bedroom and the living room. This family thinks that this is the responsibility of the floor installer and requires compensation of 20,000 yuan. The investigators found that the pipe was connected to the kitchen water heater and the bathroom shower. It was modified by the decoration company's illegal operation rules without the approval of the property and without the approval of the gas company, and the owner did not. Tell the floor installer that there is a pipe underneath and therefore no compensation. The experience of this family has taught us a lot of lessons. When installing wooden floors, we must consider the direction of water pipes and circuits, and promptly inform the installers, otherwise it will easily lead to a major disaster.
Many consumers use wooden flooring to find that the composite wooden floor laid near the kitchen and bathroom is very easy to arch. This is because the decoration team often mixes the cement sand outside the kitchen and bathroom when laying the tiles in the kitchen and bathroom. In addition, the homeowner's decoration is willing to catch up with the construction period. As a result, the floor has not been dried and the floor is laid, causing arching. If the climate is wet in the summer, this situation is even more serious. In June 2000, a composite wooden floor near the bathroom in Wangjing Community, Chaoyang District, Beijing, was arched. After the inspectors opened the floor, they found that the cement mortar on the ground was used by the construction team to tile the bathroom, and it was still wet. of. Therefore, if you decide to lay the composite wood floor during the decoration, you have to stare at the decoration team. It is best to find an empty space outside the house to mix the cement. Don't be afraid of trouble, or you can only clean up yourself if you leave a mess.
According to the China Timber Distribution Association Floor Committee, one of the biggest complaints from consumers is that the composite wooden floor is going to tremble. Experts tell us that the main reason for the floor tremor is that the ground foundation is not flat, which will greatly shorten the service life of the wooden floor. According to the regulations, the straight line distance is less than 2m, and the difference between the highest and lowest points on the ground cannot be greater than 3mm. However, due to the quality and decoration of the building itself, the unevenness of the foundation is widespread. The solution is to shovel excess cement and level with a plaster binder plus 30% sand.
In addition to the above points, there are still many misunderstandings in the consumption of composite wood flooring. Therefore, consumers should know as much knowledge as possible before installation, and be a mature and rational consumer, so that the composite wood flooring can truly give you home. Add warmth and comfort.
