Panel of Experts:
Hello! Recently, the floor of my home has appeared to be uplifted, loose, and the gap is getting bigger. After the factory inspection, it was said that it was forgot to glue when it was installed. The current treatment method is to change the lock floor without using glue. However, when I bought the floor, the shopping guide clearly stated that the lock floor does not need to be sealed. So I have some doubts about whether the manufacturer's approach can't solve the problem fundamentally. In addition, many furniture at home can't be moved now. If the floor under the furniture is not replaced, will it have adverse effects on subsequent use? Please give pointers. Reader Mr. Chen
Locking floor selection
When buying a floor, we usually hear the introduction of shopping guide, single lock, triple lock, etc. Which one is more solid?
Wang Jun said that in fact, no matter what kind of lock form, the gap between them is not big. Whether the lock floor bite well or not depends mainly on the installation level. In addition, from the material point of view, choose the lock floor, in general, the solid wood composite floor or laminate flooring is better, because the two materials are relatively stable. If you choose solid wood lock floor, it is best to choose solid wood, or special treatment, such as carbonization, beeswax sealing, etc., to strengthen the stability of the wood, or to reduce the possibility of moisture. . Solid wood flooring without special treatment is not suitable for use in the case of a wide range of environmental humidity changes.
The cause of lifting is not related to glue
Wang Jun, an expert member of the China Forest Products Industry Association and director of the Forest Products Inspection Center (Changchun) of the State Forestry Administration, said that the reason for the lifting can not be attributed to the glue, and even if the lock floor is glued, there may be a problem of lifting, the manufacturer’s statement Very unscientific.
Wang Jun explained that all the wooden floors, including the lock floor, the main reason for the lifting is that the installation technology is not good or the installation environment is too humid. However, the main reason is due to the humidity. If the humidity in the room is too high or the household often wipes the floor with a damp cloth, etc., the floor will be irregularly expanded and warped. Therefore, if the problem of large humidity is not fundamentally solved and the installation technology is improved, no matter what kind of lock floor is changed, the lifting phenomenon may occur.
There is no lock without a lock
As for Mr. Chen’s question about whether the lock floor should be glued, the reporter also investigated the market. Among the several flooring brands visited by the reporters, almost all of the shopping guides indicated that it is no longer necessary to use glue to select the lock floor, so the gap is smaller and more environmentally friendly.
However, Wang Jun said that in fact, the use of glue without the glue required for the installation of the lock floor depends on the situation, and there is no certain rule. The lock can easily control the deformation of the floor. It can be installed without glue, but it is also possible to use glue according to the environment and customer needs.
The difference between using glue or not is that no glue is used. When the wood floor is inflated and contracted, the floor will be deformed less. When the temperature is low, the gap generated by the floor will be averaged between each floor. However, if glue is used for fixing the floor and preventing moisture from being exposed, there may be a situation where the local area is particularly large.
Furniture movement is stressful
Mr. Chen said that the large furniture in the house is not convenient to move, so I don't want to change the floor under the furniture. Wang Jun said that this is not feasible. It is difficult to open the floor from the middle of the room for partial replacement, because removing the floor will destroy the tongue. He advised the owner to move the furniture to one side of the room and then to dismantle it from the other side, which is more convenient than moving the furniture out of the room.
In addition, it is also very important to put the furniture that has been removed from the room on the re-paved floor.
Wang Jun said that there is no fixed value for the time of placing furniture. Under normal circumstances, it is more appropriate to put the furniture after the moisture content of the floor and the environmental balance, but it takes 15 to 20 days. If the user needs to put the furniture as soon as possible, put the furniture on one side of the room after 48 hours of installation of all the floors, after a while, wait for the floor
Adapt to the environment, and then evenly place the furniture, so as to avoid uneven gaps in the floor when the temperature changes.
