Frequently Asked Questions after Parquet Installation
Parquet has both the stability of the laminate flooring and the aesthetics of the solid wood flooring, and it has environmental advantages. But sometimes there will be some problems after the parquet pavement, Jiu Zheng Xiaobian bring you to understand some common problems and their corresponding measures. 1. Why does the color change occur after the parquet is paved? The discoloration of wood is mainly caused by the absorption of ultraviolet light. The sapwood and the heartwood of the wood absorb the ultraviolet light and discolor to a different extent, which may cause a certain color difference in the paved floor. The surface of the multi-layer parquet is natural wood, which has the natural properties of wood. The photochromism produced is a normal phenomenon and is not a product quality problem. The discoloration reaction of most woods is from shallow to deep, and only a few woods are deep and light, and the discoloration on the same floor is basically the same. Therefore, the floor after paving should not be exposed to the sun for a long time, and the necessary shading measures should be taken as appropriate. External factors affect: In some complaints, except for normal photochromism, most of them are in the geothermal environment. Before the geothermal floor paving, the moisture content of most floors is about 20%. During the floor covering process, due to the damage of the moisture-proof membrane, when the geothermal heating is carried out, a large amount of moisture will break into the floor from the damaged part, resulting in a sharp increase in the moisture content of the floor. The dissolution of some soluble substances and the action of some color-changing bacteria cause the wood to deteriorate. In some cases, in wet areas such as bathrooms and kitchens, the effects of external moist moisture can also cause discoloration of the floor in local areas. The discoloration of the above-mentioned floor is generated in the damp area of ​​the floor, and the interface between the discolored area and the non-discolored area is very obvious, and is continuously distributed among several floors. Causes: 1 The ground is not flat, there is a small pit bag with unevenness. After the floor is paved, the moisture-proof film is broken, causing ventilation. Take measures to level the floor before installing the floor. 2 When paving, there are sand on the ground, which is not cleaned, and the moisture-proof membrane is broken to cause ventilation. The measure is to clean the floor before paving. 3 When the pavement is installed, the joint of the moisture-proof membrane is not sticky, resulting in ventilation. The moisture-proof film should be adhered to the tape, preferably with a plastic tape with a width of 60 mm or more to ensure that the moisture-proof film is airtight. 4Electrical heating is used in some areas. Because the electricity fee is based on peak, valley and flat charging methods, that is, half price (valley) of electricity after 12 o'clock in the evening, many users turn off the switch during the day and turn on the electric heating equipment after 12 o'clock in the evening. The indoor temperature is adjusted to 27 ~ 30 ° C, the surface temperature reaches nearly 100 ° C in a short time, resulting in damage to the moisture-proof membrane, resulting in ventilation, discoloration and deformation of the floor. This violates the requirements of geothermal heating (surface temperature control is around 40 °C). It is recommended that the user should change to 24-hour continuous heating. Otherwise, the user should be responsible for the discoloration. 5 When the floor is paved to the interface with the wet interface, such as: bathroom, kitchen, shaded balcony, etc., the moisture-proof film should be returned upwards, and the edge of the floor should be covered with a moisture-proof film to prevent moisture from entering, reducing and avoiding the floor in the area. Discoloration and deformation. Second, why do you have a large gap after the multi-layer solid wood composite floor pavement? The multi-layer solid wood composite floor has the smallest deformation in many floors, and the deformation amount is only about 1/20 of the maximum deformation of the solid wood floor string cutting material, and no large gap should be generated after the paving. In general, the maximum expansion and contraction of a single 125mm wide floor in the north will not exceed 0.2mm. After proper paving, the actual moisture content of the summer floor in the northern region is 12% to 13%, the dry and hot environment in winter (about 30% relative humidity), and the moisture content of the floor is 6% to 7%. In the geothermal environment, the final equilibrium moisture content of the floor is 4% to 5%. That is to say, the moisture content after the floor pavement is 12% to 13% in the summer (rainy season), and the floor is in the largest physical state. If the floor is a rubber suspension suspension, the floor of the room is formed as a whole, and when the moisture content changes, the floor of the room expands and contracts as a whole. At this time, if the room is symmetrically placed on the sides of the room, heavier furniture. When the winter is coming, the room is relatively dry, and the floor will inevitably shrink. Due to the heavy objects on both sides, it will inevitably cause the individual parts of the floor in the middle of the room to open, and the accumulated dry shrinkage will be concentrated in one or several gaps, resulting in a larger floor. Gap. If the edge of the floor is not glued, the standard room of 3 ~ 4m wide, under the geothermal environment conditions, the entire floor shrinkage of the room floor is less than 5mm, and the maximum shrinkage of each floor is less than 0.2mm, which is difficult to see with the naked eye. No glue is easy to repair, and the gap can be evenly distributed. To prevent the floor from swaying, a spring can be used between the floor and the wall. No matter how the furniture is placed. In addition, although the multi-layer solid wood composite floor has small deformation, the structure determines the length and width direction of the multi-layer solid wood composite floor. Generally speaking, the floor length is more than 8 times the width. Under the same conditions, the deformation in the length direction is also the width. The multiple relationship of deformation, therefore, the multi-layer parquet floor gap is larger than the side gap is also normal. Third, why does the multi-layer solid wood composite floor paving sound? Most of the multi-layer parquets are laid directly on the ground. The reason for the sound after the floor is that the people move on the floor, the floor moves up and down, the sides and sides of the floor and the tongue and the tongue and groove The sound produced by the friction between the two. The up and down movement of the floor is the main factor. In many cases, the floor is not completely laid out, and the sound is generated after a period of use or paving. When we received complaints, the focus of many people's controversy was that the floor was loose (the gap between the tongue and the gutter was too large). If it is really loose, why is the floor just not finished, and it will not sound until after a while. Even the loose floor we lay it on the flat marble floor, no matter how we walk on the floor, there is no sound, because the floor is in close contact with the ground, the floor does not move up and down when people walk, the floor There is no relative movement between the side and the side, between the tongue and the tongue and groove. Without friction, the sound naturally does not exist. Therefore, to solve the problem of sound after the floor covering, the key is to solve the problem that people do not move up and down during the stepping on the floor.
