2022-09-29

The problem of tile-like deformation of solid wood floors, because the problem of tile-like deformation of solid wood floors has not been solved in many places, the problem of tile-like deformation of solid wood floors still occupies a large proportion of complaints of solid wood floors, so it is necessary to deal with solid wood floors. The causes of tile-like deformation are analyzed in detail, and preventive measures are proposed to reduce and avoid the occurrence of such problems. Moisture causing shingles

The moisture that causes the tile-like deformation of the floor has the following three parts:
1 Moisture of the ground

For newly-constructed buildings, the moisture content of the ground is generally above 20%, and some are as high as 25%. The national standard stipulates that the moisture content of the ground should be less than 20% before installing the floor. Many buildings are decorated in the same year, and the moisture content of the ground is very difficult. Meet the requirements. Even if the moisture content of the ground is below 20%, a large amount of moisture will run out.

2 Moisture of wooden keel

At present, the wooden keels used in many areas of our country are not dried, and most of them rely on natural drying, and the individual moisture content is above 20%. The wooden keels used in the northeast are almost never dried, and the moisture in the wooden keels can also cause the floor moisture. Increase in height, resulting in tile-like deformation.

3 Moisture in the air

The air in southern my country is humid. In the rainy season, the relative humidity of the air can reach more than 95%, and the equilibrium moisture content of the air can reach up to about 18%. Even in the northeast and north of China, in the rainy season from June to September, the air balance The moisture content can be up to more than 15%. If the moisture content of the floor is lower than the local equilibrium moisture content, the floor can still absorb moisture.

Frequently asked questions about floor installation
1 Paving the floor without adding moisture-proof film

During the installation process of the floor, no moisture-proof film or no moisture-proof measures are taken. If it is an old building, the environment is not humid, the wooden keel has been dried, and the moisture content of the floor is similar to the equilibrium moisture content of the environment, and the floor will not appear tile-like deformation. . In any case, this installation method has no effect on the moisture on the ground, the moisture in the keel and the moisture in the air. When any kind of moisture exceeds the moisture content of the floor, the floor will be deformed like a tile. This method is extremely ineffective. safe. It also does not meet the requirements of GB/T 20238-2006 wood floor paving, acceptance and use specifications.

The correct installation method of solid wood floor
According to the test results and the analysis of the problems in the commonly used solid wood floor installation methods, we found that the best way to solve the tile-like deformation is to block the moisture from contacting the back of the floor. Layer the substrate, hold the moisture-proof film, and ensure that the moisture-proof film is in close contact with the back of the floor. In this way, the moisture in the ground, wooden keel and air can be effectively blocked from entering the floor from the back of the floor, and the problem of tile-like deformation of the solid wood floor (the bamboo floor is also adapted) can be completely solved. Therefore, in the newly promulgated national standard GB/T20238-2006 Specifications for Paving, Acceptance and Use of Wooden Floors, only the installation method of the wooden keel of solid wood floors is specified. The following is an excerpt of the main content of the installation method of solid wood flooring in the standard as follows (see the standard for details):

1 Flooring should be carried out after the concealed ground works, ceiling works, wall works, water and electricity works are completed and accepted.

2 Ground flatness, use a 2m ruler to test the ground flatness, and the maximum chord height between the ruler and the ground should be ≤5mm. The ground moisture content should be less than 20%, otherwise moisture-proof treatment should be carried out.

3 It is strictly forbidden to use materials that exceed the national mandatory standards.

4 The moisture content of wood keel, dunnage and other wood used for paving shall comply with the provisions in 6.4 of GB/T 15036.1-2001. The wood keel should use wood with good nail-holding strength and certain corrosion resistance or wood treated with insect repellent. Wooden keel thickness ≥ 25mm, width ≥ 35mm.

5 Plywood, blockboard and particleboard and other man-made boards can be used for the wool floor. The wool floor should meet the quality requirements of the corresponding national standards.

6 According to the length of the wooden keel, reasonably arrange the position of the fixed wooden keel; the drilling distance is less than or equal to 300mm, and the hole depth is less than or equal to 60mm, so as not to penetrate the floor; Larger than the diameter of the hammer drill.

7 When there is a gap between the wooden keel and the ground, use the anti-corrosion and hard material to cushion it. If the wooden keel is not flat, it should be flattened or flattened. When the wooden keel is installed, the tolerance of the distance between the wooden keel is ≤5mm, the flatness is ≤3mm/2m, and the expansion joint between the wooden keel and the wall is (8~12)mm.

8 Nail-fur floor can be laid on the wooden keel, and the use of the entire fur floor is strictly prohibited. The gap between the rough floor paving is 5-10mm, and the distance between the wall and ground attachments is 8-12mm. The fur floor and the wooden keel shall be fixed with nails at 30° or 45°, and the distance between the nails shall be less than 350mm. After fixing, there is no abnormal noise and obvious subsidence. The paving of the rough floor should be level, and the flatness should be ≤3mm/2m.

9 Lay moisture-proof film (plastic film), the joints of the moisture-proof film should be overlapped by more than 50mm and firmly bonded with tape, and the corners of the wall should be turned up by 50mm.

10. Drill eyelets at the groove and mouth of the floor. The hole diameter of the eyelets should be slightly smaller than the diameter of the floor nails. Use the floor nails to fix the floor from the eyelets. Floors should be staggered. The length of the floor nails should be 2.5 times the thickness of the plate, and the nails should be inclined at an angle of 30° to 50° from the groove and mouth when fixing.

11 The splicing gap of the floor should be reasonably determined according to the environmental temperature and humidity conditions of the paving, the width of the floor, the moisture content of the floor, the properties of the wood and the laying area.

12. The connection between the floor and other floor materials should be partitioned (gap ≥8mm) and approved by the user. The buckle transition should be installed firmly.

13 When the laying length in the width direction of the floor is greater than or equal to 6m, or when the laying length in the length direction of the floor is greater than or equal to 15m, expansion joints should be set at appropriate positions and transitions should be made with buckle strips. Near the door, expansion joints should be set up, and buckles should be used for transition, and the buckles should be installed firmly.

14 After the paving is completed, the paving personnel shall comprehensively clean the construction site, and comprehensively check the paving quality of the floor. After confirming that there is no paving defect, the user can be required to sign the paving acceptance form for confirmation.

Whether the characteristics of wood flooring are really understood

We all know that laminate flooring is cheap, solid wood composite flooring is cost-effective, solid wood flooring is natural and environmentally friendly, feet are comfortable, bamboo wood flooring is warm in winter and cool in summer, it can be said that each type of floor has its own characteristics, but do you really understand these wooden floors? Let's take a look at the characteristics of various wooden floors. First of all, we have to say that the solid wood composite floor, the general solid wood composite floor is mainly divided into three categories: three-layer solid wood composite flooring, multi-layer solid wood composite flooring and new solid wood composite flooring. First of all, the next three-layer solid wood composite floor, as the name of the three-layer solid wood composite flooring is made of three different wood bonding, the surface layer is mainly made of birch, beech, oak cherry wood and ash and other hard wood. The middle layer mainly uses some cork materials such as pine, and its elasticity is relatively good and the price is relatively low, so it is cost-effective. Multi-layer solid wood composite flooring is mainly based on multi-layer plywood as the plate substrate, and the surface layer is inlaid with hardwood sheet, which is laminated by urea-formaldehyde resin glue. The new solid wood composite floor, the surface layer of hardwood is basically the same as the first one, the middle layer and the bottom layer use medium density fiberboard or high-density fiberboard, and its effect and durability are similar to the three-layer solid wood floor. Solid wood flooring can be divided into hardwood flooring and cork flooring: among them, hardwood flooring has the characteristics of hard texture, fine texture, good wear resistance, elasticity, dryness, cleanliness and beauty, etc. The wood used is ash, birch, walnut wood and beech wood and other high-grade wood, and cherry, longan and camphor are also used. Cork flooring is divided into cork, hemlock and so on. Made of snow and cypress, the warmth is more elastic. However, the wear resistance is worse than the cork floor, if the wood is not thoroughly dried, it is easy to deform, cracking and so on. In general, the characteristics of wood flooring vary widely, and how to choose a satisfactory wooden floor is an important step to enjoy the home life healthily.

In daily life, some potential factors will affect the service life of wood flooring and the overall quality of home decoration. Today, China Flooring Network has collected seven killers of wooden flooring for everyone, and I hope that everyone will try to avoid the damage of these factors in daily life. First, water: due to the natural characteristics of wood, it will swell when it encounters water and moisture. Second, light: wood flooring because of the nature of the wood itself, can not be exposed to sunlight or ultraviolet rays for a long time, if necessary, use curtains and other shading things to shade. Third, furniture weight: furniture, dining table, chair when moving or using roller chairs, easy to cause floor scratches. It should be gently held and protected by upholstery on furniture, tables and chair feet to extend the service life of the floor. Fourth, high temperature items: try to avoid placing the heater or other heating appliances directly on the floor. Fifth, insects: the floor in the production process due to high temperature, high pressure will not have termites, but may be due to the construction of the environment itself and cause the phenomenon of external insects and ants coming in, if such a thing occurs please use insecticide spray to remove insects. Sixth, corrosive agent: avoid the use of various chemicals on the floor, such as accidentally spilled on the floor, please wipe as soon as possible. Seven, chemicals: such as the floor is contaminated by hair dyes, shoe polish and other solutions, it is difficult to remove. Avoid wiping the floor with chemical reagents, otherwise the floor will become white. If the wet chemical rag is placed on the floor for a long time, it is easy to cause discoloration of the floor.


The floor is the background color of the home, and the lines of furniture and other soft decoration details determine the style. Therefore, the color selection of home wood flooring is very important. First, the light is poor, the place is small Properly light color, less pattern, preferably high-gloss floor. This kind of floor is the savior of small apartments, and the secret of small apartments is to blur the boundaries between ceilings, walls, and floors. The closer the colors, the better the blur effect. The safest option is to have as little white or yellowish pattern as possible. If the light in your home is not good, remember to buy a smooth surface, one meter of sunlight scattered into two meters, the happiness is absolutely appreciated. As for orange, brownish gray, and dark red, they are not very suitable. Second, the light is good, the area is large. If your home is a transparent large flat floor, an old bungalow in the concession, and more than 90 square meters full of sunshine, the above colors that have been shot can be picked up. But if you don't have any artistic cells and are half-aware of various styles, or if you only plan to buy a house for a few years to sell, then you can choose the lazy universal solution: use wild colors! The wild color is the pale yellow color in the picture above. Because of the large space, you can choose to wear a delicate pattern, a nude wood scar, or such a striped stitching color. A pinkish or darker yellow color will do. Just like most of the basic models of MUJI, remove the furniture inside, this is also a high-quality basic interior of the original, this neutral color, almost can be matched with any style of home. If your home is particularly well-lit and the layer height is particularly good, you can also choose other neutral colors with darker colors on the basis of this yellow. In general, the darker the color, the more advanced it is, but it must not be premised on sacrificing the sense of space. Third, no matter what color floor is used, it is best to use white skirting boards. Especially if your home is small, remember not to use the same color as the floor. Especially in apartments, footliners of the same color as the floor will visually lower the height of the floor. It's best to use white door covers – no matter what color furniture and doors you use. LOFT and villas can be drugged, but it is a more secure practice to use white footliners for apartments. Fourth, about the color selection of some large pieces of furniture A good way to do this is to pick the floor, put on a color swatch and compare it with the furniture. It is best to buy a large brand of flooring, the quality is on the one hand, on the other hand, it can avoid the color goods are not in the right version. There is a more general principle of collocation principle: large pieces of furniture, especially a flat piece of furniture, such as a table, including the open kitchen table, coffee table, sideboard, etc., the color of this plane is best either similar to the ground, or similar to the wall.


Everyone who loves the family likes to clean the room a new look, but many times do not know how to do more with less, not washing brush can be, sometimes cleaning the room is also a fine work, the floor is a good example, the correct scrubbing is very exquisite. Now many families use wooden flooring, but the floor is not so new after a period of time, the reason is that many people only know to use a mop when wiping the floor, or use a rag to wipe, and do not know much about the maintenance of the floor. Whether it is laminate wood flooring or oil-wax solid wood flooring, it is very taboo to wipe directly with a wet mop when cleaning, and it should be cleaned with a special cleaning agent for wooden flooring, so that the floor maintains its natural primary color and can prevent the wood board from cracking and cracking. In order to avoid excessive moisture infiltrating into the wooden floor, when using floor cleaners, minimize excess moisture and wring out the mop. When waxing the wooden floor, it is best to choose a spray waxing agent, which is easy to beat the wax evenly. Then wipe off the excess oil with a soft cloth to avoid bright spots. Waxed floors should not be used in a hurry and should be air-dried naturally at night. If you want to avoid long-term stampede wear on the floor, always keep the gloss and bright, after the floor is cleaned, you can also apply a layer of wood floor wax maintenance agent. In addition, to remove black rubber wear marks or other stains on the wooden floor that cannot be removed with water, wipe off with a soft cloth dipped in low-concentration alcohol or a little liquor.


Nowadays, many families will choose to lay solid wood floors when doing ground decoration, but solid wood flooring will always look a little color difference, in fact, there are many reasons for the color difference of solid wood flooring, mostly because of the different types of trees, origin, color, and grain, we do not need to tangle, basically as long as the solid wood floor will have a certain color difference. There are many reasons why solid wood flooring has color, not only related to the location of the wood used, but also related to the processing method. In the wood, there is a certain difference between the treetops and the roots, many solid wood floors are made of tree roots, but there are also some of them made of wood on the treetops, in general, the closer to the root of the tree, the darker the color, so the root and the treetop oil has a big color gap. Wood is also related to the bark and the heart of the tree, generally the closer the wood is to the center of the tree, its material will be heavier and denser, the color is also deeper, close to the outer bark is just the opposite. The processing method used in the processing process of solid wood flooring will also produce a certain degree of error, the method of opening the board when using wood is different, there are strip cutting and chord cutting, after different ways of processing the floor grain will be different, different grains of the two pieces of the floor will inevitably show color difference visually. In the process of making solid wood flooring color separation technology will also lead to a certain error, in the solid wood flooring in the primary color plate, the natural color swatch is not separated from the color number, after brushing the paint color difference will be more obvious, so usually the specification manufacturers will be in the paint after the wood board will be separated in the factory, according to the different timber will be divided into two or three color numbers, many factories have strict requirements for color difference, color separation work is strictly controlled, such a floor color difference will be small. In fact, in the decoration will also produce errors, if the decoration master did not compare the color of the floor before laying, directly and randomly laying, such a color difference will be very serious, the color of the floor is laid together, you will find that the error will be much smaller. Environmental problems will also cause color difference, generally close to the window we will find that the color of the floor is brighter than the color of the floor in a dark place, which is caused by the influence of sunlight. Many people will have this kind of question, think that the floor color difference is caused by quality problems? Usually, there are not many cases of color difference in laminate flooring itself, and color difference for solid wood flooring cannot be prevented. The chromatic aberration of the solid wood floor is determined by its own characteristics. There are more holes in the wood, not the same, some raw materials are dense, so the absorption of light and the depth of the paint are different, so sometimes the color of the same floor at both ends will show shades and different lines, and the subtle floor color difference is not due to quality doubts.


The problem of tile-like deformation of solid wood floors, because the problem of tile-like deformation of solid wood floors has not been solved in many places, the problem of tile-like deformation of solid wood floors still occupies a large proportion of complaints of solid wood floors, so it is necessary to deal with solid wood floors. The causes of tile-like deformation are analyzed in detail, and preventive measures are proposed to reduce and avoid the occurrence of such problems. Moisture causing shingles


In modern home decoration, many families like the laying of the ground. The original wooden floor is a wooden floor directly processed by using solid wood as a raw material. The style returns to the original and the texture is natural. It has the texture of the natural growth of wood and is a poor conductor of heat. It can play the function of warm in winter and cool in summer, with comfortable foot feeling and safe use. It is an ideal material for floor decoration such as living room, study and bedroom. Next, we will introduce whether the original wood floor is good or not.
