What causes the phenomenon of concave tiles on solid wood floors?

On the surface of the wooden floor, the edges of the two edges are rolled upwards to form a concave bend, which resembles a tile, and this deformation is called the deformation of the concave tile of the wooden floor, referred to as the concave tile transformation of the wooden floor. What is the cause of the concave tiles of the wooden floor?

The reason for the change of concave tiles of wood flooring can be analyzed from the principle of wood structure

When the back of the wooden floor is damp, the wood fiber near the back expands the maximum, and the fiber near the upper surface swells slightly, and the fiber expansion at each layer is uneven, resulting in the size of the back of the wood floor becoming the widest, and the change on the top is small, causing the concave tile change. To put it simply, the concave tile change of the wood floor is caused by the high moisture content of the base layer and accessories under the surface wood floor, including the following situations:

1.The moisture of the base layer under the wooden floor is too large, which is greater than the local equilibrium moisture content;

2.The wooden keel is naturally dried, and the undried moisture content is greater than the equilibrium moisture content;

3.The adhesive used in the installation of wood flooring is too diluted, so that the water content of the glue is too large;

4.The raw floor is not dried, only naturally dried, which is greater than the local equilibrium moisture content;

5.The back groove of the wooden floor is too shallow, and the board surface is too wide.

Generally, there is a heavy pressure, or sharp and angular things will be dented when touched, and it is easy to get dents when walking around in high heels, so I hope you are satisfied.

1. This phenomenon is analyzed from the principle of wood structure, wood swelling and dry contraction is the inherent characteristic of wood, the back of the board is damp, the wood fiber near the back is the largest, and the fiber near the upper surface is slightly expanded, and the fiber expansion at each layer is uneven, resulting in the size of the back of the floor becoming the widest, and the upper surface changes slightly, causing the concave tile change, that is, the base layer below the surface floor and the moisture content of the auxiliary materials is too high. years old.

2. The main reason for the phenomenon of concave tile change on solid wood floors is damp, damp deformation, and long-term humid environment, resulting in uneven moisture content of the board.

3. Thermal expansion and cold contraction, the installation is too tight, and there is no reserved expansion joint.

4. There is floor heating, which is caused by floor heating and poor heat dissipation.

Ground moisture-proof treatment method:

1. Generally, "three layers of oil and two felts" (three layers of asphalt and two layers of linoleum paper, and then a layer of cement is smeared on top to prevent the release of harmful gases); The simple way to deal with this is to apply a moisture-proof film.

2. Balance the expansion of the plate through installation: some add a layer of wool floor to the keel, some require wide gaps between the plates, some require traps to be left at the four corners of the room to facilitate moisture release, and some require springs to be provided in the expansion joints of the wall floor, some use aluminum alloy keel, and some adopt the installation method of rail-type wooden floor.

3. Plate moisture-proof treatment method: back plate tongue and groove painting, wax coating, aluminum-platinum coating, plastic coating using nanotechnology, etc.

Summary. Hello, I am glad to answer for you, the answer to what to do about the tile deformation of the solid wood floor is: when the floor is slightly concave, the baseboard near the edge of the tile is disassembled, and the convection is discharged.

When there is an obvious concave tile on the floor, remove the deformed floor, lay it flat, press it with heavy objects, and dry it in the shade. Serious tiles appear on the floor, replace.

Hello, I am glad to answer for you, the answer to what to do if the solid wood floor tile becomes disfigured: when the floor is slightly concave, disassemble the baseboard near the edge of the tile, and drain the tide by convection. When there are obvious concave tiles on the floor, remove the deformed floor, lay it flat, press it with heavy objects, and dry it in the shade.

The floor is badly tiled and replaced with bends.

It's uneven to step on, it's warped on both sides, and it's like this in the whole room.

Is it a problem with the quality of the floor.

Expansion related: In general, the installation of wood flooring is carried out after the rest of the decoration is completed. Ground leveling or ground keel is a crucial step, the ground of the rough house is uneven, and the direct installation of solid wood flooring is easy to produce hollowing, deformation and other phenomena.

Before installing the solid wood wheel, the floor should not only ensure the flatness of the ground, but also ensure that the ground is dry and clean. Keep in mind that solid wood flooring cannot be installed immediately after unpacking, and inspect it to ensure that there is no quality problem before installation. When installing solid wood flooring, we must pay attention to check whether the keel is dry, if the humidity difference is too large, it is easy to accelerate the moisture absorption of solid wood flooring, and the floor will appear arching and paint peeling off after a long time.

Many owners mistakenly think that the smaller the gap between the floor, the better, because the smaller the better. In fact, the gap in the floor will change with the change of temperature and humidity, and the appropriate expansion joint can be left to stretch it to the fullest. When installing the solid wood floor, you can not use the wooden wedge and add iron nails to fix, because the contact surface between the wooden wedge and the iron nail is too small, which will make the nail holding force insufficient, resulting in the loosening of the keel, and when people step on it, it will make a sound.

Kiss right away.

Now what is the solution to it.

Flooring materials are one of the reasons for this, and it can also be caused by inadequate installation.

And there's more. You can readjust the floor or reinstall the floor.

Failure to fully adapt to the temperature and humidity of the room prior to installation, or uneven or flawed floor foundations, can cause the floor to deform.

Mopped the ground a few times, does it have an impact.

Floor surfaces that are not adequately protected or cleaned daily, and improper maintenance can also cause floor wear and deformation.

Now let's take a look at the baseboard?

Yes, kiss.

Laying wooden floors at home may encounter tile changes, tile changes are a common problem in the use of wood floors, usually reflected in the solid wood floor, so what is the reason for the tile change of the wood floor, what to do if the wood floor has tile change, let's take a look.

1. What is the reason for the tile change of the wooden floor?

The surface of the wooden floor is uneven, and the edges of the two edges are rolled upwards to form a concave bend, similar to a tile, and this deformation problem is called tile change, and the cause of tile change is generally related to moisture, and there are the following reasons.

1. The ground is wet, and the moisture content is higher than that of the floor. The new buildings, the moisture of the ground is generally more than 20, some as high as 25, many buildings are decorated when the construction is delivered, and the ground moisture content is difficult to meet the requirements; The ground is adjacent to the soil, the basement.

2. Do not use moisture-proof mulch, dampen mulch film is damaged or the laying method is incorrect, resulting in the water vapor on the ground channeling to the back of the floor.

3. Water seepage, running water, flooding: (kitchen, bathroom, balcony) water seepage, faucet is not turned off, sewer is not open and flooded, flower pots, trays, fish tanks are flooded, pipes are ruptured, rainwater, etc.

4. Improper use: When cleaning frequently, the mop drips water and seeps under the floor. When cleaning floors, try to mop the floor with a drip-free wet mop.

5. There is not enough extensive finger shrinkage joint left on the side of the wall or fixed obstacles; There are gaskets and sundries in the shrinkage joint; Large furniture or heavy objects are placed symmetrically on the floor, causing the floor to not shrink properly.

6. The ambient humidity does not meet the requirements of use.

7. The indoor is uninhabited for a long time, and the floor is damp due to poor air circulation.

8. The heating rate of floor heating is too fast or the temperature setting is too high.

Second, what to do if the floor is tiled.

1. Trace deformation: The skirting board should be removed immediately at the floor where the tile is changed, so that the convection under the floor can be caused and the moisture will be photographed, so that the board surface will slowly recover with the evaporation of the tide.

2. When the deformation is serious: immediately remove the tile and change the floor, put it flat in the shade for ventilation (not suitable for exposure to the sun and blowing), and add a flat weight on the floor to make it return to normal.

3. When the curvature exceeds 1%, the floor should be replaced with serious tiles.

The above is what is the reason for the tile change of the wooden floor, what to do about the tile change phenomenon of the wooden floor, I hope it can help you understand the relevant knowledge of the tile change of the wood floor, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention!

1.If the shape of the solid wood floor tile changes slightly: the solid wood floor that causes the tile change should be removed immediately, so that the convection under the solid wood floor is caused, the moisture is removed, and the solid wood floor surface slowly recovers the level with the evaporation of moisture.

2.If the shape of the solid wood floor tile changes seriously: if the tile becomes more serious, the tile should be removed immediately to change to the solid wood floor, square in the shade for ventilation (not suitable for exposure to the sun and blowing), and add a flat weight on the solid wood floor to make the solid wood floor return to normal.

3.If the bending deflection of each solid wood floor tile exceeds 1%, each solid wood floor with serious tile deterioration should be replaced.

4.If the solid wood floor is soaked in water in a large area, the after-sales service office of the wood floor should be notified in time, the solid wood floor should be carefully pried up, and the water on the surface of the solid wood floor should be wiped dry as soon as possible, and then placed in the shape of "well" to prevent deformation by using the weight generated by the stacking. When placing the solid wood floor, pay attention to the reverse side of the solid wood floor to prevent the surface from drying out due to rapid drying, and at the same time pay attention to not being exposed to the sun, it should be placed in a ventilated place to dry, one to two weeks later, depending on its recovery, and then decide whether it can be used again.

Once installed, you can't handle it.

Either continue to use it, or tear it down and replace it.

Wood is an anisotropic material, the fibers of wood are arranged longitudinally, wood is a porous substance under the microscope, many ducts are arranged longitudinally, the longitudinal deformation of wood is the smallest, and the conduction speed of moisture is the fastest; The width of the wood is deformed (radial and chordal) and the moisture conduction is very slow.

The shingle-like deformation of the solid wood floor can be solved by the correct pavement method, and there are three parts of moisture that can cause the shingle-like deformation of the solid wood floor: 1. The moisture in the air; 2. Water in the keel; 3. Moisture in the ground. In the process of laying the floor, whether it can effectively prevent these three parts of moisture from contacting the back of the floor is the key.

The frequent mistakes in paving are as follows: 1. The paved floor is not equipped with moisture-proof film (the three parts of the moisture are not prevented); 2. The connection of the moisture-proof film is not sticky or not strictly sticky, breathable, and cannot achieve the purpose of moisture-proof; 3. The moisture-proof film is spread under the keel, which only prevents the effect of ground moisture; 4. Spread the moisture-proof film on the keel, the moisture-proof film is wavy on the keel, and there is a gap between the floor back plate and the moisture-proof film, and the three parts of the moisture can still penetrate in, resulting in the deformation of the floor tile; 5. The reserved gap between the floor strips is not scientific, and many paving instructions only write a reserved gap, in fact, the size of the reserved gap on the floor should be based on the actual moisture content of the floor. Shrinkage coefficient of tree species.

The width of the floor. Factors such as the equilibrium moisture content of the region reasonably reserve gaps. If you want to block moisture from contacting the back of the floor, the moisture-proof film must be in close contact with the floor backing to ensure that the moisture-proof film is in close contact with the floor backing.
