What is the general cause of bulging joints on the wooden floor at home?

Floor surface improvementDuring installation, it is sometimes inevitable that the joints are not completely filled with glue. If the mop drips water when mopping, it will cause water to surface the floor, which will enter through the joints with less starching, and the floor substrate will absorb water, causing local expansion and blistering.

The surface phenomenon is that the shape of the joints is more uniform, the place near the water source is more serious, and the far place is getting flatter and flatter. Such problems occur in places close to restrooms, kitchens, heating ducts, air conditioning condensate outlets, windows, etc.

If the water immersion time is long and the surface phenomenon is no longer obvious, you can open the floor to check whether there is a watermark to determine the cause.

Bulging of short joints in the floor, which is manifested as a bulge in every short side of the long floor, is usually caused by too much moisture in the floor. The higher the bulge, the greater the moisture on the ground.

If the soaking time is long and the surface phenomenon is no longer obvious, you can open the floor to check whether there is a watermark to determine the cause of the floor short seam bulging, indicating that every short seam of the long floor is bulging, which is usually caused by too much moisture on the ground. The higher the bulge, the greater the moisture on the ground. Second, the floor is bulging.

The manifestation phenomenon is that there is a sense of levitation when stepping on it, and it will be more serious in some places.

When the expansion joint is not reserved enough to make the floor arch the room paved with more than two rooms, the buckle is not installed on the door cover. When moisture and moisture are high, the floors of the two rooms extend horizontally, causing the room doorways to implicate each other, and the floor arches expansion joints with baseboards or filled with plaster putty, etc. The floor cannot be stretched, resulting in foreign objects remaining under the floor during the arching installation process, resulting in the base under the bulging floor being arched.

For example, before the flooring was installed, there was a solid wood floor on the original floor.

After the floor was installed, the original floor arched due to moisture, causing the floor to arch. Extended material maintenance program If the joints bulge, repair the solution to replace the floor. If it is the cause of the arching of the floor, the maintenance plan, remove the baseboard, re-reserve the expansion joints, install the buckles at the joints between the rooms, reinstall the baseboards, clean the gypsum putty and other reserved expansion joints, open the floor and reinstall, remove the floor, treat the floor flat, dry it and then lay the floor.

If the joints of the wooden floor are bulging, it is usually because water is poured into the hole from this gap, causing the water inside to swell and the wooden floor has been deformed.

But because the home is too damp, it may be that the gap left is too small, and there may be a lot of mopping in the house, so don't use hot water to mop it.

It may be due to the dampness of the weather, or the moisture becomes inflated, or it may be that the reserved gap is too small, so it will cause the wooden floor to bulge.

1. Swelling due to moisture.

Due to the humid weather, the floor can easily become swollen due to moisture in the air; When using water, the water is accidentally in contact with the floor for a long time, causing the wooden floor to swell; Before laying the floor, the substrate is not dried, or the waterproofing layer of the substrate is not done well, which causes the moisture of the substrate to affect the wooden floor.

2. The reserved gap is too small.

When laying wooden floors, there should be a certain amount of gap between each plank, because the plank will expand and contract due to various factors. Some owners will ask the construction team to make the seams as small as possible for the sake of aesthetics. In fact, once the plank expands, it will bulge, so there must be a certain amount of gap when laying the wooden floor.

3. The large area of wooden flooring is not laid in sections;

The flooring of several areas of a room is laid together without the use of guselsticks; The floor was not thoroughly cleaned before installation, leaving some foreign objects on the ground; The base of the floor bulges itself; Usually the maintenance of the wooden floor is not proper enough; These are all causes of bulging wooden floors.

If you want to avoid bulging floors, do the following:

1. Ensure the dryness of the ground when laying.

2. The moisture content of the board is kept at 12%.

3. When laying the floor, leave a certain gap for the expansion and contraction of the floor.

4. If it is a large area of floor laying, be sure to pay attention to segmentation.

5. Clean the floor before laying the floor.

So what should I do if the floor has been bulging?

1. If the situation is not too serious, you can disassemble the drum and the surrounding floor to disperse the damp gas underground. If it is a little more serious, you can disassemble the floor in a large area to make the base and keel fully ventilated and dry, and then lay the floor back again. When laying back, remember to leave some space for the expansion and contraction of the plank itself.

Second, if it is due to the fact that the original expansion joints are blocked by some debris. Some tools can be used to clean the debris in the expansion joint, so that the bulging situation will be alleviated.

3. If the floor has been deformed and damaged, the deformed floor should be removed and a new wooden floor should be installed.

1. On-site inspection.

Sports wood floor maintenance staff, or stadium staff, when they find that the sports wood floor is soaked in water after work, don't panic first, be calm. Inspect the soaking site at the first time to eliminate potential safety hazards, such as whether there are wires, electrical appliances, flammable and explosive materials on the soaking floor, etc.

Then according to the degree of water immersion of the sports wood floor, a solution is formulated.

2. Soak in water lightly.

If the sports wood floor is lightly soaked, the lightly soaked and damp floor can be wiped dry and ventilated. If necessary, disassemble the sports wood floor to observe whether there is water on the ground and observe whether the floor is obviously deformed. If so, it needs to be removed and dried, and reinstalled.

3. Heavy soaking.

Sports wood flooring that is seriously damp or soaked in water for 30 minutes will be deformed, expanded, and lost its luster. Such sports wood flooring is basically scrapped and should be replaced, and attention should be paid to removing the moisture under the floor and drying it.

4. Precautions.

After the sports wood floor is soaked in water, it is important to pay attention to the fact that it cannot be blown by hair dryer, exposed to sunlight, or dried, which will accelerate the serious deformation and damage to the surface of the sports wood floor of the basketball hall.

1. Cutting and repairing, if there is no reserved expansion joint when laying the wooden floor, it is easy to warp, at this time, it needs to be cut, and the expansion joint can be cut to solve the floor warping; Drying and repairing, the wooden floor is in a damp state for a long time, it will be warped, at this time it needs to be removed, placed in a cool place to dry, the ground and floor degree to dry, and then re-paved.

2. If there is a local upward arch on the surface of the wooden floor, it is very likely that there is too much moisture in the air, and the wooden floor will absorb the moisture in the air for a long time in this environment, and then expand and arch, which will also appear in the house that has been vacant for a long time. If the moisture content in the base concrete is high, it will also expand and arch when the moisture-proof isolation layer is not well sealed.

Summary. 1. Clean up the expansion gapFor the arching problem caused by the expansion gap being blocked, so that the wooden floor cannot be stretched, it is necessary to clean up the wood chips, debris and other debris in the gap in time to restore its expansion space. 2. If the arching floor is caused by serious local water soaking, the arching of the wooden floor can be removed by a professional pavement master, clean up the water stains, and air dry the wooden floor.

If the deformation of the floor is not particularly serious, the skirting around the floor can be disassembled to release the moisture from the ground, and with the help of air conditioning to dehumidify, the arching area will slowly return to its original shape.

My wooden floor is bulging, how can I remedy it?

Hello, it is a pleasure to answer your questions, and the solutions I give are as follows.

1. Clean up the expansion gapFor the arching problem caused by the expansion gap being blocked, so that the wooden floor cannot be stretched, it is necessary to clean up the wood chips, debris and other debris in the gap in time to restore its expansion space. 2. If the arching floor is caused by serious local water soaking, the arching of the wooden floor can be removed by a professional pavement master, clean up the water stains, and air dry the wooden floor. If the deformation of the floor is not particularly serious, the skirting around the floor can be disassembled to release the moisture from the ground, and with the help of air conditioning to dehumidify, the arching area will slowly return to its original shape.

There are several reasons for this:

First, the seams are bulging.

1. Progress of the floor surface: During the installation process, it is inevitable that sometimes the glue does not completely fill the joints. If the mop drips while mopping, it will cause water to accumulate on the surface of the floor and enter through the joints with less sizing, and the floor substrate will absorb water, resulting in local expansion and blistering.

In this case, the joints on the surface of the floor are partially bulging;

2. Water inflow and bulging under the floor: the surface phenomenon is that the shape of the seam bulge is more uniform, the place near the water source is heavier and stricter, and the far place is more and more flat. The places where such problems arise are:

Close to restrooms, kitchens, heating pipes, air conditioning condensate outlets, windows, etc. If the water immersion time is long and the surface phenomenon is no longer obvious, you can open the floor to check whether there is a watermark to determine the cause.

3. Drum of short joints on the floor: It is manifested as the bulging of each short seam of the long floor, which is usually caused by too heavy moisture on the ground. The higher the bulge, the greater the moisture on the ground.

Repair program: replacement of the floor.

Second, the arching of the floor: the performance phenomenon is to step on the sense of suspension, and some places will be more serious.

1. The expansion joint is not reserved enough, so that the floor is arched;

2. The room is paved: when the floor is installed in more than two rooms, the door sleeve is not equipped with buckles, and the floor of the two rooms is stretched horizontally when the humidity and moisture are larger, causing the door of the room to pull each other and make the floor arch;

3. The expansion joint is nailed by the baseboard or filled with plaster, putty, etc., so that the floor cannot be stretched, resulting in the arching of the floor;

4. During the installation process, there are foreign objects left under the floor, resulting in arching;

5. The base layer under the floor is arched, such as the original ground has a solid wood floor before the installation of the floor, and the original floor is arched due to the moisture of the original floor after the floor is installed;

Maintenance plan: lift and lower the baseboard and reserve the expansion joint again; Install buckles at the connection between the room and the room; Reinstall the baseboard and clean out the reserved expansion joints such as plaster and putty; Lift the floor and reinstall it; Remove the floor, level the floor, dry it and re-pave it.

Generally, it is caused by the lack of cement when the masonry under the bottom plate.

If it is a solid wood floor, it must be damp, corrected, the floor or wood is not the principle of thermal expansion and cold contraction, solid wood floor is damp expansion, deformation, drying, floor moisture loss contraction, cracking, this is the basic characteristics of solid wood flooring or wood, so your floor is damp when it bulges.

Generally, it is caused by the room water or the floor is soaked for too long, or the air humidity is too large, or it may be caused by the floor installation without leaving expansion joints or too small or the wrong way of reservation.

There are many reasons for the floor bulging, 1. Pavement reasons, when the workers pave, there is not enough expansion gap, which leads to the middle air drum when the floor is hot up.

2. For the reason of their own use, solid wood flooring or solid wood parquet, when cleaning, use a wet mop, and then the wooden floor is damp and rises, and after drying, the air drum is in the process of shrinkage.

3. The moisture-proof floor mat is not paved, the ground is relatively moist during the decoration, the floor is damp 4, and the wooden floor itself is the reason. If the balance layer is not done well, this situation is less likely.

2. If the ground moisture-proof measures are not properly handled, it will also cause the floor to bulge, in the humid ground, if the moisture-proof film connection is not glued with waterproof tape, although the balance layer on the back of the floor is not damaged, the floor has been in a humid environment for a long time, and the moisture may still enter the floor after the balance layer is eroded by moisture, causing damage to the floor.

3. In order to make the floor last longer, we should pay attention to the maintenance of the floor. If the bulging phenomenon caused by water ingress at the ground splicing place (such as: heating running water, large area of water ingress, etc.), it is a problem of improper use and maintenance by users.

Regardless of whether the joints of the solid wood floor or laminate solid wood floor bulge after soaking in water, there is no other remedy except to replace it (which can be replaced as a single piece).

If it is a solid wood floor, the joints are not very serious except for bulging, and the following methods can be used to remedy it, and the floor will slowly recover after it is gradually dry.

1.The surface water on the floor should be blotted dry in the shortest possible time.

2.Quickly remove the baseboard from the floor to expose the expansion joints, which allow the moisture to be dissipated.

3.At the same time, you can also use a vacuum cleaner to absorb water vapor in the splicing gap of the soaked floor, or use a hair dryer to dry it with cold air, but do not use hot air to prevent the surface from drying and cracking due to heat and drying.

It can be replaced with a single floor.

It's laminate flooring. After soaking in water, there will be bubbles, hollowing and other phenomena. The solution can only be to remove the problematic replacement of the same variety of flooring, you can contact the floor installation after-sales or decoration company to replace. It is free of charge during the warranty period.

Paving method. 1. Pavement from left to right or from right to left in turn, groove to the wall, put a wooden wedge between the floor and the wall, leave enough expansion joints, dry areas, the floor is wet, and the expansion joints should be small; In humid areas, the floor is dry, and the expansion joints should be left large. Check the straightness of the floor with the pull line, check with the shop during installation, observe the height difference and gap of the board surface during the trial paving, adjust it at any time, and only after passing the inspection can the sizing installation. Generally, spread on the side 2-3 rows, apply a small amount of D4 or waterless environmental protection glue to fix.

The rest of the middle part is completely meshed by the tenon groove, and there is no need to apply glue.

2. The last row of floors should be cut and glued by measuring its width, and there is a hook or screw top to make it tight.

3. In some particularly humid areas such as East China, South China and Central South China, when installing the floor, the floor is generally not too tight between the floors (usually the thickness of a business card can be stored between the floors). In the Northeast, Northwest and North China, it is generally better to lay the floors tightly.

4. Closing bridge installation.

At the interface connection between the room, hall and hall, the floor must be cut off, and the expansion joints must be left full, and the door and the ground should be connected with a sufficient distance of 3-5mm so that the door can be opened and closed freely.

5. Skirting board installation.

The thickness of the optional baseboard should be greater than 15mm, and the gap between the expansion joints of the floor should be within 5-12mm during installation, and the polystyrene board or elastomer should be filled to prevent the floor from loosening. If the wall or foundation is uneven, the appearance of gaps is expected, you can ask a decorative wall worker to repair the joints.
