The surface of the wooden floor has vertical protrusions, which are very thin, and they seem to be c

It should be a quality problem, but this is not easy to solve, it can only be said that you are not good at selecting materials. The floor requires that the material is not easy to deform, and if the deformation is too strong, there is no way to maintain it. For your current situation, it is recommended to add a little humidity at home, if the crack is large, buy a bottle of 502 with a thin tube to point at the crack, and immediately wipe it with a waste cloth back and forth in a straight line.

Talk to the manufacturer about what (benefit) you will get. It's already like this, there is no way to get it right, only to improve. Because your current quantity is small, it is better not to repair it on a large scale, and you can't use scotch tape (you will regret it).

Waxing (liquid) 1 to 2 times a month.

This situation is relatively common in solid wood flooring, but don't worry, basically the problem will not be very big, the defect rate is within the normal range, and it is not a serious quality problem. In particular, if the three pieces are not in the place where they often walk, they will generally not be expanded, because their shrinkage and expansion have been saturated, just pay more attention to whether there will be such a problem in other places in a large area, if there are too many floors, the manufacturer will be required to compensate, which is a serious quality problem.

This is a quality problem, which is the cracking of the paint film caused by the substandard moisture content of the blank during floor processing, which can be repaired. If the quantity is small, do not replace it.

Yes, it will bulge up because of the moisture absorption, and the water will suddenly dry and crack even more, affecting the wooden floor next to it.

What is wooden. Are wooden conduits thick?

Caused by drying and shrinking of wood.

The temperature and humidity change too much compared to the time when the shop is spreading.

1. According to the relevant national regulations, under the current construction technical conditions, a certain degree of cracks is inevitable, but the shape, number and width of cracks should be controlled within a certain range. If it is a penetrating and structural crack that may endanger the safety of the house structure, such as foundation settlement cracks, the wall cracks should be reinforced accordingly immediately. After the crack is discovered, it should first be re-verified by the designer, construction party and other responsible entities entrusted by a third-party engineering quality inspection agency.

After determining the nature of the crack, the responsible party should communicate with the occupant and issue a specific repair and solution to the crack.

If the quality inspection of the foundation of the commercial housing is carried out by a professional testing agency and it is confirmed that the quality of the housing has been seriously affected, the owner can request to terminate the contract and choose to move out; However, if there is a subsidence of the foundation, but after the quality inspection of the commercial housing by the testing agency, it is believed that the reinforcement and repair can ensure the safe living and use, there is no need to terminate the contract.

2. According to China's construction laws and regulations, housing quality problems mainly include the following categories:

1) The quality problems of the foundation engineering and the main structure engineering of the house, including the cracking of the wall, the subsidence of the foundation, the inclination of the house, etc.

2) The quality problems of the waterproofing project of the house, including water seepage on the exterior wall, water leakage on the roof, etc.

3) The quality of other civil works is the same. Including loose doors and windows, peeling paint, sand on the indoor floor, etc.

4) The quality problems of the installation engineering of electrical pipelines and water supply pipelines mainly refer to the installation of electrical circuits, switches, and drainage pipes.

5) Heating and cooling system engineering quality problems, which refers to the quality problems of heating equipment, air conditioning equipment and other installation projects.

3. It is not the above quality problems of commercial housing, buyers can ask to check out, and only when the quality problems are serious and affect the normal residential use of commercial housing, buyers can ask to check out. According to paragraph 1 of Article 13 of the Interpretation of Several Issues Concerning the Application of Law in the Trial of Cases Involving Disputes over Contracts for the Sale and Purchase of Commercial Housing, "if the buyer's request to terminate the contract and compensate for losses is seriously affected by the quality of the house, it shall be supported."

It is clearly stipulated that only when the quality problem reaches a certain level and seriously affects the normal residential use, the buyer can request to terminate the contract, check out to the real estate development enterprise, and at the same time require the real estate development enterprise to compensate for losses.

Fourth, it is generally believed that serious impact on normal residential use refers to the serious quality problems of the commercial housing purchased by the buyer, the quality problem cannot be repaired to make the commercial housing meet the normal standard, the normal residential use of the buyer cannot be guaranteed through repair, and the personal and property safety of the housing user cannot be guaranteed through repair. For example, if the load-bearing structure of the house is deformed, seriously threatening the personal safety of the house users, and it is impossible to ensure normal use and restoration, it shall be found to seriously affect the normal residential use.

5. In practice, the engineering quality inspection agency shall conduct quality inspection on the commercial housing, and determine whether it seriously affects the normal residential use according to the conclusion of the quality inspection.

According to your description, it may be: the floor concrete demoulding is too early or the over-rib is damaged, so that the developer's engineering department can issue a written thing to admit the existence of this fact, and if the crack continues to grow and expand, it is required to change the house, and you can complain to the local quality supervision station

It is best to find a quality inspection department to make a quality appraisal, there is really a quality and safety problem, and then take the appraisal to find the developer to file a lawsuit and make a claim, change the house or something.

Do you use laminate or solid wood? Every manufacturer's flooring will be defective. If the after-sales attitude is not good, you can remember its number, and it is not negotiable to directly submit.

Brand goods are mainly advertised, and the cost is added to the floor, so it is so expensive In fact, the quality is almost the same as the ordinary one, and the floor is divided into grades, and the A board is the same.

If there are no cracks in the wall, the problem is not too big, and the wall is most afraid of diagonal through cracks from the upper corners of doors and windows to the upper corners, which is a manifestation of foundation sinking.

The cracks in the ground on the first floor may be caused by insufficient backfilling and tamping of the soil in the center of the house, and if you hit it with a wooden hammer, there will be a hollow sound, you can give it a try.

If it's like this, you can ask for the floor to be rebuilt, and you can be justified.

Such a ground will collapse sooner or later, although there is no obstacle to safety, but the paving floor tiles will not break and break.

It is recommended to ask a professional to check on the spot, and if necessary, professional testing is required.

If the city is designed and constructed according to the specifications and delivered to the house or the village has been used for many years, after determining that there is no foundation change (such as landslide, subsidence, ** and other reasons), it can be preliminarily judged to be a crack, damage and other causes, and the cause can be found and dealt with according to the attached table.

According to the phenomenon described in lz, it is basically determined that the surface plastering crack is caused by a large change in temperature, but it is also necessary to pay close attention to the change of the river bank that may cause structural damage to the house. In addition, it is normal for the car to be vibrated and there is no need to worry.

Ground leveling is best done on the ground with calendering, so the surface should be smooth and flat. After the ground is leveled, cracks and hollows appear on the ground, and the solution of this problem should be treated differently according to the specific situation, and the suggestions are as follows:

1. If there are only cracks and there is no hollow delamination, the cement mortar can be used to grouting the cracks.

2. If there is a crack and there is a hollow drum delamination at the same time, it is necessary to smash the cracked hollow drum area and re-use cement mortar leveling.

3. If there is an area of hollow drums on the ground that is less than 400c (20 cm square) and the number is less than 3 places, basically it can not be treated.

Smooth is good, the professional term is calendering, in fact, calendering or not calendering is the key to whether the flatness of the ground is good, otherwise it is empty talk. It doesn't matter if the cracks are cracked, the hollow drum should be removed and reprocessed.

Shovel and redo it, sprinkle water on the ground, clean it up, and the cement mark should not be very small.

Floor damage can be repaired in a few small ways. If the lacquer is dull, there are two ways to restore the luster of the wood floor

First, use a glass of water and a quarter cup of vinegar and wipe it with a soft cloth; The second is to wipe with a soft cloth soaked in alcohol or toilet water or tea, and then wipe the floor wax again. If a small piece of paint peels off on the surface, it can be patched with advertising pigment of the same color, and then applied to the surface with varnish to make it intact. There are two ways to repair cracks and holes on the board surface

The first is to cut old books and newspapers into crumbs, add an appropriate amount of alum, boil them with water into a paste, embed them in the seams, and dry them very firmly.

Second, mix sawdust with white glue to adjust evenly, embed cracks, and polish with sandpaper after a day and night, which is simple and economical.

The phenomenon of wet expansion and dry contraction of the wooden floor, it is difficult to avoid the room where floor heating is installed, but the size of the seam is a problem, generally speaking, the seam should not be filled with hard filler; In this case, as shown in the picture, it can only be solved with a pressing strip, and if a hard filler is used, once the floor is mopped, there may be a problem of protrusion.

Your home is a parquet floor, this floor is not very swollen, the installation may be a large seam at the foot line, winter floor heating due to dryness and shrinkage, different hot days.

The installation was not done properly, resulting in a gap in the space.

What is the reason for the dangerous crack? Is it a quality problem or construction damage? If it is a quality problem, it will definitely affect the future use, if the construction is accidentally damaged, it is a small crack or will not affect the overall performance. 、

It depends on where your crack is, if it's in the corner, it doesn't matter, if it's in the middle, it's recommended to have surgery.
