My floor has not been leveled, and the floor is now empty due to the weather, is there any way to re

How to solve the floor drumming?

1. Remove the arching wood block and the surrounding floor to ventilate it, which can alleviate the arching problem; Pry up the floor at the arch in a large area, wait for the ground and keel to dry, and then lay the floor back; Pay attention to maintaining the normal contact between the floor and the outside world to balance it with the atmospheric humidity; If the arch is severe, it can be replaced.

In order to prevent the floor from arching, experienced laying masters will leave a certain small gap in advance when paving the floor, leaving room for "thermal expansion and cold contraction" for the floor.

2. If the expansion joint is blocked, get the things in the expansion joint out.

3. Replace the new floor, when repairing, remove the deformed floor plate, pave the ground with cement, and replace it with a new floor, so that the floor will be as smooth as ever.

4. The main reason for the uneven surface is the uneven base or the deformation and bulging of the floor strip. During construction, the level should be applied to level the surface of the keel, and if it is uneven, the skids should be adjusted. A small ventilation groove should be made on the keel. The edge of the board should be 10 mm away from the wall for ventilation.

The insulation and soundproofing material must be dry to prevent the board from bulging after being wet. The flatness error of the surface of the wooden floor should be within 1 mm.

5. The reason for the sound of hollow drums is that the fixation is not real, mainly because the number of nails on the wool board and keel, wool board and floor is small or not firmly nailed, and sometimes it is caused by shrinkage or unqualified glue caused by the change of moisture content of the board.

Therefore, it is particularly important to strictly inspect the quality of the board moisture content and adhesive. It can only be used after passing the inspection, and the nails should not be too few when installing.

6. In addition to the non-standard installation during construction, the width and size error of the plate and the poor processing quality are also important reasons.

7. In addition to the deformation of the board due to moisture, the main reason for the local warping is that the joints of the wool board are too small or seamless, and the water pipes and other leakage blisters are caused by the wet board. After the floor is paved, the paint film should be intact when the floor paint is painted, and the water on the surface layer should be cleaned up in time to prevent water from flowing into the lower part of the floor in daily use.

There is no remedy for this situation, the general practice is to knock the hollow floor open, and then re-pavement, but it is best to see if there are such problems in other places after a while, and then repair them together, the root cause of such problems is that the construction materials such as cement are not qualified, or the previous floor is not dry before the construction. Next time, it is recommended to find an experienced construction team to carry out the construction.

If the crack is small, the problem is not big, it is also normal, if the crack is too large and there is a hollowing phenomenon, it is abnormal. The reason for the problem may be that the thickness of the screed is too thin, and the ground is not brushed or glued before leveling.

Ask the mason master to deal with it in Laibang, it is not a big problem, but it will affect the flatness of the wooden floor.

Laminate flooring due to the use of suspended pavement, allow the ground to have a certain height difference, but not too much, 2 mm per square is OK, cracks and hollow drums on the ground are absolutely not allowed, which will cause problems such as sound on the floor in the future! If it is a solid wood floor, because it needs to be installed with a keel, this situation on the ground is even more allowed! If you paste tiles, you can shovel off this layer of cement, and directly paste the tiles, because if you paste tiles, you need to do cement slurry under the tiles, and the thickness should be more than 2 cm, but you should also pay attention to the fact that the cement can not appear bubbles or hollow drums, I suggest that you still find workers to redo the ground, and then lay laminate flooring!

What you say is called the "hollow" phenomenon, and the hollowing phenomenon of the cement mortar screed layer is because there are dirty things on the ground before construction that have not been cleaned. If there are only a few hollow drums (each area is less than 10cm2, and the number of blocks is not much), don't care about it, if it has been leveled for many days, it is still this phenomenon, and the other non-empty drums will not be hollow anymore. If there are many hollow drums, it is necessary to rework, that is, after smashing the large area of the hollow drums, remove all the debris on the ground, fully rinse with clean water, and then lay mortar and flatten when there is no stagnant water.

In order to ensure the quality, after the screed layer is white, it is often sprinkled with water for maintenance, at least five or six times a day, and generally three to four days of maintenance is enough.

Wooden flooring can only be constructed after the screed has dried.

Small cracks have no effect on the floor, if it is more long, it will have an impact, because the screed layer has a large hollow area, and it will fall down after a long time, and the wooden floor will also be propped off.

Small cracks have no effect, do not need special treatment, if not assured, can be grouted, the ground before the installation of composite wood flooring to see whether the flatness of the ground meets the requirements of paving, generally do not need to level, unless the height of the ground is very different. If there is a keel, it can be considered leveled.

If the flatness of the ground is okay, you only need to use a special moisture-proof mat for the floor, which has a certain thickness and can be leveled with a moisture-proof mat.

There are generally two kinds of leveling, one is leveling between different use areas, and the other is local cloth leveling. If you need to use cement mortar, the cement must be paved to an absolute level, then 2-3 cm of cement must be laid; It is recommended to be flat, that is, to use cement or putty for the wall to batch a thin layer, not required on the absolute horizontal plane, is to ensure that there is no uneven place, may be oblique horizontal, so that the floor will not have a sound, the horizontal plane is inclined with the naked eye is generally difficult to see. It also does not affect the laying of laminate flooring.

This is caused by the phenomenon of thermal expansion and contraction of cement, which is normal, you can install the floor on it, right.

Screed? Isn't there a surface layer on top? It's okay to have a little crack in the leveling layer.
