What are the taboos of laying hardwood floors?

1.Uneven ground: Uneven ground will cause part of the floor and keel to hang in the air, making a noise when stepping on it.

2.The keel is not moisture-proof: the moisture content of the undried wooden keel is usually about 25%, and the moisture content of the qualified wooden floor is generally 12%, and the humidity difference is too large to make the wooden floor absorb moisture quickly, resulting in the arching of the floor and the bursting of the paint surface.

3.Too loose or too tight: As the ambient temperature and humidity change, the wood floor will expand or contract.

Therefore, when laying the floor, the assembly tightness of the wooden floor should be reasonably arranged according to the ambient temperature and humidity of the place where it is used. If it is too loose, the floor will shrink and there will be large gaps, and if it is too tight, the floor will arch when it expands. Fastened with iron nails:

In the construction, the fixing method of beating the wooden wedge and adding the iron nail will cause the nail holding force to be insufficient because the contact surface between the wooden wedge and the iron nail is too small, and it is easy to cause the wooden keel to loosen, and there will be a sound when stepping on the floor.

4.There is a crossover in the project: the floor is laid first, and then other construction is carried out on the floor, which is the usual practice of the renovation team at present.

However, after the floor is laid, it often takes a month or more to polish and paint. During this period, the floor is not isolated from the surrounding environment by moisture and chemicals, which is likely to cause the wooden floor to deform and crack due to the rapid change in moisture content.
