What s going on with the bulging floor at the entrance outside the bathroom

The seams bulge.

A. 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;

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

Close to restrooms, kitchens, heating pipes, air conditioning condensate outlets, windows, etc. If the flooding 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;

C. Bulging of short joints of the floor: It is manifested as the bulging of each short joint of the long floor, which is usually caused by the moisture of the ground. The higher the bulge, the greater the moisture on the ground.

Repair program: replacement of the floor.

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

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

B. 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;

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

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

E, the floor under the base arch, such as the original ground before the installation of the floor has a solid wood floor, after the installation of the floor due to the original floor moisture arch, resulting in the floor being arched;

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.
