First, the seam starts to drum
A. Water in the surface of the floor: During the installation process, it is inevitable that the glue does not completely fill the seam. If the mop drip when mopping the floor will cause water on the surface of the floor and enter from the seam with less sizing, the floor substrate will absorb moisture, causing local expansion and blistering. In this case, the surface of the floor surface is partially bulged;
B. Under the floor, the water enters the drum: the surface phenomenon is that the shape of the joint is more uniform, the place near the water source is heavier, and the far place is more and more flat. Somewhere with such problems are: close to the bathroom, kitchen, heating pipes, air conditioning condensate drains, windows, etc. If the water immersion time is long and the surface phenomenon is not obvious, the floor can be opened to check whether there is a watermark to determine the cause;
C. Short seams on the floor: It is expressed as a long floor. Each short side seam is a drum, which is usually caused by too much moisture on the ground. The higher the bulge, the greater the tidal moisture on the ground.
Maintenance plan: Replace the floor.
Second, the floor arch
Surface phenomena are all stepped on and there is a sense of suspension, and some places will be more serious.
A. The expansion joint is not reserved enough to make the floor arch;
B. Room-wide shop: Two or more rooms are not equipped with buckles when installing the floor. When the moisture and moisture are large, the two rooms floor are stretched laterally, causing the door to be involved in each Other to make the floor arch;
C. 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;
D. During the installation process, foreign objects remain under the floor, causing arching;
E. The base layer under the floor is arched. If the original floor has a solid wood floor before the floor is installed, the original floor is damp and arched after the floor is installed, causing the floor to be arched;
Maintenance plan: start the skirting board, reserve the expansion joint again; install the buckle at the connection between the room and the room; re-install the baseboard, clean out the expansion joints such as plaster and putty; open the floor and refill; The floor is dropped, the floor is leveled, and the floor is re-paved after drying.
Third, the floor crack
A. The ground is uneven: the floor is paved under the condition that the ground is uneven, and after a period of use, the glue between the floors is separated to create a gap;
B. Less glue: the floor is in the winter, there is heating and baking, the air is dry, the floor is flat, the joint glue is insufficient, the strength is not enough, and the floor is opened and the seam is cracked;
C. There are heavy objects on the opposite side: the parallel opposite direction of the floor to be repaired is pressed by heavy objects, so that the floor cannot be freely contracted and cracks occur; such a room will be arched in the summer, and cracks will occur in the winter when the heating comes. phenomenon;
Maintenance plan: remove the floor, the floor is leveled, dry and re-paved; according to the size of the crack, decide to add wax, refill; use special tools to fix or reload; remove heavy objects, refill and fix.
Fourth, surface defects
A. Falling angle: The floor bumps during the handling process. The construction personnel do not pay attention to it during the construction process or shovel when cleaning the glue after the construction, so that the corners of the floor have a corner drop phenomenon;
B. Surface peeling: After construction, sharp objects or heavy objects fall off the floor, which affects the appearance of the floor; or the surface layer and the substrate are not glued during the processing of the floor, after a period of use, the surface layer and the substrate are degummed;
C. Scratches: When the customer puts furniture or heavy objects on the floor, the floor and the items are mixed with nails or sand, etc., and the floor wear layer causes the floor wear layer to be damaged or has obvious scratches; maintenance plan: Repair or replace the floor with wax blocks.
