Floor tile installation steps and precautions

1. The standard procedure for floor tile paving is: cleaning and finishing the ground floor → cement mortar leveling → calibration height, elastic line → installation standard block → material selection → infiltration → paving → irrigation → cleaning → maintenance work.

2, the ground of the old house must be fully roughened, the concave depth is not less than 0.5mm, the spacing is 5cm, and then the net cement slurry is brushed again. Be careful not to collect water and prevent it from seeping through the seams downstairs.

3. For the requirements of drainage slope, such as the bathroom, bath room, etc., the slab slope should be controlled according to the corresponding slope.

4, substrate acceptance: surface leveling with 2m ruler inspection, the deviation should not be greater than 5mm, the elevation deviation should not be greater than ± 8mm.

5, stone, floor tiles varieties, specifications, colors and patterns should meet the requirements of the design, the residents, the surface of the veneer must not have scratches, lack of edge and other quality defects. Expired and agglomerated cement should not be used as a binder. The floor tiles must be unpacked before they are laid.

6. Before the floor tiles are laid, carefully measure them with computer as much as possible, and select a reasonable plan to count the specific number of bricks, aiming at arranging the appearance and reducing the loss, and focus on checking whether the geometrical dimensions of the room are neat.

7. The mortar uses 1:2.5 cement mortar volume ratio (the specific grip is: hand clumping, landing flowering), the bonding layer should not be less than 12mm thick, the mortar is full, and the cement uses the Dachang cement. 800×800 polished brick or granite with a volume ratio of 1:4～1:6 cement mortar. 600×600 (including 600×600) and 500×500 or more floor tiles should be dry-laid. Light-colored granite and marble are coated with white cement to prevent flooding.

8. Before the floor tiles are laid, they should be immersed in water to dry and then wet in the outer dry. The surface is free of water and used for color selection.

9. Before the paving, the crosshairs should be pulled in the horizontal and vertical directions. When paving, the horizontal and vertical lines must be ensured to pass through, and the seams must not be staggered.

10. When the floor tiles are laid, keep them clean and clean with the shop. (Use cotton yarn or sawdust to clean), and clean the cement mortar in the brick joint, and then finish the joint and finish the joint.

11. The joint is carried out before completion. Firstly, the joint is cleaned, and the white cement and talcum powder are used to adjust the putty. The joint putty is 1mm lower than the brick surface.

12. When the floor tiles are laid, other types of work shall not be polluted, and no artificial trampling shall be carried out. After the completion of the floor tiles, the seams shall be cleared within 24 hours, and they shall be cleaned up and maintained. It is forbidden to be employed within two days. In order not to affect the construction of other projects, solid wood panels can be laid on the ground for people to walk.

13. After the floor tile is laid, after checking the unevenness error, empty drum, chromatic aberration, etc., all the cardboard is covered and protected. The nails on the cardboard must be removed. The cardboard and cardboard must be tightly sealed with sealing glue to prevent it. The debris enters.

14. It is strictly forbidden to use water when there is no drainage or no water storage equipment, especially to prevent the board used for soaking the floor tiles to prevent indirect pollution of the floor tiles.

15. The foundation filling such as flower pool and toilet is filled with wetting concrete and carbon residue, so that the filling is compact, firm and reliable, and light in weight, and there is no safety hazard in weight bearing.

16, stone or tile baseboard according to customer requirements can be flush with the wall facade, so that the construction is not dusty, easy to clean, good furniture.

Common quality problems and treatment methods for floor and floor tiles

The common quality defects of floor and floor tile paving are the large deviation of the flat and flatness.

1. Empty drum: The main reason is that the cement layer is thin, the cement slurry is dry when the paving is applied, the pollutants on the back of the board are not removed, and the maintenance period is too late for people to walk or heavy pressure. During the construction, the bonding layer mortar should be dry, which is subject to the grounding. The water-cement ratio of cement slurry is 1:2 (volume ratio) when paving, and it is strictly forbidden to use cement flour. During the curing period, the board should be erected and it is forbidden to walk on the surface. If there is an empty drum, it should be reworked. The method is to take out the empty floor tiles, suck them with suction cups, hang them straight, and then lay them out according to the specifications.

2, the flatness deviation is large: in addition to the improper construction operation, the board surface is not flat, the main reason is the sheet warping. In the construction, the material should be strictly selected, and the unqualified products with serious warpage should be removed. If the thickness is uneven, the mortar can be leveled in the back of the board. For local deviation, the marble machine can be used for flattening and polishing. If there is no flat plate, it should be removed and reassembled.

Acceptance Criteria:

1, the surface is clean, the lines are consistent, no scratches, no color difference, no cracks, no pollution, lack of edges and other phenomena.

2. The gap between the edge of the brick and the wall is suitable. The skirting board can completely cover the gap, the width is consistent, and the upper mouth is straight.

3. The flatness of the floor tiles shall be inspected with a 2M level. The error shall not exceed 2 mm, and the height difference between adjacent bricks shall not exceed 1 mm.

4. When the floor tiles are pasted, they must be firm. The empty drums should be controlled at 5% of the total, and the single-piece empty drum area should not exceed 10% (the main passages must not have empty drums).

5, the width of the floor tile is 1mm, no more than 2mm, the joint is even and straight.

6, the horizontal error does not exceed 3mm.

7. The floor of the kitchen and toilet should not be higher than the indoor walkway or hall floor; it is better to be 10-20mm lower than the indoor floor.

8. The slope of the floor covering with drainage requirements should meet the drainage requirements. Floor drains with floor drains should be flooded with water (a very small slope) pointing to the floor drain, and the joint with the floor drain should be tight and firm.
