Will freezing tiles affect the quality in winter?

It is not suitable for tiling in winter, because in the case of extremely low temperature, the requirements for tiles are higher, and it is not suitable for tiling when the indoor temperature is -7℃ or -8℃, otherwise the cement mortar will be mixed unevenly, or some silt will contain ice cubes.

1, tiles must be soaked in clear water for more than 2 hours before pasting in winter, so that the water is saturated. Take out the tiles to dry for standby, subject to no bubbling, because the temperature difference between indoor and outdoor is large in winter, whether it is wall tiles or floor tiles, you must wait to adapt to the indoor temperature before using them.

2. Wall tiles and floor tiles need to be moved from outdoor to indoor for 24 hours, and can only be laid after the material temperature rises to adapt to the indoor temperature, so as to avoid hollowing and falling off after construction. After the bricks are built, tick off the joints in time.

In winter, there is a great temperature difference between morning and evening. In order to prevent cracks from physical reaction of floor tiles, joints should be laid. The gap between the floor tiles should not be too big, and it can generally be adjusted between 2-3 mm.

4. After the floor tiles are laid, it is best to open the windows at home to keep the room well ventilated and let the harmful substances disperse in time. On days when it is not suitable to open windows, you can put a pot of baking soda water or green plants in the room to absorb toxic gases.

5, kitchen, bathroom should have a slope of running water, no water, water does not flow back. If the original waterproof layer is damaged during construction, waterproof treatment should be done, and the water accumulation test 12 hours has no leakage.

6. After the floor tiles are pasted, after 1 hour of paving, the cement, caulking agent or other sticky objects remaining on the surface of the tiles should be wiped clean in time, because it is difficult to clean the caulking agent after four hours of pasting.

Key points of construction

1, the operator must have more than two years' practical experience in this project, and obtain the post certificate after training and examination; The professional supervisor shall make professional technical disclosure to the operators according to the design requirements and acceptance specifications, and make sample rooms when necessary.

2. Before construction, check whether the completion of the grass-roots level meets the design and specification requirements and whether the grass-roots level is flat. If it is uneven, it should be repaired one day in advance, and the handover inspection procedures should be completed with the previous process; Check whether the specifications and dimensions of the floor tiles conform to the modular relationship between the design and the actual dimensions on site; Check whether the temperature of the construction surface is conducive to the construction (the construction should be stopped when the temperature is lower than 0℃ in winter); Familiar with drawings and site conditions.

3. Bricks should be selected according to the material acceptance criteria. Generally, 3 ~ 4 specifications are selected according to the grade difference of1mm. All specifications require that the square is straight, the edges and corners are intact, the design and color are consistent, there is no crack, and the surface is smooth without convex and concave and warping. (Whether the floor tiles are soaked before construction shall be subject to the manufacturer's factory instructions)

4, check whether the grassroots level off, whether there are holes in the wall, column and pipeline and ground handover, whether the special parts (stairs, elevator wellhead, escalators, expansion joints, contraction joints, etc.). ) whether the construction is carried out according to the drawings and whether it meets the construction requirements. If it does not meet the above requirements, it should be chiseled or repaired to meet the construction requirements.

5. Clean the pedestal, pay special attention to the cleaning time of special parts in "Point 5-3", and spray water on the pedestal for 24 hours after cleaning.

6, according to the drawings and prepared a variety of baseline (to check in advance) put the construction control line, in the main parts (special parts and different colors, materials, materials junction) pop-up cross control line perpendicular to each other, to control and check the position and construction quality. All kinds of control lines should be inspected and recorded, and the inspected control lines should be protected for effective use.

7. According to the elevation screed required by the drawings, the spacing shall not be greater than 1.5M, and the screed at different elevations shall be subject to the control line. Use 1:2 or 1:2.5 cement mortar for screed, and stay to check whether the height meets the requirements.

8. Sweep the cement slurry (plain cement slurry with water cement ratio of 0.5) evenly on the cleaned base.

9. After slurry sweeping, use 1:2 or 1:2.5 hard cement mortar as the bonding layer on the base. It is required to scrape with a stick and pat with an iron trowel to make the mortar firmly bonded with the base.

10. Before paving, try to pave the floor tile, directly pave the floor tile on the adhesive layer according to the requirements of paving, and vibrate it with a rubber hammer. On the one hand, ensure that the floor tiles are flat and the gaps are straight; On the other hand, if there is no need to fill the mortar, shovel off the excess mortar.
