The perfection of floor tiles often depends on many factors. At the same time, this also tests the skills of the decorator. So, when you buy a new house and decorate it, hire a decorator. When decorating a house, in addition to daily supervision, you must also know some acceptance standards so that you will not be cheated. What are the construction techniques and acceptance criteria for floor tile paving? Let’s find out together!
1. What are the preparations for laying floor tiles?
1. Floor cleaning
Before laying floor tiles, the floor should be cleaned, especially the concrete and construction debris after condensation. If not cleaned, the floor tiles will warp, hollow, etc. after they are laid.
2. Place horizontal lines and divide into blocks
Before paving, the floor tiles must be pre-arranged according to the size of the ground and the size of the floor tiles. The principle of pre-arrangement is: in the same room, the horizontal and vertical half bricks cannot exceed one row, and the half bricks should be kept in the future. On one side of the furniture or in an inconspicuous place, horizontal lines should be set according to the layout plan and divided into blocks.
3. Sprinkle water on the ground
It should be fully moistened to prevent hollowing.
4. Mortar mixing
Two types of mortar are used, one is a 1:4 semi-dry mortar, used as a cushion, and the other is a 1:3 mortar, used for bonding. The sand is washed with medium sand and fine sand. Sand is mainly used for wall plastering, and medium sand is mainly used for ground leveling.
5. The ground should be leveled
Some civil construction floors are uneven. In this case, you should pave the uneven areas with cement mortar. When laying, you can use tiles of different colors (darker) to frame the surroundings, and use lighter colors for the tiles inside the frame. Of course, the floors of the kitchen and toilet must be sloped to facilitate drainage.
6. Sizing the brick base
A layer of 1:3 mortar should be applied to the back of the floor tiles as an adhesive layer. The thickness should not be less than 1CM. The application must be even.
7. The brick surface should be laid flat
The angle must be accurate and the interface must be aligned; the tiles must be soaked in water for half a day before use; the toilet floor must have an appropriate slope and no water can accumulate on the tile interface. Cement stains remain; after the floor tiles are laid, cover the tile surface with cardboard, etc., and wait at least 24 hours before walking on the tile surface.
2. Floor tile construction process
1. Cleanup
Before laying floor tiles, the floor must be cleaned first. If not cleaned, the floor tiles will have warping, hollowing, etc. after they are laid. In particular, there must be no condensed concrete and construction residue.
2. Pick bricks
Select tiles out of the box, and it is not allowed to use damaged or hidden tiles for construction.
3. Bubble bricks
Clean the facing bricks and soak them in water for no less than 2 hours until they stop bubbling. Dry them in the shade until they are ready for use. The degree of drying in the shade is that the surface of the bricks is wet but without water.
4. Pre-arrangement
Set horizontal lines (with tools) according to the design arrangement and divide them into blocks. The arrangement of floor tiles is for overall aesthetics. In a room, there should be no more than one row of horizontal and vertical half tiles, and no half tiles should appear in obvious places. Generally, half a brick is laid on the side where furniture is not to be placed or where it is not obvious.
5. The base layer is moist
Sprinkle water on the ground before laying floor tiles to make the ground fully moist, which can prevent hollowing.
6. Paving dry mixed mortar
Trial paving first will help the base layer to be leveled and compacted. It must be compacted so that there will be no hollowing after the floor tiles are laid. When trial paving each tile, check whether the floor tile is level with the adjacent floor tiles, and the corners cannot be There is a gap.
7. Pre-paving bricks, and leveling the base with dry and wet mortar
8. Floor tiles covered with plain mortar
Take off the trial floor tiles and slurry the bottom of the tiles. on the back of floor tilesApply a layer of 1:3 mortar on the surface as an adhesive layer. The thickness should not be less than 1CM. The back of the floor tiles should be evenly applied.
9. Tamp with a leather hammer, adjust the paving, and adjust the cross brick card
Use a rubber hammer to tap evenly, paying attention to adjusting the level with the horizontal line and other floor tiles and the size of the gaps between the floor tiles. It is best to use a spirit level to check whether the tiles are level, and use a rubber mallet to tap until they are completely level.
10. Worker self-inspection of third-level inspection
11. Inspection and floor tile protection
24 hours after the floor tiles are laid, they should be sprinkled with water 1-2 times a day for maintenance. No one is allowed to step on them within 2 days. After 2 days, clean the surface dust, gravel, etc., and the company's professional engineering housekeeper will inspect and accept it. After passing the inspection, the cleaning is completed. Then use Meichao special protective film to protect the ground.
3. What are the acceptance criteria for floor tile paving construction?
1. Pay attention to whether the floor tiles need to be parquet or laid in the same direction.
2. Use a 2-meter level to check the flatness of the floor tiles. The error shall not exceed 0.5 mm. The height difference between adjacent tiles shall not exceed 0.5 mm. The flatness of the gaps shall be 3 mm. When laying the floor tiles, other types of work shall not contaminate the floor tiles. Human trampling. After the floor tiles are completed, the joints will be cleared 24 hours a day, and they will be cleaned and maintained as needed.
3. The hollowing phenomenon of floor tiles should be controlled within 3%. The hollowing on the main channel must be reworked. 3% only refers to the hollowing of the corners of a single block, and the whole block must not be hollowed.
4. After laying the floor tiles, check the flatness for errors, hollows, color differences, etc., then cover them all with thick cardboard or plywood, old carpets, etc. The seams between the tiles must be tightly pasted with wide paper tape to prevent clutter. things enter.
5. Under normal circumstances, the level of the floor tiles is allowed to have an error of 2 mm. The gaps between the floor tiles must be consistent. The diagonals between the bricks should be flat (an error of 0.3 mm is allowed). The kitchen and bathroom wall tiles must be flat. In addition to the fact that the diagonals between bricks should be flat, the horizontality (1 mm error allowed) and verticality (2 mm error allowed) must be achieved. Floor tiles in bathrooms and balconies need to be considered for floor drains, and the slope must be placed first.If there is no special reason, there should be no accumulation of water.
Wow, Mr. Zhongtao couldn't help but sigh after reading this. There is too much content, but it is all practical information. You should read it carefully, or read it a few times so that you will remember it. , OK, the above content is what Zhongtaojun shared with you about the construction technology and inspection standards of floor brick paving. How much have you remembered? So, you see, Floor tile laying is a delicate job! , is not an easy thing to come by. Well, today’s content is shared here. I hope it can be helpful to you!
