Sticking 1 wall tiles is one of the technical jobs that bricklayers are mainly engaged in in home decoration projects. The pasting procedure of wall tiles is as follows: cleaning the base → painting the primer → selecting bricks → soaking → arranging bricks → springing lines → pasting standard points → pasting tiles → pointing joints → wiping joints → cleaning. Construction must be carried out in strict accordance with standard procedures to ensure quality.
2 wall tile paste construction specification
(1) During base treatment, all kinds of dirt on the wall should be cleaned and watered one day in advance. For example, when the base is a new wall and the cement mortar is 70% dry, it is necessary to arrange bricks, play lines and stick tiles.
(2) Before formal pasting, the standard points must be pasted to control the flatness of the pasting surface. In the process of operation, the smoothness should be checked with a guide rule at any time. If it is uneven or not straight, remove the heavy glue.
(3) Before tiling, it must be soaked in clear water for more than two hours, and then taken out to dry for later use. When pasting, paste from bottom to top. Full mortar is required. When the mortar is insufficient, the heavy glue must be removed. It is not allowed to fill mortar pads from the joints and mouths of bricks.
(4) In case of pipeline, lamp switch, toilet equipment fittings, etc. , must be cut with the whole brick set, it is forbidden to use the whole brick to piece together and paste. The whole or independent part should be pasted at one time. If it can't be done at one time, stubble should be left at the construction joint or internal corner.
(5) The wall brick should be laid from bottom to top, and then the first layer of brick should be pasted. Yin Angle and Yang Can can use Yin and Yang Angle, or the whole brick docking. Yang Angle butt joint brick must be polished along the edge into a 45 angle splicing, bottom-up paste. The side brick of the internal corner should be laid on the same floor as the front brick.
(6) Appropriate amount of 108 glue should be added to the cement slurry to enhance the cohesive force. (30% glue +70% water) Adjust as required (cement mortar ratio 1: 2) and check the tightness with a ruler at any time. Don't stick a wall to the top at once.
(7) When there is an empty drum on the surface of the ceramic tile, the ceramic tile should be removed and pasted again. After pasting for 48 hours, caulking is performed. Add 108 glue or white latex with the same color caulking agent or white plain cement, evenly caulk, and immediately wipe off the surface cement to keep the brick surface clean.
(8) In the renovation of old houses, the original ceramic tiles should be removed first, and then plastered with cement mortar for leveling before paving. When subsidizing the plastered or painted wall with ceramic tiles, the plastered or painted surface must be cleaned to expose the cement wall and cut hair.
(9). Brick walls at the grass-roots level shall be cleaned, and then fine cement mortar mixed with 108 glue shall be brushed.
Acceptance of pasting four wall bricks
The wall tiles must be pasted firmly, and the hollowing rate should be within 3%. There are no defects such as skew, missing edges, falling corners and cracks. The plastering surface of wall brick should be smooth and clean, with coordinated colors and reasonable pattern arrangement, without discoloration, pan-alkali, stains and obvious gloss damage. Brick joints should be filled with dense, straight, uniform width and consistent color, and the lap joint at the corner of Yin and Yang should be in the right direction. Non-whole bricks should be used in proper positions and arranged neatly. The reserved holes are correct in size and neat in edge. Check the flatness with a guide rule, the error is less than 2mm, the vertical error of the facade is less than 2mm, the joint height deviation is less than 0.5mm, and the straightness is less than 2mm.
Upp floor tile technology
1 When laying floor tiles, clean the ground ready for construction, and deal with the damaged ground or loose ground at the same time.
2 Pop-up datum line, standard height and wall horizontal line.
3 Before laying the floor tile, check the color number of the floor tile for quality problems. If quality problems are found in the materials, the relevant person in charge shall be informed in time, and the construction can only be started after the relevant person in charge has properly solved them.
4 The ground base should be rough, clean and wet. If the surface is smooth, it should be pre-cut, and the cement floor should be watered and wet before laying.
5。 Floor tiles are generally laid with 32. 5 Ordinary cement. The proportion of sand is 1: 2.5. During paving, attention should be paid to the consistency of color number and pattern, and there should be no damage.
6. Cement mortar for floor tile must be semi-dry and semi-wet. One hand can't get out of water. In a few days, after the water in the cement mortar evaporates, the mortar under the floor tile will collapse and the brick will be empty.
7 when bricklaying, the brick must be compacted with a rubber hammer, that is, the brick and mortar are firmly combined, and the mortar below the brick can also be closely combined.
8。 After the shop is stuck, the cement mortar shall not be trampled or walked before solidification, and the board surface shall be covered with hard paper or carpet to protect the flatness of the board surface. Use hook agent: hook.
9. There used to be tiles, which need to be resurfaced. You have to shovel off the original tiles, otherwise it will be difficult to stick them together.
10. When laying vitrified brick, pay attention to protection, and don't let dirt seep into the brick surface.
Tiqi tile acceptance
The acceptance method of floor tiles is similar to that of wall tiles. For kitchens and bathrooms with floor drains, see if there is a suitable slope to let water flow to the floor drain without water accumulation. The contact between the tile and the floor drain is smooth.
8. Other issues related to tiling.
(1) The height difference between floor and floor tile is not big, and it can be solved by lintel. The height difference is large, so you can level the floor with cement or solve it with bedding.
(2) How to check and accept the ceramic tiles delivered to the door?
1. Confirm the quantity, and purchase the tiles piece by piece, and round them off.
2. There is the most important point! Check if it is a color number! Forgot to check, posted it will be miserable! Remember the color number or fill the brick!
3. It's best to keep a few tiles of each kind! In case of any damage in the future, it is conducive to backup.
(3) Good cement should be used for tiling, and special attention should be paid to those packages made for the construction team. They are not responsible for maintenance, and often use inferior cement, which can save 5 yuan per bag and earn about 200 yuan more. How to judge the quality of cement can be seen. Cement paper bags are well packed and marked. The signs on the paper bag include: factory name, production license number, cement name, registered trademark, variety (including variety code), label, packaging year, month, day and number. Different colors are used for different types of cement, such as red for portland cement and ordinary portland cement, green for slag cement, and black for pozzolanic cement and fly ash cement. Twist cement powder with your fingers, and it feels a little fine, with sand and powder, indicating that the fineness of cement is normal. The color is dark gray or dark green. 4 will not agglomerate due to moisture. Be sure to see the production date of cement clearly.
Cement also has a production date, and the performance of cement beyond 30 days is degraded. The strength of cement decreases 10%-20% after three months, 15%-30% after six months and 25%-40% after one year. High-quality cement, which can set in more than 6 hours. /kloc-cement that cannot be solidified after 0/2 hours is of poor quality. If the workers told you a day ago that the tiles could be removed and replaced, the quality of the cement must be very poor. Then after 2-3 months, some tiles may bulge and fall off!
If you are not sure, you can also do a curing experiment. Add appropriate water to the cement and stir to solidify it. After 6 to 12 hours, see if it is caked. If the powder is inferior cement, it means it has deteriorated or expired. If the brick you put on it is easy to fall off after a day or two, it means that you are using inferior cement. Good cement does not need glue, and poor cement does not need glue. Sticking wall tiles and adding 108 glue can strengthen the adhesion between cement and wall.
(4) On the smooth cement wall, the ground is calendered. Before laying bricks, the walls and floors should be brushed. You can't stick bricks directly on the wall paint. To nap is to roughen the surface.
(5) Dry paving is often used for floor tiles and wet paving for wall tiles.
(6) Wrap the riser with light steel keel and cement board, and the cement board will be pasted with ceramic tiles and hung with barbed wire. Otherwise, it will fall easily.
(7) The special tools of 1 are needed for punching ceramic tiles. First of all, use a hollow tubular diamond drill to punch holes in the tiles, remember; The hole must be larger than the actual hole 1.5-2mm. This kind of hollow tubular diamond drill has various specifications in the building materials market, and the price is about one fifth. After the ceramic tile is drilled through with a hollow tubular diamond drill, it is punched with an electric hammer according to the required hole size.
For example, the required holes should be
