Tile on the wall, small things, big craftsmanship. Today, the editor will introduce the causes and prevention measures of the problems encountered during the process of tiling on the wall.
What are the reasons and prevention measures for uneven rack like adhesive layer?
1. The grassroots is uneven.
2. The thickness of the scraped tile adhesive is insufficient, and the tile adhesive is not fully scraped.
3. The trowel teeth have dried ceramic tile adhesive, and the trowel should be cleaned.
4. The scraping speed is too fast, the scraping speed should be slowed down.
5. The ceramic tile adhesive is not evenly mixed and contains powder particles. It should be thoroughly mixed and cured before use.
When there is a large deviation in the flatness of the grassroots, how to use the thin pasting method to tile?
Firstly, the base layer needs to be leveled to meet the requirement of flatness ≤ 4mm/2m, and then the thin pasting method is used for tile pasting construction.
What should be paid attention to when pasting ceramic tiles on ventilation pipes?
Before pasting, check whether the internal and external corners of the ventilation pipe are 90 ° right angles, and ensure that the error between the angle and the pipe endpoint is ≤ 4mm. The gap left for cutting tiles with a 45 ° external angle should be uniform and not tightly pasted, otherwise it will affect the bonding strength of the tiles (wet and hot expansion can cause the edges of the tiles to explode and be damaged); Reserve a spare maintenance port (to avoid damage and disassembly during pipeline cleaning and dredging, which may affect the appearance).
4. Installation method for floor tiles with floor drain?
When laying floor tiles, it is necessary to find a good slope to ensure that water from all positions can flow into the floor drain, with a slope of 1% -2%. If two floor drains are configured in the same interval, the center point between the two floor drains should be the highest point and laid on both sides; If it is a matching wall or floor tile, the floor tiles should be laid in parallel with the wall tiles.
5. What should be noted when using fast drying ceramic tile adhesive outdoors?
The overall storage time and drying time of fast drying ceramic tile adhesive are shorter than ordinary ceramic tile adhesive, so the mixing amount should not be too much at once, and the scraping area should not be too large. Construction should be strictly completed within the product's usable time according to requirements. It is strictly prohibited to use ceramic tile adhesive that has lost its workability and is close to setting after mixing with water again, otherwise it will greatly affect the bonding strength in the early and later stages, and may cause serious whitening. It should be mixed and used as needed. If it dries too quickly, the mixing amount can be reduced, the mixing water temperature can be appropriately lowered, and the mixing rate can be appropriately reduced.
6. What are the reasons and prevention measures for the phenomenon of hollowing or decreased bonding strength of ceramic tiles after bonding?
Firstly, it is necessary to check factors such as grassroots quality, product quality validity period, and water distribution ratio.
Then, in response to the phenomenon of hollowing or decreased adhesion caused by the tile adhesive being left to air for too long during pasting, it is important to note that the pasting should be carried out within the air drying time, and slight rubbing and pressing should be applied to make the tile adhesive dense.
In response to the phenomenon of hollowing or decreased adhesion caused by adjusting again after the adjustment time, it should be noted that in this case, if re adjustment is needed, the tile adhesive should be removed first, and then re grouted for pasting.
In view of the phenomenon that the insufficient amount of tile glue leads to excessive pulling out during the front and back adjustment when pasting large facing tiles, which causes the glue to delaminate, cause hollowing or reduce the cohesive force, it should be noted that during the pre paving, the amount of glue should be as accurate as possible, and the front and back distances should be adjusted by hammering. The thickness of tile glue should not be less than 3mm, and the pulling out adjustment distance should be about 25% of the glue thickness.
In response to the hot and dry weather and the large area of each batch scraping, which causes some of the adhesive surface to lose water, the area of each batch scraping should be reduced; When the tile adhesive has lost its viscosity when lightly touched by hand, it should be scraped off and reapplied. If the adjustment has exceeded the adjustment time and is forcibly adjusted, the slurry should be removed and replaced. The thickness of the tile adhesive is insufficient and needs to be supplemented with grout.
Attention: Adhesives that have solidified and hardened beyond the operable time should not be mixed with water or other substances before use.
7. When cleaning the paper on the surface of ceramic tiles, what are the reasons and prevention measures for tile detachment?
For those caused by premature cleaning, cleaning should be postponed, and the tile adhesive must reach a certain strength before cleaning. If there is an urgent need to meet the construction deadline, it is recommended to use fast drying ceramic tile adhesive. Cleaning can only be carried out at least 2 hours after the tiling is completed.
What should be paid attention to when pasting large areas of ceramic tiles?
When pasting large areas of ceramic tiles, attention should be paid to:
1) Paste the tile adhesive during the drying time.
2) Use enough adhesive at once to prevent insufficient amount of adhesive from requiring replenishment.
9. How to ensure the quality of soft ceramic tiles as a new decorative paving material?
The selected adhesive needs to be tested in conjunction with soft ceramic tiles, and a strong adhesive tile adhesive should be used for bonding.
10. Do tiles need to be soaked in water before pasting?
When using qualified tile adhesive for pasting, tiles do not need to be soaked in water, and the tile adhesive itself has good water retention performance
11 . Reasons and prevention measures for hollowing or decreased bonding strength of ceramic tiles after bonding
1) Pre leveling;
2) Adopting the combination method for construction.
How long after waterproofing construction is generally completed can tiling and joint filling begin?
Depending on the type of waterproof material, the basic principle is that the waterproof material must meet the strength requirements for tiling before tiling can be carried out. After tiling, the tile adhesive bonding strength must meet the requirements (usually 3-5 days) before jointing can be carried out.
How long after the completion of tiling and joint filling in general can it be put into use?
After filling the joints, it can be put into use after natural curing for 5-7 days (which should be appropriately extended during winter and rainy seasons).
