Upstairs, all I can say is that you're really good at chemistry, hehe!
You have too many mistakes, don't say no: the main component of limestone and lime powder is calcium carbonate (CaCO3), not Ca2CO3, not CaO, CaCO3 and air CO2 contact can not form CaO, must go through high temperature calcination to produce lime, that is, CaO, also called quicklime, quicklime (Cao) is very unstable, and reacts with water to form calcium hydroxide Ca(OH)2, called hydrated lime.
Back to the landlord's question.
There must be a problem with the operation of the plastering master, he is to replace the sand with lime powder into the white cement, and the role of the sand in the cement mortar is by no means the role of lime powder can be replaced, and it can not enhance and improve the hydration of cement and the compactness and strength, which is definitely not good for the adhesion of ceramic tiles.
-
Yes, cement can make the tile fix quickly, and the main component of lime is Ca2CO3, which will form Cao after contact with the CO2 of the air, which is the main component of what we call limestone, which is very strong. Generally, the oxidation resistance of cement is about 60 years, and the oxidation of lime is very long, and its service life is longer than that of cement.

Don't worry, this is mainly to consider that there is no need for hooks, there is no problem.

Absolutely, they're experts.

Don't worry, he should be using fast sticky powder.

The white ash of the original wall is generally for tempering putty and anti-fouling. It is necessary to remove the topcoat and putty layer to expose the cement mortar layer before the wall can be treated with a mosaic tile surface treatment agent, and then the tile adhesive can be used to apply the tiles.
If it is tempered putty painted before, talcum powder will generally be added. If you rush to put bricks up at this time, the possibility of falling off the wall tiles in the later stage is too great. If you don't want to dispose of it, you can use glue and interface agent on the wall to plaster a layer of plaster, the surface must be as rough as possible, and you can paste it after drying, and the bottom layer of the tile must be firm.
Note that the wall tiles on the white ash wall, the wall should be wet with more water, and then a layer of cement paddle should be filled, and some construction glue should be added to the cement slurry, which can avoid the cement slurry drying too quickly, and the next day can be operated according to the normal wall tiles.

First of all, you have to confirm whether it is white cement, white cement is generally not used to make indoor walls, one is not good strength, and the other is more toxic.
White cement is used to make exterior walls and scrape tile joints more. So it may be an ordinary putty scraped white. If it is white cement, insurance, first knock and then scrape, scrape it can not be scraped down with a grinder, although it is troublesome, the insurance tile will be stable in the future.
If it's putty, water it and scrape. That's it. Putty must be scraped, if it is white cement, the requirements are not high, you can not scrape.
The tiles will not fall off in a few years.
-
If the white cement is not affected, it can be pasted directly without scraping.
-
It is better to clean the wall, it will really fall off after a long time if it is not clean, and the wall should be brushed with glue, waterproof, and easy to adjust.

Summary. Hello, you need to remove the topcoat and expose the cement mortar layer before you can treat the wall with mosaic tile surface treatment agent, and then use tile adhesive to paste the brick.

I hope mine can help you

The white cement wall cannot be directly tiled, and it is easy to fall off after drying.
It is necessary to shovel off the white cement or beat the hair, which is to increase the friction, so that it is not easy to fall. It's like sticking a hook, the surface is too smooth and easy to fall off. You have to get some water in it.
White cement is the abbreviation of white Portland cement, white cement is mostly used for decoration, and its manufacturing process is much better than ordinary cement. It is mainly used to hook the gaps of white porcelain tiles, and is generally not used on the wall, because the strength is not high. Therefore, it is not recommended to put tiles directly on the walls of white cement.

No. The use of tile adhesive has more space saving than the use of cement, and tile adhesive only needs a thin layer during the construction process. The tile is very firm, without any toxic additives, in line with the environmental protection and health requirements of the bridge hail.
Tile adhesive construction is to maintain the wetness of the wall, and to ensure a certain flatness, the base needs to be necessary to remove floating ash, wax, oil and other treatments, so as not to affect the degree of adhesion. It is precisely these advantages that make tile adhesive widely used instead of cement mortar.
However, why do so many construction sites use tile adhesive mixed with cement? The most important part is to save money or cut corners, the current cement market price is cheaper than tile adhesive, which many masters in the treatment of ceramic tiles on the wall, pasting the situation, it is natural to think that the previous use of cement is fine, now the use of tile adhesive will be better, add some cement is no problem, it is precisely because of this psychology, now the phenomenon of turning, hollowing is not uncommon, most of the owners will think that the quality of the tile adhesive brand is poor, but they do not know that the halfway has been unrecognizable.

1) The wall should be carefully cleaned before construction, and it should be watered and moistened the day before.
2) Cut one end of the corner corner base according to the desired amount, cut it to 45° with a toothless saw, wash the base with water and dry it in the shade.
3) When assembling, start from the front to both sides, and check whether it is straight, whether the separation is narrow, whether there are missing corners, etc.

4) Regardless of the method used for installation, first place the base at both ends of the wall. The height of the top edge must be on the same horizontal line and the wall thickness must be the same. Then, the two upper sockets are installed one by one along the tow line, in order.

2. Construction methods.
1) Gluing method. According to the standard ribs of the wall and the standard horizontal line, the bottom ash is stained with 1:cement mortar and the stroke is smoothed.
After the lower mortar is dry and hard, the wet and dry tiles are applied to a smooth cement slurry of 2-3 mm for bonding. Gently pat with a rubber mac and use a ruler to level and straighten at any time. The next day, the joints are cleaned using a cement slurry of the same color as the floor.

2) Grouting method. Temporarily fix the tiles in the installation position, stabilize the two adjacent tiles and tiles with plaster with the floor and walls, then apply the grout with cement mortar 1:2 (volume ratio) with a consistency of 10-15 cm and wash the poured mortar at any time.
After the final insertion of the cement mortar to be poured, the plaster is scraped off and cleaned, and the cement is rubbed with the same color as the surface of the slab.

Precautions for tiling.
The tiles must be pasted flatUnder normal circumstances, after the master has laid the tiles, he will use a plastic hammer to beat the surroundings to control the flatness of the tile surface in time. If the master does not inspect it, it will not help to wait until the cement is dry. Therefore, the owners should also pay great attention to this aspect.
Tiles are well pasted to measure verticallyOwners should pay attention to check whether the master has carefully measured the verticality of each tile pasted, the main purpose of which is to ensure that all the tiles are like a big glass adsorbed on the wall. If it is a master who is not in place, he will pick up the tile and paste it, and will not investigate the size and appearance of the tile at all.
The tiles must be glued firmlyWhen the master and friend have laid the tiles, the owners must check how firm the tiles are. Because there are some careless masters who apply the false silver of the tile, the edge of the tile is not filled with cement, which eventually causes the tile to fall off. We all know that it is a very troublesome thing to fill in after the tiles have fallen off, so the owners must be cautious in this regard.
