I am afraid that the tiles will fall off, and after brushing the wall, my friend still insists on do

I think it's necessary. Because the walls will be very smooth after brushing, it is definitely necessary.

It is necessary. Only when the surface treatment is particularly clean, it will be stronger when using tile adhesive for bonding.

I feel necessary. Because brushing can be done to make it firmer and prevent it from falling off again in the future.

When decorating and pasting tiles at home, I always see the decoration master pull and knock on the wall with a shovel or other tools, and only paste the tiles after the wall has grooves and roughness. After questioning, I learned that the masters were doing the wall brushing treatment, so that the contact between the tile and the wall could be stronger. The following should be pulled together, there seems to be no special requirements for the pasting of tiles, because the cement wall tiles at that time were not very smooth, with cement mortar directly paved tile line, some can directly choose tile adhesive, if it is a semi-finished product, the wall is very rough, you can also cancel this ceremony, but if it is a kitchen and bathroom, because to do waterproofing, waterproof wall scratching, do hair treatment, otherwise the tile will fall off due to poor pasting.

After the developer <> build the house, many people want to redo the waterproofing, if the wall is hairy after the new house, then the hair layer must be thoroughly cleaned, because it is not clear that the waterproof can not be brushed, so the hair has to shovel a sum of money, redo the waterproofing costs a sum of money, and then waterproof and tidy up the hair is a sum of money, so we should pay attention to the fact that if the developer does a good job of waterproofing, in my opinion, as long as the bottom of the wall is scraped off, and the ground is waterproof again. If you shave in such a large place, the cost will go up a lot.

It used to be possible to do waterproofing for free, but now it costs $10 to $15 per square meter. If the wall is already particularly dry and hard, you can use a cutter to draw a lot of grooves on the wall, which is the most reliable and practical method, and it can be directly attached to the tile after hair, which is generally very firm. Some decoration masters will use a broom to shake a few times, although labor-saving, but the plain cement slurry has not been dried on the tile, it is easy to appear hollow drum falling off, at least there must be a roll, at the same time with tile glue and cement slurry plastering, be sure to wait for the wall to dry hard, and then paste the tile.

I casually flicked the broom twice to pull the wall down softly, and only then pulled my hair down to the bricks. In order to reduce the hollowing phenomenon of wall tiles and prevent the tiles from falling off, it is necessary to do a good job of wool processing. Thank you for reading and subscribing.

It is very necessary, such as bathroom, kitchen and other humid spaces, it is necessary to paint the waterproof layer, and the waterproof layer has a certain degree of water repellency, if the tile is directly paved because of the lack of adhesion strength will appear tile off, and the brushing treatment is to enhance the roughness of the surface of the waterproof layer to improve the bonding strength of the cement mortar and the tile.

Is it necessary to brush the wall after brushing it?

There are many reasons for the cracking, hollowing and falling off of tiles in the later stage, such as: hollowing and cracking of the original wall, uneven wall surface and insufficient strength of the wall base. The original wall is hollow and cracked, and the whole wall needs to be reprocessed before paving the tiles, and the uneven wall needs to be leveled, and the strength of the wall base is not enough, so it is necessary to enhance the adhesion between the wall and the tile.

The role of brushing the wall solid.

1. The wall solid has solidified cement to prevent the cement from falling off, so as to solve some subtle problems such as loose and sandy common walls from the side. Moreover, the wall solid has a strong permeability and can enhance the adhesion of the wall on a certain basis.

2. The inherent function of the wall not only protects the original wall, but also does not affect the adhesion between the wall decoration material and the original wall.

Therefore, the general wall can be solved by painting the wall, and there is no need to do more than that, and then carry out brushing treatment to enhance the adhesion between the tile and the wall when laying the tile.

The role of brushing.

Like bathroom, kitchen and other humid spaces, it is necessary to paint the waterproof layer, and the waterproof layer has a certain degree of water repellency, if the tile is directly paved because of the insufficient bonding strength of the tile to fall off, and the brushing treatment is to enhance the roughness of the surface of the waterproof layer to improve the bonding strength of the cement mortar and the tile.

Therefore, even if the bathroom and kitchen are painted with wall solidification, it does not have much effect on the bonding strength between the tile and the cement mortar, so it is still necessary to do brushing treatment.

I think it's completely unnecessary, under normal circumstances, as long as your decorator has experience, he will give you a good tile will basically not fall.

If the original wall is a large white wall, the original wall must be brushed after the wall is solid, otherwise there will be hollowing and falling off after the tile is paved.

After brushing the wall, you can directly paste the tiles, because it is easy to fall, and you need to do a good job of waterproofing and brushing before you can paste the tiles. After waterproofing, you must do brushing, otherwise the tile will not be firmly pasted, and it will fall down after a long time. Some people say that the use of tile adhesive instead of cement mortar, that is, the so-called new thin paste method, does not need to do brushing treatment, such a statement is incorrect.

In addition, the brushing after brushing the wall needs to be dealt with, because the smooth wall tiles are not very stable and firm, otherwise the source of early laughter will affect the overall aesthetic effect.

This mainly depends on the specific situation, if there are serious sanding problems on the wall, do not paint the wall at this time, you need to carry out brushing treatment first, and then you can paste tiles.

No, if you brush, it is easier to make the tiles fall off, and the post-processing is particularly troublesome.

Of course, it needs to be brushed after the wall is painted, so that the whole wall will look more perfect, and the surface will be much less hairy, and it will not be easy to fall off.

It is best to do brushing, which will make the whole wall particularly strong, and the tiles will not fall off and be strong when they are inlaid on it.
