An important use of redispersible emulsion powder is tile binder, and redispersible emulsion powder is widely used in various tile binders. There are also various headaches in the application of ceramic tile binders, as follows:
Ceramic tile is fired at a high temperature, and its physical and chemical properties are very stable, but why does it still fall off after tile placement?
In fact, most of the reasons are not caused by the quality of the tile itself, but more likely because a certain process of the tile in the construction of the tile is not well controlled. The following are several specific reasons causing the tile to fall off directly:
1. The tile is not soaked or soaked enough before the tile is laid. The tile that is not soaked or soaked enough will absorb the moisture of the mortar on its surface, reducing the bonding force, and the tile can be soaked at any time.
– 2. Before construction, there is too much water on the surface, and too much water will be left between the tile and the mortar when pasting, and once the water is lost, it is easy to lead to empty drums.
– 3. The base plaster treatment is not good –
The base plaster is not treated as required or the base dust is not cleaned up, and the moisture in the mortar after tile placement is absorbed by the base or dust and other sediments, which affects the bonding quality of the tile and the substrate and produces a hollow drum or falling off phenomenon.
– 4. The tile bond is not firm –
Different bonding strength and shrinkage between the ceramic tile and the base, resulting in empty drums and even delamination, due to the emergence of a lot of large tiles in recent years is very popular, tile area with a rubber hammer to beat the leveling is difficult to eliminate all the air of the tile adhesive bond layer, so it is easy to form a hollow drum, the bond is not firm.
– 5. Tile pointing problem –
In the past, many decoration workers used white cement to caulk, because the stability of white cement is not good, the quality duration is short, after a long time, the phenomenon of leakage leads to the bonding between the caulk and the tile is not firm, the wet place will change color and dirty, and the water after the crack of the tile is easy to cause the subsequent fall off, the tile paste must have a gap. If the seamless paste will cause the ceramic tiles that change after being heated to squeeze each other, causing the porcelain to drop off the Angle or even fall off.
Well,
How to deal with empty tile drums when laying improperly?
– ① Lesser degree –
If the tile on the wall floor appears local slight empty drum, but does not affect the use, at this time, the empty drum tile has a cabinet board against the pressure tile is not easy to fall off, it can also be considered not to deal with, but if it affects the installation and daily life, or the empty drum position is prominent or the use rate is high, it is still necessary to knock off the local tile and re-lay according to the above situation.
– ② corner empty drum –
If the empty drum occurs at the edge of the four corners of the tile, the treatment method of filling cement slurry can be adopted, which saves time and effort and is not easy to cause damage to the tile.
– ③ empty drum in the middle of the tile –
If it is a local empty tile, the empty drum position occurs in the middle of the tile or there is still a empty drum phenomenon after the corner of the empty drum after grouting, it is necessary to remove the tile and re-lay it, this time you can choose to use the suction cup to suck the empty drum tile, lift it out flat, and then the empty drum tile is re-laid according to the specification.
– ④ Large area empty drum –
If more than half of the paving area has empty drums, it is necessary to pry off the entire surface of the tile to resurface, in general, this large area of empty drums is generally caused by improper construction, should be by the construction party to bear the cost of ceramic tile damage and artificial auxiliary materials.
– The empty drum falls off –
If the degree of hollow drum is more serious and the tile has completely loosened or even fallen off, it means that the cement mortar layer under the tile and the wall base have also loosened, at this time, you can use tools such as a shovel to clean up the cement mortar layer, and re-apply the cement mortar after laying the tile.
The selection of high-quality mortar additives can effectively solve the problem of ceramic tile bonding.
The use of redispersible emulsion powder in the ceramic tile binder can increase the anti-slip and adhesion of the ceramic tile binder, so that the use effect of the ceramic tile binder is significantly improved
