What are the factors that cause the cracking of tile beauty joint agent?

The technology of tile beautifying agent is constantly developing and updating with the current society, and the machinery and equipment of the beautifying agent are better now, and the equipment is perfect, so in terms of quality It has improved a lot, but as the season changes, the temperature of the floor is also hot and cold, especially in the north, where most homes are equipped with underfloor heating. It is very cold when it is cold, and the floor is very hot when it is hot. In the case of a large temperature difference, the beauty joint agent will crack. So what do you know about the daily maintenance of beauty joints?

1. Wall deformation

The cracking of tiles caused by wall deformation will show regular cracks in horizontal, vertical or diagonal directions.

Precautions: Before laying bricks on light-weight walls, first ask the construction staff to inspect the wall to see if the wall is firmly installed; secondly, it is recommended to make a layer of steel wire mesh on the side where the wall bricks are laid to lift the wall. Body strength and load-bearing capacity. For thermal insulation walls, the thermal insulation layer is usually made of polystyrene board materials. The original thermal insulation wall can be removed and replaced with bricks (commonly known as foam bricks). Due to the strong adhesion of bricklaying, it can effectively reduce the phenomenon of tile cracking and falling off, but the heat preservation effect will be slightly worse. You can also hang a layer of steel mesh on the polystyrene board, and then use cement pressure board or corrugated magnesium board to pave ceramic tiles on it.

2, the adhesive is unqualified

Unqualified adhesive can also cause problems such as hollowing and falling off after the tile is laid. Traditional tile paving usually uses cement mortar as an adhesive. The ratio of cement and mortar is usually 1:1. If the ratio is not uniform, the cement mortar will not achieve the required bonding effect; in addition, the sand content Too high, use of poor quality or expired cement will lead to inadequate bonding and cause problems such as hollowing and falling off of the tiles.

Precautionary measures: remind owners to use formal home improvement companies and qualified craft materials;

3. The tiles are not soaked in water

If the tiles with a certain water absorption rate are not immersed in water before paving, after paving the cement mortar will condense and the strength will increase, the tiles will absorb the water, which will cause the cement to lose water and lose the adhesion and the strength will decrease , The adhesion of bricks to cement or cement to the original wall is reduced, resulting in hollowing and falling off.

Precautions: Use cement mortar to pave the tiles (mainly referring to wall tiles), and the tiles need to be soaked in water for about two hours in advance. The higher the density and the better the quality of the bricks, the shorter the time required to soak in water. The thin paste method does not need to be immersed in water, and the proportioning mortar used contains a large proportion of the paste ingredients, which has extremely strong water retention.

Through the above introduction, everyone should have a certain understanding of the causes of tile cracking. In fact, the causes of cracking are more complicated, such as the gaps are not cleaned up, the adhesive strength of the beauty joint agent is insufficient, and the toughness is not enough, but most of them are caused by quality problems, and the beauty joint agent is quite good.
