Common Tile Paving Problems and Solutions

2021.05.14 / By hqt

In people’s impression, ceramic tiles should be durable products, and there should be no problem after ten years of use. But in fact, some ceramic tiles become very dirty shortly after being laid, and some have cracks and hollowing. Is the quality of the tiles too poor or is the decoration company improperly paving?

Many people have encountered this kind of trouble. What is the cause of the cracking, abrasion, and cornering of the ceramic tile? Cracking, hollowing, or falling off of the ceramic tile is the most serious problem that may occur in the ceramic tile. , There are mainly the following incentives:

The wall does not meet the paving requirements

The tile cracks caused by wall deformation will show regular cracks in horizontal, vertical, or diagonal directions. After the lightweight wall is built, directly paving ceramic tiles and other decorative materials, it is very likely that settlement will occur, causing the wall to deform, causing the tiles to hollow, crack, or even fall off. Paving tiles directly on the insulation layer on the inner side of the insulation wall will also cause the tiles to hollow, crack or fall off due to the deformation of the wall.

Preventive measures: For walls that do not meet the requirements for paving, such as light-weight wall cracks, installation is not firm, deformation, wall peeling, cracking, etc. The home improvement company will remind the owner to find the developer or the property that is unqualified before laying the tiles To carry out rectification.

Secondly, it is recommended to make a layer of steel mesh on the side of the wall tiles to improve the strength and load-bearing capacity of the wall. For the insulation wall, the insulation layer is usually made of polystyrene board material, which can save the original insulation Remove the wall and replace it with bricklaying (commonly known as foam brick).

Due to the strong adhesion of the bricklaying, it can effectively reduce the cracking and falling of the tiles, but the insulation effect will be slightly worse. You can also hang a layer of steel mesh on the polystyrene board, and then use a cement pressure board or glass wave magnesium Board, on which tiles are laid.

Adhesive quality problem

Unqualified adhesives can also cause problems such as hollowing and falling off after tile paving. Traditional tile paving usually uses cement mortar as the adhesive, and 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 is too high, and the use of inferior or expired cement will lead to insecure bonding and cause the tiles to hollow and fall off.

Preventive measures: Remind the majority of owners to use regular home improvement companies and qualified craft materials. The current thin paste method not only saves space, but also has convenient construction and higher bonding strength, but the price is relatively expensive, and the owner can choose to use it.

The tiles are not soaked in water

Preventive measures: Use cement mortar to pave the tiles (mainly referring to wall tiles). The tiles need to be soaked in water for about two hours in advance. The higher the density of the bricks, the better the quality, and the shorter the time required for soaking. The thin paste method does not need to be soaked. The proportion of the paste contained in the mortar used is relatively large, and the water retention is extremely strong.
