I.Polished tilesWhat could cause it to peel off?
once the polished tiles are laid, they may start to peel or detach. This is usually due to air pockets forming within the tiles themselves. There are two primary causes for this: settling of the building foundation and temperature fluctuations (expansion and contraction).
Polished tiles can be divided into two categories: fully arched and partially arched. If the tiles are fully arched, you can remove them one by one and label each tile with a number to easily remember their original positions. Maintain the original orientation of the polished tiles. Then, remove all the cement mortar attached to the edges of the tiles. Clean the original surface with a dry cloth and apply wood glue to the substrate. Finally, arrange the tiles according to the numbers and press them firmly. To repair a square meter of polished tiles, approximately one kilogram of wood glue is required.

If only a portion of the arch is raised, some polished tiles can be easily removed, while others cannot. Tiles that cannot be removed should not be forcefully pried, as this will cause them to break. In such cases, a cutting machine is required. The cutting machine should be used to cut along the seams of the polished tiles. Each tile has four edges, and the number of cuts required will depend on the specific situation. In some cases, all four edges may need to be cut, while in others, only two edges may be sufficient. After cutting, it is generally recommended to wait for one to two hours, during which time the raised tiles will naturally collapse. The cutting process will generate a large amount of dust, so it is necessary to continuously add water to the cutting machine.
Two. How to handle deformation of polished bricks.
1、 Deformation caused by improper use of the space.
Polished tiles are prone to staining and are therefore generally not used in kitchens or bathrooms. For those unfamiliar with the characteristics of polished tiles, installing polished tiles in bathroom spaces can lead to tile deformation. In general, the most common type of tile deformation in polished tiles is a "flagstone" or "arching" pattern. This is primarily due to moisture absorption. The main reasons for moisture absorption in polished tiles include:
- Humidity in the air (e.g., humid days);- Un-dried ground floor;- Concrete-reinforced floor joists;- Tiles that are too wet, using water-based adhesives;- Unaddressed moisture control in areas with high humidity;- Unsealed joints between stone flooring and polished tiles;- Water blisters (e.g., water leakage from pipes, water overflow on balconies).
2、Poor-quality cement used during construction leads to deformation.
- Use adhesives appropriately. Minimize the use of wet laying when geothermal heating is present. Follow regulations for laying polished tiles, including proper spacing. After installation, continue to ventilate, especially in lower-level rooms with eastern-facing windows. National and industry standards require dehumidification measures when humidity reaches 70% or higher to prevent moisture damage. Polished tiles are natural materials and may exhibit minor gaps, warping, or color changes during use, which is normal. Minor noise, paint chipping, or cracking are also unavoidable.
According to national standards, after installation, the substrate must be inspected within three days. It is recommended that the owner keep a sample of the original, unpolished tiles. This allows for clarification if any questions arise later, as the inspector can determine whether the issue is with the tile quality or the installation quality. once the tiles have been installed, it is impossible to determine whether the issue lies with the tiles themselves.
