Tile water absorption rate is not as high as possible
In recent days, some netizens shared their experiences of moving into a new home just under a year ago, only to find that the kitchen wall tiles had started peeling off. After consulting with industry experts, it turned out that the issue was related to the tile's "water absorption" problem.
The author visited several major tile stores in Zhongshan and noticed that very few customers asked about the water absorption rate when purchasing ceramic tiles. Although store staff provided detailed product information, including the water absorption rate, many buyers remained unaware of what this actually meant. So, what exactly is the water absorption rate? How does it affect the tile’s structure and the overall condition of your home? Is a higher water absorption rate better or worse? To get answers, the author spoke with professionals in the field.
It's important to understand that the thickness of a tile has no direct correlation with its water absorption rate. According to Miss Fan, “Water absorption rate refers to the tile’s ability to absorb and allow water to penetrate. It is calculated as the ratio of the weight of water absorbed by the tile to the weight of the dry tile.†She explained that a low water absorption rate typically indicates a stronger, more stable tile that is less likely to swell or crack. On the other hand, a high water absorption rate can lead to expansion, cracking, and even the detachment of wall tiles or hollowing of floor tiles.
For example, if tea is spilled on a tile with high water absorption, the stain may seep into the surface and be difficult to clean. This clearly shows how crucial the water absorption rate is for the quality and durability of your home’s decoration.
If the water absorption rate is too high, tiles may fall off after installation. Conversely, if it's too low, improper spreading during installation could cause the tiles to peel. Therefore, choosing the right balance is essential.
There is a common misconception online that thicker tiles have better water absorption rates. However, Miss Fan clarified that this isn’t necessarily true. Tiles are generally categorized into glazed, polished, and antique types, each with different water absorption rates. Polished and antique tiles used for flooring tend to be harder and more wear-resistant, which means they usually have lower water absorption. But again, the thickness of the tile doesn't determine its water absorption rate.
Many consumers lack basic knowledge about water absorption, despite its significant impact on the appearance and functionality of their homes. Mr. Zhao, a salesperson at Fuyi Decoration Plaza, noted that most buyers focus on the brand rather than the technical specifications. Even salespeople often don’t emphasize the water absorption rate unless customers ask directly.
To avoid purchasing substandard tiles, industry insiders suggest following a few key steps. First, don’t be misled by discounts or promotions. Always test the tiles before buying. Here are five practical tips:
1. **Look**: Check the color and flatness. A clear, uniform color is preferable. Inspect the surface for pinholes, which can trap dirt.
2. **Listen**: Tap the tile lightly. A crisp sound indicates high density and quality.
3. **Measure**: Use a ruler or tape measure to check the dimensions and diagonal lines for accuracy.
4. **Scratch**: Scrape the tile’s glaze with a hard object to assess its hardness.
5. **Test**: Observe the water absorption. Tiles with low absorption are more stable and suitable for moist areas like bathrooms or kitchens.
By being informed and careful, you can make smarter choices and ensure long-lasting, high-quality results for your home.
