Tile water absorption rate is not as high as possible
In recent days, some netizens have shared their concerns about tiles in their newly renovated kitchens falling off within a year. After speaking with industry professionals, it became clear that this issue is often linked to the tile’s "water absorption" problem.
The author visited several major tile stores in Zhongshan and noticed that most consumers rarely ask about the water absorption rate when purchasing ceramic tiles. While store staff do provide detailed information on product specifications, many buyers overlook this crucial factor. So, what exactly is water absorption, and how does it affect the quality of the tile and the overall home? Is a higher water absorption rate always better? To find out, the author spoke with experts in the field.
Water absorption refers to the tile's ability to absorb and retain moisture. It is measured as the ratio of the weight of water absorbed by the tile to the weight of the dry tile itself. A low water absorption rate typically indicates a denser, stronger tile with greater internal stability. On the other hand, a high water absorption rate can lead to expansion, cracking, and even tile detachment. For example, if tea spills onto a high-absorption tile, the stain may seep into the surface and be hard to clean. This clearly shows how important the water absorption rate is in determining the quality of your renovation.
Interestingly, the thickness of the tile has no direct correlation with its water absorption rate. Different types of tiles—such as glazed, polished, and antique tiles—have varying water absorption levels. Polished and antique tiles are generally harder and more wear-resistant, making them ideal for flooring, while glazed tiles tend to have higher absorption. Therefore, it's not accurate to assume that thicker tiles automatically have better water absorption.
Many consumers lack awareness about the significance of water absorption. According to Mr. Zhao, a salesperson at Fuyi Decoration Plaza, most buyers focus only on the brand, and even sales staff rarely mention the water absorption rate unless asked. “If customers don’t inquire, we don’t go into too much detail,†he said.
To avoid purchasing low-quality tiles, experts recommend being cautious during the buying process. Here are five practical tips:
1. **Look**: Check the color and flatness. Clear colors usually indicate better quality, and you should inspect for pinholes or imperfections.
2. **Listen**: Tap the tile gently. A crisp sound suggests a dense and high-quality tile.
3. **Measure**: Use a ruler or tape measure to check the dimensions and diagonal alignment of the tile.
4. **Scratch**: Scrape the tile surface with a hard object to test the hardness of the glaze.
5. **Test**: Observe the water absorption. Tiles with lower absorption rates are more stable and suitable for damp areas like bathrooms or kitchens.
By paying attention to these details, you can make a more informed decision and ensure long-lasting, high-quality results in your home renovation.
