9 questions that often appear in tile paving
Tiles are a popular choice for home decoration, often used to cover floors and walls. The quality of tile installation plays a crucial role in the overall success of a renovation project. To help homeowners avoid common mistakes, we’ve compiled nine typical issues that may arise during tile laying, along with explanations and solutions.
1. **Why do wall tiles sometimes fall off soon after installation?**
When installing wall tiles, cement mortar is commonly used as an adhesive. However, if the wall bricks have high water absorption and aren’t soaked beforehand, the ceramic tiles can absorb moisture from the cement mixture. This weakens the bond, leading to poor adhesion and eventual detachment of the tiles.
2. **Why should gaps be left between tiles when laying them?**
Leaving small gaps helps accommodate minor dimensional differences in the tiles and prevents damage caused by thermal expansion and contraction. Without these gaps, tiles may push against each other, resulting in cracks or lifting.
3. **What is the recommended gap size for different types of tiles?**
Polished tiles usually require 1mm gaps, regular tiles need 2–5mm, and antique-style tiles typically require 5–8mm.
4. **Why might the pattern not look as expected after tiling?**
Many tiles have directional patterns or logos on the back. Laying them consistently in the same direction can enhance the visual effect and create a more cohesive design.
5. **Should pure cement be used for tile installation?**
It’s better to use a 1:3 cement mortar mix with low-grade cement (325 or below) rather than pure cement. This reduces the risk of shrinkage, which can cause cracks in the tiles.
6. **Is it safe to cover tiles with packing boxes during construction?**
No, this practice is not advisable. Packing materials can dissolve in water and release bleaching agents that stain the tiles. Instead, use woven bags or other non-staining materials to protect the surface.
7. **Why do polished tiles show color differences after installation?**
Color variation can occur due to lighting conditions, mixing tiles from different batches, or improper grading at the factory. It's important to check the color numbers on the packaging before installation.
8. **Should wall tiles be laid horizontally or vertically?**
The choice depends on the space’s dimensions and personal preference. In small rooms with high ceilings, horizontal tiling can make the space appear larger. Vertical tiling is ideal for short spaces, helping to visually extend the height.
9. **Why are some tiles laid without proper seams?**
This often happens when tiles of different sizes are installed on the same plane. Proper planning and measurement are essential to ensure even spacing and a neat finish.
By understanding these common issues, you can achieve a better result in your tile installation and enjoy a beautiful, durable finish.
