Seams in ceramic tiles are a detail that cannot be ignored during the paving process, and directly affect the aesthetics and service life. Combined with the hot topics on the Internet in the past 10 days, this article will conduct a structured analysis of seam-retaining techniques and attach relevant data comparisons.
1. Why leave a seam?
1.Thermal expansion and contraction: Ceramic tiles will be slightly deformed due to temperature, leaving seams to avoid extrusion cracking.
2.construction error: There are slight deviations in manual paving, and leaving seams can cover up unevenness.
3.Aesthetic needs: Reasonable gaps can enhance the sense of layering, especially the “narrow gap” design (a hotly searched keyword recently) is popular.
| Seam type | Recommended width (mm) | Applicable scenarios |
|---|---|---|
| wall tiles | 1.5-3 | Bathroom and kitchen walls |
| floor tiles | 2-5 | Load-bearing areas such as living rooms and balconies |
| Large format ceramic tiles | 3 or more | 750x1500mm and other large boards |

|---|---|---|---|
| minimalist style | 1-2 | same color system | ★★★★★ |
| retro style | 3-5 | Contrasting colors (such as white bricks + black seams) | ★★★☆ |
| microcement effect | Seamless processing | Epoxy colored sand | ★★★★ |

Q: Do seamless tiles really require no seams?
A: A gap of 0.5-1mm still needs to be left. The so-called "seamless" is just a visual concept. The manufacturer clearly indicates that expansion space needs to be reserved.
Q: How to choose a seaming agent?
A: Recently, the number of searches for environmentally friendly water-based epoxy resin caulking agents has soared. Compared with traditional porcelain caulking agents, the data is as follows:
| Type | Durability | Environmental protection | Price(yuan/㎡) |
|---|---|---|---|
| Water-based epoxy resin | 8-10 years | Formaldehyde-free | 25-35 |
| Oily porcelain caulking agent | More than 10 years | Contains VOC | 15-25 |
5. Expert advice
The August 2023 report of the China Ceramics Association stated:
• It is recommended to leave a gap of ≥2mm for 600x1200mm ceramic tiles
