Many owners will have doubts when decorating, don’t tile paving already advocate seamless paving? Why do the decoration masters recommend that tiles be laid with seams? Is it better to pave seamlessly or to leave seams during decoration?

One: Is it possible to pave tiles without leaving seams?

The answer is no. Tiles must be laid with seams. No matter what specifications and grades of tiles, there will always be a certain difference in length, width, height and thickness. If no seams are left, the effect of the paste may be crooked. There is also the influence of thermal expansion and contraction. Even if the ceramic tiles are not affected much, they still have to follow the laws of nature, so it is necessary to leave seams.

2. Why should there be seams in tile paving?
1. The characteristics of thermal expansion and contraction of ceramic tiles

Ceramic tiles and cement mortars for pasting tiles will have thermal expansion and contraction problems. In the process of temperature or humidity changes, ceramic tiles and cement mortar will expand and contract to a certain extent. If no seams are left, the tiles will be used in the later process. Drums or cracks appear.

2. Tile repair is more convenient
Leaving the pavement can make future maintenance and maintenance more convenient. For example, due to human reasons, a heavy object accidentally falls and damages the tiles. If the seams are left, the damaged tiles can be easily replaced.

3. The ceramic tile has errors
Although ceramic tiles are now mechanized production, there will be certain dimensional errors in the production process (excessive errors belong to the quality of the product). If no seams are left, it is prone to joints during tile laying. Uneven seams affect the appearance of tiles.

4. Errors in construction
The paving of tiles is a construction project with a very high level of proficiency. During the entire paving process, it is impossible for workers to completely pave each tile without errors. If no seams are left, it is also difficult to ensure the straightness of the joints of the tiles, which will affect the aesthetics of the tiles!

5. The tiles will be more beautiful if they leave the seams

The regular lines formed by the paving of the tiles can achieve a certain three-dimensional effect. At the same time, its function can not only beautify the overall paving space, but also relieve visual fatigue to some extent.

Three: the choice of caulking materials

1. Grout
Advantages: strong adhesion, resistance to pressure, reduction of shrinkage, wear resistance, flexibility to prevent cracks, and lower price.

Disadvantages: The color is relatively dim, it is easy to be dirty and black during construction and use, the strength is low, and the powder is not waterproof. Odor and mold will be produced in wet places such as bathroom and kitchen gaps after water seepage.

2. Beauty sewing agent
Beauty seam agent is a new type of organic material, which is mainly made of high-tech polymer, high-grade pigments and special additives.

Advantages: bright colors, high gloss, suitable for matching with various color tiles. It has the characteristics of waterproof, impermeability, non-sticky oil, and it is not easy to get dirty and black and mold.

Disadvantages: low hardness, thin protective layer, and high price.



Fourth, the precautions for laying tiles

1. Tile gap size

Generally, the remaining seam of seamless bricks should be 1-1.5mm, but not less than 1mm. Ordinary tiles are roughly between 3 and 5mm. In addition, the best standards that should be adopted during construction are also determined according to actual factors such as the type of brick and tile, the size of the specification, and the overall area of the paving.

2. Paving the cross with seams
The tile cross can make our laid tiles look more regular and beautiful in appearance than the tiles without the tile cross, because the tile cross can make the gap between the tiles uniform and even, which can adjust the size of the gap between the tiles. Make the overall appearance of the tile laying look neat and beautiful.

When buying ceramic tiles, you can ask the seller for the special cross locator (width 1mm, 2mm, 3mm, 5mm, etc.) to ensure that the tile joints are straight and even in size.





3. Widening
It is also possible to widen the tile gaps when laying tiles for special effects. For example, it is advisable to leave wide seams for antique bricks, exterior wall bricks, cultural bricks, etc. with special effects. In addition, if the tiles are laid in winter, pay attention to slightly larger seams to prevent thermal expansion and contraction, and the caulking will squeeze each other.

4. Filling the tiles after 24 hours
In order to avoid movement caused by the tile paste is not yet firm, it is safer to wait 24 hours before proceeding with the caulking treatment.

5. Process treatment of caulk
Before caulking, you need to clean up the dirt in the gap first: the mixing ratio of caulk and water is 1:1 to evenly stir to caulk the joints to avoid scratching the tiles due to the large particles in the caulk; caulking should be done while caulking Clean, remove excess caulk sticking to the tiles, to avoid that it is difficult to clean after drying; after the caulking work is completed, further cleaning of the surface of the tiles is required.



The above question about leaving no seams for tile paving has already been answered. The conclusion is that tiles must be laid with seams. In addition to ensuring the quality of tile paving, leaving seams and paving can also make the home more beautiful, especially It is under the condition that there are endless beauty seam agents. Will there be seams in your tiles?
