There are many netizens wondering why they have to leave seams when laying tiles.
In fact, it is very important to leave the seams on the tiles. Whether the tiles belong to "seamless bricks" or "round-edged bricks", paving requires stitching! The main reasons are as follows:
1) The problem of thermal expansion and contraction of ceramic tiles: There are problems of thermal expansion and contraction of ceramic tile and cement mortar bonded with tiles. In the course of temperature or moderate changes, there will be some expansion and contraction of ceramic tile and cement mortar, if no seam is left. , It will cause drums to crack or crack during the later use.
2) There are errors in tiles: Although the tiles are now mechanized, there are certain dimensional errors in the process of product production. (If the error is too large, it belongs to the quality of the product.) If there are no seams, it will easily appear. The seams on the tiles are uneven and affect the appearance of the tiles.
3) There is an error in the construction of the construction workers: The tile is a construction project with a high level of proficiency. During the entire process of laying, it is impossible to completely complete the installation of each brick without any error. Workers' bad moods, daytime and nighttime, etc. Tiles that are tiled under different conditions will have different effects. If no seams are left, it will be difficult to ensure that the seams of the tiles will be straightened and the tiles will be affected. Did not care!

So when does the tile jointing work better?
The answer is that it is advisable to dry the tile after it has been dried. Generally, the time for jointing is better when the tile is tiled for 24 hours.
If the tiles are not fully dried, the problems are: First, the tiles are uneven, and the second one is the looseness of the tiles. In this way, the tiles can easily fall off during the later use.
When performing the jointing of tiles, first of all need to clean up the dust and impurities in the tiles, then squeeze the grout into the brick seams, pay attention to the time of filling, be sure to squeeze full fill, after the jointing, timely Clean up the seaming material on the brick surface!
The problem has come again, and some netizens will find that the grout of the tile is blackened or even peeled off, which will greatly reduce the effect of tile tiles that should be beautiful.
The main cause of the blackening of the tile grout is due to the poor quality of the grout, its poor water resistance, and the infiltration of dirt into the grout.
The main reason for the separation of the grouts is the lack of adhesion of the grouts.
Encountered seaming agent black or off, in this Xiaobian put forward some simple ways to solve, for reference only:
Method one: scrape off the original tile caulking agent using a spatula (general building materials market hardware stores, paint shop building materials supermarkets) to scrape, re-use a good quality caulking agent for jointing, and other caulking agent After drying, the white candle is applied at the position filled with the caulking agent to enhance the water resistance of the caulking agent. The grouts are dirty and can be cleaned with toothpaste or detergent.
Method 2: The original grout can be scraped off and then jointed with US grout (a new type of water-resistant caulking material). US Grout It is a new generation of sealant. Its decorative and practicality is obviously better than that of color caulking agent. The new type of grouting agent does not require the sealant as the bottom layer, and can be directly added into the gap of the tile after the ceramic tile is bonded. Suitable for gap filling of more than 2mm, construction is more convenient than ordinary type.
