Mosaic tile paving is an important part of the decoration. Some owners pay great attention to the tile paving process and quality. When paving tiles, there is a lot of controversy from the traditional use of cement as the base material to the use of tile glue. The traditional cement process makes the owner feel more secure, but some people have pointed out that the tile adhesive performance is better. Next, I will introduce to you which tile adhesive and cement are better in the mosaic tile laying.
Characteristics of ceramic tile glue
Tile adhesive is also known as ceramic tile adhesive. As a new type of decoration material, it is mainly used for pasting surface tiles, tiles, floor tiles and other decoration materials, and gradually replaces traditional cement yellow sand. Tile adhesive is easy to construct and has good flexibility. It can effectively prevent tiles from hollowing out. It has high bonding strength, water resistance, freeze-thaw resistance, and aging resistance. The adhesive strength of tile adhesive is several times that of cement mortar. A very ideal bonding material.
Comparison of advantages between ceramic tile glue and cement
To cement-based shop pastes easy to cause ceramic tile hollow, falling and other problems, to rough surface, porous and high water absorption rate of ceramic tile paste to ensure firmness. Tile Glue can not only solve these problems, compared with cement, it is more space-saving, in the construction process only need a thin layer. There are a lot of tiles on the market smooth surface, low water absorption, choose tile adhesive pasting more appropriate.
As mentioned above, we can conclude that using mosaic tiles is better than using concrete river sand. The adhesive strength of the tile adhesive is more than three times that of the cement river sand. In addition, the steps of wet walls, soaking tiles, and fixed supports can be omitted during construction, and the construction can be performed by adding water in proportion.
Type and brand of tile adhesive
In the process of using tile adhesive for mosaic tiles, the type of tile adhesive is also very important. Tile glue is divided into No. 1 (ordinary type), No. 2 (enhanced) and No. 3 (larger size tiles or marble). Among them, No. 1 tile adhesive is suitable for the pasting of various ground bricks or small bricks on the ordinary mortar surface; No. 2 tile adhesive has strong adhesion and anti-sag performance, which is suitable for the requirements of adhesion Large wall tiles, non-mortar surfaces such as wood board surface or old finish.
Tile adhesive No. 3 is suitable for the mosaic tile laying. It has a large adhesive force and is more flexible. It can withstand the stress caused by thermal expansion and contraction of the adhesive layer. Finishing (tiles, mosaics, terrazzo), etc., as well as the pasting of various large-scale stone plates. In addition to gray, tile adhesive can also provide white appearance, suitable for light or translucent marble, tiles and other natural stone.
The brands of tile adhesives include JCDecaux, Leibangshi, Mapei, Sika, Henkel, Oriental Yuhong, Duobang, Elaide, Deanmi, Longma, etc.
Construction method of tile adhesive
Clean the construction surface first, and keep the surface firm, dry, clean, and free of stains. Stir the tile glue in water to form a paste, the ratio is 25 kg, add water to about 6 to 6.5 kg, and stir for 10 minutes. Stir it a little and use it for about 2 hours. Do not reuse the dried glue.
The tooth-shaped scraper spreads the glue on the wall, evenly distributed about one square meter, and then presses the tile on it in 15 minutes or so (if adjustment is needed, the tile glue is not fixed).
Pay attention to keep the expansion joints. The product is suitable for use in the environment of 5 ℃ ～ 40 ℃. It can be stepped in or filled after 24 hours. If it is cured for more than 24 hours, the stains on the tile surface can be cleaned with tile stone cleaner (do not use acid cleaner). Before application, the verticality and flatness of the substrate must be confirmed. Do not mix the dried glue with water before use. Pay attention to the expansion joints.
