The difference between tile adhesive and tile back coating
As people have higher and higher requirements for the quality of home decoration, ceramic tiles are one of the important materials for home decoration, and the selection of pasting materials is also particularly important. Tile adhesive and tile backing glue are two common adhesive materials, but there are some distinct differences between them. This article will detail the characteristics and usage methods of these two materials to help you better understand their differences, so that you can choose a more suitable material for yourself when decorating.
1. Tile adhesive.
Tile adhesive is a dry powdery adhesive material based on cement, which mainly sticks tiles to the wall through adhesive force. Its advantages lie in strong adhesion, small shrinkage, high stability, and are suitable for various types of tiles and substrates. At the same time, the construction of tile adhesive is relatively simple, just mix the dry powder and water according to the ratio of the instructions, apply it to the back of the tile, and then stick it on the wall.
However, there are also some drawbacks to tile adhesives. First of all, it needs the wall surface to have a certain flatness and humidity, if the wall surface is too wet or uneven, it may cause the paste to be not firm. Secondly, the adhesive thickness of the tile adhesive is large, which is easy to occupy the indoor space and is not easy to adjust. In addition, tile adhesives take a long time to cure and take a certain amount of time to achieve the desired bond strength.
Second, the back of the tile is glued.
Tile back coating glue is a kind of adhesive material specially used on the back of ceramic tiles, mainly by forming a layer of colloidal substance on the back of the tile to increase the adhesion between the tile and the adhesive material. Its advantage is that it can greatly improve the adhesion between ceramic tiles and adhesive materials, and effectively solve the common problems of hollowing and falling off in ceramic tile wet pasting. At the same time, the back coating of ceramic tiles can also reduce shrinkage and improve the stability of the paste.
In contrast, the application of ceramic tile back glue is more complex. Before use, you need to clean the back of the tile and apply an appropriate amount of back glue. Wait for the backcoat to dry before attaching it to the wall. Since tile backing requires the formation of a layer of gum on the back, it is necessary to ensure sufficient application volume and uniformity. In addition, tile backing needs to be applied in a suitable environment to avoid adverse conditions such as humidity and high temperatures.
To sum up, tile adhesives and tile back coating adhesives have their own characteristics and scope of use. Tile adhesives are suitable for various types of tiles and substrates, but require moderate wall flatness and humidity; The back coating of ceramic tiles can greatly improve the adhesion between ceramic tiles and adhesive materials, reduce shrinkage, and improve stability, but it needs to be constructed in a suitable environment. Therefore, when choosing a pasting material, you need to choose according to the actual situation. At the same time, in order to ensure the sticking effect and the safety of the indoor environment, it is recommended to choose products with high brand awareness and reliable quality.
