How to choose tile glue, look at this one is enough!
Nov 22,2023
At present, there are a wide variety of ceramic tile adhesives on the market, and the industry words used by the shopping guide also make consumers confused. In addition, new species of rock plates emerge in endlessly, resulting in consumers not knowing which is good and which is suitable. In fact, according to the selection requirements and principles of tile glue, just remember one thing: the lower the water absorption rate of brick material and the larger the size, the better the tile glue with adhesive force should be selected.
Next, Brother Wen will explain in detail the following knowledge points that we often encounter. If it is helpful to you, please share the collection!
01
Detailed explanation of the grade of tile glue
[What do you mean by classification C, D and R of tile glue?]
The C, D and R classifications of ceramic tile adhesives refer to the codes of the three types of ceramic tile adhesives. Under the standard of JC/T 547-2017 "Ceramic Tile Adhesives", the corresponding types are cement-based adhesives, paste emulsion-based adhesives and reactive resin adhesives.
T of tile glue refers to anti-slip, F is fast setting, S1 is flexible, S2 is high flexibility, and E is extended drying time.
02
Definition and performance classification of cement-based tile adhesive
According to JC/T 547-2017 "ceramic tile adhesive" standard, ceramic adhesive according to the basic performance, additional performance and special performance can be combined into different types of products, details are as follows:
Among them, the performance number 1 represents the ordinary type, the number 2 represents the enhancement, and different performance has clear technical index requirements, the details are as follows:
03
The difference between the two common standards of tile glue
▲ C1 JC/T 547-2017 Ceramic Tile Adhesive
▲ I-II Type GB/T 25181-2019 Ready-mixed Mortar
In practical application, matching products should be selected according to the specific use environment and brick type, and at the same time, the third-party testing unit should also be tested according to the specific implementation standards of the product.

Introduction to the naming rules of tile glue
The first part uses letters to indicate the type of product, and C is a cement-based adhesive.
The second part uses numbers to indicate the performance of the product (basic performance or additional performance),1 is an ordinary adhesive, and 2 is an enhanced adhesive with additional performance.
The third part uses letters to indicate different special properties, fast-setting adhesive with F, anti-slip adhesive with T, extended open-air time adhesive with E, and cement-based adhesive with special deformation properties with S (among which, flexible adhesive with S1, high flexible adhesive with S2).
For example, C1 ET is a cement-based adhesive that resists sliding and prolongs the drying time, which represents that the product has a stable and TDW-I high-energy tile adhesive (no need to dip the brick with strong adhesion).

Tile glue selection recommend scheme
The product model is stably recommend.
TDW-I super tile adhesive
★Strong adhesion★Wall and floor tiles are applicable★No dipping brick required★Low shrinkage
The product model is stably recommend.
TDW-II super tile adhesive
★Strong adhesion★Wall and floor tiles are applicable★No dipping brick required★Low shrinkage
The product model is stably recommend.
TDW-III large plate tile adhesive
★super anti-slip★High flexibility★Extra long airing★Strong adhesion
The product model is stably recommend.
TDW-IV rock tile adhesive
★super anti-slip★High flexibility★Extra long airing★Strong adhesion
When the base is a flexible base, it is necessary to use flexible adhesives, such as gypsum board base, fiber cement board base, insulation base, etc. Regardless of the water absorption rate of ceramic tiles, flexible adhesives must be used. Therefore, the selection should be C2S1E, C2S1ET, C2S2ET and other flexible tile adhesives
Generally speaking, the main use areas and uses of tile glue can be clearly seen through the packaging instructions of the product, and it can be seen at a glance as long as the packaging is clearly seen before purchasing.
