What does the marking on tile adhesive mean: D2TE, C1T, C1TE, C2TE, C2TE S1

Modern adhesive compositions for laying tiles and other materials have different applications, differ in physical properties, as well as the rate of solidification. Each composition has a special marking on the package indicating the properties and scope of application, which can be difficult for inexperienced craftsmen to understand. We have prepared for you a simple hint for marking tile glue. 

• D2TE is a high—strength, thixotropic adhesive with increased viscosity and increased time of the open layer. It is suitable for facing vertical surfaces, because it has a high resistance to vertical sliding. This variety includes paste-like glue Teknofay 200 D2TE (Teknofey 200 D2TE). 
• C1T is a standard cement—based tile adhesive with increased viscosity. It has high adhesion and is suitable for most interior work, for example, facing horizontal and vertical bases in residential premises, hospitals, shopping malls. Resistant to vertical slipping. An example of a product is Teknofay C1T (Teknofay C1T). 
• C1TE is a standard adhesive with increased viscosity and extended open layer time. It has a high adhesion ≥ 0.5 N/mm2, suitable for laying materials on concrete, plaster, screed, as well as ceramics on ceramics. This category includes Teknofay Plus C1TE (Teknofay Plus C1TE).
• C2TE is an improved adhesive composition with high adhesion, increased open layer time and increased viscosity. Does not slide off vertical bases, suitable for laying large slabs with a size of 60x60. An example of a good tile adhesive of this marking is Teknofay EX C2TE (Teknofey EX C2TE). 
• C2TE S1 is the same C2TE, but with increased elasticity. The main scope of application is the laying of ceramics, porcelain and granite inside and outside the premises. It is optimally suited for facing surfaces that are subjected to temperature deformation, for example in baths, thermal springs, heated pools. It is also applicable in the arrangement of underfloor heating. An example of the product is an elastic adhesive for ceramic tiles and granite Teknofay Flex C2TE S1 (Teknofay Flex C2TE S1). 

Now, looking at the packaging of tile adhesive, you will be able to figure out what exactly the product is intended for and choose the best option for any cladding.
