It depends on the nature of the base course, the parameters of the base material and the use area. This is the principle of choosing tile adhesive
On the nature of the base course
When it comes to base course, concrete or brick masonry are common. In the selection of ceramic tile adhesive, it is necessary to understand the material of facing material, and to understand the characteristics of the base course.
The base can be roughly divided into rigid base and flexible base. Concrete, brick masonry, masonry mortar and cement mortar belong to rigid base, while cement fiber board, gypsum board, plywood and external insulation system of external wall belong to flexible base.
Rigid base in the choice of ceramic tile adhesive, more will be based on the performance of the main material and the use of parts to choose tile adhesive; and flexible base use of ceramic tile adhesive is generally required to have a certain flexibility, otherwise later due to the deformation of the base and cause hollowing off problem.
On the parameters of the base material
When choosing tile adhesive, special attention should be paid to the water absorption and size of ceramic tile. The lower the water absorption of ceramic tile, it means that the more dense the ceramic tile is, the better the suction cup is required to be selected, that is, the ceramic tile adhesive with high level.
The bigger the size of ceramic tile is, the greater the load is, the higher the requirement of adhesive force of ceramic tile is put forward.
In case of some special substrates, the efflorescence and color permeating should be considered. For example, light colored natural stone has more micropores, and the ceramic tile adhesive is usually cement gray. When such gray ceramic tile adhesive is used to paste natural stone, it is easy to seep color and reduce the color of stone.
In order to avoid this situation, it is recommended to choose white tile adhesive as the tiling material.
On the use area
Different use scenarios, tile areas, matching tile adhesive in the performance requirements are different.
For example, the threshold stone area at the junction of kitchen and bathroom, hall and room, that is, the transition place of dry and wet areas, this part of the requirements for tile adhesive, in addition to adhesive force, it is best to have waterproof and impermeable function.
In this way, the water vapor can be prevented from running into the living room and the room, so as to avoid the influence of water vapor invasion on the floor and wall coating.
Like toilet this kind of long-term immersion environment, tile adhesive had better have certain impermeability. Therefore, in order to improve the impermeability of ordinary ceramic tile adhesive, the ceramic tile adhesive partner can be added into the ceramic tile adhesive, so that the durability of the ceramic tile adhesive is more guaranteed.
For such parts as flue, light partition wall, they have a common feature is often vibration or unstable base, so choose flexible tile adhesive. In this way, the deformation and vibration of the sub base wall can be buffered by flexible tiling materials to ensure that the tiles can be firmly pasted on the wall.
