Ceramic tile sealant is powdered and powdered after seam construction, which is mainly caused by two aspects. First, in the early deployment of ceramic tile sealant paste, excessive water was added, and the composition of ceramic tile sealant binder was diluted by water, which could not form a compact and effective structure, and then appeared powder and powder. Another aspect is the construction of ceramic tile sealant filler, because water retention is a challenge, ceramic tile sealant lacks water hydration hardening reaction, the degree of hydration hardening will be limited, so the hardness and strength of the material will be affected, easy to appear material powder, powder problems.
Before the ceramic tile filling construction, the most important thing is that when the tile filling agent slurry is deployed, too much water is added, that is to say, when the material is too sparse, uncovering or mixing materials, no electric mixer is used to keep the material uncovered, or the remaining ceramic tile filling agent slurry is dry before and after construction, and water mixing is added for reuse. These three methods will lead to the problems of pink and poor strength of ceramic tile filler.
In addition, the ceramic tile sealant is actually the ability to store, retain, moisturize and lock water after the construction of the seam. When the brick seam is too small and the ceramic tile filling agent fills the seam, the width of the material is very small, that is, the volume of the material is small. Small size is not conducive to the water retention of sealing materials, easy to be absorbed by ceramic tiles in the air moisture, leading to the problem of ceramic tile sealant powder; in addition, ceramic tile sealant fills the gap, if the filler is not full, compact, loose, the gap between ceramic tile sealants is easy to lose moisture. This will lead to the lack of water in the hardening process of ceramic tile filling seam slurry, which is easy to appear powdery and hardness is not enough; if the weather is too dry and hot, the construction of ceramic tile sealant is easy to absorb air moisture, resulting in lack of water quenching conditions, there will be powder, hardness is not enough, so when the weather is hot or dry, spray water maintenance, appropriate moistening. An important reason for wet materials.
In order to prevent the powder change of ceramic tile sealant and pink, in the early stage of distributing ceramic tile sealant slurry, the amount of water should be appropriate and not too much. When the later stage of building protection after ceramic tile sealant, the water should not be less, and the material should be filled with water.
