What to pay attention to when pasting large-scale vitrified tiles

Question 1 In general, what are the characteristics of large-scale vitrified tiles? How to choose tile adhesive reasonably to ensure the safety of pasting?
Answer: 1) The size is large, generally the width of a single piece exceeds 600×600mm, and the thickness of the brick is usually relatively thick, especially the one that has been polished. It is difficult to adjust the thickness of the adhesive layer and the effective bonding area when pasting. It requires a good flatness of the base surface, smooth scraping of the adhesive, good wettability, and a long waiting time and opening time in the barrel. .
2) The water absorption rate is low, and the water absorption rate of vitrified tiles is generally not more than 0.5%, which belongs to full ceramic tiles. The better the degree of vitrification, the lower the water absorption, and the better the physical and chemical properties of the product. This requires the adhesive to have high strength, especially the bonding strength with dense materials.
3) The weight is relatively large, and the unit weight of vitrified bricks is nearly 30kg/㎡. The adhesive is required to have better anti-slip performance and stronger initial bonding force.
4) The potential deformation stress is large, especially under the influence of temperature difference shrinkage stress, it is easy to delaminate with the adhesive. The adhesive needs to have high bonding strength, flexibility, and can adapt to the deformation of the facing layer without falling off.
Recommended product model – C2TS1E.
Question 2 What kind of adhesive should be selected when pasting large-scale vitrified tiles?
Answer: When pasting vitrified tiles, it is necessary to choose C2 level tile adhesive. Because the density of vitrified tiles is very high and the water absorption is very small, the bonding strength of C1 grade tile adhesive is only 0.5MPa, so it is difficult to guarantee the firm adhesion of vitrified tiles.
Question 3 When installing vitrified tiles, what are the requirements for the base layer?
Answer: The base surface should be solid and flat; if there is loose matter (dust, etc.) on the base surface, it should be cleaned; if there is clear water, it should be blotted until there is no clear water; It is necessary to ensure that the base layer meets the construction conditions before laying tiles.
Question 4 Large-scale vitrified tiles use professional tile adhesives. Once a mistake is made, it is very difficult to remove when it needs to be adjusted. What should I do?
Answer: When professional tile adhesives paste large tiles, there will be such problems. Professional tile adhesives have adjustable properties, which can adjust the position of the tiles by moving them up and down or left and right. If it is necessary to peel off the tiles and paste them again, we suggest that before pulling out the tiles, use a string to separate the tile adhesive from the middle, separate the tile adhesive layer and then pull out the tiles
