Here is the formula of tile adhesive, let’s discuss it.

The formula is okay. Adding more than 3 kg of 200,000 viscosity cellulose ether will be sticky if it is a thick coating method. It is recommended to add 2-2.5kg. Adding 0.5kg of starch ether appropriately can increase the slip resistance. Whether adding calcium formate is depend.
Reduce the cement to 350, the coarse sand to 100, and the cellulose ether to 100,000. The dosage of 2.2 kg is enough. The amount of Redispersible Polymer powder depends on the positioning of the tile adhesive. C1 must be at least 15 kg. Starch ether 0.3-0.5 is enough. The anti-slip and calcium formate should be fine-tuned according to construction and climate conditions.
Calcium formate is initially used during low-temperature construction as an early strength agent. Its addition can improve the early strength. Since cement hydrates too slowly at low temperatures, it is used to accelerate the cement hydration reaction. Among ceramic tile adhesives, they are primarily used in the north cold area, where the temperature is low, while in the south part, the temperature is high most of the time, so it is simplified. Why is it recommended to add some calcium formate when making vitrified brick? Because the water conductivity could be better, the amount of water added to the tile adhesive far exceeds the amount required for the cement hydration reaction. Adding some calcium formate can improve the 12-hour or 24-hour strength to meet later construction needs.
