When using rapid-setting tile adhesive outdoors, attention should be paid to the following:

1.Control of Mixing Quantity: Due to the shorter pot life and open time of rapid-setting tile adhesive, the mixing quantity should not be excessive to prevent premature solidification.

2.Control of Application Area: Avoid applying adhesive over a large area at once. Complete the application within the usable time of the product to ensure the adhesive remains active.

3.No Re-adding Water: Under no circumstances should adhesive that has lost workability or is nearing setting be re-mixed with water for further use. This can significantly impact both the early and long-term bond strength and may cause severe whitening.

4.Use Immediately After Mixing: Use the adhesive immediately after mixing to prevent premature drying. If rapid drying occurs, reduce the mixing quantity, lower the mixing water temperature, or decrease the mixing rate appropriately to extend the working time.

In summary, controlling the mixing quantity and application area, refraining from re-adding water, and using the adhesive immediately after mixing are crucial considerations when using rapid-setting tile adhesive outdoors to ensure proper construction and bonding quality.
