What are the best practices for applying thin set mortar for tile installation?

The best practices for applying thin-set mortar for tile installation include properly mixing the mortar to the right consistency, spreading it evenly on the substrate using a notched trowel, pressing the tiles firmly into the mortar, and ensuring proper spacing between tiles. It is important to work in small sections at a time to prevent the mortar from drying out before placing the tiles. Finally, use spacers to maintain consistent grout lines and allow the mortar to cure for the recommended time before grouting.
