1.Question:How do you remove it if the mortar sets up?
Answer:Before the cement or tile glue has completely dried up (usually no more than 6 hours), tighten the adjusting cover in the opposite direction, then rotate the T-pin 90 degrees so that the T-pin turns to a zigzag parallel to the tile, and remove the leveler.
2.Question:How are you supposed to remove these before 6 hrs, if you can't walk on the tile for 12 to 24 hours after laying it?
Answer:A skilled decorator should know that the general tile can be stepped in the middle after 6 hours, but be careful to step on it. thank you very much.
3.Question:what thickness tile do these work on?
Answer:You can use these levelers in a max thickness of tile is 1/2 in. This will give you enough room to drop the tee below the tile and tighten. It will not work on anything thicker than 1/2 inch.
