text: Roger: When you're laying tile how many rows can/should you do in a day?
  Jim: Floor?
  Roger: walls
  Dan: which mortar are you using?
  Roger: pre-mixed. seems like it dries very slowly
  Jim: Why would it matter how long it takes to dry? Only takes a day to be able to grout with the pre mix. You can do as many rows as you like also.
  Roger: Right o. I just didn't know if they would shift around with more rows stacked on them?
  Dan: <file_photo> you just make a level ledger (2nd row). Mark a center line on all walls then see where the last tile is going to be on sides and ceilings. You do the bottom row closest to the shower pan last after the ledger row dries.
  Jim: Exactly, don't do the bottom row 1st, for some reason makes getting everything to line up pretty difficult. And push everything flat on the tile with a level so it looks good.
  Roger: Okay, good to know. I was just going to start at the bottom and work my way up
  Dan: Might not work. Shower pans are usually not level so everything will end up off.
  Jim: Do you have a digital level? I can give you mine if you need
  Roger: I have a digital one.
  Jim: Ok cool.
  Dan: Good luck. Let us know if you need anything.
target: Roger can do as many rows of tile in a day as he wants. He should make a level ledger, mark a center line and do the bottom row when the ledger row dries.
