What is the easiest method of getting a straight line on a floor?
Find the center of the floor or the point at which your tiles will intersect out in the middle of the room. Now snap a chalkline across the room. Now square off that line and snap the 90 degree line also. Purchase a piece of 20 gauge metal stud track 10′ long. Screw this track down right on the longest of the 2 chalklines on the floor. Lay your tile (except for the one tile right where the chalklines intersect). Lay one row all along and butted up tight to this metal stud track.Let tiles set until they grab good. Remove track and install on the other chalkline. Lay 1 row of tiles up against metal track-let dry. Now fill in the remaining tiles using spacers to keep grout lines straight. I know you don’t like just the chalklines, however if you just hold your thinset back off the chalkline 1/8″ or so, you can still see the line and get good layer of thinset down. My tile sub uses a PLS laser that puts down 2 intersecting laser lines at 90 degrees. It’s slick.
