The CR-10S4 now has a Creality coated (carborundum glass) build plate like the smaller printers, which isn't supposed to require any glue, but it still suffers from some adhesion issues with larger prints (prints warping or pulling off the bed). It's recommended to print with a raft to minimize this, and perhaps also to heat the bed a bit more than the smaller printers to make up for the large bed size.
