Determine the Tile Measurement for the Outside Edge
Terrazzo is composed of marble chips and/or dust with a cement binder. It is available as finished individual tiles or as poured in place over a concrete slab, and then ground to the polished finish. When using tiles, many contractors try to replicate the look of the slab terrazzo by butting the tiles up against one another.
After taking measurements, dry fit the first row of full tile from the chalk line to the outside wall; lay out and mark the last row of tiles that will need to be cut to fit. To determine the tile cuts, you can use a technique called "jump scribing," which is simply to overlay the second tile from the wall and scribe a line down the first tile for the cut as shown in the image.
