(pronounced FLOHT strihp)
When setting tile or stone in beds of mortar, it is common for installers to use strips of material that help them level the hard surfacing material to the desired angle. If on a countertop or vertical surface, chances are that you want the tile installed perfectly flat. If on the floor where drainage is an issue, you want a slight angle, coaxing any water towards a drain. Float strips simply act as guides, making the installation process easier.
