Methods and apparatus for laying marble tile flooring utilizes a form and method for using the form. The form provides for applying layers of a sealant, mud and thin set to a height determined by the form for laying the first tile in a horizontally level position. Second and subsequent tiles are laid relative to the first laid tile by gauging off the first laid tile and fixing the height of sealant, mud, and thin set such that the second and subsequently laid tiles are level with the first tile and parallel to the edges of the first laid tile. The result is a completely horizontal tiled floor with each tile level to an adjacent tile and parallel and or perpendicular relative to each other tile.
