Rigid polymeric modular flooring plank, method of making same, and method of using same

A flooring system comprising at least a first rigid polymeric modular flooring plank and a second rigid polymeric modular flooring plank of the same size and shape as the first rigid polymeric modular flooring plank, said first rigid polymeric modular flooring plank and said second rigid polymer flooring plank are each one continuous piece having a top surface, a bottom surface and multiple sides defining the edges of said rigid polymeric modular flooring plank, each of the edges being absent of a mechanical locking design, and the rigid polymeric modular flooring plank includes the appearance of one tile or multiple tiles as part of said top surface with each of said one tile or multiple tiles having multiple edges and a decorative surface and each of said one or multiple tiles completely surrounded by simulated grout lines that have a depth and either have a full width W or a half width ½W, wherein any simulated grout line that is located at any of said one or multiple sides has said half width and all other simulated grout lines have said full width, wherein said first and second rigid polymeric modular flooring plank comprises a polymeric base layer, a decorative layer and at least one wear layer located above said decorative layer, wherein said simulated grout lines are formed by removing portions of at least said wear layer and decorative layer, and

• wherein the first rigid polymeric modular flooring plank and the second rigid polymeric modular flooring plank are arranged adjacent to one another, such that one or more of the free edges of the first rigid polymeric modular flooring plank and one or more of free edges of the second rigid polymeric modular flooring plank form a simulated grout line having the depth and full width W of the simulated grout lines having said full width W, and a filler material is present in said simulated grout line so as to fill said simulated grout line.
