Abstract
Described herein are surface coverings comprising: a linoleum core; a top major surface having a first length and a first width, the top major surface terminating at a first edge; a bottom major surface having a second length and a second width, the bottom major surface terminating at a second edge; and a peripheral edge surface extending between the first and second edges, the peripheral edge surface being planar and oriented obliquely to the top and bottom major surfaces; wherein at least one of the first length or first width is smaller than the second length or second width respectively. Methods of making and using these surface coverings are also described.

A surface covering comprising:
- a linoleum core;
- a top major surface having a first length and a first width, the top major surface terminating at a first edge;
- a bottom major surface having a second length and a second width, the bottom major surface terminating at a second edge;
- and
- a peripheral edge surface extending between the first and second edges, the peripheral edge surface being planar and oriented obliquely to the top and bottom major surfaces;
- wherein at least one of the first length or first width is smaller than the second length or second width respectively.
A floor covering system comprising:
- a plurality of floor tiles arranged edge-to-edge on a support base, each tile comprising:
- a linoleum core comprising a first linoleum layer and a second linoleum layer;
- a top major surface terminating at a top edge;
- a bottom major surface terminating at a bottom edge;
- and
- a peripheral edge surface extending between the top and bottom edges;
- and
- a carrier embedded at least partially in the first linoleum layer;
- wherein the peripheral edge surface is planar and oriented obliquely to the top and bottom major surfaces;
- a gap formed between adjacent tiles between the peripheral edge surfaces of the tiles, the gap having a greater width between the top edges of adjacent tiles than at the bottom edges.
A floor tile comprising:
- a linoleum core comprising a first linoleum layer and a second linoleum layer;
- a carrier embedded at least partially in the first linoleum layer;
- a polymeric wear layer disposed on the second linoleum layer;
- a top major surface terminating at a plurality of top edges, a bottom major surface terminating at a plurality of bottom edges, and a plurality of peripheral edge surfaces extending between the top and bottom edges around a perimeter of the tile;
- the top major surface being arranged parallel to the bottom major surface;
- the wear layer defining the top major surface;
- the first linoleum layer defining the bottom major surface;
- wherein the top major surface has a first area and the bottom major surface has a second area, the second area being larger than the first area.
