A surface covering comprising:
- a carrier;
- a first linoleum composition adjacent to the carrier comprising:
- linoleum cement;
- a first organic filler;
- and
- a first inorganic filler;
- and
- a second linoleum composition comprising:
- linoleum cement;
- a second organic filler;
- and
- a second inorganic filler;
- wherein the ratio of linoleum cement to the second inorganic filler in the second linoleum composition is from about 1.75:1 to about 3.5:1, and wherein the weight ratio of organic filler in the second linoleum composition to organic filler in the first linoleum composition is greater than 1.5:1.
