Abstract
Described herein are surface coverings comprising a carrier, a first linoleum composition, and a second linoleum composition; wherein the flow rate of the first linoleum composition is greater than the flow rate of the second linoleum composition.
Claims20
A surface covering comprising:
- a carrier comprising an intersecting grid of first strands and second strands;
- a first linoleum composition having a first flow rate (Vmax) that ranges from about 300 cmm/s to about 1000 cmm/s, the first linoleum composition comprising:
- linoleum cement;
- a first organic filler;
- and
- a first inorganic filler;
- and
- a second linoleum composition having a second flow rate (Vmax) that is less than 200 cmm/s, the second linoleum composition adjacent to the first linoleum composition and comprising:
- linoleum cement;
- a second organic filler;
- and
- a second inorganic filler;
- and
- wherein the ratio of the first linoleum composition flow rate (Vmax) to the second linoleum composition flow rate (Vmax) ranges from about 5:1 to about 20:1.

A surface covering comprising:
- a carrier comprising an intersecting grid of first strands and second strands comprising from about 20 voids/cm2 to about 30 voids/cm2;
- a first linoleum composition having a first flow rate (Vmax), the first linoleum composition adjacent to the carrier and comprising:
- linoleum cement;
- a first organic filler;
- and
- a first inorganic filler in an amount ranging from about 25 wt. % to 35 wt. % based on the total weight of the first linoleum composition;
- and
- a second linoleum composition having a second flow rate (Vmax) comprising:
- linoleum cement;
- a second organic filler;
- a second inorganic filler;
- and
- wherein the first inorganic filler comprises particles having an average particle size of from about 0.5 μm to about 20 μm.
