Abstract

A composition for use as a floor coating, the composition including an at least one polymer having a solids content, based on a total weight of the composition, an at least one resin having a solids content, based on a total weight of the composition, and an at least one plasticizer having a solids content, based a total weight of the composition. Further, the solids content of the at least one plasticizer to the solids content of the at least one polymer is between about 20% and about 25%, the solids content of the at least one polymer and the solids content of the at least one resin are in a ratio of about 25:1 to about 35:1, and the composition has a percent elongation of at least 100% and a tensile strength of at least 1000 psi, when applied to a surface.
