Abstract: A method of covering a surface with a matrix-forming polymer includes the step of applying a vinyl acrylic latex polymer to soil such that the polymer bonds particles of the soil to form a substantially continuous latex phase. A method of covering an earthen surface includes: preparing a soil layer; spraying a vinyl acrylic latex polymer on the soil layer such that the polymer bonds particles of the soil in a substantially continuous latex phase; and compacting the sprayed soil. A device for preparing soil for the application of a polymer to form a hardened surface includes rotatable tines and a distribution wand positioned proximate the tines. A mobile delivery system for dispensing a polymeric composition which when applied to soil creates a hardened surface includes containers having a polymer and a migrating agent stored respectively therein and a plurality of other associated trailer-mounted devices.
