The present disclosure describes a unique, two-part, water-soluble polymer matrix material and a method of application that immobilizes a wide variety of loose powder or crystalline hazardous materials and renders them safe or at least safer for handling and transport. The polymer matrix material is a two-part polymer material comprising a liquid cross-linking polymer and a cross-linking agent, initiator, or biocide contained in a solution. The cross-linking agent functions to cross-link the polymer and cause it to harden in place.
