    Abstract: An epoxy grout system comprises a first epoxy resin component comprising a novolac epoxy resin, a bisphenol F epoxy resin, and a non-reactive diluent, and a second epoxy curing agent component comprising an amidoamine. The epoxy grout system has excellent chemical resistance while maintaining good installation properties. Another epoxy grout system comprises a first epoxy resin component which is resistant to a mixture of oleic acid and water, a second epoxy resin component which is less resistant to a mixture of oleic acid and water than the first component, and a third amine-containing curing agent component operable to cure both the first and second epoxy resin components. Optionally, the curing agent component can be provided as a plurality of amine-containing curing agent components of respective colors, whereby a user can select a curing agent component of a desired color for use with either the first or second epoxy resin component.
