water-based epoxy grout. It is an aqueous based epoxy grout comprising: at least one epoxy resin; at least one polyamine compound; at least one mineral filler; and at least one nonionic surfactant having at least one polyoxyethylene chain. The presence of at least one nonionic surfactant having at least one polyoxyethylene chain allows to increase the grout affinity for water, and thereby make the grout sponge cleaning process after its application much easier to ensure removing excess grout while maintaining a continuous defect-free finish without causing air holes to form inside the joints.
