A metallic epoxy floor coating is quite simply a low yellowing epoxy, with a metallic pigment mixed within. In other words, tiny, almost glitter-like pigments are mixed into an epoxy resin and then poured onto the floor or substrate. When these pigments become agitated with a paintbrush or roller, they gather, separate, twist and turn to reflect light at different angles. Eventually, the epoxy hardens and the metallic pigments are locked into place and give a three dimensional, swirly look. The installation technique is what determines the final look of the floor and is a critical part in attaining the desired look.
