Epoxy resin is a two-part adhesive used at the manufacturing level to fill the micro-fissures of a stone material, repair small cracks and enhance the overall look of a particular granite. Such a “system†usually is a bi-component adhesive, clear in color and with a very low viscosity. The epoxy is poured on the whole surface of the slab, left to cure, and then removed from the surface using the standard abrasives normally used for polishing granite.
To understand what causes the color enhancing of the granite, we need to digress a little bit and see what, in reality, give us the perception of color in our everyday life. The world as we see it, is not colored per se.
