When an epoxy resin is mixed before application, it contains a hardener that contributes to the curing process. This is when you have the opportunity to add a specific color or finish to your epoxy that will reflect your personal style. One of the greatest features of an epoxy overlay is the endless options for customization. Choose from a variety of colors, shades, hues, swirls, sparkles, metallics, and more that allow you to perfectly match your decor and preference.
