Stencils and Borders on Concrete Want a one-of-a-kind entrance way, pool patio or business floor? Stencils offer unlimited customization when refinishing concrete flooring, countertops or vertical surfaces. From a distinctive monogram to a geometrical design, your imagination is the limit. The best idea is to finish your stencil with a decorative border and cover the whole area with an epoxy coating to protect the design and make it shine.
