Xcel Surfaces Stamp Overlay is a polymer modified, cementitious surfacing system designed for use on structurally sound concrete substrates. The Stamp Overlay System is used for interior or exterior applications and can be stamped to simulate a variety of textures and patterns ranging from natural stone to wood. Xcel Surfaces Stamp Overlay System can also be pigmented or stained to produce an extremely attractive, durable, stain resistant surfacing system for concrete. When properly mixed and applied, Xcel Surfaces Stamp Overlay will not shrink when setting, resists breakdown due to dampness and cures to an extremely durable surface that will not crack or break up. A typical finished application is 1/4 Inch to 3/8 Inch (.635 cm- .95cm) maximum thickness.
