GFRC Backer Mix Kit

GFRC Backer Mix Reinforcement – XS Backer Bag Mix

SureCrete’s XS GFRC Backer Mix is a dual component cement based bag mix that is unmatched in fiber loading. It is not a “stand alone” mix, but is designed to be used in conjunction with XS Face or XS Precast. XS Backer greatly reduces the materials and labor required to construct traditional precast concrete. Reinforcement steel is eliminated, thinner precast pieces are routine, quicker production times are accomplished, and no “B” mold is required. A stronger, denser and more flexible cement-based composite is created by combining cutting-edge technology with modern fiber advancements. With a wide range of coloring and texture selections along with the manipulation of water demand and placement, design considerations are nearly limitless. XS Backer when used in conjunction with XS Face or XS Precast produces concrete countertops, fireplace mantles and facades, shower surrounds, wall panels, furniture and many other architectural elements. XS Backer is the perfect medium for residential, commercial, and industrial applications.
Backer Mix is a high fiber early strength, dual component bag mix ideal for precast concrete and architectural concrete applications that require longer, thinner, more flexible and lighter pieces that cannot be accomplished through traditional poured application. Ideal for adding strength to concrete countertops, fireplace pieces, architectural panels, precast rocks and thousands of other custom precast items.
