    GFRC Backer Mix for Reinforcement for Casting Concrete - XS-Backer by SureCrete

    GFRC Backer Mix for Reinforcement for Casting Concrete – XS-Backer by SureCrete


    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 blend but is designed to be used in conjunction with XS Face or XS Precast. XS Backer significantly 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 cementitious composite is created by combining cutting-edge technology with modern fiber advancements. With a broad 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.

    XS Backer was designed to help alleviate the typical constraints of precast concrete – thick and heavy pieces that can’t span long distances without some structural reinforcement such as steel rebar. Using the “reduction method” we’ve detailed in our in-person training class events throughout the country and in our instructional how-to videos, we’ve enabled you – the contractor or homeowner looking to craft a new architectural or precast concrete piece – to make casted concrete at a fraction of the typical thickness and weight of normal concrete as well as allow you to create much longer and wider pieces, all without the use of additional structural support.

    Information About CHENG D-FRC Backer:
    In addition to XS Backer, which is made available in a white Portland cement formula and can be colored accordingly, SureCrete has partnered with CHENG and The Concrete Exchange to make a vibrant grey-portland formula available in the form of the CHENG D-FRC Backing Mix. DFRC Backing Mix is an excellent; fiber-reinforced concrete formulated to allow saturated colors in a convenient dual-component package. The CHENG D-FRC (Decorative Fiber Reinforced Concrete) System is engineered for precast concrete professionals who demand time and labor savings combined with maximum design flexibility including large format capacity. CHENG D-FRC BackingBlend is a formulation of Portland cement, engineered fibers, and sand. The excellent blend consistency and exceptional workability deliver amazing structural reinforcing to any CHENG D-FRC SprayBlend applications.

    How Do You Apply SureCrete XS Backer Glass Fiver Reinforced Concrete backing material?

    GTRC Backer Mix can do every casted concrete project you work on stronger and lighter:

    1. XS Backer is not a stand-alone casting material and is meant to be applied to a mold AFTER the application of a thin layer of XS Precast, XS Face or XS Terrazzo mix.
    2. In a 5-gallon bucket, pour in XS Modifier and any powder colorants you want to use to integrally color your mix, and mix thoroughly, slowly adding the XS Backer dry contents from the bag.
    3. Depending on the thickness, you may pour XS Backer into the mold, or just place it into the mold directly by hand in the areas you wish to strengthen.
    4. While wearing gloves, use your hands to push material around inside the mold to reach the overall shape and thickness you are looking to add.
    5. In warm weather, allow 4-6 hours before removing from the mold (in freezing temperatures or for a very thick pour, allow to set overnight).
    6. Once de-molded, treat the piece the same as you would any surface cast using our XS Precast, XS Terrazzo or XS Face mix designs.

    Frequently Asked Questions About XS GFRC Backer Mix for Casting:

    Question: How long do I have to leave XS GFRC Concrete Backer Mix Casting Mix in the mold?

    Answer: You don’t need to leave a piece in the mold any longer if you’ve added XS GFRC Concrete Backer Mix, in most climates, 4-6 hours is sufficient. In much colder temperatures, extend that time to 8-12 hours, but don’t leave it in the mold any more than 24 hours.

    Question: Can I use XS GFRC Concrete Backer Mix in a Pour-In-Place project?

    Answer: As it is NOT a finished product, we would not suggest using this as your sole finished surface, however, if you wanted to place the backing material in FIRST, and then apply a top, or finish coat after, that would be an acceptable use of this product.

    Question: Can I grind and polish XS GFRC Concrete Backer Mix?

    Answer: XS GFRC Concrete Backer Mix was not meant to be a stand-alone product, and small hairs and fibers will be exposed if the product is ground or polished.

    Question: Can I use XS GFRC Concrete Backer Mix outside? Will the pieces I make freeze and break?

    Answer: The addition of XS GFRC Concrete Backer Mix makes our already strong Xtreme Series products even MORE resistant to freeze-thaw climates as it adds the amount of strength to deal with the rapid temperature changes.
