    Urethane Concrete Crack Treatment Fast Drying – SCT-22 by SureCrete


    Concrete Crack Treatment Fast Drying Urethane SCT-22 by SureCrete

    Concrete Crack Treatment Fast Drying Urethane SCT-22 by SureCrete


    Surecrete’s SCT-22 concrete crack treatment is a rapid set, technologically advanced, high strength, ultra-low viscosity urethane treatment material. This 2-part, 1:1 system is 100% solids, no VOC’s and designed for rebuilding spalls and treating static cracks in concrete very quickly. SCT-22 may be used before the application of an overlay for concrete that has random cracking or as a stand-alone treatment for hairline cracks and damaged concrete. Its rapid setting times makes SCT-22 the premier restoration product for industrial warehouse floors that have traffic area spalls and construction and a sign of joint damage. A ten to fifteen minute period is all that is required for “drive-over” time. SCT-22 cures from –20°F (-29°C) to 130°F (54°C). It is self-leveling, self-priming, and meets USDA and FDA requirements.

    Whatever your project may be, the priority of surface preparation is to make sure that your surface is sound enough for whatever decorative coating or overlay you wish to apply. SCT-22 will help repair concrete cracks and keep your project on time and budget. Repairing or treating a break will always be more cost efficient than completely destroying a concrete slab and pouring a fresh one. It’s simple application method also allows it to be used by more than just trained professional contractors. Homeowners and DIY weekend warriors can use SCT-22 that seals concrete without any formal training to repair their aging and cracking cement slabs.


    Places to Use SCT-22 a Concrete Crack Treatment:

    • driveways, sidewalks, and steps
    • apartment/condominium walkways
    • patios & pool decks
    • interior commercial and residential flooring
    • repairing floor cracks
    • Concrete Step Stress Cracks
    • old concrete slabs
    • worn-down surfaces
    • cracked concrete surfaces
    • injected into hairline cracks
    • repairing cracks concrete may have
    • cracked walls

    How Do You Apply Surecrete SCT-22 Concrete Crack Treatment?

    SCT-22 was meant to be used by anyone, not just professional contractors with formal training, see repair step by step:

    1. Use an electric grinder and a diamond “turbo blade” to open up the crack and remove any structurally unsound water or loose concrete debris.
    2. Clean out the newly “squared” cracks using compressed air to remove all dust and particulates.
    3. Fill the dressed crack with clean, dry sand until flush with the surface.
    4. Shake cartridge for at least 30 seconds, then remove the cap and install the flow restrictor on top of ports and insert the assembled dual cartridge into the “gun.”
    5. Point tip up and gently squeezing the gun’s trigger to bleed off air in the cartridge, then squeeze off a small amount of material to make sure only properly mixed material is applied.
    6. You’re finally ready to apply SCT-22 to the crack! Just make sure to apply even pressure while dispensing the product for fixing concrete continuously.

    Frequently Asked Questions About Concrete Crack Treatment:

    Can I use a different gun than one it comes with?

    Technically yes, but it would have to be of the same type that allows for two cartridges and combines them at the tip in the same manner as the gun that is provided.

    If I use SCT-22 to fix a crack, can I be sure the crack won’t come back?

    Unfortunately no, Concrete moves throughout its life, it expands and contracts with temperature change, humidity levels, and because of the substrate, it is poured on. It is called a treatment because it fills the voids for an overlay to be applied so that the crack won’t transfer to the overlay. This said, it still could come back either in the same spot or near where it was on concrete floors.

    Will sealer stick to the SCT -22

    Yes, Most Dura-Kote sealers will stick to SCT-22 as long as it is sanded or roughed before it is applied. Sealers require a certain amount of “tooth” to allow for a proper bond. This is sufficient for Sct-22.

    Do I have to use the whole container or can I save some for another job?

    If you save the plug that comes with shipping, you can re-insert it and save for another job. You will have to get a replacement mixing tube and cartridge dispenser to reuse. Which are available at Surecrete.

    How soon can I go over SCT-22 with a new coating?

    In as little as 15-20 minutes, SCT-22 is ready to be ground out to make a level surface and is ready at that point for a new coating to be applied.

  • Questions and Answers about SCT-22 Concrete Crack Treatment

    Can I use a different gun than one it comes with?

    Technically yes, but it would have to be of the same type that allows for two cartridges and combines them at the tip in the same manner as the gun that is provided.

    If I use SCT-22 to fix a crack, can I be sure the crack won’t come back?

    Unfortunately no, Concrete moves throughout its life, it expands and contracts with temperature change, humidity levels, and because of the substrate, it is poured on. It is called a treatment because it fills the voids for an overlay to be applied, so the crack won’t transfer to the overlay. This said, it still could come back either in the same spot or near where it was on concrete floors.

    Will sealer stick to the SCT -22

    Yes, Most Dura-Kote sealers will stick to SCT-22 as long as it is sanded or roughed before it is applied. Sealers require a certain amount of “tooth” to allow for the proper bond. This is sufficient for Sct-22.

    Do I have to use the whole container or can I save some for another job?

    If you keep the plug that comes with shipping, you can re-insert it and save for another job. You will have to get a replacement mixing tube and cartridge dispenser to reuse. Which are available at SureCrete.

    How soon can I go over SCT-22 with a new coating?

    In as little as 15-20 minutes, SCT-22 is ready to be ground out to make a level surface and is ready at that point for a new coating to be applied.v
