Surecrete Flowable Epoxy Concrete Crack Repair SCT-EP


About

SCT-EP serves as a wonderful treatment product to help reduce the shadowing through of cracks into the next layer of decorative overlay or coating product as well as to minimize the amount of movement and subsequent cracking from the same location in your concrete slab.

Popular Uses:

  • Cracked Concrete Slabs
  • Damaged Interior Residential Floors
  • Hairline concrete cracks in large retail centers
  • Non-structurally damaged exterior concrete
  • Older Interior Concrete Floors
  • Exterior Building Walls
  • Residential Living Area Substrates
  • Concrete Driveways and Walkways


Specs

  • Coverage: 3 gallon = 0.4 cubic feet
  • VOC Rating: 0 g/L
  • Shelf Life: 1 year in original unopened container
  • Appearance: Amber Liquid

    Instructions

    TEMPERATURE/CURE

    Avoid application on extremely cold or hot days or during wet, foggy weather. Basic rules include:

    • Apply with ambient and surface temperatures ranging above 50°F (10°C) and below 90°F (32°C) and that will remain within ranges for at least 12 hours following application.
    • Relative humidity should be below 75%.
    • Ready for overlay usually overnight, approximately 8 hours.


    EVALUATE / SET EXPECTATION

    Establish if crack to be treated is structural or static.

    • Structural Cracks
      • Likely larger than 1/8” in width
      • May be “spitting” aggregate
      • Travel full length of slab
      • Travel from control joint to control joint
      • Backer rod or sand may be used to partially fill large deep cracks. Finished depth of epoxy must be at least 1” (2.5 cm).
      • Treatment will minimize return of crack in overlay
    • Static Cracks
      • Less than 1/8” in width
      • Do not travel full length of slab
      • Do not travel from control joint to control joint
      • Treatment likely to be successful

    Large spalls or voids in slab, especially those that are full depth of concrete will likely have a structural crack at perimeter. Damp or wet cracks cannot be treated.

    CRACK CHASING

    • With 4” hand-held electric grinder equipped with a diamond “crack chaser,” “V” blade grind the full length of the existing crack.
    • Be certain to engage the blade to the full depth of diamonds.
    • Remove dust from the crack with brush and forced air (leaf blower or air compressor).
    • Select a mixing vessel that will not melt (e.g. steel or thick mil plastic) from catalyzed material.
    • Pour 1 part B into 2 parts A.
    • Mechanically mix both parts A and B with “Jiffy” style mixer blade for 2 minutes at medium speed with a Jiffy style mixer at medium speed to help prevent air entraining.


    APPLICATION

    Planning

    1. Prime the crack by brushing a thin coat of blended product with a chip brush into all edges of “V” joint.
    2. Add clean, dry, silica sand into the same mixing vessel containing the blended SCT-EP. Add sufficient sand to achieve a thick slurry with the consistency between honey and peanut butter.
    3. Mechanically mix slurry with a “Jiffy” style mixer blade.
    4. Pour and margin trowel the mixture into the v-joint.
    5. For proper bonding of an overlay, sprinkle a small amount of sand on top of the epoxy before it completes its cure. This sand will help to create a mechanical bond with the overlay by increasing the surface bonding area.
    6. After curing, product may be finished flush with a handheld grinder equipped with a “Zek” style blade.


    SCRATCH COAT

    Following the treatment of the crack, just prior to the installation of an overlay (if used), a scratch coat must be installed over the treated crack.

    • Allow SCT-EP to dry overnight, approximately 8 hours
    • Dampen the slab area adjacent to both sides of the treated crack.
    • Trowel a tight coat of SureBroom (see TDS) across the full length of the crack.
    • Total width of the scratch coat should be approximately 12” (30 cm).
    • Carefully feather the edge of the troweled material with trowel or damp sponge to leave no ridges.


    CLEAN-UP

    Before SCT-EP dries; spills and tools can be cleaned up with a solvent such as xylene or acetone.

    Effectively treats static cracks in concrete or minimizes their return in active, structural cracks. SCT-EP may be used prior to the application of an overlay for concrete or as a stand-alone treatment for cracking.

    • Effectively treat cracks
    • Minimize subsequent cracking
    • Easier and less expensive than alternatives
