Application

Surface Preparation:

  • Ensure the concrete is sound and free from oil, grease, dust, laitance, or other surface contaminants.
  • Saw cut the perimeter of the repair area 1/8” deeper than the repair depth to create a notched, reinforced edge.
  • The concrete surface must be mechanically abraded to a minimum CSP 5, as per ICRI 310.2 guidelines, and kept in a saturated-surface-damp (SSD) condition with no standing water.

Priming/Scrub Coat:

  • Clean all exposed steel reinforcing from rust.
  • Use SpecPrep SB for priming; apply with a spray or brush and apply the repair mortar wet on wet within the recommended open time.

Mixing:

  • Mix approximately 2.5 quarts of clean water per 50-pound bag of SpecCrete Plus SCC using a low-speed drill.
  • Add the water to the container first, followed by the SpecCrete Plus SCC powder.
  • Mix for 2-3 minutes until smooth; do not overmix.

Placement:

  • Trowel or screed SpecCrete Plus SCC into the prepared area, ensuring good contact with the substrate.
  • Level the material with the surrounding concrete and allow it to take an initial set before finishing by hand trowelling.

Curing:

  • SpecCrete Plus SCC is self-curing under most conditions.
  • In severe drying conditions, use a water-based ASTM C-309 compliant curing compound.

Packaging

Available in 50 lb bags and 3000 lb super sacks.

Shelf Life

12 months when stored in a dry facility away from direct sunlight. Excessive temperature differential or high humidity may shorten shelf life.
