Application

Surface Preparation:

  • Ensure the concrete is sound and free from all foreign materials, including oil, grease, dust, laitance, and other surface contaminants.
  • Saw cut the perimeter of the repair area 1/8 inch deeper than the repair depth to create a notched, reinforced edge.
  • Mechanically abrade the surface to a minimum Concrete Surface Profile (CSP) of 6 as per ICRI Guideline 310.2.

Priming/Scrub Coat:

  • Clean all exposed steel reinforcing of rust and coat with SpecPrep SB.
  • Ensure prepared concrete is in a saturated-surface-damp (SSD) condition and prime with SpecPrep SB using a spray or brush. Apply the repair mortar wet on wet or within the recommended open time.

Mixing:

  • Mix 7.0 to 9.0 pints of clean water per 50-pound bag of Total Patch using a low-speed drill or mortar mixer.
  • Add water to the container first, then gradually add the Total Patch powder.
  • Mix for 2-3 minutes until smooth, only mixing what can be used within the setting period.

Deep Applications:

  • For heavy traffic areas over 2 inches, extend Total Patch with clean, SSD, 3/8 inch aggregate up to 60% by weight. Adjust the total mixing water based on the moisture content of the aggregate.

Placement

  • Trowel or screed Total Patch firmly into the prepared area, ensuring good contact with the bonding surface.
  • Allow the material to set initially before finishing by hand troweling. Excessive troweling is not required.

Packaging

  • Available in 50 lb bags and 3000 lb SuperSacks.

Shelf Life

  • 12 months when stored in unopened containers in a dry facility between 45°F and 90°F.
