How to Apply
Surface Preparation (See ICRI guidelines)
- Concrete must be sound and fully cured (28 days).
- Saw cut the perimeter of the area being patched into a square with a minimum depth of 1/2″ (13 mm).
- Remove all unsound concrete and roughen the surface to min. 1/4″ profile amplitude.
- Remove all laitance, oil, grease, curing compounds, and other contaminants that could prevent adequate bond.
- The concrete substrate should be saturated surface-dry (SSD), without standing water, before application.
- Blend with aggregate and apply the mixed material onto the prepared saturated surface-dry (SSD) substrate by trowel or screed. Ensure proper consolidation of the mortar and compaction around reinforcing steel. Minimum application thickness is 1” based on a 3/8” max. coarse aggregate. Finish the completed repair, as required, taking care not to overwork the surface.
Reinforced Steel
Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 03730 “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.”
Mixing
Approximately .33-.34 water to cementitious materials ratio by weight. Conduct field trials to verify proper slump (approx. 8”) yield and a thoroughly mixed product.
Working time– Approx. 15-25 min

*Compressive strength test was done on extended (with 3/8” rock and standard concrete sand) mix.
Curing
Cure immediately after finishing. Use a curing compound that complies with ASTM C 309. In extreme heat, keep the patches covered and damp
Clean Up
Clean tools and equipment with clean water immediately after use. Cured material must be removed mechanically.

Risks Product is alkaline on contact with water and may cause injury to skin or eyes. Ingestion or inhalation of dust may cause irritation. This contains free respirable quartz, which has been listed as a suspected human carcinogen by NTP and IARC. Repeated or prolonged overexposure to free respirable quartz may cause silicosis or other serious and delayed lung injury.
Precautions KEEP OUT OF THE REACH OF CHILDREN. Prevent contact with skin and eyes. Prevent inhalation of dust. DO NOT take internally. Use only with adequate ventilation. Use impervious gloves, eye protection and if the TLV is exceeded or is used in a poorly ventilated area, use NIOSH/MSHA approved respiratory protection in accordance with applicable federal, state and local regulations.
First Aid In case of eye contact, flush thoroughly with water for at least 15 minutes, and seek medical attention. In case of skin contact, wash affected areas with soap and water. If the irritation persists seek medical attention. Remove and wash contaminated clothing. If inhalation causes physical discomfort, remove to fresh air. If the discomfort persists, breathing difficulty occurs, or if swallowed seek medical attention. Refer to Safety Data Sheet (SDS) for further information.
