• Broken, chipped, and spalled concrete repair
• Vertical and overhead patching applications
• Precast and prestressed concrete repair
• Bridge beams, box culverts, concrete pipe, and architectural concrete details
• Jobs where color blending with existing concrete matters

Key Features

• Approximate initial set: ~20–30 minutes
• Color: Dark Gray
• Carvable, shaveable, and featheredge-capable after initial set
• Can be mixed with potable water or Kaufman SureBond latex modifier
• Professional-use repair material for contractor applications

Material & Application Notes

Mix 50 lb of HiCap with approximately 4.5–5 quarts of potable water. For best adhesion, Kaufman recommends priming with SureBond, SureWeld, or the proper SurePoxy bonding agent. Do not retemper after mixing.

Why Contractors Choose It

Extended working window for warmer weather, larger patches, or more shaping time. For Pro Contractor Supply customers, HiCap is a strong fit when the repair needs to set fast, shape cleanly, and blend into existing concrete work without slowing down the crew.
