Concrete Mender™ Safety Yellow

Roadware  Concrete Mender™ Safety Yellow  is a high-penetration two-part hybrid urethane that may be combined with sand to form a tough instant polymer concrete. This nearly water thin formula is designed to penetrate deep into the host concrete creating high-performance saturation bond, reinforcement of the repair area as well as permanent floor marking.

Roadware Concrete Mender™ Safety Yellow produces polymer concrete markings that absorb shock and transfers the load of heavy traffic without cracking or dis-bonding. It is highly chemically resistant and can be applied in a wide range of temperatures. It is excellent for industrial floor markings in cold storage and freezer warehouses.


  • Cures traffic ready in about 10 minutes at 70°F (21°C).
  • Works in freezers. May be used at temperatures below -20°F (-28°C).
  • Will not become brittle and crack apart like epoxy.
  • Will not peel off like paint.
  • Complete saturation bonding with the concrete with Microdoweling™.
  • Highly chemical resistant.
  • Bright yellow color when cured.
  • Easy to clean
  • Based on Roadware 10 Minute Concrete Mender™ with a 20 year track record in repairing concrete floors.


  • Less down time
  • Save money with a permanent solution.
  •  Increased safety
