Refrigerated Warehousing & Grocery Distribution
If your business is refrigerated warehousing or grocery distribution, Restorer is the premier concrete repair product for keeping your floors in top condition. 15 min Concrete Restorer will cure at temperatures well below -20 degrees F. ( -28 C) in just a few hours. You can repair cracks, spalls, slabs, joints, and surfaces while the warehouse is in service.
Cold environments such as walk-in freezers and refrigerated warehousing pose difficult challenges for repairing concrete. In temperatures less than 0° F, most repair materials become unworkable and may take many hours to set and cure. Most epoxies are not usable below 32° F. Concrete Restorer has been used in temperatures as low as -30°F below freezing. Listed below are some problems and solutions for working in cold environments.

Frost:
Frozen moisture in the concrete will act as a barrier between the repair material and the pours of the concrete. Most repair materials will
try to bond to the frost coated concrete. When the temperature increases, the frost melts and so does the bond.
Working Conditions:
Working with materials in the cold is challenging to both man and materials. Mixing epoxies or mortars in the cold is especially challenging. As the temperature decreases, the viscosity and flow rate of these materials increase making them harder to mix and much more difficult to work with.
Curing
With most materials, cure times in cold environments are extended significantly. A product that normally cures in an hour at room temperature may take as much as 12 hours in a cold environment. Some materials may not cure at all before actually freezing solid. The extremely low viscosity and rapid cure times of Accuflex 15 min Concrete Restorer products make them excellent for cold environment application. Successful repairs are routinely made at temperatures below -20°F in freezer floors.
Preparation:
repair cracks, joints, and spalls according to standard recommended methods. Make every effort to remove any moisture from the repair area. A propane torch or heat gun is very helpful in removing frost and moisture. In extreme cold, it is necessary to heat up the concrete prior to application.
Application:
Keep material and sand or aggregate warm. Place materials in a warm area (between 70°F and 90°F) prior to application.. Apply material as directed. It is a good practice to pre-wet all concrete surfaces with material before the introduction of sand. This insures full penetration and a strong bond.
Accuflex Concrete Restorer is designed to cure in approximately 15 minutes when all components involved are at 70° F. In cold environment, the cure time depends on the temperature of the material, the temperature of the sand or aggregate if used, the volume of the repair, and the temperature of the
concrete.
