| Patching potholes, chips, cracks etc. in concrete surfaces (including runways) is typically done by making lots of sand into an epoxy and making a slurry 'epoxy cement'. Honestly, the sand provides most of the desired properties, the epoxy just holds it all together. While you can add sand to almost any of our epoxies, the favorite one is this product (mostly due to price). By adding about 15 pounds of sand to this 1.5 gallon unit of epoxy, you'll get about 2.5 gallons of epoxy/sand patching material. Users in hot summer time Texas/Mexico reported about 8 minutes of work time after mixing. It would a lot longer in cooler conditions. Runway repair crews found it OK to land planes on the patch after 24 hours. |
