FasTrac Shotcrete Tech Data

How to Apply

Surface Preparation

  1. Remove all dirt, dust and other bond-inhibiting materials.
  2. FasTrac Shotcrete products should be installed in accordance with the provisions of the national and local building code and The American Concrete Institute’s recommended practices (ACI 506R-90, “Guide to Shotcrete”).
  3. Clean, potable water need to be used for wet and dry processes of application. Prior to application of the
    FasTrac Shotcrete, the substrate should be clean and evenly moisturized, however, not saturated.

1.Mix FasTrac Shotcrete with approximately 4.80-5.75 pts. (2.27-2.72 liters) of water per 50lbs (22.7kg) bag. It is recommended to prepare the job mock-ups by contractor and tested before working on the project.
