SURFACE PREPARATION:
Concrete repair surfaces should be clean, sound, and free from any materials that may inhibit bond such as oil, asphalt, curing compounds, acids, dirt and loose debris. Roughen surface and remove all unsound concrete. Immediately prior to placement the repair surface shall be thoroughly saturated with no standing water (ssd).
MIX & APPLY:
The working time for Rapid Set® DOT Repair Mix is 10-20 minutes at 70F. Setting time is longer at lower temperatures and shorter at higher temperatures. The working time may be extended by using chilled materials and/or Rapid Set® Set Control®. In cold weather heated materials may be used to accelerate the set and strength development.
Place material quickly and strike off with a screed. Apply desired finish. Begin water curing immediately after final finishing. For more details, contact CTS.
