Bull Float vs. Fresno (Key Differences)

Bull Float

  • What it is: The bull float is a magnesium blade that is initially run across the surface of the slab in the finishing process.
  • Purpose: Bull floats correct imperfections in the initial screeding process.
  • Size: Approximately 8” x 36” in size but sizes do vary.
  • Fresno TriStar Concrete


  • What it is: The fresno may look similar to the bull float, but its blade is made of tempered or “blue” steel. The fresno should only be used following the bull float.
  • Purpose: The fresno is applied after the bull float to better seal the surface of the slab.
  • Size: Approximately 6” x 36” but sizes do vary.
