UNIFIX is designed specifically for use with CSI casting powders.
Lightly spray evenly over the impression with UNIFIX which will thereby penetrate the porous structure of the soil and sand to fix it. It doesn't matter whether the impression is moist or not.
The surface of the impression will then be sealed allowing you to pour the casting material (Denstone or Crownstone) into it and thereby casting the perfect mark.
