New binder in powder form developed to fix all pigments in an aqueous solution. Fill a spray bottle with a teaspoon of Colortricx or Powderfix, add a little bister or not for a different undertone, add 2 to 4 teaspoons of Powderfix and add 50 ml of boiled and chilled water. Shake well and ready to use. This way you can make an infinite number of colors yourself in spray bottles.
