The amount of powder to add depends on desired working consistency. The more powder you add, the thicker the mixture becomes. Fold mixture into itself repeatedly until desired consistency is attained (3-5 minutes or a minimum of 20 folds).
Applying - Apply by gloved hand to horizontal, vertical or inverted surface. Important; pot life and cure time are reduced with elevated temperatures
Stamp, Sculpt or Mold - Once in place, putty can be stamped using a rubber stamp (Rebound 25 silicone). Apply alcohol to stamp detail before using for precise detail and to keep stamp clean. Sculpt using gloved hands or tools. Putty can also be pressed into a silicone rubber mold to reproduce detail.
