  • Do not ingest. May act as a laxative. Seek medical attention if adverse symptoms are noted.
  • Avoid prolonged skin contact. Remove from skin with dry towel and then was with soap and water. Use rubber or plastic gloves if your skin is sensitive.
  • Use in a properly ventilated area.
  • Keep out of reach of children. Parental supervision recommended for children under 13.


Usage Instructions for Silicone Mold Putty

  • Gather equal parts of Part A and Part B by volume. Wash your hands or use separate tools to retrieve material from Parts A & B to avoid contamination.
  • Knead the two parts together for about a minute until streak-free and uniform in color. Roll into a ball shape.
  • Roll the putty ball over the original part that you want to duplicate. Start from the highest point of the original and work down. Work the putty into the crevices of the part to pick up all the details. Be sure to cover the complete part while leaving an opening underneath to pour your desired material into the finished mold. You have about 4 minutes working time before the combined putty will become stiff and harden.
  • Once your part is covered, let it cure for 30 minutes.
  • Remove the original part from the mold. If you find the part is hard to remove from an undercut or a detailed area, cut the mold to remove the part and tape it back together when you are ready to fill it.
  • Fill the mold with your desired material such as moldable plastic, resin, plaster, wax, clay, etc. The putty is not approved for food use. If using our Polly Plastics Moldable Plastic, follow the booklet instructions on how to melt and color the plastic.
  • You can reuse your mold multiple times but once Parts A & B have been mixed together, they cannot be separated or re-melted.
  • Store unused portions at room temperature in their original containers, with the lids securely closed.
