How to make molds
This product is mixed by hand. If you choose to wear gloves, wear vinyl gloves only.
Latex gloves will inhibit the cure of the rubber.
Simply measure equal parts by volume of part A and part B into two separate equal sized balls.
Knead part A and part B together with your hands until uniform in color (light blue). The heat from your hands will help activate the product. Once the color is uniform, you are ready to begin your mold
