This modeling sealant is essential for making your polycarbonate molds waterproof. Reusable and easy to apply, it can also be used to delimit your molds if you want to create creations with several colors.
- To use this sealant, simply pass your wick through the hole in your polycarbonate mold, leaving the end of the wick sticking out. After kneading the paste, apply it to the hole to ensure a seal.
