My part is very hard to get out of my one piece silicone mold. Is there anything I can do to help it release easier?Updated a month ago
Yes! To aid in the release of silicone rubber from your mold box or your original, use a small amount of rubbing alcohol. The rubbing alcohol will make the cured silicone very slippery and will help seperate the silicone from the other surface. After you remove the original, dry out the excess alcohol with a paper towel or dry cloth. Be sure to warm and dry out the mold COMPLETELY before pouring resin into the mold to avoid the alcohol from contaminating and affecting your next cast piece. You can also use rubbing alcohol to assist removing resin pieces out of a silicone rubber mold. Use the same process as mentioned above for removing your mold from the original and the mold box. Make sure the resin is cured before putting the alcohol in the mold.
