JanetsCandles Posted August 9, 2012 Share Posted August 9, 2012 Apparently, 3M duct tape will stick to silicone and polyurethane molds. And it works to stop up a leak in said molds. I haven't gone so far as testing to see if it will seal a major cut, but we've got a couple of molds that have taken more than a bit of abuse and this is making them last a little bit longer. That makes for a happy candle maker Figured I'd pass on the info for anyone else that has silicone molds that may need the info. Quote Link to comment Share on other sites More sharing options...
Sharon in KY Posted August 9, 2012 Share Posted August 9, 2012 It didn't work for me to cover the hole for the wick in a metal mold. Used the foil tape instead, it works great. Quote Link to comment Share on other sites More sharing options...
JanetsCandles Posted August 9, 2012 Author Share Posted August 9, 2012 I imagine the metal mold would just melt the adhesive. The silicone molds don't get that hot, so it works there. Quote Link to comment Share on other sites More sharing options...
ChrisR Posted August 9, 2012 Share Posted August 9, 2012 I have duct tape on the bottom of 4 of my seamless aluminum molds, it's been there for several years and still holding strong - no leaks! Quote Link to comment Share on other sites More sharing options...

Getting a few extra pours is huge with those spendy molds. Quote Link to comment Share on other sites More sharing options...
