Ask anyone who has made resin crafts. Drips of cured resin adhere pretty easily to carpets, hair, and your favorite shoes.
But sometimes you need surfaces resin won’t stick to.
1. You know what works to protect your resin art and crafting surface.
2. Knowing what resin doesn’t stick to helps get the resin to do some neat things. Like making resin beads.
3. It’s a fun party trick.
Not really on the third one. But resin is a fun adult night craft project to do with your besties.
What surfaces won’t resin stick to?
Mold release. You want to use mold release to keep epoxy resin from sticking to molds. Plus, it is excellent for prolonging the life of molds. It lets you demold resin jewelry and crafts without distorting and pulling at the mold. This causes warping and microtears that impact future castings.
⭐️ BONUS: Here are three reasons why I always use resin mold release.
Wax. Resin will not stick to it, whether it’s candle wax or lost-wax casting wax. The same goes for car and furniture wax. This is useful if you want to create a void in your resin charm or casting. Pour the resin around the wax, allow it to cure. Then pull the wax away.
Polyethylene plastics. Disposable plastic sheets for painting and sandwich bags both contain polyethylene. Epoxy resin will not stick to these, making them a great protector for your resin art and crafting area. They are also inexpensive. You can throw them away if you don’t want to clean them up after making your epoxy art.
Anything with a greasy surface. Anything that has a waxy, oily, or greasy coating, will not bond to resin. But, remove the grease, and you’ll turn the surface from one that resin won’t stick to into surfaces resin will stick to.
Silicone. So, this is a little bit of a trick answer because silicone is a resin itself. But the good news is that other resins will not stick to it, which makes it perfect for resin molds. The exception to this is if you pour more silicone into the silicone mold. If you don’t use rubber to rubber mold release, the silicone will stick to itself, creating a large block of silicone. Whoops.
Painter’s tape or packing tape This resin hack is useful to create open-backed bezel pendants with resin. Once the resin cures, peel the tape away.
⭐️ BONUS: See why the tape is essential when making open-backed resin pendants.
💡 Pro tip: Use painters’ tape to mask off a surface. If the resin spills onto the tape, let it partially cure. Then peel away the tape. You can see the technique in this article on resin cheese board.
Wax paper, parchment paper, or freezer paper. When taped to a surface, leaving the waxy side up, the resin will cure but peel away from the surface.
⭐️ BONUS: Use extra resin and wax paper to create a glass vase with decorative accents.
