Surfaces resin won’t stick to – what surfaces will resin not adhere to

Surfaces resin won't stick toResin makes a great glue but sometimes you need surfaces resin won’t stick to.  That information is not only helpful in knowing what makes a good resin art and crafting surface but knowing a little bit about what resin doesn’t stick to is useful in getting resin to do some neat things.

Mold release.  We use mold release to keep resin from sticking to molds.  Plus, it is great for prolonging the life of molds.  It lets you demold resin jewelry and crafts without having to distort and pull at the mold as much, which can cause warping and microtears that impact future castings.

Wax.  Whether it’s candle wax or wax for lost-wax jewelry casting, resin will not stick to it.  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 to cure, then pull the wax away.

Polyethylene plastics.  Disposable plastic sheets for painting and sandwich bags both contain polyethylene.  Resin will not stick to these which makes them a great protector for your resin art and crafting area.  On the other hand, they are rather inexpensive and can be thrown away if you don’t want to clean them up after completing your resin project.

Anything with a greasy surface.  For example, if you have metal sheet that was used for an industrial purpose and has a thick waxy, oily, or greasy coating, resin is unlikely to bond itself to the surface.  Remove the grease however and the resin will stick to it like glue.

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 is allows it to be a good molding material.  The exception to this is if you pour more silicone.  If you don’t use a rubber to rubber mold release, the silicone will stick to itself creating a large block of silicone.

Polyethylene or polypropylene plastics.  These are the basis of many plastic molds for resin.  Use with a mold release to make sure you have the best success.

Painter’s tape of packing tape – either clear or brown masking tape.  This is incredibly useful if you want to create open-backed bezel pendants with resin.  Once the resin is cured, peel the tape away!   You can see why the tape is important in this article:  how to make 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 creating a sharp edge.  You can see the technique in this article on how to make a 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 can peel away from the surface.  Here’s a great leftover resin project:

My experience is most resins and glues do not stick to melamine the white shelving materials. so it makes it an easy surface to use as a work area or portion of a mold for reverse molding applications

Katherine Swift

While that has been my experience sometimes, I haven’t been lucky enough to have that happen all the time. I use a mold release when using melamine.

I preserve leaves and flowers in resin. Resin will not stick to leaves or flower petals that have a waxy or oily surface. However, this can result in cool looking resin leaves – the waxy/oily leaves basically function as a mold. This trait is something I plan to experiment with more in the future.

Will resin stick to whiteboard? Like the kind, you use white erase markers on? Could you use White Erase markers on resin and would they wipe off?

Resin won’t stick to tyvek tape. We use it to line our borders for resin tables.


I would like to use resin in little sterilized glass insulin bottles…are there any precautions you can offer or would it be completely safe

Does epoxy resine stuck with itself !
I have a silicone mold and i want to make it in two piece, with an empty space inside (creating it with plastic )
Thanks in advance

You will need to cast it as two separate pieces if you don’t want them to stick to each other.

I would like to use resin in table tops as a thin strip between wood pieces, because of the cost of resin I was thinking of recycling old pieces of plastic cut into pieces and put in the gaps then resin poured over to bulk up the gaps, would the resin stay solid or would the plastic bits make the resin fragile?

Dave Sherby

If the plastic is a material that resin will stick to it could actually make the resin stronger. The plastic would act as an aggregate likes stones in concrete. Even if it doesn’t stick to the plastic you should be fine as long as you don’t fill the gap eith too much plastic

Will resin stick to mica? Specifically could it be use to fuse sheets of mica to one another or to seal edges?
