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:

Use extra resin and wax paper to create a glass vase with decorative accents.

    1. I found out the hard way that it sticks to wax paper. Tried painting dry leaves and they stuck and broke. Would this have worked on a piece of polyethylene plastic ?

    2. ??? Can I put clear epoxy resin over cricut vinyl adhesive on a vanity counter top-the holographic vinyl adhesive- ???

    3. I was wondering if I could do a resin finish on a 6 foot folding table . The top is a bumpy plastic, I think . I want to make a lovely craft table . Does anyone know?

    4. I’m wanting to use a glass dome to preserve some wedding flowers in epoxy resin. If I line the dome first with parchment paper and brown packing tape to get the correct shape- then putting the flowers in and pouring on the resin would this work? Any advice much appreciated! Thank you

    5. Hi, once my resin coasters have hardened in the mould, would they be okay to remove and then place on a shiny
      ceramic tile to finish hardening for a couple of days or so please?
      Thanks, Sooz 😀

        1. Thank you! That’s great. I have so many spare tiles around – cheaper than using acetate sheets. Kind regards x

    6. I just made a mold from plexiglas the other nite and it stuck to it, bad! Getting it out of the mold was a pain, but didn’t affect the integrity of the resin, so I guess it’s half correct? Or I did something wrong, which is extremely probable!

  1. 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

    1. 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.

      1. Hi I’m new to Resin. Haven’t done a project yet I saw a YouTube channel where the person instead of using mold release used some regular Vaseline is that possible. I guess my question would be can you use regular Vaseline if you cannot find or buy mold release and if not is there something else you can use?

        1. Hello. I haven’t used resin before but I am thinking of using it to restore the top of a 1950s kitchen table. The top is Formica. Would table top resin stick to the formica? Thank you.

  2. 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.

    1. Dawn Howard : Do you have any photos ? Would LOVE to see these. I collect rocks, pebbles, flowers, leaves from every place I travel. And now have leaves from my son/grandson’s yard that I would LOVE to preserve in resin. Any tips ? Thank you !

    2. I’m new at this but saw figurines made out of wire and then covered in resin. What I want to know is can you wrap the wire in material then paint the resin on and last paint with paint . Also does resin stick too PVA glued material, cloth.

  3. 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?

      1. Hi Claire, I don’t have any experience using vinyl with resin. I would expect it to work, but you should test it first.

  4. 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

        1. Yes, glue stick glue (hot glue gun) works great for making barriers, and also for sealing the gaps/joins in plexiglass or foamboard barriers. Resin doesn’t stick to the cooled hot glue.

  5. Hello
    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

    1. My resin items never cure on the top. l am new to this.
      Am trying to report over them to see if it will harden them up. Will that work on the soft surface?

      1. You have to thoroughly stir the resin. Meaning scraping the inside of the container repeatedly I always stir mine for minimum 10 minutes. With the temperature being above 21 Celsius. And the day before and the day after With whatever you’re pouring in that room. The only reason why it’s not sticking is one of those two things. Or why it’s soft. You can do another pour over top. Usually that works. I have been doing table tops and River tables for 3 years. Used for different products. Find New Classic to be the cheapest and one of the best.

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

      1. I have a plastic box with a handle (looks like a lunchbox) that I am decorating with buttons and other items to embellish it including some glittery flat ornaments that I took apart. I was wondering if I can pour resin on top of it to give it a glassy finish?

  6. 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?

      1. One problem…the plastic pieces will float in the resin so, two pours may be needed. One part way to suspend the plastic below the top and then the second after the first cures to cover the trapped plastic.

  7. 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

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

  9. i want to do a glass window with sea shells and glass dots and sand etc. once i have everything glued down and pour the resin will it matter that the sea shells etc will be taller than the flat glass and will i be able to get an even coat without it running off the top of the shells and onto the glass surface. will it cause mounds to form between the seas shells. thanks for your answer in advance

        1. Will epoxy adhere to melamine serving tray? Or is there a way to get it to stick say, paint and glitter then epoxy as a thin protective clear layer?

  10. I would appreciate any pics or ideasto make resincrafts that i can sell . due to my disabilty i need to find a way crafting to provide income until i find a job. I’m thinking of charms, vases, earrings ext. Thanks

  11. Will epoxy resin stick to abs(Acrylonitrile Butadiene Styrene) plastic? I’m not verse in chemistry. My plan is to use clear coat epoxy resin(Art n Glow) to coat the ABS plastic keycaps for my keyboard in as thin a layer as possible using a silicone brush. That way the keycaps wont start to shine or ever wear away after long use since they’re coated in moisture resistant epoxy resin.

  12. does anyone know if resin will stick to polystyrene plastic sheeting? like the kind from a cheap poster frame from Walmart? or if so how to prevent its sticking to it once cured? im planning on making geodes on it if I can

  13. So, how about those plastic reusable bottles from walmart- the ones with the metal base and screw on lid that come in different jewel tones like teal, blue, purple, etc. for anywhere between 25 cents and a dollar? I want to seal on a vinyl saying so if it gets tossed in the sink(not dishwasher safe anyways) that the vinyl won’t peel off. Would I scuff? I had thought about trying htv but while it’s thick enough to not bend when squeezed, it’s still clearish plastic. Thanks for any insight!

  14. I have some cute metal cookie cutters that would be great for resin projects. Could I spray them with silicone spray and use as a resin mold?

  15. Hi
    I have made some resin trinket boxes.
    The problem is that the lids stick which makes the boxes unusable.
    I have tried spraying them with a gloss spray but the has not solved the problem.
    Do you have any idea what I can use to stop the lids stocking?
    Thanks 🙂

    1. Hmm. That’s a great question! Last time I worked with it, I don’t remember it being ‘waxy’ so I would guess yes. If you try, would you mind letting us know how it went?

  16. I have a project in mind, but I’m not sure it will work.
    I want to ‘glue’ pictures printed on regular printer paper to both sides of wooden disks and then put resin/ epoxy on both sides.
    Will it work? And do you have any tips? Thanks!

  17. does resin stick to thermoplastic? i thought about making a small mold with thermoplastic beads, since you can reuse them with hot water, but i’m scared it will stick.

  18. I need to use resin to layer sheets of fiberglass fabric to make a slightly stiff but flexible enough material to use for making lampshades. The same flexibility as rice paper used for Shoji screens but a little more translucent and of course more durable and resilient. What type of resin should I use to make sure the result can be bent to form a drum for my lampshades?

  19. Thanks, Katherine for answering my question but what I’m trying to do is to create a Shoji like or rice paper like fabric that once cured, it can be bent like rice paper or Shoji. I know people layer fiberglass with resin to make a hard and durable material but I am not looking for strength. I’m looking for flexibility and translucence so I can use it for lamp shades after the fiberglass layers are cured. So is this a matter of picking the right type of resin or is it a matter of the amount of resin used in between layers? The fiberglass material that I have is completely see-through and very thin and completely fragile. So I need to layer it to make it stiffer and less see-through. That’s why I’ll be layering that using resin in between layers but I’m not trying to build a boat or a car like all these fiberglass videos show!

    1. Won’t the fiberglass cloud up a bit if you lightly sand it with a high grit sand paper? Then lay your next layer on top?

  20. I have used flat river stone backsplash to tile my aquarium floor. I used black aquarium silicone as my “grout”. Can I pour resin over the whole thing to get a smooth surface now that the silicone has cured completely?

  21. I have mistakenly sprayed Elmer’s adhesive spray on a drawing on thick water colour paper, thinking it was a setting spray. The spray won’t fully dry and is sticky. Can I pour resin on top to fix it? Will the resin set on top of the adhesive spray properly?

    1. Hi Anna, I’m afraid the glue needs to be completely dry before pouring resin, otherwise the resin will cure cloudy, if at all.

    1. I have a piece of plywood inserted into a bar top there used to be ceramic tiles there. Took out all the tiles and painted the plywood with a rustoleum paint, put the plywood back in using a paintable silicone (gorilla) under the plywood to ensure there’s no dripping it didn’t seem sealed enough so I also siliconed around the edge of the plywood on top and painted the wood and silicone with the rust paint. My ‘plan’ is to lay pennies down and pour epoxy on top. Will it adhere to the painted wood and silicone? Thanks in advance!

  22. I’m new to making stuff out of resin. Because I am so new, I don’t want to use lots of money on things to make molds out of. So just to start out I’m planning on using a plastic drink bottle for a mold. will it stick to to bottle? Thanks!

    1. I bought a very old wooden piece that was hand painted in the 1930’s
      It’s oblong piece of wood hand cut and painted with oil paints I assume
      Can I use export resin to bring the colors back to life. Should I pretreat with thin layer of expound resin
      Or something else
      The surface is porous in som areas where the paint has faded.

  23. Hiya, I am making a mold for silicon and I am wondering what would be the best to use as a barrier for the joints. I have been looking at masking tape, Polyethylene tape, and wax paper tape, but I am not sure. What do you suggest?

  24. Do you know if Epoxy Resin sticks to PETROBOND? Petrobond is a tightly packed, oily sand normally used in casting molten metal objects. Thanks

  25. What is a good product to use on an irregularly piece of wood to seal the end…I have a piece of live edged cherry I want to resin pour into large cracks

    1. That’s a great question Briana. I haven’t tried. If you do, will you let us know if it does stick?

      1. Hi Denise, I’m not sure I understand what you are talking about. What kind of angel plastic do you mean?

  26. Hi
    I’am Catherine McGee and I didn’t ask Will resin stick to thick plastic. Like a angel. that was someone else, but I did ask if you could make a mold out of hot glue and would the resin come off of it.

  27. Hello there. I want to ask a question with apologies. They used something to sculpt the resin in a video on Pinterest. I did not quite understand what it was. it was transparent and they folded it and placed it on the tape. (they created hexagons to make a jewelry box.) I’m new to these things. Sorry if it was in the previous comments, I couldn’t be sure. Thank you for your help.

  28. Hi.
    What is the best way to wrap orgonite for shipping. I have tried everything …paper, bubble wrap, now i use expensive parchment paper but STILL it leaves marks on my perfectly polished pyramids which is gut wrenching as I work hard to get a glossy finish for my customers. Anyone have any tips?? As I’m out of ideas. The strange thing is I thought the parchment was working as I have had no complaints from clients??? but I had to unwrap one and saw that it was full of marks. I could cry!! lol

  29. I am trying to build a base layer of bright white that will be able to be cut and sanded later to add glow powder on top of. Glow powder mixed with resin isn’t impressive, but I think a dense layer of glow powder or supersaturated base with glow powder poured over fiberglass painted bright white might work. Any opinions?

  30. Aromatic Red Cedar!
    I cleaned surface of small slab with Acetone then applied resin. Dimples
    formed and other spots became bare…

      1. Hello. I have a large rock that I want to display that doesn’t have a flat surface on which to sit. I would like to create a resin base that part of the rock “fits” into and stands upright. Should I cover the rock in tytek tape and suspend in the resin? Or is there another way to this that might work better?

        1. Hi Cathy, that would make a nice display but would require a lot of work. Have you thought about creating a resin base on which you can display the rock?

  31. I am wanting to wrap my desktop in a carbon fiber vinyl wrap, will epoxy stick as a protective pour over the vinyl?

    1. Hi Peter, yes, resin will stick to graham crackers, but it will produce the same effect as getting them wet in water.

  32. I need to resin a wood table that originally had a polyurethane finish. Do I need to sand that off before I pour the resin or can I pour right over it?

    1. Hmm. That’s a great question Tami! I would sand it off to make sure the surface is even before applying resin.

  33. I have a polycarbonate hard shell suitcase. Two of the wheels were pushed up into the body, leaving cracks around the wheel bases, and rendering the suitcase unusable. Rather than toss it I thought I’d try applying fiberglass with resin. Will resin adhere to polycarbonate?

  34. I ‘m trying to make a round resin bowl as candle holder. The bowl is big as dessert bowl and i’m not sure how i can make a mold for it.

    1. Hi Sahana, I’m afraid resin isn’t suitable for a candle holder. Cured resin can melt when contacting a flame.
