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.

Have you found other surfaces resin won’t stick to?

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 ?

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

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 😀

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

Reply
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.

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?

Not true, I’ve had a bad experience. But later turned it into a good one by decorating the plexiglass

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.

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?

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.

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?

Reply
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 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.

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!

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?

Reply
Ozzie

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!

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?

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?

Reply
Katherine Swift

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

Reply

Hi Sheila, I wouldn’t expect that to work very well since leather is flexible.

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!
