Let’s first be clear: resin is epoxy resin. We don’t want to use any other type of liquid plastic, as it might not cure properly or have the same strength. For this reason, we do not recommend using PVA glue or casting resin.
That being said, you can make good use of a foil-covered surface with epoxy resin. You just have to know what material is covered by the foil and how best to apply the resin on top of it!
Epoxy resin – a hardening liquid plastic – can be used on cardboard, baking paper and aluminum foil without any issues. It will stick very well to these surfaces and bond permanently after curing!
Does resin stick to foil?
While working with resin is pretty straightforward, there are some key points to keep in mind. One thing you’ll want to pay attention to is the surface.
Metal foil, as well as some paper types, has a tendency to stick to the resin’s surface. This means that any mold you cast or workpiece you create will end up sticking to the foil rather than actually getting stuck in it.
This can be frustrating when you’re trying to remove something from your work area without damaging the material underneath. But it does not mean that all foil is bad for your work; it just needs a little extra care and attention for removing projects.
A trick I’ve used before was lining a square plastic bowl with aluminum foil before casting resin into it so that when I pulled out my project, which was actually quite solid, I could remove it completely from the bowl without touching anything other than the stainless steel side of the bowl itself (which also helped protect my tools).
A lot of times this technique works amazingly well, but if a project just doesn’t want to come out of its molds easily, there’s another way: use a dishcloth or paper towel instead of aluminum foil in your square bowl during casting and pull out your mold after allowing them to dry completely.
You may find that by using these methods you can get some really nice pieces from your casts without having any problems with cleaning up after each one

What doesn stick to epoxy resin?
Epoxy resin is a strong, durable, and versatile material that can be used for many different projects. The only downside to working with epoxy resin is that it doesn’t stick well to certain surfaces.
Read on to learn about the materials epoxy resin does not stick to and what you can use instead.
Does Epoxy Resin Stick To Metal?
It depends on the metal! Epoxy resin will not stick to aluminum foil or aluminum baking sheets in most cases. Since metal is an excellent conductor of heat however, you should never pour epoxy resin onto hot metal as heat can cause bubbles or crazing (cracking).
You could place a piece of hot metal directly into your mold before pouring your epoxy resin over it though!
Does Epoxy Resin Stick To Cardboard?
No, you cannot use epoxy resin with cardboard. Using this material will likely result in the cardboard becoming warped.
Does epoxy stick to aluminum?
Does resin stick to aluminum?
The short answer: YES.
I’m happy to tell you that epoxy resin will stick to aluminum, which means you can use it as more than just a mold! This is great news if you’re making something out of aluminum foil and want to reinforce it with resin.
Does resin stick to baking paper?
Nope, they don’t mix.
The resin is a little too thick to seep through the thin layer of aluminum foil. This means that it will not stick to the surface of your project.
Instead, you should use something more durable and water-resistant like wax paper or parchment paper which comes in handy for the pouring process as well as for curing finished pieces.
Can you use resin on cardboard?
This is one area where your best bet is to use a different material. Resin should not be applied to cardboard and there are many, highly valid reasons for this.
First off, it can cause the cardboard to warp or bend while the resin is curing since the cardboard itself is less rigid than other materials. Additionally, if you have a thick layer of resin on top of cardboard, it will absorb moisture from the air and can cause bubbling or cracking later on.
To avoid this problem altogether when working with epoxy resin and cardboard, try using thicker cardboards like Corrugated Fiberboard (which has two flat layers separated by fluting) instead of thinner varieties such as Kraft paperboard (a common type found in cereal boxes.)
This will help minimize any warping that might occur as well!
If you need to use cardboard for your project but don’t want issues with warping or bubbling, consider using a thicker version like corrugated fiberboard instead!
Can you use aluminum for resin?
First, let’s talk about why it’s not a great idea to pour onto foil in the first place. Aluminum foil is made of thin metal so it rips easily and is floppy.
You cannot cut it into a shape that will hold its form because it bends too much. The other reason is that aluminum foil will warp under the weight of the resin! Imagine if you poured enough resin to make a coaster, or even thicker than that there is no way it would retain its shape because aluminum bends really easily.
So what can you do instead?
Does resin stick to metal?
Yes, resin will stick to metal. But you need a primer, and not just any old primer will do. You must use a two-part epoxy primer that is made for aluminum substrates.
This type of primer chemically bonds with the metal. There are many brands of this kind of epoxy primer on the market, such as Zinnser’s Bullseye 1-2-3 and Rustoleum Automotive Primer Spray.
If you don’t use the correct kind of primer, resin will not stick to metal because there is nothing chemically bonding the two substances together.
How to prime your piece:
Before priming your piece for resin, give it a thorough cleaning and sanding. I used 400 grit sandpaper and wiped off all dust with rubbing alcohol before applying my epoxy spray primer in multiple thin layers (about 3 coats). Allow drying time between coats (as directed on the can).
What can stick to aluminum?
A list of things that stick to aluminum include:
- Epoxy resin: the strongest adhesive for most substances. This includes metal, plastic, glass, and even wood. The best part about epoxy resin is its flexibility and durability.
- Hot glue: glues have been around for decades and they are still going strong as a go-to adhesive. While they do not bond perfectly with some materials (especially plastic), hot glue is still a staple in craft projects because it’s easy to work with and inexpensive. It also works great on aluminum foil! Simply heat up your gun then squeeze out the glue onto your aluminum surface before applying pressure so that it adheres properly no need to wait for it to cool off first so you can get right back into crafting mode immediately after applying this type of bonding agent!
- Silicone: while silicone doesn’t hold up well over time, it can be used as an adhesive in certain situations where other glues might not work or be able to withstand high temperatures/forces like epoxy resins would need to withstand when bonding metal surfaces together without breaking down completely eventually under these conditions (which would cause irreparable damage).
You’ll want to use silicone with caution because any residue from using this type of bonding agent will remain on whatever surface was glued together – even if you remove all traces visible by eye before moving forward on finishing touches such as painting or polishing.”
Conclusion
So, does resin stick to foil? Yes, resin will stick to foil. However, it is important to note that if you are working with resin for the first time you might need a bit of practice first.
The best way to do this is by making a few small test pieces before you get started on your project. Now that you know the answer to “Does resin stick to foil?” You can enjoy all the fun of crafting with metal and resin without worrying about how it will turn out in the end.
