Epoxy resin for crafts: the definitive guide for creative projects 🎨

Hey there, makers! I'm Mr. Resin, and if you've ever found yourself hypnotized staring at those glossy pieces that look like glass, with flowers or psychedelic colors trapped inside, wondering: "but how on earth is that done?", you're in the right place. The answer is none other than epoxy resin.

With this liquid marvel you can encapsulate memories, create jewelry that nobody else will have, coasters with unique designs, dioramas that look real... basically, the only limit is your imagination. Today I've got you covered — let's dive headfirst into this universe!

What is epoxy resin and why is it going to change your crafting?

Let's get straight to the point. Epoxy resin (or epoxy, between friends) is simply a two-liquid system that, when combined, works like magic. You have a resin (Part A) and a hardener (Part B). When you mix them in the correct ratio, a chemical reaction is triggered that turns them into a solid plastic — super resistant and, generally, as transparent as glass.

This reaction releases heat, which is what we call "exothermic." Don't worry if you notice the mixing cup getting a little warm. That's the sign that the spell is working! 😉

Now, a word of warning: it's crucial that you don't confuse epoxy resin for crafts with the resins for 3D printers that I use for printing. They're distant cousins, but they really don't get along.

To make it crystal clear, here's a comparison table I've put together. No confusion possible!

Key differences between epoxy resin and UV resin for 3D printing

As you can see, each one has its own playing field. Mixing them up is a beginner's mistake I want to save you from right from the start.

I say this from experience: what I love most about epoxy resin is that it adapts to everything. You can pour it, paint with it, encapsulate objects... It's like having a creative superpower in two bottles.

The chemistry, but without putting you to sleep

Relax, you don't need to dust off your old school notes. The only thing you need to burn into your memory is the mixing ratio. This is commandment number one for the resin crafter.

Each manufacturer will tell you theirs, usually by weight (which is the most precise) or sometimes by volume. If the label says "1:1 by weight", it means that for every 100 grams of resin (Part A), you need exactly 100 grams of hardener (Part B). If it says "2:1", that's 100 grams of resin for every 50 grams of hardener. Simple, right?

And what happens if you wing it and do it "by eye"? Total disaster. The reaction won't complete and you'll end up with a sticky, mushy mass that will never cure. That's why I'm telling you that a digital precision scale is not optional — it's your best ally in this adventure.

With this material, a world of possibilities opens up for you: amazing water effects for your scale modeling dioramas, one-of-a-kind jewelry, coasters to give as gifts, or even a glossy protective finish for your 3D printed miniatures. Imagine encapsulating a tiny printed Grogu inside a keychain that looks like it's made of crystal.

The potential you have in your hands is incredible. In this guide I'm going to tell you everything you need to start creating without fear and with spectacular results. Let's get to it!

How to choose the right type of epoxy resin for your project

Alright, maker! You now know what epoxy resin is and how it differs from the resin we use for 3D printing. Now comes the million-dollar question: which one do I buy?

Walking into a store (physical or online) and seeing that wall of bottles can be a little overwhelming, I know. Don't panic! Choosing wisely is, literally, 50% of your piece's success, and I'm here to let you in on the secrets. Really, it all comes down to a couple of key concepts that, once you get them, instantly turn you into a pro shopper.

Viscosity: the key to avoiding bubbles or creating domes

Viscosity is simply how thick or liquid the resin is. Think about the difference between water and honey. That's exactly it. And trust me, this characteristic changes EVERYTHING in your project.

• Low viscosity resins (liquid like water): These are my favorites for getting started and for almost anything you pour into a mold. Being so fluid, they seep into every last nook and cranny, and best of all, those pesky air bubbles rise and escape with pleasing ease. They're fantastic for:

  • Molds with fine details: A complex figure? Chess pieces? This is your resin.
  • Encapsulations: For submerging dried flowers, glitter, or any treasure you want to immortalize.
  • Thin layers: Such as a first sealing coat over a surface.

• High viscosity resins (thick like honey): These are denser and their superpower is that they don't spread and run. They tend to create a domed surface due to surface tension, a trick known as "doming" or the dome effect. Great for:

  • Creating the dome effect: Perfect for the final coat on keychains, pendants, or coasters, giving them that professional magnifying-glass-style finish.
  • Coating surfaces without a mold: If you want to varnish a painting or a photo, this resin will stay in place without spilling over the edges (if you apply it with a bit of skill, of course).

My cheat sheet is simple: Mold with fine details? Low viscosity. Magnifying glass or dome effect? High viscosity. No mystery to it!

UV protection to keep your creations from turning yellow

This point is sacred. CRITICAL. Epoxy resin, due to its chemistry, tends to yellow over time when exposed to sunlight. It's its kryptonite. A piece sitting on a shelf away from the window won't suffer much, but if you're making something that will live near light or outdoors, you need the resin to include UV stabilizers.

Luckily, almost all good craft resins already include them as standard, but don't take it for granted — keep an eye on the label. A resin with good UV protection will maintain that crystal-clear transparency for much longer. Seriously, don't cut corners on this one.

Fast curing for the impatient (with a few caveats!)

You'll also come across "fast-curing" resins out there that promise to have your piece ready in 12 hours instead of the usual 24-72. Sounds tempting, right? Especially when the anxiety kicks in. But hold on.

A faster chemical reaction generates a lot more heat (remember that resin heats up as it cures). This is a real problem with large or thick pours, because it can cause cracks or yellowing from the excess temperature.

My maker-to-maker advice: use fast-curing resins only for small projects and thin layers. If you're going big — like a table or a resin block — always go for a standard or slow-curing one. It'll manage the heat in a much smoother and more controlled way.

As you can see, it's not about one resin being "better" than another — it's about finding the perfect dance partner for your project.

Essential tools and safety when working with resin

Hold your horses, artist! Before you dive in and start mixing potions like an alchemist on a creative high, we need to talk about something sacred: your safety. Trust me, I know from experience that this is the step people skip most cheerfully — and it's the number one beginner mistake.

Working with epoxy resin for crafts is fantastic and completely safe, as long as you use a bit of common sense. Resin in its liquid state is a chemical product and needs to be treated with the respect it deserves. But don't panic — I've put together a checklist so you don't miss a thing.

First things first: your protective gear

This isn't a suggestion — it's the golden rule. I've already made every mistake in the book so you don't have to, and my mission is to make sure the same doesn't happen to you. Before you even open the bottles, make sure you have on hand:

• Nitrile gloves: Non-negotiable! Direct and repeated skin contact can lead to irritation or an allergy that ruins the hobby for you forever. Latex gloves give up against some chemicals, so nitrile is your best ally. Plus, you don't lose any sensitivity.
• Safety glasses: A splash in the eye is one of those experiences I can guarantee you don't want on your résumé. A simple pair of glasses is more than enough to avoid a nasty scare.
• Good ventilation: Always work in a room where air can circulate. Open the windows wide. If your workspace is more of a cozy nook or ventilation is limited, an organic vapour respirator is your indispensable companion.

As I always say: "Better safe than sorry... or sorry in an emergency room". Don't risk it — your future self will be eternally grateful.

The tools that will make your life much easier

Once you're properly protected, it's time to set up your arsenal. You don't need a NASA laboratory, but these tools are what separate a professional finish from a "well, not bad for a first attempt...".

This is my foolproof starter kit:

• Digital precision scale: The key piece of the whole puzzle, almost as important as the gloves. The ratio between resin and hardener has to be exact. Measuring "by eye" is the perfect recipe for a sticky disaster that will never cure.
• Reusable silicone cups: They're pure magic! You mix in them and, when the leftover resin dries, it comes out in one piece. You say goodbye to generating a mountain of plastic cups.
• Stirring sticks: Silicone ones are also great because you can use them a thousand times, although classic wooden popsicle sticks also do the job. The important thing is to have a few on hand.
• Kitchen torch or a long lighter: Your secret weapon against those pesky bubbles. A quick and light pass of heat over the surface of the freshly poured resin and poof! The bubbles rise and pop, leaving a finish as smooth as a mirror.
• Silicone mat: To protect your work table from accidents and spills. Cured resin peels off silicone effortlessly, which makes cleaning a breeze.
• Silicone molds: The life of the party! They come in every shape and color you can imagine, from coasters to chess pieces. The quality of the mold makes a big difference in the final shine of your piece.

With this basic kit, you're more than ready to start creating without fear. In fact, many stores already sell starter kits with all the essentials. If you want to take protection a step further, I recommend taking a look at these nitrile gloves specifically designed for precision work.

The world of resin crafts has exploded and the number of tools is almost infinite. If you're curious, you can discover more about the possibilities of the material in the epoxy resin guides on Brildor.com. Now you're truly ready to get into action!

The step-by-step process for mixing and pouring resin like an expert

Now we're really getting into it, maker! We've reached the moment of truth, time to get your hands dirty (with gloves on, of course!). You've already got your workspace set up and your safety gear ready. It's time to leave the theory behind and start creating pure magic.

I've spent years perfecting this process, stumbling into every possible mistake so you don't have to. Trust me, I've seen it all. If you follow these steps, I promise your first pieces with epoxy resin for crafts will be worthy of framing. Let's get to it!

Step 1: Preparation and the sacred measurement

First things first: have everything within reach. Your scale, the silicone cups, the stirring sticks and, of course, clean and dry molds. Place the mixing cup on the scale and press the tare button to zero it out.

Now, with great care, pour the resin (Part A) up to the amount you need. Right after, with surgical precision, add the hardener (Part B). It's essential that you strictly follow the ratio indicated by the manufacturer. If it says 1:1 by weight, for every 50 grams of Part A, you need exactly 50 grams of Part B. Not one more, not one less.

A friendly tip: measuring "by eye" is a one-way ticket to a sticky disaster that will never cure. Your precision scale is your best ally in this adventure. Treat it accordingly!

Step 2: The art of mixing without throwing a bubble party

With both components in the cup, comes the key moment: mixing. And no, it's not like beating eggs for an omelette. Forget about speed. Here the key is to move the stick slowly, but deliberately.

Scrape the sides and bottom of the cup thoroughly. Make sure not a single drop of resin or hardener is left unincorporated. Stir for about 2-3 minutes, drawing circles, figure-eights, and moving the stick up and down. You'll notice the mixture becomes slightly cloudy and "stringy"; don't be alarmed. Keep stirring slowly until it becomes crystal clear again.

Before continuing, a vital reminder. These three safety pillars are non-negotiable.

Burn it into your memory: ventilate, protect your eyes and hands. It's what separates a fun and safe hobby from a scare you could have easily avoided.

Step 3: The pour and the trick for a perfect finish

Once mixed, give your resin a breather. Let it rest for a couple of minutes. This short rest allows the most stubborn bubbles to rise and pop on their own. This time is part of the «pot life», or working time, which is the window you have from when you mix until the resin starts to set like a gummy bear.

Now you're ready to pour. Do it slowly and from a slight height. As it falls, the thin stream of resin helps break up even more bubbles. Pure physics!

Left with tiny bubbles on the surface? Don't panic! Grab your kitchen torch or a long-flame lighter and pass it quickly over the surface, without touching the resin. The heat will make the bubbles say "goodbye" instantly. You can repeat this a couple of times during the first 10-15 minutes. Pure magic!

Step 4: Patience, the great virtue of the resin artist

And that's it! You've done your part. Now it's time for chemistry to do its work. Curing is a slow process that depends heavily on the temperature and humidity of your environment.

1. Protect your piece: Cover it with a plastic box or an upside-down food container. Dust is the number one enemy of a glossy finish.
2. Curing time: Arm yourself with patience. Generally, you'll need to wait between 24 and 72 hours for the piece to become rock solid.
3. Demold with care: Once the time has passed, demold your creation. If it feels slightly flexible, don't worry. Leave it on a flat surface for a few more hours until it reaches its final hardness.

Resin has become so popular that there are resources everywhere. Many brands offer detailed guides. If you've caught the bug and want to go deeper, you can check out guides on epoxy resin at lapajarita.es to add more tricks to your arsenal.

Creative techniques for coloring and adding effects to your resin

Alright, we've reached my favorite part. If you thought clear epoxy resin was already incredible, wait until we start adding color and all kinds of wild effects. This is where the blank canvas transforms into a work of art and your creativity is completely unleashed.

Resin on its own is just the starting point. The real party starts when you customize it. And for that, I've got you more than covered!

The best pigments for coloring your epoxy resin

There are so many ways to add color to your resin, and each one will give you a completely different finish. After lots of testing (and the occasional disaster), these are the three types of colorants that should always have a place in your workshop:

• Liquid resin inks: These are my number one choice for achieving translucent and super-vibrant colors, as if you were creating stained glass or colored crystals. They blend beautifully and just a few drops deliver incredible intensity. They're perfect for simulating water or creating jewelry that looks like genuine gemstones.
• Powder pigments (Mica type): If you're all about the shimmer and pearlescent or metallic finishes, mica powders are absolutely amazing. They give your piece a spectacular depth and movement. Ideal for those galaxy-effect coasters or keychains that shift in tone depending on the light.
• Paste pigments: For achieving solid and 100% opaque colors, nothing beats paste. It comes super concentrated, so just a tiny toothpick tip is more than enough. They work great for figurines, chess pieces, or any project where you don't want any transparency at all.

A golden tip: Less is more! As a general rule, try not to add more than 5-6% pigment relative to the total volume of the mixture. If you overdo it, you could interfere with the chemical reaction and end up with a sticky piece that never finishes curing.

Magic in the mold: techniques that will blow your mind

Once you get the hang of color, it's time to level up and play with techniques that will leave everyone speechless. Here are two of my favorites:

1. 'Petri Dish' effect: The technique is simpler than it sounds. Pour a layer of clear resin and, on top of it, drop dots of alcohol inks in different colors. Right after, add a few drops of white alcohol ink. Since white is denser, it will sink and drag the other colors along with it, creating amazing cell-like shapes. It looks like something straight out of a microscope!
2. Creating gradients: For this, prepare several small cups of resin in different colors. Pour the first one into one area of the mold. Then pour the second one right next to it, so they just touch. Using a fine toothpick, gently blend the join between the two so the transition comes out smooth and perfect.

The world of resin crafts is so vast that there's always something new to try. If you're looking for more inspiration, the Feroca guides on what you can make with epoxy resin are a goldmine of ideas.

Creative encapsulations for one-of-a-kind pieces

Encapsulating things is one of the coolest applications of resin. You can immortalize almost any object, but there are a couple of tricks to keep in mind to get it right:

• Flowers and organic elements: The key is that they are completely dry. Any trace of moisture can react with the resin, rot the element, and ruin the entire piece.
• Glitter, gold leaf, and flakes: Add them directly to the resin mix or spread them between layers to create depth. The shimmer is more than guaranteed!
• 3D printed miniatures: My specialty! If you want to embed a resin-printed mini, you first need to seal it with an acrylic varnish. This creates a barrier that prevents the resin from seeping in and forming bubbles or strange stains. If you love painting minis and want to take your finishes to the next level, I highly recommend our article on Vallejo paints for miniature modeling. It's the perfect combo!

The most important thing is that you experiment without fear. Combine colors, textures, and objects. This is where your epoxy resin crafts stop being a simple project and become something personal and spectacular. Let's create!

How to fix the most common mistakes with epoxy resin

Okay, let's be honest. No matter how much we love this world, sometimes things don't turn out like in those Instagram videos. But don't panic, because that's exactly why I created this survival guide: your first aid kit for when resin gets rebellious.

Before we dive in, a mantra I want you to burn into your memory: every mistake is a lesson. I'm telling you this as someone who has messed up more times than I can count. Thanks to those disasters, I can now give you the shortcuts so you don't stumble over the same stones. Let's get into it!

Drama number one: my resin won't cure and it's sticky

This is, without a doubt, the problem that causes the most frustration. You've waited 24 hours with all the excitement in the world, you touch the piece and... horror! Your finger sinks into a soft, sticky mess.

The cause, 99% of the time, is one of these two:

• The mixing ratio was a disaster: I've already told you, but I'll keep saying it until it sinks in: the precision scale is your best friend. One gram too many or too few in the mix and the chemical reaction is gone.
• You didn't mix it enough (or did it wrong): A couple of stirs won't cut it. You need to scrape the sides and bottom of the cup thoroughly, like there's no tomorrow. That way you make sure Part A and Part B fully combine and work their magic.

The solution (if there is one): Fixing a piece that hasn't cured is nearly impossible, but it's worth trying if it's only certain areas. Try cleaning the sticky part with isopropyl alcohol and, once dry, apply a new thin layer of resin — this time, properly mixed. If the entire piece has gone wrong... I'm sorry, but you'll have to start from scratch. Hang in there!

The nightmare of "orange peel" or craters

You demold your creation, expecting to see a mirror-smooth surface, and instead you find small pits or a rough texture. As if your piece had cellulite.

This problem almost always points to the environment. The most common cause is humidity or sudden changes in temperature while the resin is curing. It can also happen if the mold or the surface you're covering had traces of grease, silicone, or dust.

My golden tip: keep your work area at a stable temperature, ideally between 22 °C and 25 °C. An environment that's too cold or too humid is poison for a crystal-clear finish.

My piece looks like a fizzy drink! (microbubbles)

Bubbles are the arch-enemy of a professional, transparent finish. If after using the torch you can still see a cloud of tiny dots, the problem started during mixing.

Most likely you stirred with too much energy, as if you were whipping egg whites for a meringue. That vigorous movement introduces thousands of air microbubbles into the resin that are then almost impossible to remove.

The solution: Next time, take your time. Mix slowly, with gentle and controlled movements. Once you pour the resin into the mold, in addition to using a torch or a lighter, you can give the sides of the mold some gentle taps. This helps the most stubborn bubbles rise and escape. Patience and delicacy are the key to success!

Think of this section as your cheat sheet so that no setback holds you back. In the end, every small mistake brings you one step closer to creating that perfect piece you have in mind.

Frequently asked questions about epoxy resin for crafts

The time has come to answer those questions that keep you up at night. Here I bring you the million-dollar questions I receive almost daily about epoxy resin for crafts. Straight answers, no beating around the bush, so that nothing stands between you and your next masterpiece.

Why has my resin piece turned out flexible?

Ah, the drama of soft resin! If after patiently waiting 24 hours your creation bends like a gummy candy, it's almost certain that one of these two things happened:

• The mixing ratio got out of hand. This is, without a doubt, the most common beginner (and not-so-beginner) mistake. A single gram too many or too few can ruin the chemical reaction, and the result is a piece that never fully hardens.
• You didn't mix like there was no tomorrow. You need to scrape the sides and bottom of the cup thoroughly, making sure every drop of resin and hardener get intimately acquainted. Lazy mixing is a guaranteed recipe for failure.

Another cause may be that the environment was colder than your ex's heart. Resin needs warmth to cure properly. My golden tip: use a precision scale, mix calmly but thoroughly, and keep your piece in a warm place.

How do you clean resin tools?

For liquid residue, the trick is to act fast. Grab some paper towel, soak it in isopropyl alcohol, and clean everything before the resin starts to harden. And whatever you do, never, ever pour liquid resin residue down the drain! You will contaminate a huge amount of water.

Although, if you want a life-changing tip, invest in silicone cups and stir sticks. Simply let any leftover resin dry completely. The next day, it will peel off in one piece, effortlessly. And your tools will be ready for another creative battle!

Is epoxy resin safe for food contact?

Pay close attention here, because this is serious! The short answer is: no, not all of them are. If you have in mind creating coasters, trays, or any object that will have direct contact with food, you need a resin that is specifically certified as 'food safe' or "suitable for food use."

Don't take anything for granted. The manufacturer must indicate this clearly and visibly on the label or in the product's technical data sheet. If it doesn't say so, assume it is not safe. Don't risk it!

Conclusion:

And there you have it, maker! You've just devoured a complete guide to mastering epoxy resin for crafts. In my experience, the key is to dive in fearlessly, respect safety as if your life depends on it and, above all, enjoy the process. Mistakes will happen, but they're the best teacher!

I hope I've sparked your curiosity. Now you have all the tools and tricks to start creating pieces that leave everyone speechless. From unique jewellery to jaw-dropping dioramas. So, let's get to work and bring those ideas in your head to life!
