How do you mix resin for beginners?

Resin is a polymeric liquid that hardens when cured. It’s commonly used for jewelry making, sculpture and other arts and crafts projects.

In this article, we’ll show you the process of mixing resin for beginners. You’ll learn how to mix resin properly so that your pieces don’t bubble or crack. We’ll also discuss what tools you’ll need to do it.

What is the ratio of resin to hardener?

Mixing resin and hardener is easy and seems pretty straightforward, right? Well, yes and no.

You’ve probably heard that a resin-to-hardener ratio of 1:1 is best for most projects. This can be true for some projects but not all—it really depends on what kind of project you are making and what kind of results you want from your finished piece.

For example, if you are making a small bottle with just one layer of glass in the bottom half (like I did), then using a ratio that is higher in hardener than resin may produce better results because it will fill any bubbles quickly without making them crack as much when they cool down again.

How do you mix resins?

Use safety glasses and gloves when working with resin.

  • Wear safety glasses to protect your eyes from accidental splatters and dust. You’ll also want to wear a mask, if possible, to keep dust out of your lungs as well.
  • Wear plastic-coated disposable gloves while working with epoxy and polyester resins because they can irritate the skin of some people who come in contact with them.

You will need two different cups (one for each part) and a disposable stir stick or spoon to mix the two parts together before pouring it into the mold you’ve chosen.

What is the ratio for resin?

To mix resin, you need a hardener. The ratio of resin to hardener is always 2:1. If you’re using a smaller amount of hardener than that, it’s best to use a 1:1 ratio instead of adding more material because this will create bubbles in your project and make it more difficult for them to cure properly.

When mixing resin on its own (without any other additives), the ratio is 1 part resin per 1 part hardener—that’s the standard mixture for most resins out there.

However, if you want better adhesion between layers or if your project requires different curing times than what would be achieved through just mixing them together (for example, if one layer takes longer than another), then there are modifications that can be made:

  • Using an accelerator instead of plain water alone will increase both curing speed and strength of bonds between layers; however, this will also reduce flexibility in projects like jewelry or figures with lots of movement happening within multiple planes at once where they need to bend while still remaining rigid enough not break off easily under stress caused by the movement made during activities like walking around etcetera so take care when using accelerators since although they help speed up process time considerably when used correctly
  • Adding thinner sprays throughout the process allows greater control over how fast everything dries while allowing easy access into tight areas without having too much pressure applied which might cause damage such as cracking parts

What do I need for beginner resin?

You’ll need:

  • mixing cups. These come in a variety of shapes and sizes, but the most common are cylindrical. They should be durable and heat resistant, so you don’t end up burning your glass in the process.
  • Mixing sticks to stir your resin with. You can use popsicle sticks, chopsticks, or any other kind of stick that works for you. The resin will adhere to them while they mix with it, so these are a helpful tool when working with resins that have an odor or smell like food or spices (like cinnamon).
  • Disposable gloves if you want to wear them while working with resin; they help keep your hands safe from exposure by keeping them away from any possible spills or splashes during the mixing process! You’ll also want protective clothing on as well—a long-sleeved shirt is best because it offers more protection over bare skin than shorts would provide without having to worry about getting messy later down line either way! If needed paper towels may also serve well here as well depending on how much space it is available around where we’ll be working together 🙂
  • If necessary: Hairdryer – Heat Gun

How long should I mix resin?

It’s important that you mix your resin properly.

Resin should be mixed for at least 2 minutes, preferably 3.

This will ensure that the resin is completely dissolved and that there are no lumps or air bubbles left in it.

Where do you mix resin?

When it comes to mixing your resin, there are a few things you need to keep in mind. Your mixing surface should be smooth and non-porous. This way, the resin will stick well to the surface and not move around too much when you’re adding drops of catalyst.

Popsicle sticks are great for this because they’re cheap, disposable, and easy to clean up after using them. If you don’t have popsicle sticks handy, any other piece of wood that’s smooth would work – just make sure that it isn’t porous (wood can absorb liquids).

Avoid using paper cups for this purpose – they’re not as sturdy as plastic or metal containers and might end up tearing after repeated use with epoxy glue! If you do choose to mix your resin in a paper cup though it’s important that the cup has been thoroughly cleaned beforehand so there isn’t any dirt left behind from previous uses (which could cause contamination).

As far as what type of container goes into my kit? It depends on how much space I have available: Metal cups are best suited if I’m going somewhere outside where glass may break easily during transport; meanwhile plastic cups tend to work better if I want something less fragile but still durable enough so nothing spills over onto my clothes or skin!

What should resin look like when mixed?

Once you’ve added your ingredients and mixed them together, the resin should look like clear water with no lumps or bubbles.

If your resin has a white film on it or contains lumps or bubbles, then it means that your mixture was not thoroughly mixed.

Your resin should also have the same color throughout—if there are sections of different colors, then this is an indication that some parts of your mixture were not properly mixed together.

The good news is that you can still use this type of defective resin! You just need to be careful when curing it so that those areas aren’t exposed to direct UV light.

How do you mix 3 resin?

You will need:

  • The appropriate amount of resin and hardener for your project. For example, if you were mixing 1 batch of resin, you would use equal parts by weight or volume. If you were making 2 batches of resin at once, then each batch should be half the amount needed (since there are 2 components).
  • Two separate containers to measure the materials into. These can be disposable cups or plastic cups from the kitchen—whatever works best for your situation. Try not to mix up the measurements between them!
  • A stir stick or something similar for mixing together both components thoroughly before pouring into another container.


  • Always wear gloves and protective eyewear when handling resin.
  • Always measure resin and hardener by volume, not weight.
  • Mix the two components thoroughly before using them.
  • Pour the resin mixture into a fresh disposable cup before using it for your project, so you can keep track of what’s been used and how much is left.
