How do you pour clear resin?

There are a couple of different kinds of resin that you can use to make clear castings.

The main difference between casting resins is the type of catalyst they use.

The most common types of casting resins are clear epoxy casting resin, clear polyester casting resin, and polyurethane casting resin. The differences between these three types of resins are important as they will determine what you can do with your finished product.

How do you get perfectly clear resin?

If you have a casting that is cloudy and you’re thinking to yourself, “How do I get perfectly clear resin?” then you’ve come to the right place. There are many factors that affect clarity.

Temperature: In order for resin to cure to a transparent state, it needs to reach the proper temperature. The temperature should be around 75 degrees F (or 24 C) for ideal curing conditions.

Most users report seeing their best results in this range, but we recommend checking the manufacturer’s recommendations if your room is much colder or hotter than this—and remember that resin sets at slightly different speeds in different temperatures, so it’s important for your epoxy casting resin to stay at a consistent tempo when it’s curing.

How do you pour clear epoxy resin?

  • Pour the resin slowly onto the surface where you want it to set. As you pour, try to do so in one smooth, even motion and in a way that lets the resin spread out across your surface. If your surface is wide enough or if your resin project requires several pours of resin (like a river table), pour the resin in sections rather than all at once. This will make it much easier for you to prevent bubbles from forming or rising to the top of the project by allowing them time to dissipate while they’re still at least somewhat liquid.
  • Pour each layer of resin slowly and smoothly onto the previous layer of cured/dry resin rather than directly onto any other surface (i.e., wood). To make this process as easy as possible, pour/brush on multiple thin layers rather than one thick layer at a time; this will enable better light refraction when your project is complete.

How do you cast clear resin?

Step 1: Mix the resin in a cup.

Step 2: Pour into a mold, and let it cure for 24 hours.

Step 3: Sand edges with sandpaper.

How do you pour resin at home?

Resin casting is a fun, versatile activity that any crafter can enjoy. Before you start, you will need to gather all the tools and materials you need for your project. There are also a few safety precautions involved in working with resin.

Needed tools:

  • A scale that measures in grams to weigh out your resin components. If you don’t have one, you can use a liquid measuring cup instead.
  • Mix cups and stir sticks (or an electric mixer) for preparing your resin mixture.
  • A pouring container of some kind for mixing larger amounts of resin or containing overflow during the curing process.
  • Desiccant packs absorb moisture from the air that may otherwise get trapped in your final piece when casting with clear resin.
  • Any objects that you want to embed into your finished piece (pictures, flowers/leaves, etc.). If using pictures or other flat items in place of mold releases such as PVA glue, wax paper, or parchment paper (optional but recommended).
  • Gloves and protective eyewear are always a good idea! You never know when things might splash or splash around while pouring uncured resin.

How do beginners use resin?

Resin can be used for many things, and you may have even seen it on the shelves in a hardware store. Unsurprisingly, many first-time resin users wonder “how do you pour clear resin?”

Whether you’re a beginner or an expert, it is important to understand all aspects of the resin casting process.

This includes knowing what supplies are needed and how to mix your resin with any dyes or add-ins like glitter.

On top of that, you should be aware of what ratios to use and how long to let your project cure before handling it.

And if you want a professional finish, there are some details about sanding and polishing that will help your project look amazing!

What happens if you pour resin too deep?

Pouring resin too deep is dangerous and can cause the resin to get hot. If you pour it less than 1/8 of an inch thick, the resin may not cure.

Because UV resin cures with heat, if you pour more than 60 millimeters (2.4 inches) thick, the curing process will result in a part of the resin getting very hot (up to 200°F is possible), which may bubble or distort your mold, especially if it’s made of silicone.

If there is no reaction like bubbling or foaming and your project looks just fine after 24 hours, then it could be cured enough for handling.

However, if there are bubbles or other indications that the curing process has not been completed yet — please wait another day or two for a full cure before taking the piece out of its mold.

How do you pour epoxy resin without bubbles?

Pouring slowly and using a heat gun to remove bubbles is only one part of the process. If you pour too fast or pour in a thick layer it’ll cause more bubbling than necessary.

You can also try pouring in layers to release those bubbles and then add another layer before they have time to settle back down into your resin.

Here’s an example video from our YouTube channel where I demonstrate this method of getting rid of bubbles by pouring in layers.

Finally, if you’re still experiencing lots of bubbling, you may want to try adding a little bit less hardener than the manufacturer recommends.

When adding less hardener (don’t go much lower than 2% less) you’ll need to be extra careful with your temperature because the mixture will cure faster with less hardener making it difficult to work with if it’s too hot!


The best way to avoid bubbles is to mix the resin slowly and deliberately. The fastest way to get air bubbles in your resin is by mixing it too fast.

Take your time and pour in a thin, slow stream from one container into another. If you have more than one person helping, they can take turns pouring while you mix.

By taking these steps with your first pour, you’ll minimize the chance of having any problems! Once you have practiced and perfected your technique, it’s best to use an open space like a garage or workshop when casting resin as the fumes can be hazardous if inhaled over an extended period of time.
