Art resin

If you’re a resin crafter, chances are you’ve heard about “castable” or casting resins. But did you know that art resin can also be used for casting? 

Art resin, also known as epoxy resin, is an ideal solution for casting projects. However, it’s relevant for small-scale projects. Further, for every 1/8 inch thickness of resin, a curing time of 72 hours is recommended.

In this blog post, we will discuss the differences between “casting” and “art” resins, as well as some of their pros and cons for crafting purposes. We’ll explore when it’s appropriate to use each type of product—whether creating detailed blocks of beautiful embeds or cleanly molding an entire object—in order to help make sure you select the right product for your project. So let’s get to it!

Art resin for casting

Art Resin For Casting

Art resin is a two-part resin mixed together with a hardener before it can be poured into a mold and left to cure. This low-viscosity formula makes it perfect for creating finely detailed pieces as well as larger sculptures and objects. Including glass objects.

The primary benefit of using art resin for casting is its resistance to yellowing and UV light. This makes it suitable even for outdoors artwork that will be exposed to the elements. Not only will the finished product retain its color, but it will also stay strong and stable in even the harshest environment.

When working with art resin, it’s important to follow the manufacturer’s instructions precisely in order to ensure that your project turns out correctly.

The mixing ratios and curing times can vary depending on the type of product being used, so make sure you’re aware of these details before beginning your project. Additionally, make sure you work in a well-ventilated area because fumes from the resin can be dangerous if inhaled in large quantities. 

How Thick Can You Pour Casting Resin

Most casting resins have a pourability that allows for a single layer of up to 1/8 inch to 1/4 inch thickness. It also depends on the specific type of resin being used, the type of mold, and manufacturer’s instructions.

If you desire thicker layers, then it’s necessary to pour multiple layers, allowing each one to fully cure before pouring the next. In order to achieve an optimal result, it is important to follow the manufacturer’s instructions regarding pouring thickness, as this will vary from brand to brand and even from product to product.

Additionally, the type of mold being used can also influence the maximum pourable thickness, curing time, and strength of the finished product. It is important that each layer is correctly cured before adding more layers; otherwise, there could be issues with weak areas or inaccurate final pieces.

Note: Pouring casting resin too thick can increase drying time and may lead to finished products that are not as strong or detailed as desired.

Art resin vs. casting resin

Art resin is viscous, has longer curing times, and is preferred for art-based projects due to its glossy finish while casting resin is thinner and recommended for creating molds. They differ in their purposes, although they belong to epoxy resin types.


Art resin is popular among many DIYers and crafters because it’s easy to use, cures quickly, and produces a glossy finish. Designed specifically for coating acrylic paintings or other artwork, it’s low odor, non-flammable, and offers UV protection from yellowing.

On the other hand, casting resin is much thicker than art resin and generally used for creating numerous parts by filling molds – such as jewelry, furniture pieces, or sculptures. 

To ensure a perfect end result with your casting project, be sure to select the exact grade of resin that fits your specific needs best.


Art resin is typically thicker and more viscous than casting resin, which makes it easier to work with and better suited for coating surfaces or creating a glossy finish. 

Casting resin, on the other hand, is generally thinner and more fluid in comparison; this allows it to be poured into molds more easily and enables more precise shapes and details to be created.

Curing time

In terms of curing time, art resin usually takes longer than casting resin for it to become fully hardened – this can be beneficial for those who need extra working time with the material but may prove inconvenient if you’re looking for a quick turnaround.


Finally, art resin is mainly used in artistic endeavors such as paintings, sculptures, or jewelry making, whereas casting resin is typically used for objects like molds. 

Regardless of the different properties of these two resins, both types play an important role in creative applications when used correctly. 

Art resin can offer superior surface finishes as well as depth in works of art while casting resin provides excellent structural strength and precise details required for objects like models or jewelry components. 

Taking all these factors into account will ensure that you make the right choice depending on the project at hand.

Final Thoughts

Art resin is different from casting resin and shouldn’t be used for the same purpose. While both resins come with their own set of pros and cons, it’s important to understand the difference between the two before beginning your project. 

With the proper knowledge and understanding of art resin, you can create beautiful works of art that will last a lifetime.
