Using the Same Resin for Art and Casting – Is It Possible?

Not all resins are made equal—especially when it comes to the difference between artwork and casting. Understanding which resin to use can be the key to a flawless finish and a successful project, whether you’re coating a canvas or pouring a thick mould.

Understanding Resin Types and Project Needs

Resins designed for art projects, such as glossy coatings or painted surfaces, are generally formulated to be applied in thin layers. These ‘art resins’ cure to a clear, hard, high-gloss finish, making them ideal for surface treatments, coasters, and decorative trays. In contrast, ‘casting resins’ are made to handle deeper pours, typically in moulds, where a thicker mass is required—think jewellery pieces or large river tables.

Using an art resin for a thick casting can lead to overheating, excessive bubbles, or an incomplete cure. Conversely, casting resin poured in a thin coat may cure too slowly or finish with a duller surface than desired.

Multipurpose and Layered Solutions

If your projects require both beautiful surface finishes and some light casting, a multipurpose resin—like Trasparente—may be suitable. These resins balance self-levelling and clarity with a pour depth typically up to 2cm. Deep castings, such as tables or blocks over 2cm thickness, are best tackled with specialist deep-pour resins like EpoxyTable 5-Five, which are carefully engineered to keep heat build-up under control in thick layers.

For thick art projects or embedded objects, choose a resin specifically labelled for deep casting.
For surface art or shallow coatings, opt for a high-gloss art resin with good self-levelling properties.
Always check the manufacturer’s guidelines regarding maximum pour depth and recommended uses.

When Does This Matter?

The decision matters most when your project goes beyond simple surface work or involves mixed techniques, such as embedding found objects beneath a clear surface. Using the wrong resin can mean a failed cure, trapped bubbles, or a less-than-glossy finish. For example, using Art Pro resin is best reserved for coatings up to 10mm, while larger castings will call for casting-specific products.
