How to Select Epoxy Resin by Project Size & Thickness

← Back to What can you do with two-component resin?

When planning your next resin project, selecting the correct epoxy resin based on both project size and desired casting thickness is essential for a successful result. Follow this guide to make the right choice every time.

Choosing the Right Resin for Thin Projects (Up to 2cm)

For smaller items, detailed mouldings, jewellery, and surface coatings where the resin layer will be up to 2cm thick, a clear multipurpose epoxy such as Trasparente is the go-to. Its ultra-clear finish and reliable self-levelling properties make it ideal for beginners and professionals alike. Using the correct thickness prevents overheating and ensures flawless results, especially in smaller moulds or flat castings.

Deep and Ultra-Deep Pours: 2–5cm and Up to 10cm

Bigger pieces and tabletops often require pouring resin in thicker layers. For pours between 2cm and 5cm, such as medium-sized rivers or tabletops, EpoxyTable 5-Five is optimised to cure safely with minimal bubbles. When working on grander projects, like extra-large slabs or sculptures requiring a single layer up to 10cm, Epoxytable 10-Ten handles the job with a slow reaction that prevents overheating even on the largest pours. Remember, for any casting over 10cm or with extraordinary dimensions, it’s wise to pour in multiple layers for safety.

When This Matters Most

Complex handmade items or resin artwork where clarity and detail are vital
Tabletops or countertops requiring thick, durable layers
Large-scale casting projects – where the right resin avoids cracks or improper curing
