What is the Difference Between Casting and Coating Resins for Coverage?

Understanding Coverage: Casting vs Coating Resins

Casting resins are formulated for deep pours, typically allowing you to create layers up to 1.5–2cm thick in a single application. This makes them ideal for projects like river tables, deep art pieces, or embedding objects within the resin. In contrast, coating resins are designed for much thinner layers — usually ranging from just 1mm up to 10mm per application. They’re perfect for achieving smooth, glass-like finishes on artworks, table tops, and decorative objects.

• Casting resin: Best for deep applications up to 2cm per layer
• Coating resin: Optimised for finer surface coats between 1–10mm

Selecting the Right Resin for Your Project

Choosing the right resin is largely determined by your intended layer thickness and the type of finish required. For deep pours, a dedicated casting resin such as “Trasparente” Multipurpose Epoxy Resin ensures clarity without rapid overheating. For protective or artistic surfaces, a specialised coating resin like Art Pro offers superb gloss and scratch resistance at thinner thicknesses.

When This Matters Most

The distinction between casting and coating resins is especially important when layering or encapsulating items. Using the wrong resin for the application may result in bubbling, poor curing, or even surface imperfections. For tables with embedded features, always opt for casting resin. For art and surface protection, stick with a quality coating resin to prevent excess build-up.
