Difference Between High and Medium Viscosity Epoxy

Understanding Viscosity in Epoxy Resins

Viscosity refers to how thick or fluid a resin is when poured. High viscosity gel epoxies are much thicker—they flow slowly, allowing you to work with more precise control. Medium viscosity resins, on the other hand, spread more easily and are somewhat thinner, making them well-suited for even coatings and general craft applications.

Choosing Between High and Medium Viscosity

• High viscosity: Ideal for applications where you want to minimise spreading or bleeding of colours, such as in detailed resin art, geode designs, or layered effects. Resin like Art Pro Deluxe grants strong line control and lets you work on intricate designs without colours mixing undesirably.
• Medium viscosity: Suits broader surface coatings, coasters, and decorative crafts where you need a smooth, self-levelling finish. Products like “Art Pro” or “One-2-One” simplify the process, as the resin moves more freely and levels itself easily across surfaces.

When Viscosity Matters Most

Precision artwork, layered pours, or projects requiring crisp edges benefit from high viscosity resins. For functional coatings or simple casting, a medium viscosity resin can speed up application and give a seamless result. If you’re new to resin, starting with medium viscosity can be less intimidating and easier to handle.
