Why Is My Resin Pendant Sticky After Curing?

← Back to How to make pendants with epoxy resin

A sticky pendant after curing can be one of the most discouraging results when working with epoxy resin. Fortunately, there are some clear reasons behind this issue and practical steps you can take to ensure flawless, glass-like finishes for your resin jewellery.

Common Causes of Sticky Resin Pendants

The most frequent culprit behind sticky or tacky resin pendants is using an incorrect ratio of resin to hardener or not mixing the components thoroughly. Epoxy resin relies on a specific balance—if the proportions are even slightly off, or the mixture is uneven, the chemical curing process will falter, leaving your piece soft or sticky rather than fully set.

Double-check your measurements according to product instructions
Mix slowly but thoroughly, scraping the sides and bottom of your mixing cup
Take your time—rushing mixing can leave unmixed portions, leading to stickiness

How to Avoid and Fix Sticky Resin

Prevention is key: Always use accurate measuring tools and follow a simple, foolproof formula whenever possible. Kits such as our “Evershine Collection” Epoxy Resin Kit use a 1:1 mixing ratio to help minimise errors, making them especially good for beginners. If a pendant comes out sticky, you may be able to salvage it by gently wiping the surface with isopropyl alcohol (if only slightly tacky) or applying a fresh, properly mixed resin topcoat once fully dry.

When Sticky Curing Matters Most

Stickiness can compromise clarity, durability, and the look of inclusions like dried flowers or photographs. For projects where details and transparency are vital—such as personalised pendants or gifts—a resin that cures cleanly is crucial to showcase your artwork and protect the embedded items.
