Why Is My Resin Painting Sticky After 24 Hours?

Coming back to your resin painting after a day, only to find it sticky or soft, can be frustrating. If your artwork remains tacky after 24 hours, there are a few common causes—and fortunately, some straightforward solutions.

Common Causes of Sticky Resin Surfaces

The most frequent culprit for sticky or soft resin is incorrect measuring or incomplete mixing. Resin is made from two parts that must be combined at the right ratio—if this isn’t measured properly or if the mixture isn’t fully blended, it can stay tacky even after the expected curing time. Always follow your resin kit’s instructions and mix slowly but thoroughly, scraping sides and bottom of your mixing container to ensure a seamless blend.

How to Avoid Tacky Resin Paintings

Use clean, precise measuring tools for both resin and hardener, and double-check your ratio. For example, the “Raphael Kit” – Pour Paint & Resin Art Set uses a 3:2 ratio; even small errors here can impact curing. Stir the mixture for the recommended time (usually several minutes) and don’t rush—patience is the key to an even, durable finish.

When This Matters Most

Sticky resin is especially problematic when working on layered artwork or if you plan to add additional paint or resin details. A soft surface will not support subsequent pours and can collect dust or fingerprints. For best results, wait until the cured surface is hard and non-tacky before moving forward.
