What to Do If Coloured Resin Remains Sticky

← Back to How do you colour epoxy resin for painting?

Encountering sticky coloured resin can be frustrating, whether you’re experimenting with painting techniques or working on a detailed epoxy art piece. Fortunately, there are straightforward steps you can take to diagnose and resolve this issue so your resin project looks and feels exactly right.

Common Causes of Sticky Resin

Sticky resin surfaces are usually the result of an incorrect mix ratio between the resin and hardener, or from adding too much pigment to your mixture. It’s important to follow product-specific guidelines carefully—excessive colourant can prevent proper curing, while a mismeasured hardener may leave your resin soft or tacky. Always measure both components accurately and avoid exceeding pigment recommendations, such as the guidance for the Colourfun Set, to achieve thorough curing.

How to Fix Sticky Coloured Resin

If a patch of your coloured resin remains sticky after curing, first try to carefully remove the tacky layer using a scraper or cloth. Once the residue is cleared, you can re-coat the area with a fresh, well-measured batch of resin, making sure to respect the correct resin-to-hardener ratio and use pigments sparingly. This approach ensures your final surface becomes smooth and fully set. Allow adequate curing time in a dust-free environment for optimum results.

Preventing Sticky Resin in Future Projects

To avoid sticky outcomes, always use high-quality colourants intended for epoxy resin painting, like the Colourfun Liquid Colourant. Carefully mix your resin and hardener following manufacturer ratios, and only add as much pigment as advised. Proper preparation and attention to details during mixing significantly reduce the likelihood of sticky surfaces and help achieve professional-looking finishes.

When This Matters

This troubleshooting is crucial for artists and crafters aiming for smooth, flawless finishes in projects like coasters, jewellery, or artwork. Resolving stickiness helps maintain both aesthetics and functionality of resin creations.
