Resin Stays Sticky or Soft? Steps to Fix Common Curing Issues

Q: Practical Steps to Correct Stickiness

Allow extra time: Give your project at least another 24-48 hours in a warm, dust-free area to see if it further hardens. Check the mixing ratio: Always follow the manufacturer’s instructions closely, especially for products like River-Table kits with specific weight percentages. Minimise disturbance: During the early stages of curing, avoid moving or touching your resin piece, as this can affect the final result.

It can be frustrating to discover your resin project hasn’t cured as expected, leaving a sticky or soft finish. Fortunately, most issues have straightforward solutions.

Assessing Why Resin Remains Soft or Sticky

There are several common reasons for incomplete curing. Firstly, check if the project simply needs more time—some deep pour resins like EpoxyTable 5-Five may take up to 72 hours or longer to fully set, especially in thicker layers or cooler temperatures. If extra curing time doesn’t help, revisit your mixing method. An incorrect ratio of resin to hardener, or insufficient mixing, is often the root cause.

When This Matters Most

Addressing sticky or soft resin is especially crucial if you’re producing tabletops or pieces intended for regular use. Imperfect hardness can affect both durability and the look of your finished table. Investing in a resin formulated for deep pours, such as “Epoxytable 10-Ten”, also helps reduce curing issues on larger or thicker projects.
