It can be frustrating when your resin pour doesn’t set as expected, leaving you with a sticky or soft finish. Here’s how to troubleshoot and recover from this common issue to achieve a successful DIY project.
Common Causes of Resin Not Curing
The main reason resin stays tacky or soft is improper mixing or an inaccurate resin-to-hardener ratio. Epoxy resins are sensitive to small measurement errors, so even a slight miscalculation can prevent full curing. Always check the manufacturer’s instructions for the correct ratio and double-check your measuring tools before starting a pour.
Fixing and Preventing Sticky Resin
- Double-check your process: Review how you mixed the resin and hardener. If you spot any skips in the instructions or realise the mixture was not fully combined, you’ve likely found the culprit.
- Mix thoroughly: Take at least 3-5 minutes to blend the two parts, scraping the sides and bottom of your container for even consistency.
- Post-pour options: Minor stickiness on the surface can sometimes be removed by carefully scraping and re-coating with fresh, properly mixed resin.
- Future prevention: For reliable results, consider kits designed for beginners, such as the “River-Table” Complete Kit, which includes detailed instructions and accurately measured components.
When This Matters Most
Proper curing is essential if you’re making furniture, jewellery, or art pieces, as a sticky surface can pick up dust or lose its visual appeal. Carefully following instructions is key for both beginners and experienced makers.
