It can be frustrating when your resin stays sticky, soft, or won’t set as expected. Let’s explore the common reasons behind incomplete resin curing and how to fix them for a flawless finish.
Common Causes of Sticky or Soft Resin
Most curing issues stem from the crucial mix between resin and hardener. Inaccurate measurements—either too much or too little hardener—can prevent chemical reactions from completing. Inadequate mixing can also leave parts of your project uncured. Always measure resin and hardener according to your product’s instructions, using accurate tools for best results.
Practical Solutions and Prevention
- Double-check ratios: Use digital scales or marked mixing cups to avoid mis-measuring.
- Mix thoroughly: Scrape the sides and bottom of your mixing container for a uniform blend.
- Observe correct conditions: Work at the recommended temperature and avoid using expired products.
If you need extra precision or want a reliable finish, consider a quality epoxy like Art Pro Deluxe, which offers clear instructions and consistent curing.
When This Matters Most
Sticky or soft resin poses bigger problems in functional items such as coasters, trays, or jewellery. Incomplete cure can mean your project is unusable or needs to be redone, costing both time and materials.
