Are you wondering what you can do if your UV resin is still sticky or soft even after curing?

To properly cure sticky UV resin, follow these steps and tips. Stickiness usually happens due to under-curing, incorrect resin mix, or contamination.

✅ Fixing Sticky UV Resin

If your resin is sticky or soft after curing, here’s what you can do to fix it:

1. Expose to more UV light
   • Place it under a UV lamp (36W or higher) for 2–10 more minutes.
     Repeat 2-3 times before accepting its a loss.
   • Or place in direct sunlight for 15–60 minutes.
   • Make sure the light hits all surfaces evenly.
   • Cure both on the front, back and sides of your piece.
     
2. Place your piece in water and cure
   • Place your piece in a glass of water (room temperature).
   • Hold your UV light or torch through the glass and on to your piece for 3 minutes.
   • Take your piece out of the water and let air dry (in case it is not cured)
     
3. Wipe the surface with isopropyl alcohol (IPA)
   • Sometimes the stickiness is just the oxygen-inhibited layer.
   • After trying the above, use a lint-free cloth and 91%+ IPA to gently wipe it.
     
4. Apply another thin layer of resin and cure again
   • A thin topcoat can seal tacky surfaces. Cure thoroughly afterward.
     
5. Remove and redo (last resort)
   • If it stays gooey, scrape off the bad resin and re-pour with a new, well-mixed batch.

🧪 Prevention Tips for Next Time

• ✅ Cure under a strong UV lamp (36W+ is ideal)
• ✅ Apply thin layers (under 3 mm at a time)
• ✅ Make sure the resin is fresh (check expiration)
• ✅ Avoid humidity and cold temperatures while curing
• ✅ Avoid using dark colours or too much pigment
