Every resin crafter hits a few frustrating issues early on. The good news? Most have simple causes and easy fixes. Here's a troubleshooting guide to the most common problems.
1. Tacky or Sticky Resin
The cause: incorrect resin-to-hardener ratio or under-mixing.
The fix: measure precisely and stir thoroughly (scraping the sides and bottom) for the full recommended time.
2. Bubbles
The cause: fast stirring or pouring, or cold resin.
The fix: stir slowly, warm the resin slightly before use, and gently pass a heat source over the surface to release bubbles after pouring.
3. Yellowing
The cause: low-quality resin or UV exposure.
The fix: use a quality, non-yellowing (UV-resistant) resin and keep finished pieces out of harsh direct sunlight.
4. Soft Spots or Uneven Curing
The cause: uneven mixing or pouring too thick in one go.
The fix: mix well and pour in layers if your project is deep, letting each layer cure.
5. Dents, Dust or Debris
The cause: an unclean or dusty environment.
The fix: work in a dust-free space and cover your piece while it cures.
6. Resin Won't Release From the Mould
The cause: incomplete cure or a low-quality mould.
The fix: wait for the full cure time and use quality silicone moulds that flex easily.
Golden Rules
- Measure precisely, every time.
- Stir slowly and thoroughly.
- Be patient with the cure.
