Curing Problems
- Why did my resin cure with bubbles?
Bubbles in cured resin usually come from trapped air introduced during mixing or pouring. They can also form if the resin is too cold or if you pour too quickly. - How can I fix resin that didn't cure properly?
If resin is still sticky or soft after the full cure time, you can sometimes apply a new top coat of properly mixed resin. If it's a complete failure, you may need to remove and repour. - What causes resin to cure cloudy?
Cloudy resin is typically caused by moisture, cold temperatures, or improper mixing ratios. It can also result from sanding without polishing to full clarity. - Can I speed up the curing process?
Yes, you can speed up resin curing by warming the room and resin, but avoid excessive heat. UV resin cures faster with a stronger UV light. - Why does my UV resin cure unevenly?
Uneven curing usually happens because UV light can't reach all areas equally, or because the resin layer is too thick. Thinner layers and a strong, close light source help. - Is it normal for resin to shrink while curing?
Yes, some shrinkage is normal for both epoxy and UV resin. Epoxy typically shrinks 1-3% and UV resin can shrink 5-10%, but proper mixing and pouring can minimize issues.
