Resin Curing Troubleshooting Guide

Resin Curing Troubleshooting Guide

One of the most important processes of resin art and craft is curing. When your epoxy does not cure as it should, then you may end up with a sticky surface, cloudy, or even wasted materials. There is nothing to fret about--all resin artists have curing concerns at some stage. This tutorial will take you through the most usual resin drying issues, the reasons behind them and the solutions to the issues when dealing with epoxy resin products.

Why Curing Matters

Epoxy resin is hardened during a chemical reaction experience between the resin and hardener. Without the right balance in the mixture or the right environment, the treatment is not complete. Correct curing makes your resin creations crystal clear, tough and durable.

Typical Resin Curing Problems & Solutions

1. Sticky or Tacky Resin:

Cause:

• Wrong proportion of resin to hardener.
• Under-mixing
• Low room temperature

Solution:

• Never weigh resin or hardener, but always by volume (or weight, where indicated).
• Stir at least 3-5 minutes, scrape sides and bottom.
• Continue curing at 21-25 degree C.

2. Soft or Flexible Resin:

Cause:

• Lack of hardener in the mix.
• Short curing time.

Solution:

• Cheque total ratios- Res-iT resins are formulated to cure in a ratio of 2:1 (cheque product instructions).
• Freeze (24 -72 hours depending on thickness).
• In the case of soft projects, re-pour a layer of thin material with the right measurements.

3. Cloudy or Milky Finish:

Cause:

• Environmental dampness or moisture.
• Too rapid of mixing (air bubbles)
• Pouring in a damp space

Solution:

• Work in a dry, dust-free room.
• Stir not to whip up air.
• Heat a heat gun or torch gently on the surface in order to get bubbles out.

4. Resin Didn't Cure at All:

Cause:

• Inappropriate proportions (excess of resin and lack of hardener)
• Using expired products
• Temperature too cold

Solution:

• Expire before cheque is used.
• Always measure precisely.
• Make your area warm to cure.

5. Yellowing Over Time:

Cause:

• Natural UV exposure
• Using low-quality resin

Solution:

• Use only UV-resistant epoxy resin (such as the Res-iT range).
• Keep finished resin products out of the light.
• Use a UV protective top coating over outdoor resin art.

6. Uneven Curing in Thick Pours:

Cause:

• Pouring resin, too thick at a time.
• Exothermic reaction (heat build-up)

Solution:

• In deeper moulds or tables, add layers of 1 -2 cm at a time.
• Pour layers on top of each other and this will be partially allowed to dry.

Pro Tips for Flawless Curing:

• Never miss the instructions on your Res-iT Epoxy Resin Starter Kit.
• Heat pre-warm bottles in warm water bath in case your working area is cold.
• Stay out of the direct airflow of fans or heaters -this may bring in dust.
• Cure your project under cover to avoid debris.
