What Thickness Can Icrystal Resin Cure Per Application?

← Back to What Is the Resin for Sinks Called?

When working with clear epoxy like Icrystal, understanding the optimal layer thickness ensures a flawless, professional finish. Too thick a pour can cause curing issues, while too thin may not achieve the surface clarity you desire.

Recommended Pour Thickness

Icrystal epoxy resin is formulated to cure best in applications up to 1.5cm (15mm) thick per layer. Staying within this range allows the resin to cure evenly, maximising transparency and strength without risk of excess heat or cloudy finishes. If you need a thicker coating or a deeper feature, it’s best to pour in stages, ensuring each layer has fully set before applying the next.

Practical Tips for Layering

Measure your resin and hardener carefully according to the specified 2:1 ratio for optimal results.
Allow each 1.5cm layer to cure completely before adding another to maintain clarity and prevent warping.
Ideal for table coatings, woodworking projects, and surface protection—see Icrystal Epoxy Resin for more details.

When Layer Thickness Matters

The thickness per application becomes particularly important for projects requiring high transparency or for surface protection, such as on resin tables, art, and jewellery. Pouring too thick at once can lead to trapped bubbles or yellowing over time, while following the 1.5cm guideline ensures a durable, clear finish.
