Minimum Cure Time Between Icrystal Pours

Recommended Timing Between Layers

For Icrystal epoxy resin, it is best to wait until the first layer is slightly tacky to the touch before pouring the next. This typically takes around 4–6 hours but may vary based on temperature and humidity in your workspace. Pouring when tacky ensures a strong bond between layers and helps prevent issues such as cloudiness or separation.

Practical Guidance for Multi-Layer Pours

• Prepare your space so you can monitor the curing progress—warmer conditions may speed up the process.
• Use a small tool or gloved fingertip to gently check if the surface is no longer runny but still slightly sticky. Avoid waiting until fully cured, as this can impact interlayer adhesion.
• Keep each individual pour within the recommended maximum layer thickness; with Icrystal, do not exceed 1.5cm per layer.

When This Timing Matters

Correct timing is essential for layered projects like resin art, jewellery, and protective surface coatings. Adhering to the window between tacky and cured gives you the strongest, clearest finish without visible joins.
