Curing Time for Safe Demoulding of Geode Shape Moulds

← Back to Silicone moulds for coasters

Curing resin in geode-shaped silicone moulds requires patience for the best finish and durability. Knowing the correct curing time helps ensure your coasters demould cleanly and are ready for practical use.

How Long Should Resin Cure Before Demoulding?

For most heat-resistant resins used with silicone geode moulds, it is strongly advised to allow at least 72 hours for the material to fully cure before attempting to demould. This waiting period ensures the resin has hardened thoroughly, preserving your coaster’s detail and preventing any distortion or tackiness.

Removing your piece from the mould too soon can risk incomplete curing, especially if you plan to use the coaster for serving hot drinks.

• If using a layered approach, allow the base (such as a heat-resistant resin layer) to set before adding decorative layers.
• Demould gently after the full recommended time to maintain the intended smooth, glossy finish.

Tips for Best Results When Demoulding

To achieve a professional look with geode coasters, start with a 3mm layer of clear, heat-resistant resin, let it cure, and then add colours or other decorative elements. After the total resin pour, waiting up to 72 hours minimises risks of marks or surface imperfections.

Using quality moulds such as the “O” – Geode Coaster Silicone Mould – 13cm can also make removal easier and reduce chances of adhesion issues—be sure to avoid solvents and clean your mould between uses.

When Demoulding Time Really Matters

If you wish to use your geode coaster for hot mugs or as a gift, fully cured resin ensures strength and temperature resilience. Taking shortcuts can leave your piece vulnerable to bending or imprints from cups. Rushing this step undermines both the appearance and long-term function of your finished artwork.
