18" Plain Round Mould

The 18" Plain Round Mould from Shrebhavi is a large-format casting mould designed for resin artists who want to create statement pieces — think oversized wall clocks, decorative trays, serving platters, or round table tops. At 18 inches in diameter, this mould gives you generous surface area to experiment with pigments, alcohol inks, dried flowers, geodes, and other inclusions.

Made for use with epoxy resin and UV resin (with adequate lamp coverage), this plain round mould has a smooth interior surface that releases cleanly once your resin has fully cured, giving you a glossy, polished face with minimal finishing work. Ideal for hobbyists scaling up their craft and small home-décor businesses looking for consistent, repeatable results.

• Large 18-inch diameter — perfect for wall clocks, decorative trays, and round resin art panels
• Smooth interior finish — transfers a high-gloss surface to your cured resin piece, reducing sanding time
• Clean demould release — flexible mould walls make it easy to pop out fully cured epoxy without cracking your work
• Compatible with epoxy and casting resins — works well with most two-part epoxy and slow-cure casting resin systems
• Reusable and durable — rinse clean after each use and store flat to extend mould life across multiple pours
• Versatile for inclusions — deep enough to embed flowers, glitter, foils, pigment powders, and decorative elements
• Great for beginners and small businesses — consistent shape every time means less wastage and more professional results

How to Use

Lightly coat the mould interior with a mould release spray or petroleum jelly before pouring for easiest demoulding. Mix your epoxy resin per the manufacturer's ratio, add pigments or inclusions as desired, then pour slowly to avoid trapping air bubbles. Allow full cure time (typically 24–72 hours for epoxy) before demoulding. Do not force the piece out before resin is fully hardened.

Safety Tips

Always work in a well-ventilated area when handling uncured epoxy resin. Wear nitrile gloves and eye protection during pouring. Keep uncured resin away from children and pets. Dispose of resin waste responsibly — never pour liquid resin down the drain.
