8in1 Round Agate/Zigzag Coaster Mould

The 8-in-1 Round Agate/Zigzag Coaster Mould is a flexible silicone mould set that lets you cast eight coasters in a single pour. Each cavity features either an agate stone-inspired wavy pattern or a bold zigzag design — giving your finished coasters a premium, marbled look without any extra effort. Ideal for epoxy resin, UV resin, and concrete casting.

Whether you are making coasters for your home, gifting them, or selling handmade products as a small business, this mould saves time and material. The food-safe-grade silicone releases cured resin cleanly, preserving sharp pattern detail every time.

• 8 cavities in one mould — cast a full coaster set in a single session
• Two distinct designs: agate wavy pattern and zigzag texture for variety
• Compatible with epoxy resin, UV resin, concrete, and air-dry clay
• Flexible silicone body allows easy demoulding without cracking your piece
• Smooth inner surface produces a glossy, polished coaster face
• Reusable and easy to clean — rinse with warm water after each use
• Great for hobbyists, home décor projects, and small resin businesses

How to Use

Mix your epoxy resin as per the manufacturer's ratio, add pigments or alcohol inks for an agate effect, and pour into the cavities. Allow to cure fully (typically 24–48 hours for epoxy) before demoulding. For UV resin, cure each layer under a UV lamp for 2–3 minutes.

Safety Tips

Always wear nitrile gloves and work in a well-ventilated area when handling epoxy or UV resin. Keep uncured resin away from children and pets. Do not use this mould for food preparation or direct food contact.
