Frequently Asked Questions

Q: What materials can I use with these round silicone coaster molds?

A: These silicone coaster molds are compatible with a wide range of casting materials including epoxy resin, UV resin, concrete, cement, and polymer clay. They are designed for casting applications only — not for surface-coating resin techniques.

Q: How do I remove my finished coaster from the silicone mold?

A: Once your resin or other casting material has fully cured, simply flex and peel back the silicone mold gently, then push from the underside. The flexible silicone releases the coaster smoothly without sticking, and the finished surface will have a glossy, mirror-like shine with minimal polishing needed.

Q: Are these molds reusable, and how do I clean them?

A: Yes! These silicone coaster molds are fully reusable and recyclable. After each use, wipe them clean with a soft cloth or rinse with warm water. Avoid using abrasive scrubbers so you preserve the smooth interior surface for future casts.

A: Each round silicone coaster mold measures approximately 9 cm (about 3.5 inches) in diameter — a standard coaster size that fits most mugs, glasses, and cups perfectly.
