Multi-material Silicone Moulds: Can I Use Gypsum or Cement?

Silicone moulds for coasters are known for their flexibility with various resin types, but what about gypsum or cement? Let’s explore your options for creating unique coasters with these materials.

Are Gypsum and Cement Compatible with Silicone Moulds?

Yes, you can use silicone coaster moulds with gypsum or cement, alongside other materials like epoxy and mineral resins. Silicone’s non-stick surface and flexibility make it easy to demould set gypsum or cement items without damaging the intricate details. Always ensure your chosen silicone mould, such as the 8.8cm Coaster Silicone Mould, is suitable for your casting material’s specific setting requirements.

Practical Tips for Successful Castings

Each casting material has its own recommendations for mixing, pouring, and cure time. For gypsum and cement, it’s essential to:

Mix according to the manufacturer’s instructions to avoid cracks or bubbles.
Poor slowly into the silicone mould to fill details evenly.
Allow full curing before attempting to demould, as premature removal can lead to breakages.
Clean your mould thoroughly after use and dry it before storing to maintain its shape and finish.

When This Matters: Mixed-Media Projects

Choosing to use gypsum or cement expands your creative options beyond classic resin art. These materials are especially popular when a more natural, stone-like finish is desired, or when you want a sturdy, weighty feel for your handmade coasters.
