← Back to How to use resin and silicone oil?

Achieving flawless resin casts starts with proper preparation of your moulds. Ensuring they’re clean and dry helps prevent imperfections and extends the life of your moulds.
Why Clean and Dry Moulds Matter
Dust, oils, and moisture can all interfere with resin curing, leading to marks, bubbles, or cloudy finishes. Residues inside the mould may cause sticking and reduce the clarity of your finished piece. Keeping moulds free of debris ensures each cast releases cleanly and maintains fine details.
How to Prepare Your Moulds
- Cleaning: Wash silicone moulds with mild soap and lukewarm water, then allow them to air dry completely. For stubborn residues, a soft, reusable brush such as the Reusable Silicone Resin Brush is ideal for gentle scrubbing without causing damage.
- Drying: Make certain all moisture is gone before pouring resin. Even slight dampness can lead to resin reactions or finish flaws.
- Optional Prevention: Using a small amount of silicone oil creates a non-adhesive barrier, further promoting easy release and keeping your moulds supple.
When This Matters Most
Caring for your moulds is especially crucial if you reuse them frequently or work on detailed resin pieces where clarity and finish are key. Proper preparation minimises rework and maximises the lifespan of both the mould and your creative efforts.
