How to Avoid Overfilling the Mould for Resin Christmas Ornaments

Q: Tips for Controlled Resin Pouring

Pre-measure your resin: Use a small jug or syringe to measure the right amount before pouring. Work on a flat, stable surface: This keeps the resin evenly distributed and prevents accidental overflows. Pour slowly and pause: Pour in stages, allowing the resin to spread naturally. Stop when the liquid sits just shy of the mould’s edge. Check for air bubbles: As the mould fills, look for trapped air and gently tap the mould to release bubbles before finishing the pour. If you’re using a beginner-friendly kit like the UV Resin Kit with 5 Christmas Silicone Moulds , start with smaller pours and build confidence with practice.

How to Avoid Overfilling the Mould for Resin Christmas Ornaments

Achieving a flawless resin Christmas ornament starts with pouring your resin into the mould correctly. Overfilling can lead to spillage, uneven surfaces, and difficulties with demoulding. Here we’ll explore practical ways to prevent overfilling and ensure every ornament looks its best.

Why Mould Fill Level Matters

Resin naturally self-levels, so even slight overpours can result in spilled resin over the edge of your mould. This not only wastes material but can also create sharp or uneven ornament edges that require extra trimming afterwards. By filling your mould just beneath the rim, you’ll allow space for the resin to settle and minimise clean-up.

When This Matters Most

Avoiding overfilled moulds is especially important when you want crisp ornament shapes and quick, clean demoulding—key for making gifts or when working with detailed designs during the busy Christmas season.
