Preparing a candle mould properly is a crucial step that ensures a smooth, professional finish for your candles. Whether you’re making candles for personal use or selling them, taking the time to prepare the mould helps prevent issues such as air bubbles, rough edges, or wax sticking to the mould. In this blog, we’ll explore the importance of mould preparation, guide you through the steps for different types of moulds, and share tips to help you achieve flawless candles every time.
Why Mould Preparation Matters
Ensures Easy Release of the Candle
A properly prepared mould ensures that the candle can be easily removed once it has set. This minimises the risk of damaging the candle or the mould, allowing you to reuse your mould multiple times without hassle.
Improves Candle Smoothness and Finish
When a mould is cleaned and treated correctly, it helps create a smooth and polished surface on the finished candle. Proper preparation reduces imperfections such as rough edges or trapped air bubbles, ensuring a high-quality appearance.
Extends Mould Lifespan
Regularly cleaning and maintaining your candle moulds can extend their lifespan. By preventing wax build-up and residue, you ensure that the mould remains in good condition, providing consistent results over time.

Choosing the Right Mould for Your Candle
Types of Moulds and Their Characteristics
Choosing the right mould is essential for achieving the desired shape and finish. Different mould materials offer varying levels of flexibility, durability, and ease of use.
- Silicone Moulds: Flexible and easy to demould, making them ideal for intricate or detailed candle designs.
- Metal/Aluminium Moulds: Durable and heat-resistant, suitable for pillar and votive candles.
- Plastic Moulds: Affordable and lightweight, best for simple shapes but less durable over time.
Mould Suitability for Different Wax Types
Matching the mould type to the wax you’re using is essential for achieving the best results.
- Silicone Moulds: Suitable for soy wax, beeswax, and paraffin wax.
- Metal/Aluminium Moulds: Ideal for paraffin wax and other high-temperature waxes.
- Plastic Moulds: Suitable for paraffin and gel wax but may not be the best choice for soy wax due to its lower release properties.

Step-by-Step Guide to Preparing a Candle Mould
1. Clean the Mould Thoroughly
Start by washing the mould with warm, soapy water to remove any dust, residue, or previous wax. Ensure the mould is completely dry before use, as any moisture can affect the quality of the wax and create imperfections in the final product.
2. Apply a Mould Release Agent
A mould release agent makes it easier to remove the candle after it has set. The type of release agent depends on the mould material:
- Silicone Moulds: Use a light coating of vegetable oil or a specialised mould release spray.
- Metal/Aluminium Moulds: Apply a silicone-based release spray or lightly oil the inside of the mould.
- Plastic Moulds: Use a thin layer of mould release spray to ensure easy demoulding.
3. Preheat the Mould (Optional but Recommended)
Preheating the mould can prevent air bubbles and promote even cooling. Warm the mould slightly by placing it in a warm oven for a few minutes or using a heat gun to gently warm the surface. This step helps the wax flow smoothly and prevents inconsistencies.
Additional Tips for Best Results
Check for Damage or Cracks
Before pouring wax, inspect the mould for any cracks or defects. Damaged moulds may cause leakage and result in uneven candle shapes.
Position the Wick Correctly
Secure the wick in place before pouring the wax. Use a wick holder or centre it manually to ensure an even burn.
Test with a Small Batch First
If using a new mould, consider doing a test pour to identify any potential issues before making larger batches. This allows you to adjust your technique if needed.
Key Takeaways
Properly preparing your candle mould is essential for creating smooth, professional-quality candles. From cleaning and applying a release agent to preheating and checking for alignment, each step plays a crucial role in ensuring a flawless finish. Whether you’re using silicone, metal, or plastic moulds, taking the time to prepare them correctly will extend their lifespan and enhance the quality of your candles. Start with these simple steps, and you’ll be well on your way to crafting beautiful candles that look as good as they smell!
