The Timing and Technique of Making Swirls in Epoxy Resin

Making swirls in epoxy is a great way to add a unique and creative touch to your projects. Here’s a basic guide on how to create swirls in epoxy:

1. Prepare your epoxy: Mix the epoxy resin and hardener according to the manufacturer’s instructions. Make sure that the mixture is thoroughly mixed and free of bubbles before pouring it into your mold.
2. Add color pigments: If you want to add color to your swirls, add a small amount of mica powder or other color pigments to the epoxy mixture. Be sure to mix the pigments well to ensure an even distribution.
3. Pour the mixture into the mold: Once you are satisfied with the swirls, pour the epoxy mixture into your mold. Be sure to pour slowly and evenly to avoid disturbing the swirls.
4. Create the swirls: Once your epoxy is ready and pigmented, you can start creating the swirls. One way to do this is by using a metal spatula to gently drag through the epoxy mixture in a swirling motion.
5. Let the epoxy cure: Allow the epoxy to cure according to the manufacturer’s instructions. This can take anywhere from a few hours to a few days, depending on the type of epoxy you are using.
6. Finish the project: Once the epoxy has cured, remove it from the mold and finish the project as desired.

Note: Keep in mind that it may take some practice to create the perfect swirls. You can also experiment with different techniques and tools to achieve the desired effect.

Also, keep in mind that the curing time, viscosity and the temperature of the room can affect the outcome of the swirls in your epoxy.

How to Make Swirls in Epoxy. This technique will require a little bit of babysitting to find the perfect window to do the swirls.  The best timing or window is when the epoxy is at an higher viscosity ” Honey” texture. This is where the designs you created will stay visible and won’t fade away. The best timing to start creating swirls in epoxy also depends on the type of epoxy and the desired effect.

If you are using a slow-curing epoxy, you will have more time to create the swirls before the epoxy begins to set. This is because slow-curing epoxy has a longer pot life (the time during which the epoxy can be worked with before it starts to cure) which means you have more time to create the swirls.

If you are using a fast-curing epoxy, you will need to work quickly and efficiently to create the swirls before the epoxy sets. This is because fast-curing epoxy has a shorter pot life, so you will have less time to create the swirls.

It’s also important to note that the temperature of the room can affect the pot life, for example in a hot room, epoxy will cure faster than in a cold room.

In general, it’s best to start creating swirls in epoxy when the mixture is still in its liquid state, but not too runny. This allows you to work with the mixture more easily and create the desired effect.

It’s also important to have all the tools and pigments you will use to create the swirls ready and within reach, to avoid wasting time looking for them while the epoxy is curing.

It’s also a good idea to make a test sample with the same epoxy, pigments and swirl technique you plan to use in your final project, to make sure you are happy with the final outcome.

1. It is important to maintain an ambient temperature below 22°C/72°F in order to maintain the initial viscosity of the epoxy resin.
2. You must have a certain resin thickness in order to be able to create the effects with metallic mica pigments.
3. Depending on the system and based on pot life and resin reactivity, it may take some time before the resin begins to thicken
4. The faster the epoxy or the shorter its pot life, the shorter the time window for swirling. Also the volume of epoxy used will have an impact on the temperature generated and therefore on the glass to make the swirls.
