Doing your resin craft project does not have to stop when the cold winter months begin. Resin has the ability to cure in varied conditions and temperature spectrums. The ideal condition for the resin to cure is during the summer months or in a room that is well-heated.
You can cure and create resin in cold ambient temperatures, the curing process does require a long period to achieve the end result. The hardening of the resin is needed to increase the strength and stability of the resin end product. The viscosity of the resin is increased in cold temperatures making the mixing of the resin a challenge.
Mixing resin and hardener is a chemical reaction that produces heat. The chemical reaction is affected by the surrounding room temperature which affects the rate of reaction.
In warm temperatures, the process is accelerated and the performance is better than in cold temperatures. The longer the resin takes to cure, the likelihood of the resin not curing completely. Unsure parts of the resin can be the weak points in your creations that will result in breakages.
Can you cast resin in cold weather?
Harder to Mix the resin: With the drop in temperature the more rigid and less viscous the resin solution will be. The high the viscosity the harder it is to mix the resin solution. The ingredients added to the resin don’t incorporate evenly in the resin.
When pouring the resin into your mold, the cold resin takes a long time to cure. With the curing process taking to occur there is potential for the resin to cure unevenly. The lack of constant warm temperature in the resin solution lends to the resin final product being unstable and fragile.
High probability of air bubbles: The ambient temperature in the room does affect the viscosity and thickness of your resin, With colder temperatures, the resin is much thicker and difficult to pour into your mold or mix with a hardener.
Air bubbles may be introduced when mixing colors, sprinkles, or harders in the resin, The increased viscosity allows for a long time in incorporating the ingredients and reduces strength during the bonding phase.
The air bubbles reduce the final product’s overall strength, leading to the likelihood of your craft breaking in the future.
How do you keep resin warm in winter conditions?
1. Warm up the resin – The application of heat to the resin before the pouring and mixing stage. By heating up the resin you will be able to increase the viscosity of the resin. Be careful to read the manufactures instruction to find the optimal temperature for the resin
You can warm the resin by simply using your hair dryer. Before applying the external heat first check the current temperature of the resin. Once the current temperature has been determined, you can begin blowing hot air into the resin solution. Periodically, check the temperature of the resin with your temperature until you reach the optimal temperature advised by the manufacturer.
2. Store the resin in warm condition. Have the resin ingredients stored up in a warm place, Avoid storing the resin in your shed or if you have a cold basement. The resin tends to be affected by ambient conditions. Having the resin stored in warm conditions allows for ease of use and prevents the additional steps of having to warm up the resin.
3. Stir the resin thoroughly: Having cold resin can be a challenge when incorporating hardener or decorative elements. In order to have the individual elements mixed together, the mixing needs to be done longer and thoroughly.
Having the resin warmed up by a heat gun or blow dryer is recommended before adding the resin to the container for mixing. Having a small volume container compared to the amount of resin is needed to avoid the heat dissipating during the mixing process.
Avoid using high-conductive containers like metallic containers that conduct temperature quicker compared to plastic or silicone containers. The metallic surface has the ability to absorb the heat generated during the chemical reaction between the resin and hardener.
Once the resin is fully mixed, pour the resin immediately into the mold.
4. Ensure Resin Is Cured: The curing process does take extended time in cold temperatures compared to warm conditions. The potential of the resin to cure unevenly and consistently is high. The resin project had a high chance of cracking and deteriorating.
To ensure the resin is fully cured, plan for a longer time for the resin to cure and set in your mold. Check the ambient temperature in the space that your resin will cure, and relocate the resin to warm conditions.
Read the manufacturer’s instructions to understand the recommended time it will take to cure the resin.
Turn up the heat in the room where the resin will be placed to cure. Use artificial heat sources like electric heaters, electric blankets, or heating gun.
The recommended ambient or room temperature is 72 degrees Fahrenheit or higher.
Double the time you normally have to cure your resin projects, the chances of taking out the resin too early and having the resin not cure properly negates the hard work done in creating the resin craft.
