Temperature The ideal room temperature for mixing ArtResin epoxy resin is between 75 and 85 degrees F or 24 – 30 degrees C. If it’s colder than that, the resin will be thicker and harder to mix, will have more bubbles and will take longer to cure until it’s dry to the touch.
What happens if you pour epoxy resin too thick?
If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. The rule of thumb is if you can make an imprint with your fingernail in the epoxy you can pour again and the epoxy will chemically bond to the previous layer.
Will thick epoxy cure?
Generally, epoxy cures faster when the air temperature is warmer. Exothermic heat is produced by the chemical reaction that cures epoxy. In a thicker mass, more heat is retained, causing a faster reaction and more heat. The mixing container’s shape and the mixed quantity have a great effect on this exothermic reaction.
Why is my epoxy not smooth?
The most common cause for uneven epoxy resin is often not using the correct mixing ratio, or even using hardener and resin that is too old. These problems can be prevented by ensuring your work area is well ventilated, not too humid, and using a torch to heat the epoxy and allow the air bubbles to escape.

Why is my resin rubbery?
The main reasons your epoxy resin is flexible and soft boil down to not enough curing time, improper ratios of base resin and hardener, not mixing well, pouring too thin, expired or compromised resin, and moisture in your epoxy prior to cure- resulting in an epoxy resin that rubbery and flexible.
Why is my resin streaky?

How thick can I pour epoxy?
As long as you pour in 1/8″ layers, you can go as thick as you like. The reason we recommend this thickness is two-fold: first, it allows the bubbles to escape properly, and second, it avoids any excessive overheating of the resin. So for best results always pour in a 1/8″ layer, and you’re good to go!Feb 6, 2021.

Wet sanding with waterproof sandpaper is often the best approach to sanding cured epoxy resin. Wet sanding removes unevenness while you are sanding, reduces clogging of the abrasive paper and drastically reduces the amount of dust emitted into the air.
Why is my epoxy not sticking to my cup?
Mixing ratios can greatly affect how your piece will cure. If the mixing ratio is off or not completely mixed properly, this can cause the resin to remain tacky, or have soft spots. To ensure that you have the proper mixing ratios measured in measuring cups, and to ensure that you are mixing by volume.
Can I pour multiple layers of epoxy?
Can I Apply Multiple Coats Of Epoxy Resin? Yes, you can apply a second coat of resin if you need to fix a mistake or a surface imperfection. You can also pour multiple layers if you need to cover areas of high relief, if you’re pouring into a mold or if you simply like the look of a thicker coat.
