Many epoxy resin products may be poured up to 2 inches thick with little to no issues, so long as you have a steady hand and have prepared the epoxy properly before pouring it, as well as allowing it enough time to cure properly.
That said, some epoxy resin may only be poured up to ⅛ of an inch at a time in order to cure properly.
Pouring these epoxy resin products in depths that exceed their recommended maximum is a sure way to end up with an epoxy finish that is cracked and full of bubbles.
Other epoxy products, such as high-quality deep pour epoxy resins, may be poured to depths of 3 inches to 4 inches.
One of the most important aspects of pouring epoxy successfully, however, regardless of depth, is your skill and patience levels.
How Do I Pour Epoxy 2 Inches thick?
To properly pour epoxy 2 inches thick, you need to first properly mix the product, including any additional ingredients like mica powder or epoxy dye you want to add, and have a steady hand.
Further, it is absolutely crucial for you to allow enough time in between layers if you are stacking pours in order to achieve a certain overall thickness.
The standard amount of time that it takes 2 inch thick epoxy pours to dry, harden, and cure properly altogether is 7 days.
The amount of time it takes for your 2 inch thick poured epoxy to fully cure, however, depends on various factors such as the specific type of epoxy resin product that you use, the material you are bonding the epoxy too, and/or the items you are encasing in epoxy.
Additional factors like the temperature, amount of direct sunlight, and artificial light exposure also have a serious impact on the curing process of epoxy poured 2 inches thick (or thicker).
Should I Do a Single Pour 2 Inches Thick?
For all of the above-mentioned reasons, pouring epoxy resin 2 inches thick in a single pour isn’t always the best course of action.
Beginners working with epoxy resin, specifically pouring it in thicker layers than ⅛ inch to ¼ inch layers, may have a smoother experience pouring four 0.5 inch layers or two 1 inch layers prior to pouring a full 2 inch pour.
The Takeaway Answer
With a bit of instruction, the right product, and a bit of patience, just about anyone can pour epoxy 2 inches thick with little to no issues in the final product.
That said, don’t forget to keep your skill level in mind and avoid single epoxy pours thicker than ¼ of an inch or so.
