Having a deep pour is an important quality of resin for a variety of epoxy projects. Whether you’re trying to perfect a homemade river table or cast artistic epoxy pieces, using deep-pouring resin ensures a smooth application. In addition to adding a creative touch to your epoxy projects, a thick pour improves the quality and longevity of your items to ensure the epoxy maintains its shine. If you’re searching for epoxy resins with a high viscosity, you have come to the right place. After years of testing and learning epoxy resins, I’ve put together a list of the 9 best epoxy resins for deep pouring for various projects.

1. EcoPoxy FlowCast

If you’re looking for an epoxy resin with pours up to 1.5 inches thick, the EcoPoxy FlowCast is the ideal resin for you. Made with eco-friendly ingredients, this product is beloved by many for countless projects. From river tables and ocean tables to deep pour applications in silicone molds, the EcoPoxy FlowCast allows users to cast 1/2 to 1.5 inches thick.

Because the EcoPoxy FlowCast casts thick pours, the epoxy boasts an incredibly strong bond and high durability. For this reason, this brand is excellent for large projects such as river tables, furniture, and other epoxy items. No special tools are required for crafting with EcoPoxy FlowCast epoxy resin.

Another beneficial feature of the EcoPoxy FlowCast is its transparency. Due to its incredible air release and low exothermic heat buildup, EcoPoxy FlowCast produces a clear, solid finish that resists stress cracking. Because the epoxy cures to a water-like appearance, the resin can be colored with one of EcoPoxy’s many pigments.

EcoPoxy is a high-quality brand dedicated to manufacturing bio-based epoxies made from annually renewable resources. In addition to using bio-based ingredients in their products, EcoPoxy is always improving and producing better formulas. In turn, you can always be guaranteed a high-grade, smooth epoxy finish.

2. Chill Epoxy Resin Deep Pour

When it comes to epoxies with deep pours, nothing quite beats the thickness of CHILL Epoxy Resin. CHILL DEEP POUR, manufactured by POLYMERES Technology, allows for pours between 2.0 to 2.5 inches thick. Furthermore, this epoxy may have a mass of 90 to 110 liters, depending on the design you’re casting.

While the CHILL DEEP POUR is excellent for a variety of projects, it is widely used for casting river tables. Its high precision and transparency ensure a glossy finish in a single casting. Moreover, the epoxy’s long lifespan allows users to mix several liters of resin at a time, and thus pour a large quantity of resin.

Known for its high quality, the CHILL DEEP POUR is extremely easy to use for numerous projects. Unlike other deep-pour epoxy brands that require fans and air conditioning to cure properly, the CHILL DEEP POUR features a controlled exothermic reaction for an effortless finish. The epoxy resin cures in 7 days without the need for cooling devices during the curing process.

Although CHILL DEEP POUR is slightly more expensive than other brands, its high-quality and unmatched performance makes it well worth the initial cost. No matter what project you’re working on, CHILL DEEP POUR will produce a glossy finish that lasts for years to come.

3. Ice Epoxy ICECAST

When casting epoxy resin with a thickness greater than 1-inch, Ice Epoxy ICECAST is my go-to product for thick applications. With the ability to pour up to 4-inches, ICECAST is ideal for casting, potting, and embedding applications. The low color and low viscosity allow for a bubble-free, crystal-clear appearance for a number of art and hobby applications.

The high quality of ICECAST is one of the many features that make this brand an ideal choice for a variety of projects.

4. Mas Deep Pour Epoxy

If you are designing an ocean or river table, the Mas Deep Pour Epoxy may be the best epoxy brand for you. Made specifically for deep pours, Mas Deep Pour Epoxy is ideal for casting, encapsulating, and molding applications. This high-quality epoxy is a two-component, 100% solid formula resistant to scratches and yellowing. Available in 1.3-quart, 1.3-gallon, and 4-gallon sizes, the Mas Deep Pour Epoxy casts between 0.5-inch to 1-inch or more.

As a slow-cure epoxy resin, the Mas Deep Pour Epoxy cures within 24 to 36 hours at 70°F. Once fully cured, the epoxy resin will feature a glassy finish with an extended gel time. The increased gel time helps minimize exotherm and improve air release during the application process.

Note that there are several factors to consider when seeking a maximum casting thickness. The workspace temperature, mixing quantity, material temperature, and project dimensions may affect the epoxy’s ability to cast deep pours. For best results, do not exceed a 0.5” casting thickness for a full mixed 1.3-gallon kit. Similarly, avoid exceeding 1” for a half mixed kit. If you desire thicker castings, consider pouring multiple layers of epoxy.

Keep in mind that this brand of epoxy is an advanced deep pour epoxy resin system. Do not attempt to pour this epoxy in working temperatures above 75°F. Additionally, avoid pouring a large quantity of epoxy in one area, as this may lead to shrinking and yellowing. Be sure to carefully follow the casting instructions, as Mas Deep Pour Epoxy is a sensitive epoxy product.
