Deep Pour Epoxy Resin Kit 51OZ - Clear 2-4 in Casting

In this review of the Deep Pour Epoxy Resin Kit 51OZ, the bottom line is simple: this kit is best for makers who need a single, thick pour with clear, bubble-free results. The combination of a 34oz Part A and 17oz Part B mixed 2:1 by volume delivers up to 4 in pours without repeated layering, which is the single biggest benefit for builders of river tables, large casts and encapsulations looking to reduce steps and errors. It is worth noting the cure speed varies by piece size, so plan projects accordingly.

Key Features

• Deep pour capability: Allows single pours from 2 to 4 in thick, saving time and reducing the risk of seams in large casts.
• Crystal clear formula: Produces a high-gloss finish with UV resistance and anti-scratch properties to preserve clarity over time.
• Long working time: Offers about 80 minutes of working time so you can position and de-bubble larger pours before gelation begins.
• Low viscosity and bubble control: Mixes smoothly at a 2:1 ratio and levels well, helping reduce trapped air for clearer results.
• Low odor and practical hardness: Low-odor formulation that cures to a hard finish (around 85D) suitable for functional surfaces and encapsulation.
• Compatibility with colorants: Works with mica powders and alcohol inks for vibrant effects while maintaining clarity.

Who It's For

This kit is ideal for woodworkers crafting river tables, makers casting thick blocks or encapsulating objects like flowers, and hobbyists who prefer fewer pours and a streamlined workflow. The clear, low-yellowing formula and anti-scratch surface make it a solid choice for decorative and functional pieces that need long-term clarity.

It is less suitable for very small, thin items where long cure times (small pieces can take approx. 3 days) may delay results, or for users who need extremely fast cures for rapid production. Beginners should still be comfortable following the 2:1 mix ratio and basic de-gassing technique to get best results.

Pros & Cons

Pros

• High clarity and low yellowing deliver attractive, professional-looking casts.
• Deep pour in a single go saves time and reduces layering errors for large projects.
• Generous 80 min working time and low viscosity make mixing and leveling straightforward.
• Low odor and hard cured finish suitable for tabletops and encapsulations.

Cons

• Small items cure more slowly, which can extend project timelines compared with thin-pour resins.
• Cure time varies by mass, so controlling temperature and volume is important to avoid unexpected curing behavior.

Our Verdict

The Deep Pour Epoxy Resin Kit 51OZ is a practical choice for makers who need clear, deep casts without the hassle of multiple layers; its long working time, low viscosity and UV-resistant finish provide good value for river table builders and encapsulation projects. Buyers should account for variable cure times on small pieces, but for large pours this kit streamlines the process and delivers professional-looking results.

Frequently Asked Questions

How deep can I safely pour in one go?
You can pour between 2 and 4 in in a single pour as intended, but monitor exotherm on very large volumes and control ambient temperature.

What is the correct mix ratio?
Mix at 2:1 by volume: 34oz Part A to 17oz Part B in this kit, stirring thoroughly to avoid uncured spots.

How long until the piece is usable?
Initial cure is around 48-72 hours for typical casts; small items may take about 3 days to fully cure depending on mass and environment.
