TotalBoat Fathom Deep Pour Epoxy Resin Kit - 2-3in Crystal Clear

In this review of the TotalBoat Fathom Deep Pour Epoxy Resin 1.5 gallon kit, the bottom line is simple: if you need a reliable, crystal-clear deep pour resin for projects like river tables, flower preservation, or large molds, this kit delivers professional clarity and long working time. The reviewer found it especially useful for pours up to 2 to 3 in per layer, with dependable bubble release and UV resistance that help keep finishes looking fresh. It is best suited to hobbyists and woodworkers who want a forgiving, low-viscosity formula with extended work and cure times.

Key Features

• Deep pour capability: Allows single-layer pours up to 2 in for large projects and up to 3 in for small silicone molds, reducing layering steps and seams.
• Crystal-clear, high-gloss finish: Produces glass-like clarity that resists yellowing and enhances wood grain and embedded objects.
• Low-viscosity, tintable formula: Mixes and pours easily and accepts alcohol inks, pigments, or mica for custom colors without trapping excessive bubbles.
• Extended working time: Offers a 4-6 hour working window on a 21:1 mix, giving time to position items and remove bubbles before gel.
• Durable protection: The cured resin resists heat, moisture, scratches, and stains for long-lasting results on furniture and art.
• UV resistance: Built-in UV inhibitors help protect embedded items and color stability over time.

Who It's For

This kit is aimed at DIY woodworkers, makers, and craft artists who build river tables, deep castings, or preserved-flower displays and want professional-grade clarity without complex procedures. The long working time and low viscosity make it friendly for those who need to embed objects or layer pigments during a single session.

It is less appropriate for users needing very rapid cures or many thin pours where a fast set epoxy is preferred, or for environments where maintaining the recommended 65-80F workspace is impossible, since temperature control helps ensure a consistent cure and the best finish.

Pros & Cons

Pros

• Excellent clarity and high-gloss finish that showcases wood and embedded items.
• Long 4-6 hour working time lets users adjust embeds and remove bubbles easily.
• Low viscosity and good bubble release make mixing and pouring straightforward.
• Resists yellowing and surface wear thanks to UV resistance and durable formulation.

Cons

• Requires temperature control (65-80F) and patience for full cure; not ideal if very fast turnaround is needed.
• Deep pours still need attention to layering limits depending on mold size to avoid heat issues.
