  • Our take on the TotalBoat ThickSet Fathom Deep Pour Epoxy Resin

    TotalBoat ThickSet Fathom is a two-part, low-viscosity epoxy made for deep pours in one go, such as river tables, slab pours, bar tops and castings. Its slow cure lets thick layers set without the heat buildup that cracks thinner hobby epoxies, and the UV-resistant formula is meant to slow yellowing. The cured resin is rigid and hard as stone, so it suits furniture and cast pieces rather than anything needing flex. Against cheaper casting epoxies it trades a higher cost for depth per pour and clarity; against thin laminating epoxies it is the better choice for volume work but overkill for seal coats and small repairs.

    Lowest price we've seen: $44.99 on Nov 10 at Amazon. Tracked across 12 stores since Nov 10.

    What reviewers say

    Owners of deep-pour kits generally report clear, bubble-free results on thick river table and slab pours, with the slow cure doing what it promises. Complaints center on the long wait before demolding and on yellowing or cloudiness when pours are rushed or mixed off-ratio.

    What people mention
    • ClarityPraisedOwners say thick pours come out clear and glass-like with few visible bubbles.
    • Cure timeCriticisedThe slow cure means a full day or more before parts can be demolded, which slows production.
    • YellowingMixedThe UV-resistant formula helps, but some users still report yellowing in direct sun.
    • BubblesPraisedLow viscosity lets trapped air rise out, so fewer bubbles than with thicker epoxies.
    • RigidityMixedThe hard, stone-like cure suits tables and castings but can crack where wood moves.

    Questions and answers

    How thick a layer can I pour at once?
    Fathom is built for deep pours, so thick layers are its purpose. Keep the workspace within the temperature range on the label and pour in one continuous session for the clearest result.
    Do I need a seal coat first?
    Yes on porous wood. Brush on a thin seal coat to stop air escaping into the deep pour and causing bubbles, then pour the main layer once it has set.
    How long before I can demold?
    Plan on about 24 hours before demolding. Cooler rooms stretch that; warmer rooms shorten it. Full strength develops over several days.
    Will it yellow in sunlight?
    The formula is UV-resistant to slow yellowing, but no clear epoxy is fully immune. Keep finished pieces out of long direct sun for the best color retention.
    What can I use it on?
    Wood, concrete and metal with the right surface prep. It is made for river tables, slab pours, bar tops, countertops and cast sculptures.
    How much does a kit cover?
    One gallon of mixed Fathom covers about 231 cubic inches, so a 4-gallon kit covers roughly four times that. Measure your mold volume before mixing.
    Where is the TotalBoat ThickSet Fathom Deep Pour Epoxy Resin cheapest?
