Size: 1.5 Gallon Kit
TotalBoat Fathom is simply the best and deepest deep pour resin kit for thick pour applications – pour single layers up to 3″ deep in prepared molds. Pour live edge slabs and river tables up to 2″ deep per layer. The thicker layer is possible because of the low amount of heat Fathom generates and the extremely slow cure time. But the beautiful results will be worth the wait! Especially with projects created using step pours, because each layer of epoxy will meld seamlessly to produce a final piece that’s completely clear, without visible lines or cloudiness.
Once you mix Fathom’s resin and hardener components, you have anywhere from 4-6 hours to pour the crystal-clear formula. This extended working time allows you to easily pour, embed objects, pop any trapped air bubbles, and make other adjustments as needed without the stress of racing against the clock. Ideal for art projects, preserving flowers and mementos, and woodworking projects where aesthetics and control over the process matter.
The working time depends on the volume of mixed epoxy you’re using, as well as the temperature of the air in your workspace – the ideal application temperature range is 60-80°F.
Fathom is crystal-clear right out of the bottle, with a minimal blue tint to prevent yellowing, but you can easily personalize this clear liquid with mica powder, alcohol ink pigments, universal tints, and opaque pigment dispersions. Just mix the resin and hardener first, then mix in your epoxy-safe colorants.
For best results when applying additional layers of Fathom after the first pour, it’s important to note the following:
TotalBoat ThickSet and Fathom epoxies are both deep epoxies. But, if you are pouring deeper than an inch per layer, you want Fathom!
| ThickSet | Fathom | |
| Best Used For | Smaller scale castings and pours; ideal when using less than 10 fl. oz. per pour | Large epoxy projects and castings using 1/2 to 1 gallon of mixed resin |
| Advantages | Shorter de-mold time, shorter recoat time | Deepest pour depth per layer, longer working time, fewer pours, easier mix ratio |
| Max Pour Depth Per Layer | 0″ for smaller castings using less than 16 oz. of epoxy; 1/2″ for river tables, slab pours, live edge tables | 3″ for larger castings, and up to 2″ deep for river tables, slab pours, and live edge tables |
| Working Time | 30 minutes | 4-6 hours |
| Demold Time | 24 hours | 48-72+ hours |
| Full Cure Time | 3-5 days | 5-10 days |
| Mix Ratio by Volume | 1:1 | 2:1 |
