Totalboat Fathom Deep Pour Epoxy

TotalBoat Fathom is simply the best and deepest deep pour epoxy 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.
Extra long working time is ideal for large or complex epoxy pours
Once you mix Fathom’s resin and hardener components, you have anywhere from 4-6 hours to pour it. 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.
Use tints to change Fathom from clear to any color you want
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.

Step Pouring Fathom
For best results when applying additional layers of Fathom after the first pour, it’s important to note the following:
- When your project involves pouring multiple layers of Fathom, it is extremely important to wait until the previous layer has cooled sufficiently, to prevent surface distortion, yellowing, or other negative effects of excessive heat while the epoxy is curing.
- Conservatively, the safest interval to wait is a minimum of 36 hours for Fathom to cure before applying more, regardless of pour depth and ambient temperature.
- For applications when it’s important to have the shortest interval for multiple pours, wait at least 24 hours, then use an infrared thermometer to measure the temperature at the center of the epoxy mass, where the highest temperature will be recorded.
- Wait until the previous layer has dropped below 85°F, and the previous epoxy pour has firmed up enough that it will not distort when liquid epoxy is poured on it.
- Always follow the maximum pour depth based on the volume of Fathom. Once all layers are complete, the epoxy resin will be fully cured in 5-7 days.
Should I use TotalBoat ThickSet or Fathom epoxy for my project – what’s the difference?
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 16 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 | 1″ 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 | 45-60 minutes | 4-6 hours |
Demold Time | 12-24 hours | 48-72+ hours |
Full Cure Time | 5-7 days | 5-10 days |
Mix Ratio by Volume | 3:1 | 2:1 |
