TotalBoat ThickSet Clear Casting Epoxy Kits

TotalBoat ThickSet Clear Casting Epoxy is perfect for thick casting, embedding & molding projects. Its water-clear, two-part formula makes DIY projects easy—just measure, mix, and pour! Simple 3 parts resin to 1 part hardener mix ratio creates a deep, glass-like finish on bars, counters and tables, highlighting the surface itself or the creative objects you've embedded, such as shells, bottle caps, and photos.

ThickSet lets you pour deeper single layers than you can with a traditional tabletop epoxy. For large pours (e.g., tables or slabs), you can pour single layers 1/2-in. to 1-in. deep. Small molds can be poured in single layers up to 2 in. deep. Long working time lets you experiment & have fun!

Choose kit size: 1.3 Quart, 1.3 Gallon, or 4 Gallon. Kits include 2 qt. size mixing cups, 2 stir sticks, 1 spreader & 1 pr. of lg. latex gloves.

Easy Instructions for TotalBoat ThickSet Epoxy


Pour 3 parts resin and 1 part hardener by volume into a clean mixing cup (DO NOT mix more than 1 total gallon of material at a time).

2 - MIX

Stir for 2-3 minutes to mix thoroughly. Pour into a clean mixing cup and stir for another 2-3 minutes.

3 - POUR

Pour slowly, to minimize air bubbles. Use the spreader to help level out the layer. The maximum single-pour depth is 1" for large pours, and 2" for casting in small molds.

Step pouring additional layers: Wait until the previous layer is cool, but still soft enough to indent with a fingernail, and pour the next layer of ThickSet directly on top.


  • Multiple, step pours are recommended, rather than one thick coat, which will generate excessive heat, distorting the surface.
  • Do not place items hotter than 125°F on the cured surface.
  • Not designed for continuous UV exposure. If the item will be used outdoors, the cured surface must be coated with a UV-filtering varnish to prevent yellowing and fogging.

Should I Use TotalBoat ThickSet Epoxy or TotalBoat TableTop Epoxy?

Both of these epoxies give you beautiful results for crystal-clear coating, casting, embedding or encapsulating projects. However, TotalBoat TableTop Epoxy is more of a 'coating' epoxy, and TotalBoat ThickSet epoxy, is more of a 'casting' epoxy designed for thicker pours.

TotalBoat ThickSet Epoxy Advantages

  • Requires fewer pours to achieve final thickness of 1/2" and more
  • Reduces possibility of banding (ability to see individual layers)
  • Gives you longer working time at room temperature

Designed for thick casting, ThickSet allows you to do deeper single-layer pours than you can do with TotalBoat TableTop Epoxy. For example, you can pour a single layer of TotalBoat ThickSet 1/2"-1" deep when pouring into large areas or molds, and up to 2" deep when pouring into small molds.

TotalBoat TableTop Epoxy Advantages

  • Faster cure time for coating and shallow-depth embedding projects
  • Simpler 1:1 mix ratio (ThickSet is 3:1)

The maximum single-layer depth for TotalBoat TableTop Epoxy is 1/8"-1/4".

Amazing Product


I've used many brands including some of TotalBoat's other products. This deep pour epoxy is by far one of the best for the price. Make sure to understand that if you're doing a huge river table that you may need to break it into multiple pours.
