Product Details

TotalBoat ThickSet Clear Casting Epoxy is a deep pour resin system ideal for thick casting, embedding & molding projects. Water-clear, 2-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 & photos.

ThickSet lets you pour deeper single layers than traditional tabletop epoxy. For large pours (river tables or slabs), pour single layers up to 1/2 inch deep. Pour small castings (using less than 16 oz. of epoxy) up to 1 inch deep. Long working time lets you experiment & have fun! Cured epoxy is BPA-free, safer for food contact.

Choose Kit size: 1.3 QT, 1.3 GAL, 4 GAL or 8 GAL.

Note: ThickSet Epoxy is also available in a 55 gallon kit. Please contact us for pricing.

Info & Guides

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).

NOTE: For convenience dispensing smaller amounts of ThickSet, try our new calibrated 3:1 Epoxy Pumps. No guessing, no mess, and a perfect cure every 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 a 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.


  • **Environmental conditions are extremely important to the quality of the cure, and to achieving the best clarity and surface finish. Depending on the overall mass of epoxy being poured at a single time, the depth that it is poured, and the ambient temperature, excessive heat may build up from the reaction, causing potential yellowing, cracks, or other shrinkage. Helping to dissipate the heat may help promote the best results. For the epoxy to cure fully, the ambient temperature must be between 65°F and 80°F. When pouring for larger projects, such as slabs or tables, do not exceed a pour depth of 1/2 in to 1" to prevent yellowing or excessive heat from the cure.
  • 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".

For deeper pours, should I use TotalBoat ThickSet or ThickSet Fathom epoxy - what's the difference?

TotalBoat ThickSet and ThickSet Fathom epoxies are both crystal clear resin systems that can be poured deeper than traditional epoxy, and both are ideal for castings, river tables, and slab pours, but if you want to do really deep pours, use ThickSet Fathom because you can pour it in thicker single layers than ThickSet. The table below contains more information to help you decide which ThickSet formula is right for your project.
ThickSet ThickSet Fathom
Best Used For Smaller scale castings and pours; ideal for castings using less than 16 fl. oz. per pour Larger scale projects and castings using 1/2 to 1 gallon of mixed epoxy
Advantages Shorter demold 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 2-4 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

I am a first time epoxy user and spent several months researching which epoxy was the best. It came down to Total Boat epoxy and one other brand. I decided on total boat because of how long they have been in the game. I'm glad I went with Total Boat Thickset! My project turn out amazing. Easy to use. Make sure you mix your epoxy and it will set how it is supposed to!

Great product
By David Smith from Venice, Fl.

Verified Purchase

Have used this a couple of times and am very happy with it. Works as promised drying time is acceptable and dries crystal clear. My suggestion and I highly recommend is to use a vacuum chamber, especially since it is a thick pour. Would recommend this and there other products as everything I have used has worked perfectly as long as instructions are followed. Nice to get a product that does what it says.

Bottom Line Yes, I would recommend to a friend

Fantastic for Deep Pours
By Michelle from Albuquerque, NM

Verified Purchase

My first order of total boat arrived to my house completed spilled and saturated the entire box. I reached out to customer service and they sent me a replacement order immediately. After receiving the replacement, I used the epoxy for a custom order for a friend where I poured it into a large silicone mold with photos inside. I was able to pour around an inch at a time, and although the curing time is longer than I'm used to, it came out flawlessly! No bubbles, just clean perfection. This really is the best deep pour expose I've worked with.

Bottom Line Yes, I would recommend to a friend

Woks like they say
By Captain Wade from Mandeville, LA

Verified Purchase

This is the second time using this product, and I'm filling holes and checks in sinker cypress with it. When mixed with the "metallic" color packets it is really striking. My pours have been about 3/4" thick, done at the end of my workday. Plenty of working time. When I return to the shop the next day I can dent it with my fingernail, so I can make another pour without sanding to reach the desired thickness.

Bottom Line Yes, I would recommend to a friend
