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

1 - MEASURE

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.

IMPORTANT!

  • **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

Lots I like about working w this resin
By TovaGoldArt from Las Vegas

Verified Purchase

I'm working on a large-scale project that includes making 3,000 gummy bears ina. rainbow of colors that I'm sharing online as I go. I switched to Total Boat after seeing another maker use it. It doesn't leave bubbles on top of my poured parts. It dries harder and "crisper" than the resin I used prior. I use the pre-measured pump which makes it so easy to keep making new batches. For this application, I like that it's a thinner pouring consistency than other resins I've used.

Bottom Line Yes, I would recommend to a friend

Easy to use. Great for large projects without pressure pot
By Chanisaw Dagger from San Diego, CA

Had a great experience with this product. Our project yellowed a tad bit, but, we started pouring during a heatwave and ambient temps were in the 90's and possibly 100's in the shop. We are aware that is not the recommended ambient temp but, we had already started. We made a 4 1/4" slab 16 x 26". Based on the temp we pours either 1/4" or 1/2" pours. I think it was 12 pours in total. Pleased with it. Minor air bubbles formed but, we think it was from the bones. We found a mummified cat under my house running power and decided to cast it in epoxy. I think air escaped from the rib bones as the layers cured over 7 days.

Melamine stuck to the bottom so the back is scuffed up. Will buff out and hopefully this is see through in the end.

Great, but stay in the lane…
By Mooman from Cary NC

Verified Purchase

The thick set was excellent for the half-inch pours. But it had a horrible response when I tried to do a thin coat over top of my last half inch pour. Although the website and advertisement notes that this material can be used as a thin layer…, I would highly recommend not using it for this application. In speaking with the technical support team, they confirmed that it may not always have positive results as a thin layer, the recommendation is for the high-performance epoxy in this case. The thin pour did not cure and I had to chisel it all out after several days at the advice of the technical team (in and around rocks ) over several hours until I got back to the cured half inch pour below. Subsequently, I applied the high-performance epoxy and there is thankfully no signs of the chiseling marks left behind (note, I did add a pinch of blue coloring just to help cover any white marks that may appear through the epoxy from my chisel). Bottom line, great product but be sure to stay in it's lane- thick set pours only 😁👍
