The maximum pour depths for the various TotalBoat epoxy systems are listed below. Note that the pour depths are different not only for the different epoxies, but also for the various hardener speeds within each epoxy system.
To avoid excess exotherm and an improper cure, it's important not to exceed the maximum pour depth for the particlar epoxy system you're using. Common problems associated with pouring mixed epoxy more thickly than recommended include potential yellowing, cloudiness, surface waves, cracking, shrinkage, and swirls.
|TotalBoat Epoxy System||Maximum Pour Depth, Per Layer|
|High Performance 2:1 Epoxy - Slow**||
|High Performance 2:1 Epoxy - Medium||1/8"|
|High Performance 2:1 Epoxy - Fast||Less than 1/8"|
|Traditional 5:1 Epoxy - Slow||N/A|
|Traditional 5:1 Epoxy - Fast||N/A|
|Traditional Crystal Clear Epoxy||Less than 1/8"|
|Traditional Tropical Extra Slow Epoxy||N/A|
|TableTop Epoxy||1/8" - 1/4"|
|MakerPoxy Artist's Resin||1/8" - 1/4"|
|ThickSet Clear Casting Epoxy||1/2" for river pours, slab pours; 1" for smaller castings using less than 16 oz. of epoxy|
**NOTE: For 2:1 Slow Hardener maximum pour depth: Helping to dissipate heat from the cure will generally promote a more clear, smooth surface. If heat is not allowed to dissipate sufficiently from a mold or casting, it is still possible for pours, even with these guidelines, to generate enough heat to result in an imperfect surface or a slight yellow cast in the cured surface.
