Staged deep-pour planner
Too deep for one pour? Pick your epoxy and EpoxyPlan splits the job into even layers inside the maker's limit, with how much to mix each time and when each layer can go down.
Why stage a deep pour?
Epoxy cures by giving off heat, and a thick mass holds that heat. West System warns that 100 g of mixed epoxy can reach 400 °F in a cup, and TotalBoat's Fathom data sheet notes a mass "poured thicker than advised" can hit 200–300 °F or more, leading to cracks, shrinkage in corners or yellowing.
Splitting the job into even layers under the product's limit keeps each pour manageable. EpoxyPlan uses the fewest equal layers that fit the limit, so each layer cures the same way.
Temperature matters too
"At warmer ambient temperatures, the epoxy will cure faster and generate more heat. Limit the depth of each pour, especially when working in warm conditions" (Epoxyworks). GlassCast 50's data sheet is a clear example: into wood, 25 mm per layer at 15–20 °C, but only 18 mm at 25 °C.
The recoat window
Pour too soon and heat builds up; wait too long and the next layer may not bond without sanding. Each product's window is different: Fathom wants at least 36 h, Stone Coat Ultra Deep goes on at gel stage (17–22 h), and MirrorCast can be repoured after 10–14 h depending on width, with no sanding needed within 72 h.
