Next Step
Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Measurement diagram
Total order, lift count and batch count are different
A 48 × 14 × 2.5 in cavity holds 7.2727 gal before waste, or 8 gal with the example 10% allowance. If your product actually permits a 1 in layer under your conditions, the depth calculation gives three lifts. If it also specifies a maximum mixed batch, enter that separately: a lift can require more than one batch. Neither the order quantity nor a computed lift count establishes a safe mixing volume or recoat schedule.
Product data before mixing
Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.
What this calculator covers
- Estimates material for thick casts where product depth limits matter.
- Turns one total volume into staged lifts you can actually execute.
- Helps you avoid choosing a resin that cannot safely handle the target section.
How to measure or set the inputs
- Enter the full finished cavity size, then set the maximum lift depth from the product you are considering.
- Treat the lift guidance as part of the buying decision, not as an afterthought after you order resin.
- Use the total quantity and the staged-lift output together when planning mixing sessions and shop time.
Common mistakes that cost money
- Assuming the total quantity is enough information for a deep cast.
- Ordering resin without checking maximum pour depth and cure temperature limits.
- Using a coating or table-top product for a section that really needs deep-pour behavior.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
Why do I need layer guidance if the total volume is already correct?
Because the total quantity and the pour schedule are different decisions. A project can need the right total amount and still fail if each layer is too thick.
What should I do if my target depth exceeds the product lift depth?
Plan staged pours and confirm the cure window between lifts on the product documentation. The calculator shows the quantity problem, but the resin data sheet still controls the actual execution limits.
Is deep-pour resin always better for thick projects?
It is often the right starting point, but not automatically. Cure speed, ambient temperature, clarity goals, and the actual section thickness all matter. Use this page to narrow the product class, then compare technical sheets.
