Core volume
River table: use the full outer rectangle of the pour area.
Slider step uses your unit: e.g. in cm, 10 = 1.0 cm.

Mixing (typical)
Stir slowly 3–5 minutes, scrape sides and bottom, avoid whipping air. Check your product: some need 2-part mix by weight instead of volume—use a scale if required.

How to calculate epoxy volume?
Use base area × thickness in consistent units. For a rectangle, area = length × width. For a circle, area = πr² = π(d/2)². Convert cubic centimeters to liters by dividing by 1000.
What is the epoxy mix ratio?
Two-part systems specify how many parts resin to parts hardener (by volume or weight). The split here is by volume unless your label says otherwise.
Common mistakes
- Underestimating thickness (doming, uneven subsurface).
- Wrong ratio or incomplete mixing → sticky spots.
- Single pour too thick for the product—use multiple layers.

FAQ
- How much epoxy do I need?
- Compute volume from your mold or surface area and pour depth, then add a waste allowance.
- How do you mix epoxy resin?
- Measure parts accurately, mix thoroughly for several minutes, then pour within pot life.
- Epoxy coverage per liter?
- Divide one liter by the thickness expressed in meters to get approximate area in m² for a flat film.
- How thick can I pour?
- Follow the manufacturer’s max per layer; deep pours may need a specialty resin or multiple layers.
