Tips for Better Results
Always prepare 5–10% extra resin to compensate for mixing losses and material left in the cup.
Measure the internal dimensions of your mold, not the external size.
Subtract the volume of wood, flowers, stones, or other embedded objects.
For irregular shapes, divide the project into simple rectangles or cylinders and calculate each section separately.
For deep pours, check your resin's maximum pour depth and cast in multiple layers if needed.
Mix only the amount you can pour within the resin's working time.
Warm resin (not hot) flows better and releases bubbles more easily.
Keep your workspace level to prevent resin from pooling.
Double-check all measurements before mixing — epoxy cannot be reused once combined.

Rectangular vs. round: how the math differs
Rectangular & Square Molds
Tables, trays, coasters, panels
Example: a tabletop 600 mm long, 450 mm wide, with a 3 mm resin coating.
600 × 450 × 3 = 810,000 mm³ ≈ 810 mlRound Molds
Trays, clocks, coasters, cylinders
Example: a round tray, 300 mm in diameter, 6 mm deep (radius = 150 mm).
3.14 × 150² × 6 = 423,900 mm³ ≈ 424 mlNote: the result above is the volume of mixed epoxy — resin and hardener combined after mixing, ready to pour. Convert cubic millimeters to milliliters or liters as needed (1 ml = 1,000 mm³).
