How to Use This Calculator
- Enter the total floor area and room dimensions in square feet and feet.
- Set the terrazzo layer thickness in inches (1/4 to 3/8 inch for epoxy, 1/2 to 5/8 inch for cementitious).
- Enter the divider strip grid spacing in feet.
- Set the aggregate-to-binder ratio percentage.
- Review the mix volume, divider strip linear footage, and estimated material quantities.
How the result changes with Floor area
| Floor area | Aggregate needed | Binder (epoxy/cement) |
|---|---|---|
| 10,009 | 29,193 lbs | 936 gal |
| 35,007 | 102,104 lbs | 3,274 gal |
| 65,004 | 189,595 lbs | 6,078 gal |
| 90,001 | 262,503 lbs | 8,416 gal |
What each input means
- Floor area
- Total area to receive terrazzo.
- Room length
- Length of the room (for divider strip grid).
- Room width
- Width of the room (for divider strip grid).
- Terrazzo thickness
- Depth of terrazzo layer. Epoxy: 1/4"-3/8", cementitious: 1/2"-5/8".
- Divider spacing
- Grid spacing between divider strips (typically 3-6 ft).
- Aggregate ratio
- Percentage of aggregate in the mix (typically 70%).
What each result means
- Aggregate needed
- Weight of marble, glass, or stone aggregate chips.
- Aggregate (tons)
- Aggregate weight in US tons.
- Binder (epoxy/cement)
- Gallons of epoxy or cementitious binder.
- Divider strips
- Total linear feet of zinc or brass divider strips.
- Sealer
- Gallons of terrazzo sealer (2 coats at 350 sq ft/gal).
- Total mix volume
- Total volume of terrazzo material.
