Performance
Specification data
Values from the published Terrazzino Specification sheet snapshot (no revision date). [NEEDS DATA: confirm current TDS revision and whether values apply to the Terrazzino layer or the complete system.]
At a glance
Compressive strength
10,500 psi
Stronger in compression than the concrete slab beneath it.
Tensile strength
6,300 psi
Resists being pulled apart under load.
Hardness
Shore D 82 (typical)
A hard, rigid wear surface.

< 2 g/L
Very low off-gassing during and after installation.
Gloss
> 70 at 60°
A high-gloss finish at 60° sheen.
In context
How it compares
Reference figures for context, not a head-to-head lab test.
Comparison figures come from different documents and, for concrete, a different test method (ASTM C39 cylinders vs ASTM D695 for resins). They are indicative context, not a head-to-head test.
| Terrazzino | 10,500 |
|---|---|
| Residential concrete (typical) | 2,500 |
| Commercial concrete (typical, and higher) | 4,000 |
| NTMA epoxy terrazzo resin — minimum | 10,000 |
Far stronger in compression than the concrete slab it sits on — the floor won't be the weak link under rolling loads or furniture.
| Terrazzino | 6,300 |
|---|---|
| NTMA epoxy terrazzo resin — minimum | 3,000 |
Resists being pulled apart — about twice the minimum the terrazzo industry asks of its epoxy resins.
| Terrazzino | 82 |
|---|---|
| NTMA epoxy terrazzo resin — range | 60–85 |
A hard, rigid surface — near the top of the range specified for epoxy terrazzo resins.
| Terrazzino | 350 |
|---|---|
| NTMA epoxy terrazzo bond strength | 300 |
Bonds more strongly than the concrete itself — in the test, the concrete broke before the coating let go.
8,300 psi
Can flex under load without cracking (no NTMA minimum is published for flexural strength).
