Micro-concrete and concrete sound similar, but they behave completely differently in furniture. If you're choosing a table, stool, or lamp, here's a clear comparison that will show you why the material matters.
Quick Answer
Concrete is a massive cast material. Micro-concrete is a thin cement layer applied to a solid core and sealed. The result: a micro-concrete piece looks like stone, but it's 70% lighter and doesn't tend to crack in its mass like cast concrete.
Point-by-Point Comparison
| Property | Cast Concrete | Micro-concrete |
|---|---|---|
| Construction | solid cast block | thin layer on a core |
| Weight | high | 70% lower |
| Cracking | tendency to crack in mass | does not crack like a solid block |
| Surface | rougher, porous | smooth, seamless, stone-like |
| Handling | heavy, often two people | can be carried with one hand |
| Stain resistance | impregnation necessary | two layers of mineral impregnation |
| Suitable for | exterior, massive elements | designer interior furniture |
Why Micro-concrete is Lighter
Concrete carries its entire weight: it's a solid piece of material. Micro-concrete is applied only as a surface layer on a light core, so the vast majority of the volume is made up of a lighter structure, not heavy mass. That's why a table that looks like solid stone can be lifted with one hand.
Why Micro-concrete Doesn't Crack
Massive concrete reacts to temperature changes and internal stresses, and can crack in its mass. The micro-concrete layer is thin and flexible, adhering to a stable core, and does not react to temperature changes in the same way. Slight variations in shade and surface texture are not cracks, but a natural characteristic of a handmade material.
When to Choose Which
Cast concrete makes sense where you need a massive, load-bearing, or outdoor element and weight is not an issue. Micro-concrete, on the other hand, is designed for interior designer furniture: a stone look without the weight and fragility, for an apartment that is occasionally rearranged.
Maintenance: Almost the Same, but Easier
Both materials appreciate gentle cleaning and occasional impregnation. However, with micro-concrete, it's easier due to the smooth, sealed surface: a soft damp cloth, a gentle cleaner, no abrasives. Details in the Care and Maintenance guide.
Frequently Asked Questions
Is micro-concrete the same as concrete?
No. Micro-concrete is a thin cement layer on a core, while concrete is a solid cast block. Micro-concrete is therefore lighter and more dimensionally stable.
Is micro-concrete as durable as concrete?
For interior furniture, yes. The sealed surface is hard and waterproof, and unlike massive concrete, it doesn't tend to crack in its mass.
Is micro-concrete furniture heavy?
No. It's 70% lighter than solid concrete of a similar size; a common table can be moved with one hand.
