What is a microcement table actually made of?
From the outside, a microcement table looks like a perfect, seamless, almost sculptural mineral block. But if we were to cut it in half, we would discover that its construction is far more sophisticated.
Understanding what’s inside the table helps alleviate concerns (weight, stability) and also appreciates why not all microcement tables are the same.
The structural core: the invisible foundation
Most high-quality microcement tables have a structural core that provides shape, rigidity, and weight control.
Depending on the design, this core can be made of high-density fiberboard or structural plywood. In some cases, internal metal reinforcements are used for large overhangs or very long meeting tables.
The function of this core is to:
- Ensure that the table does not flex or vibrate with daily use.
- Allow for customization of dimensions (length, width, tabletop thickness, leg shape) without making the piece excessively heavy.
At CimentStudio, for example, many tables are designed precisely like this: a custom-made structure upon which the microcement “cover” is built.
Microcement layers: texture and resistance
The microcement system is applied over this core in several layers:
Adherent layer/bonding layer: Ensures adhesion between the substrate and the microcement.
Base layers (1–2 layers): Provide thickness and continuity. They allow for the correction of minor imperfections, rounding of edges, and definition of corners.
Finish layers (1–2 layers): Provide the visible texture, color nuance, and characteristic “movement” of microcement.
In furniture, a balance between a soft feel and a mineral character is sought.
In total, we are talking about 3–4 layers of microcement, depending on the desired finish. The total thickness is relatively small, but sufficient to give a sense of mass and solidity and ensure good resistance to scratching and wear in domestic or office use.
Sealing and varnishing: the skin that protects everything
The last, but certainly not least, part is the sealing system: Typically, two coats of polyurethane varnish specifically designed for microcement are applied. This varnish offers very low porosity and good chemical resistance.
It acts as an invisible barrier against stains, liquids, and dirt.
This is where a significant difference is made between a table that looks “pretty in photos” but is delicate, and a table designed for heavy daily use, capable of holding its own in a dining room, open-plan kitchen, or meeting room.
A good varnish system reduces absorption, makes cleaning very easy, and allows the table to regain its original appearance with a light professional touch-up after several years.
And the weight? Is it like having a block of concrete in the living room?
It’s a very common question: “How much does this weigh? Will I be able to move it if I rearrange it?”
With an optimized core and controlled microcement thickness, the weight is usually much less than what we imagine when we think of “cement”: It’s more in the same league as a quality solid wood table than a concrete block.
For very large tables or special projects, you can play with apparent thicknesses (visually thicker edges but lighter on the inside), T-shaped or U-shaped structures that distribute the weight better.
The important thing is that the table is well-designed from the start: that’s where the craftsmanship and the workshop’s experience come in.
