What Is Microcement?
Definition
Microcement is a thin, cement-based surface system applied by trowel in multiple layers to create a continuous, seamless finish.
Unlike traditional concrete, microcement:
- Is applied at 2–3 mm thickness
- Bonds to existing surfaces
- Does not require demolition
- Creates a joint-free appearance
Microcement is not a single product — it’s a category of systems with very different performance characteristics.
Where Microcement Is Used
Microcement is commonly used on:
- Floors
- Walls
- Bathrooms & showers
- Countertops
- Stairs
- Furniture and architectural elements
Its appeal comes from its:
- Seamless look
- Modern aesthetic
- Adaptability to existing substrates
What Microcement Is Made Of
Most microcement systems include:
- Cement
- Fine aggregates
- Polymers or resins
- Additives for workability and adhesion
- Sealers for protection
The exact formulation matters — especially for:
- Durability
- Crack resistance
- Water resistance
- Ease of application
This is where systems differ significantly.
The Biggest Misconception About Microcement
Microcement is not one material.
There are:
- Highly technical professional systems
- Modern premixed systems designed to simplify installation
Both can produce beautiful results — but they are not interchangeable.
Pros of Microcement
- Seamless, joint-free finish
- Can be applied over existing surfaces
- Minimal thickness
- Modern, architectural appearance
- Customizable textures and colors
Limitations & Considerations
Microcement is not “maintenance-free” or “fail-proof.”
Important considerations:
- Substrate preparation is critical
- Cracking can occur if systems are misused
- Waterproofing depends on system + sealer
- Some systems are unforgiving to DIY errors
Understanding these limits is essential to success.
Is Microcement Right for You?
Microcement can be an excellent solution — when the right system is chosen and applied correctly.

How thick is microcement?
Microcement is typically applied at 2–3 mm thick, making it ideal for renovations where floor height and transitions matter.
Is microcement waterproof?
Microcement itself is not waterproof, but when sealed correctly, it becomes water-resistant and suitable for wet areas like bathrooms and showers.
Does microcement crack?
Microcement can crack if the substrate moves, preparation is poor, or the system is improperly applied. Proper system choice and preparation greatly reduce this risk.
