Frequently Asked Questions About Microcement​

​

Microcement is a seamless decorative coating used to create modern finishes on walls, floors, bathrooms, showers, kitchens, commercial spaces, and other interior surfaces. Because microcement is applied as a complete multi-layer system, the quality of the finished surface depends on proper preparation, reinforcement, application, and sealing.

Below you will find answers to the most common questions about microcement installation, durability, waterproofing, maintenance, colors, thickness, and suitable surfaces.

​

🚿 Can Microcement Be Used in Showers?

Yes. Microcement can be used on shower walls and shower floors when it is installed as a complete waterproof system.

The surface must be stable, properly prepared, and protected from moisture before the decorative microcement layers are applied. Depending on the project, the installation may include a waterproof membrane, primer, fiberglass mesh, reinforcing base coats, finish coats, and a professional protective sealer.

The final protective coating is especially important in showers because it helps prevent water, soap, and cleaning products from penetrating the decorative surface.

Microcement itself should not be treated as a substitute for proper waterproofing behind the finish. The waterproofing system and the decorative coating must work together.

​

💧 Is Microcement Waterproof?

A properly installed and sealed microcement system can provide a highly water-resistant surface suitable for bathrooms, showers, kitchens, and other areas exposed to moisture.

However, the finished system is only as reliable as the surface preparation, waterproofing, application, and sealer used during installation.

Microcement should always be protected with the appropriate professional sealer. In wet areas, additional waterproofing beneath the microcement may also be required.

For this reason, microcement should be viewed as a complete system rather than a single decorative coating.

​

🧱 Can Microcement Be Applied Over Existing Tile?

Yes. In many cases, microcement can be applied directly over existing ceramic or porcelain tile without removing the tile.

The existing surface must be firmly attached, clean, dry, and free from movement. Loose tiles, cracked grout lines, grease, soap residue, and unstable areas must be repaired before installation.

The surface is then prepared with the appropriate bonding primer. Grout lines may need to be filled and leveled, and reinforcing mesh may be used to reduce the possibility of the tile pattern or joints becoming visible through the finished surface.

Applying microcement over tile can save demolition time and create a seamless new finish with minimal additional thickness.

​

📏 How Thick Is Microcement?

A typical microcement finish is only a few millimeters thick.

The exact thickness depends on the substrate, the number of base and finish coats, reinforcement requirements, and the specific system being installed.

Because microcement is applied in thin layers, it can often be installed over existing surfaces without significantly changing floor levels, door clearances, or room dimensions.

Its low thickness is one of the main reasons microcement is popular for renovations.

​

🏠 Where Can Microcement Be Used?

Microcement can be used on many interior surfaces, including:

• Walls

• Floors

• Bathrooms

• Showers

• Kitchens

• Backsplashes

• Fireplace surrounds

• Staircases

• Accent walls

• Retail spaces

• Restaurants

• Hotels

• Offices

The surface must be stable and properly prepared for the intended use. Floors, showers, countertops, and high-traffic commercial areas require a stronger protective system than ordinary decorative walls.

​

🎨 Can Microcement Be Made in Different Colors?

Yes. Microcement can be produced in a wide range of colors, including warm neutrals, cool grays, natural stone tones, concrete colors, beige, white, charcoal, and custom decorative shades.

The final appearance can also change depending on the application technique, lighting, sanding, movement of the trowel, and protective sealer.

Because microcement is applied by hand, every finished surface has natural variation. This gives the material its distinctive character and makes each installation unique.

​

🪨 Does Microcement Look Like Concrete?

Microcement can create a modern concrete-style appearance, but it offers more design flexibility than traditional poured concrete.

The finish can be smooth, softly textured, cloudy, industrial, natural, or more uniform depending on the application technique.

Unlike thick concrete slabs, microcement is applied in thin decorative layers. It can therefore create the appearance of concrete on existing walls, floors, tile, and other properly prepared surfaces.

​

🔨 Can Microcement Crack?

Microcement is designed to create a strong and durable decorative surface, but it cannot stop structural movement underneath it.

Cracking may occur if the substrate is unstable, incorrectly prepared, already cracked, flexible, or subject to excessive movement.

Proper surface preparation, repair of existing cracks, reinforcement with fiberglass mesh, correct application thickness, drying time, and professional sealing all help reduce the risk of cracking.

Microcement should never be applied over a weak or moving surface without correcting the underlying problem first.

​

🧼 How Do You Clean Microcement?

Microcement surfaces should normally be cleaned with water and a mild, non-abrasive cleaner.

Avoid harsh chemicals, aggressive solvents, abrasive powders, steel wool, and rough cleaning pads because they may damage or dull the protective sealer.

Spills should be cleaned promptly, especially on floors, countertops, and other frequently used surfaces.

The correct maintenance routine depends on the type of sealer and the location of the installation.

​

⏳ How Long Does Microcement Last?

A professionally installed and properly maintained microcement surface can last for many years.

Its lifespan depends on several factors:

• Condition of the original surface

• Quality of surface preparation

• Correct use of primer and reinforcement

• Number and thickness of the applied coats

• Type of protective sealer

• Level of foot traffic or moisture exposure

• Cleaning and maintenance

High-traffic floors and wet areas may eventually require maintenance or renewal of the protective topcoat. The decorative microcement layers beneath it can remain in good condition when the system is properly cared for.
