What the Microcement kit 24 m² · floors and stairs · tile contains

This kit covers 24 m² of floors and stairs in tile, terrazzo, marble or stone slab, without lifting the existing surface or generating rubble. These are glazed surfaces: the face is closed and does not soak anything up, so the system starts with the primer meant for this case and with filling and levelling the grout lines.

That preliminary step is what sets this kit apart from those built for porous surfaces, and what keeps the pattern of the joints from showing through again over time. It suits living rooms, dining rooms, bedrooms and home offices, and equally the treads of a staircase.

The finish withstands foot traffic, stains, everyday water and ambient humidity, not standing water. The kit contains:

• 3 × Smart Jointer (1.5 kg): for filling and levelling grout lines, leaving the surface smooth and prepared.
• 3 × Smart Primer PLUS (1 L): high-adhesion primer for glazed surfaces such as terrazzo, marble, porcelain, ceramic tiles and stoneware.
• 3 × Smart Base (16 kg): ready-to-use, pre-coloured base microcement for surface preparation and levelling.
• 3 × Smart Medio (8 kg): pre-coloured finishing microcement that provides the final wear-resistant texture with more grip.
• 1 × Smart Varnish (5 L): water-based varnish, available in matte or satin, protecting against moisture, stains and heavy use.
• 1 × Smart Booster (250 g): additive that enhances the chemical and mechanical resistance of the varnish.
• 18 × 40-grit sandpapers: for sanding Smart Jointer and Smart Base layers.
• 30 × 80-grit sandpapers: for smoothing Smart Medio layers.
• 18 × 400-grit sandpapers: for refining the first varnish coats and achieving a flawless finish.

Tools are not included in this kit. To achieve a smooth, consistent finish without marks across 24 m², use trowels, rollers and spatulas made for Smartcret microcement; you can add the tool kit to your order.

Key considerations for a flawless renovation with our ready-to-use 24 m² microcement kit for tiled floors

On larger renovation projects like this one, planning matters just as much — if not more — than application. It’s what makes the difference between a good result… and a truly flawless one.

The following guidelines will help you achieve a smooth, durable and long-lasting finish with your new microcement floor.

🧱 The substrate: the foundation of everything

Before you begin, carefully check the condition of your existing tiled floor:

• No cracks, chips, loose tiles or unstable areas. No damaged or weakened sections.
• If you notice any irregularities, repair and level the surface before applying the system.

Across 24 m², even minor imperfections become visually amplified. Microcement reflects the surface beneath it. A solid, stable base is the key to a uniform finish throughout the entire space.

👣 Drying, curing and floor use

On larger projects, patience isn’t optional:

• The Smart Varnish + Smart Booster mix has a working time of 24 hours. After this, it cannot be used.
• Do not walk on the floor for at least 48–72 hours after applying the varnish.
• Allow a full 7 days of curing before returning the room to normal use.
  

Even if the surface feels dry to the touch, the varnish continues to harden internally. Respecting these times is essential to achieve maximum durability and performance.

🪑 Furniture and foot traffic: protect your investment

Your new floor is designed for everyday life, but proper care prevents unnecessary damage:

• Do not drag furniture directly across the microcement surface.
• Use protective pads on chair, table and sofa legs.
  

In larger spaces, foot traffic is naturally higher. These small precautions significantly extend the life of the finish.

🧽 Cleaning and initial maintenance

During the first week, avoid mopping or using cleaning products, as the varnish is still curing.

After that:

• Clean with water and a pH-neutral soap.
• Avoid bleach, ammonia, abrasive cleaners or metal scouring pads.
• Do not allow standing water to remain on the surface for extended periods, as this may damage the finish.
  

Maintenance is straightforward — but consistency matters.

🪶 Application on large surfaces: thin coats and controlled sanding

On larger areas, consistency is key:

• Apply thin coats following the interactive guide (maximum thicknesses are specified there).
• Respect drying times between layers — rushing leads to problems.
• Use the recommended grit sandpaper at each stage.
• Keep the trowel at a 45° angle.
  

Uniform sanding without excessive pressure — particularly when using electric sanders — is what truly defines the final result.

⚒️ Approved tools matter

Tools specifically designed for microcement application are essential to prevent marks or “burning” on the surface.

This kit does not include tools such as the anti-burn trowel, but you can add the Smartcret tool kit to your order. Using non-approved accessories may compromise the final result (for which we cannot accept responsibility).

🎯 Final result

Follow these recommendations and your new microcement floor will maintain its flawless appearance for many years to come.

Where can you use this 24 m² microcement kit for tiled floors?

This kit is designed for larger spaces where the floor plays a central visual role. It’s ideal when you want to renovate extensive areas in one go, especially over non-absorbent surfaces such as terrazzo, marble, porcelain, stoneware or tiled floors with visible grout lines.

It works particularly well in:

• Large living and dining areas.
• Full office spaces or professional studios.
• Spacious bedrooms, including kids’ and teen rooms.
• Living rooms and playrooms with high foot traffic.
  

The system allows you to cover the entire surface without breaks or transitions, creating a seamless, uniform finish built to handle heavy daily use.

What about bathrooms? It can also be applied to bathroom floors if you’re looking for a slightly more textured finish than Smart Liso (our dedicated system for bathroom flooring).

The result is a modern, grout-free surface that completely transforms larger rooms and maintains its stability and performance over time.

How to apply your 24 m² microcement diy kit for terrazzo or marble floors: step by step (no surprises)

If you’re renovating 24 m², the key isn’t speed — it’s consistency from start to finish. Thin layers, proper drying times and the right tools. The technique stays the same; consistency is what makes the difference.

Here’s the process, no shortcuts.

1. Preparation: on large surfaces, everything shows

Before opening the first container:

• Sweep and clean thoroughly.
• Remove grease, dust and any built-up residue.
• Check for loose tiles, cracks or uneven areas.

Across 24 m², even small imperfections become visible. If something isn’t right, fix it now. The substrate determines the final result.

2. Smart Jointer: level first, build from there

• Fill all grout lines.
• Allow to dry for 24 hours.
• Sand with 40-grit sandpaper.
• Remove all dust.
  

This is where uniformity begins. Grout lines stop dictating the look of the floor and the surface starts to feel cohesive.

3. Smart Primer PLUS: secure adhesion

• Apply one even coat using a roller.
• Wait approximately 30 minutes before continuing.
  

This step ensures proper adhesion over terrazzo, marble or tiled surfaces. On larger areas, consistent bonding is essential.

4. Smart Base: consistency across every metre

• Apply two thin coats (under 1 mm each).
• Spread with the Smart Roller and smooth with the trowel at a 45° angle.
• Allow 6 hours drying time between coats.
• Sand with 40-grit between layers.
  

At this stage, the floor’s overall uniformity is established. Maintain steady pressure and rhythm throughout the space.

5. Smart Medio: texture and durability

• Apply two thin coats (under 0.5 mm each).
• Use roller and trowel as before.
• Allow 6 hours between coats.
• Lightly sand with 80-grit sandpaper.
  

The result is a seamless surface with more grip, designed to handle frequent traffic in larger rooms.

6. Smart Varnish + Booster: full-surface protection

• Mix both components together.
• Apply 3 coats with a roller.
• Wait 4 hours between coats.
• Lightly sand with 400-grit after the first and second coats.
  

This is where the floor gains resistance to stains, moisture and heavy use. Matte or satin — the choice is yours.

7. Curing: patience pays off

• Light foot traffic after 48–72 hours.
• Normal use after 7 days.
  

Across 24 m², respecting curing times is even more important. The system needs this time to reach full hardness and performance.

Fully renewed surface. No demolition. No breaks. No transitions. One continuous plane that completely transforms the room.
