What the Microcement Kit 16 m² · floors and stairs · tile contains

This kit renews up to 16 m² of floors and stairs with visible grout lines on glazed surfaces: terrazzo, marble, stone slab, tile, mosaic tile, stoneware or porcelain. It covers the existing floor without lifting it and with no building work.

Its job is to fill and level the grout lines, unify the base and turn an old floor into a continuous surface that stands up to daily use. The finish has more grip underfoot, is easy to clean and withstands the use of rooms such as the living room, the bedroom, the study, the hallway or the playroom.

It is a ready-to-use system, with no tinting and no calculations: a single mix, the varnish with its booster at the end.

To achieve a uniform finish with no marks it is essential to use trowels, rollers and spatulas made specifically for microcement. They are not included in this kit, but you can add the Smartcret tool kit to your order. Tools not tested by Smartcret can affect the final finish.

These are the products included to fully renew your grouted floor of up to 16 m²:

• 2× Smart Jointer (1.5 Kg): for filling and levelling the grout lines, leaving the surface smooth and prepared.
• 2 × Smart Primer PLUS (1 L): maximum-adhesion primer for glazed surfaces such as terrazzo, marble, mosaic tile, porcelain, tile or stone slab.
• 2 × Smart Base (16 Kg): preparation microcement, ready to use and pigmented, intended to even out the surface.
• 1 × Smart Medio (16 Kg): finishing microcement, already coloured, responsible for the final texture with more grip and resistant to wear.
• 2× Smart Varnish (2 L): water-based varnish, matt or satin, that protects against damp, stains and heavy use.
• 2 × Smart Booster (100 g): additive that reinforces the chemical and mechanical resistance of the varnish.
• 12 × Grit 40 discs: for the initial sanding of Smart Jointer and Smart Base.
• 20 × Grit 80 discs: for smoothing the Smart Medio layers.
• 12 × Grit 400 discs: for refining the first varnish layers and achieving a uniform finish.

Key Information before renovating your grouted tile floors using our ready-to-use 16 m² microcement Kit

When the project is bigger, planning matters even more. These tips will help you achieve a flawless, long-lasting finish on your new microcement floor.

🧱 Check the condition of the substrate

Before getting started, make sure your floor is solid and stable:

• There should be no cracks, chips, loose tiles, or damaged areas.
• If you spot any irregularities, repair and level the surface before applying the ready-to-use microcement system.
  

Microcement replicates the surface beneath it. If the substrate has defects, marks or cracks may appear over time. A solid base is the foundation of a perfect result.

👣 Drying, Curing & When You Can Use the Floor

Patience is part of the process:

• The Smart Varnish + Smart Booster mixture has a pot life of approximately 24 hours.
• Do not walk on the floor for 48–72 hours after applying the varnish.
• Allow a full 7 days of curing before using the space normally.

Even if the surface feels dry to the touch, the varnish continues hardening internally.

🪑 Protecting Against Furniture & Dragging

Your new floor is built for everyday life — but a little care goes a long way:

• Do not drag furniture directly across the surface.
• Use protective pads on the legs of chairs, tables, sofas, and stools.
  

Small precautions like these significantly extend the life of the finish.

🧽 Cleaning & Initial Maintenance

During the first 7 days, avoid mopping or using cleaning products.

After that:

• Clean with water and a neutral soap.
• Avoid bleach, ammonia, abrasive cleaners, or metal scrubbers.
• Do not leave standing water for extended periods.

Maintenance is simple — but consistency matters.

🪶 Application: thin Coats & Controlled Sanding

On larger surfaces, consistency is key:

• Apply thin coats following the application guide.

• Respect drying times between layers.
  
• Use the recommended sandpaper grit for each stage.
  
• Hold the trowel at approximately a 45° angle.
  

Even, controlled sanding makes all the difference in the final finish.

⚒️ The right tools = professional results

Microcement-specific tools are essential to avoid marks or surface “burning.”

This kit does not include tools, but you can add the Smartcret tools kit to your order to ensure a smooth, professional finish.

🎯 Final Result

Follow these recommendations, and your new microcement floor will remain seamless, modern, and durable for years — long after that “brand-new” look.

How to apply your ready-to-use microcement kit for grouted tile floors up to 16 m²: step by step (no drama)

If you’re going to transform 16 m², do it right. This isn’t a quick fix — it’s a full-on upgrade. The formula is simple: thin coats, proper drying times, and the right tools. The rest? That’s on you (plus a little attitude).

Here’s your game plan.

1. Prep Work: Floors Don’t Forgive Shortcuts

Before you open the first bucket:

• Sweep and mop thoroughly.
• Remove grease, dust, and everyday buildup.
• Check for cracks or uneven spots.
• If something’s off, fix it now.
  

Microcement won’t hide what’s wrong underneath. It improves it — but it won’t reinvent it. Solid base = top-tier results.

2. Smart Jointer: goodbye grout lines, hello seamless finish

• Fill all the joints.
• Let it dry for 24 hours.
• Sand with 40-grit sandpaper.
• Remove all dust.
  

This is where the first “wow” moment happens. The floor already starts looking different — even before the real transformation kicks in. Let the magic begin.

3. Smart Primer PLUS: make it stick

Terrazzo, marble, tile, porcelain — doesn’t matter. Adhesion matters.

• Apply one even coat with a roller.
• Wait about 30 minutes.
  

This is the handshake between your old floor and your new seamless surface. Skip it, and there’s no story to tell.

4. Smart Base: the real transformation starts

Now we’re getting serious.

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

At this stage, the surface evens out and those grout lines across your 16 m² floor disappear for good. This is no longer “the old floor.”

5. Smart Medio: texture, strength, personality

This is when your floor starts looking magazine-worthy.

• Two thin coats (under 0.5 mm).
• Smart Roller + trowel.
• 6 hours drying time between coats.
• Light sanding with 80-grit between layers.
  

The result? A seamless, modern surface with more grip, built for real life.

6. Varnish + Booster: the final shield

Mix Smart Varnish with Smart Booster and apply:

• 3 coats with a roller.
• 4 hours between coats.
• Light sanding with 400-grit after the first and second coat.
  

Matte or satin — you choose the finish, we deliver the durability. This is where “beautiful” becomes “built to last.”

7. The part everyone forgets: curing time

Yes, you can walk on it carefully after 48–72 hours. But full strength comes after 7 days. That week matters. No aggressive heels. No heroic furniture dragging.

Fully Transformed Space. No demolition. No contractors. No noise. Just a seamless floor no one would guess is hiding terrazzo or marble underneath.

And trust us — that feels a little like magic.
