24 m² microcement kit for tiled kitchen walls

What’s inside the microcement kit for tiled kitchen walls up to 24 m²

Your kitchen walls are ready for a glow-up—and your hands will make it happen. This ready-to-use microcement kit packs everything you need to ditch grout lines and refresh up to 24 m² of tile, mosaic, or porcelain. Quantities are dialed in so you go from bland to modern, durable, on-trend—fast.

• Smart Jointer (3 × 1.5 Kg): Fills grout lines and levels tile relief for a stable, even substrate—the stage where everything else shines.
• Smart Primer PLUS (3 × 1 L): Primer for non-absorbent surfaces (tile, porcelain, mosaic, marble). Delivers reliable adhesion for the microcement system.
• Smart Base (3 × 16 Kg): Pigmented base microcement. Adds body, hides the tile “pattern,” and preps the wall for the finish.
• Smart Liso (2 × 6 Kg + 1 × 3 Kg): Pigmented finish microcement—smooth to the touch and visually seamless.
• Smart Varnish (1 × 5 L): Water-based, high-resistance sealer that stands up to oil, tomato, coffee, and daily splashes. Choose matte or satin to suit your style.
• Smart Booster (1 × 250 g): Additive mixed into the varnish for extra hardness and durability in busy splash zones (near countertops, sink, hob).
• Sandpaper (18 × grit 40 · 30 × grit 220 · 18 × grit 400): For between-coat smoothing.

🧰 Important: Tools aren’t included. For the uniform, pro finish you see in our photos and videos, add the Smartcret Tool Kit (trowel, rollers, spatulas, etc.) to your cart.

Key considerations for coating and caring for your tiled kitchen walls with the 24 m² ready-to-use microcement kit

In the kitchen, walls work as hard as the countertop. Grease, sauce and coffee will try to stick around—your job is to keep them out with a system that’s well applied and well maintained.

1) Splashes: how they behave & what to do

Once sealed with Smart Varnish, the surface withstands typical kitchen splashes for around 8 hours without leaving a trace. Still, best practice is to wipe immediately—the shorter the contact time, the lower the chance of a mark.

Exact agents and times depend on the sealer: check the Smart Varnish datasheet for the list of media and test conditions.

2) Your express daily routine

• Soft, slightly damp cloth.
• Water plus neutral-pH soap diluted in water.

3) Stubborn-stain plan

Use Smart Cleaner (biodegradable) following the product instructions.

4) Always avoid

• Metal scouring pads or stiff brushes → micro-scratches = a less uniform look.
• Bleach, ammonia, strong solvents or strippers → can damage the finish.

Pro tips for a spotless kitchen

• Drying & curing: until the varnish has fully cured, keep cleaning gentle—no chemicals, no heavy scrubbing.
• Preventive care: a quick wipe right after cooking beats a weekend deep clean.

Follow these guidelines and your microcement kitchen walls will stay seamless, hygienic and beautiful over time—even across larger areas.

Application method for the ready-to-use microcement kit for non-absorbent kitchen walls 24 m²

No demolition here—just an upgrade. This ready-to-use microcement kit for non-absorbent kitchen walls lets you refresh up to 24 m² with continuity and control, without builders or dust.

Your kitchen changes vibe without removing a single tile. Work methodically, no rushing. Ideal for DIY over tile, mosaic, porcelain stoneware, or marble.

Goal: swap visible grout lines for a continuous surface that stands up to everyday kitchen life. Let’s go.

1) Quick prep before you start

• Mask off everything you won’t coat (tape, plastic for countertops and floor).
• Clean thoroughly and degrease all non-absorbent wall areas. Tiles, mosaic and porcelain should be spotless.
• Fix any loose or cracked pieces first.

2) Grout gone, flat base in

Fill grout lines and level the surface with Smart Jointer to create a unified wall.

Drying: 24 h · Sand: by hand, grit 40.

3) Full adhesion with Smart Primer PLUS

Load the orange roller and apply a uniform, thin coat of Smart Primer PLUS (for non-absorbent substrates). No blobs, no missed patches. This is the key to strong bonding on tiled, mosaic or marble kitchen walls.

Drying: 30 min—on to the next step.

4) Build your base with Smart Base

Now the love story begins: apply two coats of Smart Base (pigmented base microcement).

• Stir with a spatula.
• Roll out very thin coats (< 1 mm) using Smart Roller for even spread.
• Trowel with the polycarbonate trowel at 45° to level—this helps avoid trowel burn and unwanted marks.
• Between coats: 6 h drying, then hand sand with grit 40 and remove dust.

5) Design feel with Smart Liso

Same tools, new lead: Smart Liso (pigmented finish microcement), two coats.

• Apply very thin coats (< 0.5 mm).
• Control the final look with your pressure and passes.
• Between coats: 6 h drying, hand sand with grit 220, clean off dust.

6) Everyday shield with Smart Varnish

Our system is built to last—now lock it in. Mix Smart Booster with Smart Varnish and let the mix rest 5–15 min. Apply three thin coats on the same day (pot life of the mix: 24 h).

Between coats: wait ~4 h and lightly hand-sand (grit 400) after the 1st and 2nd coats.

Curing & first use

Full cure of the varnish: 7 days. After that, your walls are truly protected—translation: the varnish reaches peak performance from week one.

Pro tips that make a big difference

• Divide and conquer: mark out your working area—24 m² is a generous surface. Stay organised; don’t rush.
• Thin coats = flawless finish. With Smartcret, less is more.
• Keep the 45° rule: that trowel angle delivers a smooth, edge-free surface.
• Gentle sanding: by hand, no heavy pressure—power sanders can overheat and “burn” the material.
• Easy upkeep: water + neutral pH soap; for pro-level care, use Smart Cleaner.
• Respect drying times: it’s the difference between “good” and “wow”.
