Before you buy

Check if this kit is right for your bathroom

This solution is designed to renovate jointed surfaces (tiles, mosaic, floor tiles…) without removing them. Check these four points before choosing size and colour.

Compatible surface

Surfaces with stable joints: tiles, mosaic, floor tiles, terrazzo or marble. This is not the right kit for plaster, drywall or cement substrates.

Coverage

Measure the height × width of each surface. The calculator adds a 10% margin and recommends the right kit size, or a combination for larger projects.

What's included

Joint filler, primer, microcement base coats, finish, varnish, additive and sandpaper: the complete layer-by-layer system.

What you need separately

Sealer roller, polycarbonate trowel and basic tools. You can find them in microcement tools.

FREE shipping included in the price. Delivery times depend on your country; you will see the estimate at checkout.

Step-by-Step Guide

Everything you need to know before you start

What’s included and what do I need separately?

The kit includes all the Smartcret system products needed for your surface and your square metres: you will find them detailed one by one, with their quantities, in the ‘Description’ tab below. You will also need a sealer roller, a polycarbonate trowel and basic protection and application tools. The microcement comes ready to use, already pigmented; only the final coat of varnish is mixed with its booster.

How do I choose the coverage?

Measure the surface to be covered: for walls, width × height of each section; for floors, worktops or furniture, length × width of each face. Subtract only large openings, add up the total and add a 10% margin. Choose the kit whose m² is equal to or greater than the result; if in doubt between two, go for the larger one. You can also use the calculator in the selector.

How long does the project take?

The full project takes 3 days. The varnish reaches full cure from 7 days.

Can I return or exchange the kit?

Yes: you have 14 days from delivery for exchanges and returns. Return shipping is at the customer’s expense and your order number is enough for us. See the full conditions.

Is it right for my surface?

Each kit is formulated for a specific project and surface: you will find it in the kit name and in the line with ✓ above the coverage selector. If your surface is different (for example, plasterboard instead of tiles), use the assistant at the top and we will take you to the right kit. First repair any loose piece, active crack or damp problem.

Application

The ritual of change: apply the microcement kit for tiled bathroom walls of 8 m² and get ready to be amazed

This is where the wow effect begins. The first step to turning your dull bathroom walls into a finish your whole neighbourhood will want to copy. Trust us. It might seem tricky at first, but you're going to enjoy it—from the process itself to the final result. Ready to let go and get creative? Put some music on and… let’s go!

1. Clean up and wipe the slate clean

Scrub the walls thoroughly and fix any loose bits or chips. Then apply Smart Jointer to fill the joints and level the surface. Let it dry for 24 hours and… voilà! Bye-bye tiles (visually speaking).

2. Get that grip

With Smart Primer PLUS, you make the impossible possible: microcement will stick even to the most stubborn surfaces. One coat, 30 minutes drying time and you're ready to go.

3. Build a solid base

Apply two coats of Smart Base microcement. First with the Smart Roller, then smooth it out with a trowel held at 45°. Let each layer dry for 6 hours, sand with 40 grit, and move on. Your bathroom walls are really starting to transform now.

4. Seamless, timeless beauty

Now it’s time for Smart Liso—the final touch that turns flat into fabulous. Apply two coats, let dry 6 hours between them and sand with 220 grit. The result: a soft, elegant texture that speaks volumes.

5. Seal the masterpiece

Mix Smart Booster with Smart Varnish and protect everything with 3 coats. Go for matte or satin, your call. What’s guaranteed: your newly microcement-coated bathroom wall will resist splashes, stares, and the test of time thanks to the microcement sealer.

🧠 Smart tips:

✔️ Sand by hand, gently. Take your time between coats. Microcement is grateful, but it doesn’t like electric sanders—they can burn the finish.

✔️ Keep your trowel at a 45° angle. That’s the secret to a smooth, continuous surface without surprises.

✔️ Less is more. Thin, even coats work best. Applying too much product can cause cracks.

✔️ Respect the timing. Be patient. The varnish needs 7 full days to reach full strength.

Let the transformation BEGIN

Success stories: how our customers rate Smartcret

4.6/5 ★ (65 reviews on Google)

Christopher Berumen

My wife and I had been looking into microcement for our bathrooms and found Smartcret. Being from the US we worried about importing, but our kits arrived within a couple of weeks. We DIY'd with a contractor friend and LOVE how it came out — smooth, waterproof, and the colours match the catalogue perfectly. If you're in North America, watch for sales to offset shipping costs!

Marcus Sprigens

The solution for revamping a tiled bathroom is Smartcret. Amazing product, very high quality with a smooth to touch finish, a pleasure to walk on in bare feet. No mixing powder and liquid as it comes ready to apply. Super happy with the results and great customer service.

Dee Moe

We used Smartcret for our bathroom walls and it turned out amazing. It was a long process but the steps were easy enough to follow. They were very supportive on WhatsApp and were there every step of the way.

Nicole Lyons

I found this product because I was so sick of cleaning tile grout. I wanted the Tadelakt look without spending $$$. The process takes time but the result was worth it. Only use the plastic trowel — a metal one leaves black marks. The Smartcret team was very helpful. I love my new shower and get so many compliments on it!

I live in the US and ordered from Smartcret. My order arrived within a couple of weeks and the customer service is out of this world! I had an item arrive damaged and they were fast to ship a replacement. Great communication. I'll be doing our shower soon!

Franny Zywicki

We used it in our Hostal for all the bathrooms and floors. We absolutely loved the product — so much quicker as a ready mixed product. Really helpful team. The only tip: use a stronger varnish on your wettest areas.
