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 15 days from receipt for exchanges and returns. Return shipping is at the customer’s expense and you will need the invoice to process it. 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.

Description

What’s included in this microcement kit to transform bathroom floors with joints up to 24 m²?

Everything you need to say goodbye to visible joints in a generously sized bathroom. No weird tools involved. A single mix — the varnish with its enhancer at the end.

- 3 units of Smart Jointer (1.5 Kg each): quick-drying, super-adhesive filler perfect for covering joints in ceramic, marble or mosaic surfaces.

- 3 units of Smart Primer PLUS (1 L each): water-based primer that preps the surface and ensures perfect grip of the microcement on non-absorbent and low-porosity substrates.

- 3 units of Smart Base (16 Kg each): pigmented, ready-to-use base microcement with extra thickness to build a solid foundation.

- 2 units of Smart Liso (6 Kg) and 1 unit of Smart Liso (3 Kg): ready-to-use finishing microcement, pre-coloured and smooth for a professional look and feel.

- 1 unit of Smart Varnish (5L): protective varnish that shields against moisture, friction and cleaning products. Available in matte or satin finish.

- 1 unit of Smart Booster (250 g): added to the varnish for extra durability and resistance to wear.

- Included sanding discs: 18 discs of 40 grit, 30 discs of 220 grit, and 18 discs of 400 grit—for perfect results layer by layer.

And the tools? Sold separately. We recommend our dedicated tool kit including a heat-resistant polycarbonate trowel, rollers, trays and protective tape. Everything you need—no guesswork. Using non-recommended tools could ruin your precious microcement (and let’s be honest, you didn’t dive into your first DIY makeover for that).

Application

How to apply your microcement kit for bathroom floors with joints (24 m²) – no pros needed

Tackling a big bathroom might seem like a challenge, but with this step-by-step guide (and your renovation drive + our helpful tips), you'll do it without breaking a sweat.

1. Clean and prep like a pro

Remove dirt, grease or soap residue. Once dry, tape off the areas you don’t want to cover.

2. Say goodbye to joints

Use a trowel or spatula to apply Smart Jointer to all joints. Let it dry for 24 h and sand with 40-grit paper. The smoother, the better.

3. Prime with style

Apply Smart Primer PLUS using a roller. It dries in just 30 minutes and preps the surface for the microcement.

4. Go big with the base

Using the Smart Roller, apply a thin layer (<1 mm) of Smart Base. Smooth with the polycarbonate trowel using gentle strokes. Repeat for a second coat, allowing 6 h between coats and sanding each with 40-grit paper.

5. Smart finish

Now it’s Smart Liso’s turn. Same method: thin layer, smooth it out, sand with 220-grit paper, wait 6 h between coats. After the second coat, wait 24 h before moving to the final step.

6. Seal and protect

Mix Smart Varnish with Smart Booster, shake gently, and let sit for 10 min. Mask edges with tape and apply 3 coats, letting each dry for 4 h. Sand the first two with 400-grit paper. After 7 days: fully sealed and ready to shine.

*Important: Always apply with the Smartcret trowel at a 45° angle. Avoid using electric sanders—they might damage or burn the surface due to excess pressure.

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!

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.

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.

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 had an amazing experience with Smartcret, absolutely amazing for beginners like me. I changed the floor in a beautiful small cabin and the change was incredible. The service was wonderful. Highly recommend!

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!

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.
