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 the microcement kit for bathroom floors with joints for 8 m²?

You were born with a DIY spirit, but now you’ve fallen for the charm of ready-to-use microcement — and you're about to tackle your first no-reno makeover.

Turning a joint-filled floor into a smooth, modern surface is easier than you think. With the right materials, it's a piece of cake! And at Smartcret, we make it easy for you to forget about mess or stress. A single mix — the varnish with its enhancer at the end. Just apply… and enjoy the ride.

Curious about the products behind the big transformation you’re about to pull off? Here’s what’s included in our microcement kit for bathroom floors with joints for 8 m²:

- 1 unit of Smart Jointer (1.5 Kg): a high-adhesion, fast-drying filler paste used to fill and smooth joints between tiles and mosaics. Its main job is to level the surface before applying Smartcret’s ready-to-use microcement. It’s also resistant to water and ambient humidity.

- 1 unit of Smart Primer PLUS (1L): a water-based acrylic primer that improves the adhesion of Smartcret microcement on non-absorbent surfaces such as tiles, mosaics, terrazzo, marble, etc.

- 1 unit of Smart Base (16 Kg): a ready-to-use coloured preparation microcement with strong adhesion and a coarser grain. It’s applied as the base layer before using Smart Liso.

- 1 unit of Smart Liso (6 Kg): a ready-to-use coloured finishing microcement with a finer grain and strong adhesion. It’s the final layer of the Smartcret system and can create burnished or water-like effects during application.

- 1 unit of Smart Varnish (2L): a water-based varnish that protects microcement from abrasion, cleaning agents, moisture, and daily wear. It enhances colour and is available in matte or satin finish.

- 1 unit of Smart Booster (100 g): component B added to the varnish for increased chemical resistance, hardness and durability against abrasion.

- Sanding discs: to sand between layers during the microcement application. Includes 6 discs of grit 40, 10 discs of grit 220 and 6 discs of grit 400.

At Smartcret, we also offer a separate tool kit specifically for applying our microcement. It’s not included in this microcement kit for bathroom floors with joints up to 8 m², but we highly recommend it for optimal results. It includes tools such as rollers, polycarbonate trowel, paint trays, protective masking tape, and more.

Application

How to apply the microcement kit for bathroom floors with joints for 8m2

1. Before starting, clean and degrease the surface.Once it’s dry, mask off the area with protective tape.

2. Fill the joints using a spatula or trowel with one coat of Smart Jointer. Let it dry for 24 hours. Then sand the surface with 40-grit sandpaper.

3. Prepare the surface for the system. Use a roller to apply one coat of Smart Primer PLUS. Let it dry for 30 minutes.

4. Dip the Smart Roller into Smart Base and spread a thin coat (less than 1 mm) vertically, then horizontally across the surface. Smooth it out with the polycarbonate trowel using arched movements in all directions. Repeat the process until the entire surface is evenly covered and smooth. Let each coat dry for 6 hours and sand between coats with 40-grit sandpaper. Apply 2 coats of Smart Base in total.

5. Repeat the same process with Smart Liso.Use the Smart Roller and polycarbonate trowel to apply a thin coat (less than 0.5 mm) until the surface is fully covered. Allow 6 hours of drying between coats and sand with 220-grit paper after each one. Remove the masking tape between coats. Apply 2 coats of Smart Liso in total. Let dry for 24 hours after the final coat.

6. Add Smart Booster to the Smart Varnish container.Shake the mix gently by hand for a few minutes. While it rests, apply masking tape to the necessary areas. Let it sit for 5–10 minutes.

7. Once the Smart Varnish mix is ready, apply the first coat. The mix remains usable for 24 hours, so you can apply the second and third coats within that time. Allow each coat to dry for 4 hours. Once the final coat is dry, remove the masking tape. Don’t forget to sand the first and second coats with 400-grit sandpaper. Keep in mind: the varnish will reach maximum resistance after seven days.

*Important: Maintaining a 45º angle with the trowel is key when applying Smartcret microcement. Otherwise, the final result may not turn out as expected. It's also essential to use the Smartcret polycarbonate trowel — it's burn-resistant! Using a different type of trowel could affect the finish. Keep in mind that the sanding sheets included in the kit are designed for manual sanding. Using an electric sander may apply too much pressure and damage or burn the surface.

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.

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.
