How to apply the microcement kit for bathroom floors with joints like a pro for 16 m²

Got more square metres and more motivation? Perfect. Here’s how to turn 16 m² of annoying joints into a sleek, seamless surface. Ready? Let’s do this!

1. Start fresh: clean & protect

Clean the surface of dust, grease, and soap. Once dry, tape off the area to protect the edges. No surprises, no drama.

2. Joints, be gone with Smart Jointer

Use a trowel or spatula to fill every joint with Smart Jointer. Let it dry 24 h, then sand with 40-grit sandpaper. Bonus points if it’s smooth as a surfboard.

3. Prime for perfect grip

Roll on one layer of Smart Primer PLUS. This water-based primer ensures your microcement sticks like a pro. Dry time? 30 minutes—just enough for a coffee.

4. Build the base with Smart Base

Roll on a thin coat (<1 mm) vertically, then horizontally. Smooth with the polycarbonate trowel in gentle, sweeping motions. Apply two coats, letting each dry 6 h and sanding with 40 grit in between.

5. Finish strong with Smart Liso

Same steps, new product. Apply thin coats of Smart Liso, sanding between with 220 grit. Two coats total. Wait 24 h after the last one. Your bathroom’s already looking stylish!

6. Mix, shake, seal: Smart Varnish + Booster

Add Smart Booster to the varnish, shake gently and let it sit 5–10 minutes. Tape the edges. It’s like locking in your masterpiece.

7. Three layers of full-on protection

Apply the first coat, dry 4 h, sand with 400 grit. Repeat twice. Remember: varnish has a 24 h life. After 7 days, your floor will be ready for anything.

Important: keep your Smartcret trowel at a 45º angle. Only use Smartcret’s recommended tools. Manual sanding only—an electric sander could burn your finish.
