1. Deep Clean: the starting point
Say goodbye to grease and dust on your tiles. Fill the grout lines with Smart Jointer until the surface is smooth and even.
⏱ Drying time: 24 hours.
2. First round of adhesion
Apply one coat of Smart Primer PLUS on the non-absorbent surface (tile, marble, mosaic, or porcelain stoneware). This is the secret for everything that follows to bond perfectly.
⏱ Drying time: 30 minutes.
3. Solid base, guaranteed character
With Smart Base, start creating the new skin of your kitchen walls. Apply 2 coats with the Smart Roller and smooth with the trowel at 45°.
⏱ Between coats: 6 hours drying.
🪵 Sand lightly with 40-grit sandpaper and remove the dust before the next coat.
4. Silky moment: the magic of the finish
Give the final touch with 2 coats of Smart Liso. A continuous surface, smooth to the touch and ready to show off. Repeat the process with the same tools.
⏱ Between coats: 6 hours drying.
🪵 Sand very gently with 220-grit sandpaper and remove the dust.
5. Protection for real life
Mix Smart Booster with Smart Varnish and apply 3 thin coats (choose matte or satin).
⏱ Allow 4 hours between coats.
🪵 Sand the first and second coats with 400-grit sandpaper.
⏳ Full curing: 7 days.
🧠 Smartcret Tips for a Perfect Finish
- Trowel always at 45°: the secret angle for a seamless finish.
- Thin coats, no rush: applying too much product can lead to cracks.
- Protect your kitchen: cover countertops, floors, and furniture with plastic before starting.
- Clean quickly: varnish withstands oil or vinegar stains for up to 8 hours, but the sooner you act, the better.
- Be patient: varnish reaches maximum resistance after seven days.
