Consumption per coat0.2 L/m²
Time between coats
- Prepare the substrate by smoothing the fresh concrete to obtain a uniform surface.
- Shake the product before applying.
- Spray with a 0.79 mm nozzle at a pressure between 2 and 4 bars, maintaining a distance of 20 to 40 cm.
- Apply after the bleed water has disappeared, approximately 30 minutes after pouring.
- Allow to act for 3 to 24 hours, adjusting the time according to temperature and wind.
- Wash with pressure water (100–150 bars) at a 45° angle, removing the surface laitance and exposing the aggregate.

Frequently asked questions about Naturcem
What is Naturcem® and what is it used for?
It is a water-based surface retarder for concrete. It delays the setting of the cement in the surface layer so that, after washing it off, the aggregate is exposed and you get a decorative finish with a natural, non-slip texture.
What is the difference between Naturcem® Low, Medium and High?
The etching grade changes with the aggregate size: Low (blue) grade 2 for 5-8 mm aggregates, Medium (pink) grade 4 for 10-14 mm and High (yellow) grade 5 for 14-18 mm. We recommend a test on site to adjust the depth.
Where can I use Naturcem®?
It is designed for decorative concrete paving, such as urban areas, pavements and outdoor surfaces, as well as street furniture and exposed-aggregate coatings.
How is Naturcem® applied?
It comes ready to use: shake it and spray it evenly onto the smoothed fresh concrete once the bleed water has disappeared (about 30 minutes after pouring), with a 0.79 mm nozzle at 2-4 bar. Avoid puddles and thick coats.
When and how is the surface washed to reveal the aggregate?
Between 3 and 24 hours after applying it, depending on temperature, sun and wind, wash with pressure water (100-150 bar) from 20-40 cm and at a 45° angle to remove the surface laitance.
Do I need to protect the surrounding areas, and in what conditions can I apply it?
It is biodegradable and solvent-free, and there is no need to protect the surroundings except painted façades and porous surfaces. Apply it with air and substrate temperatures between 5 °C and 30 °C and without excessive wind; the equipment is cleaned with water.
What is the coverage of Naturcem® High Yellow?
Approximately 0.2 L/m² per coat; 2 coats are recommended. Actual consumption depends on the substrate and application. Use the calculator above to work out how much you need.
