Naturcem® Low 25L Blue is a water-based acrylic additive specially designed to act as a curing agent and surface hardener in cementitious coatings and decorative mortars. Its characteristic blue color allows for visually controlled application, ensuring uniform product distribution on the treated surface.
Naturcem® Low is indicated to prevent the formation of shrinkage cracks and optimize the progressive drying of the mortar, maintaining the necessary humidity during the critical curing phase. It is compatible with decorative systems such as Naturcem, as well as with multi-layer coatings such as Sttandard or Evoluttion, where it acts as a key part to achieve a uniform, durable and professional final result.

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® Low Blue?
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.
