8/ OTHER MEDIA

• Cellular concrete
• Gypsum wallboard (excluding floor)
• Cement slabs
• Bricks
• Breeze blocks
• Wood derivative (chipboard, medium, plywood, etc.)

Precautions

Colors and blends

To guarantee shade homogeneity, use the same component A batch number and the same Blush Concentré Couleur Minérale batch number for the same job.

Mineral Color Concentrate Blushes contain pigments, fillers and additives in different proportions to achieve a constant rheology (fluidity and consistency) of the final product. It is strictly forbidden to mix concentrates together.

Béton Ciré Classic bases are semi-finished materials. It is essential to add a concentrate to ensure that the properties of Classic Micro Concrete are fully preserved and the formula is stable. Even in white, the addition of a white Mineral Color Concentrate Blush is mandatory. Using the base alone without adding the concentrate alters the nature of the product and reduces the system’s chemical and mechanical performance.

The product must be used by strictly mixing the 3 components.

Never add water.

Uses

Sauna and hammam applications are excluded.

Do not apply to solid wood, softwood floors, plastics and textiles, unglazed terracotta, terracotta tiles and Fermacel fibre-gypsum boards.

Storage and safety

1 year in original, unopened packaging, out of direct sunlight and frost, at temperatures between +5° and 25°C, ideally between 15 and 20°C. Check the expiration date on the packaging before use. Once opened, the product must be used within 7 days.

Use appropriate personal safety equipment as described in Safety Data Sheets.

For further safety information, please consult the Safety Data Sheet.

Mixture preparation

Preparation is carried out using dry mixing (for multiple use of the kit) or wet mixing (for complete use of the kit).

Dry mixing

In the case of dry mixing, always mix base and concentrate in their entirety before dividing.

• Roll the base bucket to aerate and soften the material
• Open the base bucket and make a slight indentation in the center of the base.
• Shake and open the jar of concentrate
• Pour concentrate into center of base bucket
• Block the bucket with the feet and mix the base and concentrate (ideally with a mixer for pasty products; please consult us for prices).
• Immerse the mixer and gradually increase the speed.
• Continue mixing with straight and angled vertical and lateral movements to perfectly blend the contents. Insist on the edges at the bottom of the jar, so as not to forget those corners that are most difficult to mix. When mixing for the first time, we recommend pouring the mixed contents into a bucket of the same size, to visually check the quality of the mix and repeat if necessary. Mixing time must not be less than 1 minute
• Add component B (liquid) to the quantity of powder prepared: base (component A) + Blush Concentré Couleur Minérale perfectly mixed according to the table below:

Note: the shelf life of dry-mixed materials is not affected by mixing if the buckets (base + concentrate) are closed and stored under normal conditions.

Wet mix

• Pour the liquid part (component B, 5.32kg) into a clean, empty bucket
• Shake and open the jar of Blush Concentré Couleur Minérale
• Pour Blush Concentré Couleur Minérale into the liquid
• Block the bucket and mix at progressive speed until the liquid and concentrate are homogeneous.
• Add the powder (Component A) to the liquid.
• Mix mechanically for 2-3 minutes until homogeneous.

Never add water.

Implementation

Hydrometry

The Marius Aurenti Micro Concrete System should be applied at a relative ambient humidity of between 30% and 80%, except for varnishes which require a humidity range above 40% and below 80%, ideally between 50% and 65%.

Moisture conditions must be maintained for at least 48 hours after application of the last coat.

Protect from wind, direct sunlight, rain, frost and environmental influences during application and curing.

Before any application, check the moisture content of the substrate (maximum 4% moisture content and ≤0.5% for calcium sulfate-based fluid screeds).

Temperature

Before starting any application, it is essential to check the substrate and ambient temperatures. Substrate temperature must be between +5°C and +25°C (ideal temperature: > 15°C and 20°C).

It must be at least 3°C higher than the temperature corresponding to the dew point.

The Marius Aurenti micro concrete System can be applied at ambient temperatures between 5°C and 25°C for the micro concrete and between 15°C and 25°C for the varnishes, at least 24 hours before the first application and at least 24 hours after application of the last coat.

Low and high temperatures will respectively slow down and speed up setting. Do not apply in frosty or hot weather. Provide heating or cooling systems if necessary.

Application material

Smoothing trowel, 6 mm notched comb, triangular notch, (first coat only).

Parfait’Liss 35 cm or 200 mm stainless steel or plastic smoother.

Sponge float or mason’s sponge (dry) for a non-slip finish.

Clean tools with water.

Apply a first coat and, if necessary, a second coat of Ultra Fine micro concrete in a thin layer. These finishing coats determine the final grain of the coating and smooth it out. These coats are applied with a smoothing trowel in the same direction as the coats of Classic micro concrete or Fluid micro concrete.

It’s important to note that a stainless steel application tool can leave dark marks (especially on light colors). A plastic tool may be preferred.

After 24 hours drying time (at 20°C), sand the surface (grit 80 then 100 then 120) using an orbital sander (or a single-brush sander for floors), then dust using a vacuum cleaner.

Corners should be sanded by hand. The intensity of the sanding will finalize the surface appearance (grained or smooth) and bring out the material effects. If the surface is deemed satisfactory and compliant, proceed with the application of the protective coatings.

4 possible protections (refer to the Technical Data Sheets for these products) :

Interior protection:

• IF3 fixative
• Porous filler n°5 + varnish N°7 (combined use is mandatory to avoid whitening)

Exterior protection :

• Impregnation Terrace n°2

Consumption

Drying time at 20°C and 60% relative humidity

Commissioning

The surface must not be exposed to the full range of stresses until the treatment system has fully dried, i.e. 7 days at 20°C and 60% relative humidity.

Between 2 days and 7 days, light traffic can be allowed, with the following precautions: microbreathable protective tarpaulins such as Landolt’s Floorliner Vapor, traffic in socks or overshoes. No exposure to water or chemical agents, no rubbing or scratching of furniture. It is forbidden to apply adhesives to coverings.

Do not lay carpet for 7 days.

VERY IMPORTANT NOTE:

• The maximum hardness of the Marius Aurenti Micro Concrete System is achieved after 28 days of drying.
• The floor must be handed over immediately after completion of the work. The freshly applied Marius Aurenti System must be protected from the work of other trades by protective materials that allow aeration (see Varnish n°7 Visco and Fixative IF3 Technical Data Sheet).
• Delay before first wet maintenance: 3 days minimum after application of Varnish n°7 or IF3 Fixative.

Precautions and prohibitions

To guarantee uniformity of shade, use the same batch number for A components and the same batch number for color concentrates (Local mix) on the same job site.

Local mixes contain pigments, fillers and additives in different proportions to achieve a constant rheology (fluidity and consistency) of the final product.

It is strictly forbidden to mix concentrates together.

Local mixes are semi-finished materials. It is essential to add a concentrate to ensure that the properties of the micro concrete are integral and the formula stable. Even in white, the addition of a white concentrate in the corresponding color is mandatory.

Using the base alone without adding the concentrate (local mix) alters the nature of the product and reduces the system’s chemical and mechanical performance.

The product must be used by strictly mixing the 3 components. Never add water.

Application material

Smoothing trowel6 mm serrated triangular trowel.

Parfait’Liss 35 cm smoothing machine or equivalent.

Béton Ciré Marius Aurenti is a two-component mortar applied 2 mm thick.

Apply a first coat of micro concrete at a consumption of approx. 3 kg/m² (approx. 1.5 mm thick) using a trowel. To regulate thickness, the first coat can be applied with a 6 mm notched comb, then immediately smoothed with a smoothing trowel until the ridges on the notched comb disappear completely. In this case, smoothing must be carried out without delay, in the fresh micro concrete.

This first layer determines the final thickness and aesthetic effects.

Before applying the second coat and 24 hours after applying the first (at 20°C, 60% relative humidity), you can sand the surface (40 grit) using a single-brush machine (or orbital sander), then remove all dust mechanically.
Apply the second coat at a rate of approximately 1kg/m², using a trowel, then smooth.

This second layer determines the final grain of the coating.

It’s important to note that a stainless steel application tool can leave dark marks (especially on light colors). A plastic tool may be preferred.

After 24 hours drying time (at 20°C, 60% relative humidity), sand the surface (60-grit then 80-grit) using a single-brush machine (or orbital sander), then remove all dust mechanically.

The intensity of the sanding will finalize the surface appearance (grained or smooth) and bring out the material effects. If the surface is found to be in conformity, proceed with the application of finishes.

FULL DRYING: 2 days, but mechanical strength reached after 28 days

Commissioning

The surface must not be exposed to the full range of stresses until the treatment system has fully dried, i.e. 7 days at 20°C and 60% relative humidity.

Between 2 days and 7 days, light traffic can be allowed, with the following precautions: microbreathable protective tarpaulins such as Landolt’s Floorliner Vapor, traffic in socks or overshoes. No exposure to water or chemical agents, no rubbing or scratching of furniture. It is forbidden to apply adhesives to coverings.

Do not lay carpet for 7 days.

VERY IMPORTANT NOTE:

• The maximum hardness of the Marius Aurenti Micro Concrete System is achieved after 28 days of drying.
• The floor must be handed over immediately after completion of the work. The freshly applied Marius Aurenti System must be protected from the work of other trades by protective materials that allow aeration (see Varnish n°7 Visco and Fixative IF3 Technical Data Sheet).
• Delay before first wet maintenance: 3 days minimum after application of Varnishes n°7 or IF3 Fixative.
• Follow the instructions in the Marius Aurenti maintenance booklet

Implementation

Precautions, prohibitions and warranty

To guarantee shade homogeneity, use the same Mineral Color Blush Concentrate batch number for the same job.

Never split a Mineral Color Blush Concentrate.

Never add water.

Each Blush Mineral Color Concentrate is colorimetrically tested. That said, due to the mineral and hydraulic composition of the materials, color variation is possible from batch to batch.

In fact, to produce a reference color (sample), it must be made using the same materials, the same batches of materials, on identical substrates, under the same weather conditions, with the same tools and with the same gestures.

Consequently, we cannot be held liable for any discrepancies.

For this reason, we always recommend carrying out a trial run before starting work.

Preparing Classic, Fluid, Ultra Fine, Terrace Micro Concrete

Dry mixing (for multiple use of the kit) or wet mixing (for complete use of the kit).

Dry mixing – Recommended for small application areas

Always mix component A and the concentrate in their entirety before dividing.

• Roll the bucket of Component A to aerate and soften the material
• Open the Component A bucket and make a slight indentation in the center of the base.
• Shake and open the jar of Blush Mineral Color Concentrate.
• Pour the Concentrate into the center of the base bucket
• Block the bucket with your feet, and mix, at low speed (a mixer for pasty products is recommended, please consult us for prices), so be gentle.
• Immerse the mixer and gradually increase the speed.
• Continue mixing with straight and angled vertical and lateral movements to perfectly blend the contents. Insist on the edges at the bottom of the jar, so as not to forget those corners that are most difficult to mix. When mixing for the first time, we recommend pouring the mixed contents into a bucket of the same size, to visually check the quality of the mix and repeat if necessary. Mixing time should not be less than 1 minute. The color in the bucket should be even at the end of mixing.
• Homogenize component B well, then introduce the mixture (component A + concentrate).
• Mix with a mechanical mixer until homogeneous and lump-free.
• Transfer the coloured powder into a perfectly clean, dry bucket.
• Stir the powder until a homogeneous color is obtained.
• Add component B (liquid) to the quantity of powder prepared.

Wet mixing – Recommended for large areas of application

• Pour Component B (liquid) into a clean, dry bucket.
• Shake and open the jar of colored concentrate.
• Add the jar of Color Concentrate, block the bucket and mix mechanically at low speed until a homogeneous mixture is obtained, in the proportions shown in the following table:

• Add the powder (component A) to the liquid.
• Mix mechanically for 2-3 minutes until homogeneous. Never add water.

Failure to do so may result in a change in shade.
