Permissible substrates

The diversity of substrates and their conditions calls for specific preparation and primers.

Substrates must be sound, flat, dry, rigid and cohesive, stable and clean (especially free of grease, oil or laitance).

They must be carried out in accordance with current DTU standards. It is important that the substrate be cohesive and free of cracks.

Active cracks and expansion joints will be left open and will not be covered. They will be treated with MS Polymer Color Marius Aurenti joint filler after the Classic waxed concrete has been applied.

Concrete and screed substrates must be at least 28 days old. They must be flat, cohesive, clean and have a moisture content of <4% or 0.5% for calcium sulfate-based fluid screeds.

A) New paving slabs, concrete floors over crawl spaces and poured concrete floors over steel tanks

Concrete slabs and concrete floors over crawl spaces must be laid in compliance with standard NF P 11-213 (DTU 13.3); they must be reinforced in compliance with the same DTU.

B) Pool and pond supports

For swimming pools and ponds, please refer to the Marius Aurenti swimming pool guide for specific substrate preparation and application methods.



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. Mixing concentrates is strictly forbidden.

Béton Ciré Terrasse bases are semi-finished materials. It is essential to add a concentrate to them to ensure that the properties of Béton ciré Terrasse are integral and the formula stable. Even in white, the addition of a white Mineral Color Blush Concentrate 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.


Do not apply to solid wood, softwood floors, plastics and textiles, terracotta and terracotta tiles.

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 the 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, making straight and slanted vertical and lateral movements to blend the contents perfectly. Pay particular attention to the edges at the bottom of the jar, so as not to miss those corners which are most difficult to mix. When mixing for the first time, we advise you to pour the mixed contents into a bucket of the same size, so as to visually check the quality of the mix and repeat it if necessary. Mixing time should 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:

COMPONENT B (liquid)

in kg


+ BLUSH concentrate Mineral color (colored powder)

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 Concentré
  • Pour the Concentrate into the liquid
  • Block the bucket and mix at progressive speed until the liquid and concentrate are homogeneous.

Never add water



The Marius Aurenti Waxed Concrete System must be applied in a relative ambient humidity range 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 application, check substrate moisture content (maximum 4% and ≤0.5% for calcium sulfate-based fluid screeds).


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 Waxed Concrete System can be applied at ambient temperatures between 5°C and 25°C for Waxed Concrete and between 15°C and 25°C for 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 and accelerate setting. Do not apply in frosty or hot weather. Heating or cooling systems should be provided 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.

The slope

Obviously, since we're subject to severe climatic conditions, we recommend careful work on the subgrade, the mesh, the joints and the quality of the concrete, to avoid cracks in the substrate that can't be repaired.

A minimum slope of 2% towards the outside is recommended to drain off rainwater.

The use of additives such as plasticizers, fibers and curing agents is essential to ensure a high quality surface for waxed concrete.

A smoothed finish during casting will match the future millimetric waxed concrete on top.


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

It is important to mechanically sand the slab and check for flash.

Apply a first coat of Béton Ciré at a consumption of approx. 3 kg/m² (approx. 1.5 mm thick) using a float or 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 Béton Ciré. 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), the surface can be sanded to remove decorative effects or excessive irregularities (40 grit) using a single-brush machine (or orbital sander), followed by thorough mechanical dusting.

Apply the second coat at a rate of approx. 1 kg/m², using a stainless steel trowel or smoothing machine. This second coat determines the final grain of the coating and its aesthetic appearance. It is important to note that a stainless steel application tool can leave dark marks (especially on light colors). A plastic tool may be preferable.

The second coat is finished with a more or less rough finish to reinforce the anti-slip properties of this mortar, particularly on frequently damp surfaces. In fact, a rubbed or grained finish using a dry sponge is ideal for barefoot traffic areas to avoid the risk of slipping.

If anti-slip properties are not required, after 24 hours drying time (at 20°C), sand the surface (grit 80 then 120) using an orbital sander (or a single-brush sander for floors), then remove dust with 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 finish. 2 days (20°C, 60%HR) after mortar application, without prior sanding, apply 2 finishing coats of Marius Aurenti Impregnation Terrasse n°2. This finish gives a satin appearance and darkens shades slightly (wet look).

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 controlled. 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 responsible for any discrepancies.

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

How to lay waxed concrete outdoors

Installing waxed concrete outdoors requires 2 series of operations to be carried out correctly:

1/ laying a concrete slab according to the rules of the trade

2/ lay the smooth, fine mortar coating, then its finishing touches, known (improperly) as waxed concrete

I. Creating a high-quality concrete slab

I.1. Earthworks

Before you can lay a concrete slab, you first have to do some earthwork:

  • disburse
  • flatten
  • lay a hedgehog, i.e. a thick, compact, packed bed of pebbles, a draining, resistant layer on which to spread the concrete, as if the slab were floating on it; the type and thickness of the pebbles is very important!

The slope should be well-directed so that rainwater runs off towards the outside, never towards the building.

I.2. Preparations: capillary rise and frost protection wick

We'll also create a capillary break to prevent capillary rise (water rising spontaneously in a porous material if it's in direct contact with damp earth).

In regions subject to frost, we use a frost-free spade that plunges into the soil.

I.3 Dividing and expansion joints

A uniform concrete slab on a floor that, by its very nature, is not always or not all the time uniform, inevitably entails the risk of breaking, cracking or crazing.

To avoid these risks, expansion and separation joints must be installed.

A joint should measure a third of the slab's thickness. The aim is to create a point of weakness, so that in the event of ground movement, it will clearly break at that point.

This expansion joint is standardized in the DTU 13-3.

Joints must be installed wherever there are corners or objects: a socket, a post, etc. These joints serve to separate the slab from these objects, preventing them from applying mechanical stresses that could damage it.

There are joint backings available, based on polystyrene.

In contact with a garden or any earth surface, the edge of the concrete slab is likely to absorb water by capillary action, thus swelling and fracturing, even more so due to freeze/thaw cycles; the uneven presence of moisture would also lead to slight color changes. So we'll strip the surface, treat the exterior with waterproofing finishes and, here too, install expansion joints.

I.4. Laying the concrete slab

To make a quality concrete slab, it's best to order your concrete from a concrete batching plant; while it will cost a little more, it will already be homogeneously mixed and pumped into place.

Advantages: saves time, improves mechanical stress, homogeneity, density and fluidity of concrete.

Working alone with a concrete mixer, by hand, exposes you to errors in dosage and temperature, which will result in a poorer-quality slab when it dries. But to lay millimetric waxed concrete, the quality of the slab is essential.

What's more, the concrete ordered from the plant is admixed with fibers to minimize shrinkage during drying, as if a large spider's web ensured the solidity of the whole and its resistance to mechanical stress.

In additives, superplasticizers such as sicalatex give it greater expansion capacities and enable it to cope better with drying.

It's advisable to spray a curing compound over the slab, which will protect it during the drying process, whatever the weather conditions and their changes, just as a film would over food.

The curing compound is then cleaned by light sanding, before the waxed concrete coating is applied.

II. Laying the smooth fine mortar coating ("waxed concrete")

II.1 A 2mm thick coating

Marius Aurenti will lay a 2mm coating on the concrete slab.

When it comes to quantities to be used, there's no question of skimping: the minimum thickness of waxed concrete plaster is really at least 2mm; outdoors, it's out of the question to use less, or you'll end up with a less durable result. You want to build a terrace that will last for decades, not cut corners that will cost you a new job in 5 years' time!

For 100m², for example, we'll use 4 kilos of "waxed concrete" coating per square metre, i.e. 400 kilos.

Once again, the quality of the underlying concrete slab is paramount: there's no question of trying to "recover" it by using plaster.

Coats of plaster are applied overnight, for a fresh-on-fresh effect that improves adhesion.

II.2. Surface treatment

The concrete surface will be treated in accordance with its intended use.

In fact, for every use of a surface there are standards for slipperiness; for pool edges there are standards such as PC-20 and PN 24. Otherwise, you run the risk of slipping and injuring yourself...

This surface treatment involves graining the concrete to make it both smooth and rough.

Different treatments can be applied to the same surface, to obtain surface textures adapted to specific uses:

  • a kitchen area that's easier to clean
  • a non-slip pool deck
  • and the rest of the terrace in "normal" cladding

II.3 Choice of colors

To choose the right color for your waxed concrete, you need to take into account the concept of luminous luminance or visual luminance.

Luminous luminance is the ability of a color to reflect light, linked to its capacity to store heat.

It needs to be adapted to the climate and the orientation of the surface (south-facing, north-facing in the shade...), so that the colors are vibrant without overheating in summer.
