FAQ
Do you have a question? We'll answer it here
What exactly is "Béton Soyeux"?
Silky Concrete is a decorative, millimeter-thick concrete applied manually in thin layers. It offers a continuous surface, with no visible joints, and a soft, slightly powdery feel. Each creation is unique, as the applicator's handiwork and the light create singular nuances.
What surfaces can Silky Concrete be applied to?
Satin Concrete can be applied to many stable and sound substrates:
- Existing tiles
- Cement screed
- Raw concrete
- Plasterboard type BA13
- Well-prepared cement or plaster renders
In some cases, specific preparation or a levelling compound is necessary to guarantee adhesion and durability.
Can Silky Concrete be laid over existing tiles?
Yes, it’s one of its most common applications. The tiles must be perfectly adhered, degreased, and prepared (sanding, joint filling, suitable primer). We always analyze the condition of the substrate before validating this type of installation.
Is Silky Concrete compatible with underfloor heating?
Yes, Silky Concrete is compatible with most hydraulic or electric underfloor heating systems, provided that the installation rules (heating, temperature rise curves, expansion) are followed. We advise you to send us the technical information of your installation when requesting a quote.
Can Silky Concrete be used in a walk-in shower?
Yes, provided that the implementation is perfectly controlled:
- Suitable substrate and validated waterproofing upstream
- Slopes compliant towards drainage
- Treatment of angles and singular points
- Final protection by varnish or specific resin
We strongly recommend installation by an experienced applicator for areas directly exposed to water.
Is Silky Concrete suitable for wet rooms (bathroom, toilet, kitchen)?
Yes, it is ideal for bathrooms, toilets, and kitchens, on floors and walls, vanity tops, backsplashes, bathtub surrounds, etc. A water-repellent and oil-repellent protection is applied to limit stain absorption and facilitate maintenance.
What is the thickness of polished concrete?
The final thickness is generally between 2 and 3 mm (excluding substrate preparation). This allows for renovation without significant extra thickness or major leveling work.
Does silky concrete crack?
Silky Concrete follows the movements of the substrate. If the substrate is stable, prepared, and properly isolated from any structural cracks, the risk is controlled. However, an unstable, cracked, or poorly prepared substrate can lead to the appearance of micro-cracks. This is why we pay particular attention to diagnosis and preparation.
How resistant is Silky Concrete to stains and scratches?
Once protected (with a water repellent, varnish, or wax depending on the area), Béton Soyeux is highly resistant to everyday domestic use.
- For floors: regular maintenance and the use of felt pads under furniture will limit micro-scratches.
- For worktops: avoid localized impacts, direct knife cuts, hot dishes placed without protection, and very aggressive products.
Is Silky Concrete suitable for heavy use (boutique, restaurant, public place)?
Yes, provided that the right protection system is chosen and regular maintenance is planned. For high-traffic areas, we recommend a specific study, or even reinforced or hybrid systems depending on the project.
Do you offer implementation or only the materials?
We can supply materials only to trained professionals, or offer comprehensive support with our partner applicators. For a turnkey project, please indicate the type of location, surface area, and your location in the quote request form.
