Marrakech agency · Wall and floor finishes
Polished concrete (béton ciré) is a continuous mineral finish, trowelled in thin coats onto floors, walls, worktops or showers and then sealed with a varnish or wax. Our teams apply it in Marrakech apartments and villas, with careful preparation of the substrate, which decides everything else. You can follow the works from abroad, with photos every week.

Polished concrete is a fine mortar made from cement and resins, applied with a trowel in thin coats. Once dry it is sanded and then protected with a sealer or wax, which improves its resistance to stains and water. It gives a continuous, jointless surface with a mineral look and a slightly clouded tone: the cloud effect varies from wall to wall depending on the plasterer’s hand.
Its strength lies in its thinness and its versatility. It can be laid over old tiles that have been properly prepared, over a screed, a plastered wall or a board worktop. In Marrakech it appeals to villa and apartment owners who want a contemporary floor without the cutting and joints of large-format tiles, or a kitchen worktop in a single piece.
If you are planning a villa renovation in Marrakech, polished concrete should be thought through from the plans onwards: continuity of floors between rooms, thresholds, floor drains, upstands and door finishes.
Each surface has its own constraints. Polished concrete is worked differently depending on the use, the wear it will take and the presence of water.
In an apartment renovation in Marrakech, polished concrete can unify a living room, an open kitchen and a hallway without changing material.
Polished concrete almost always cracks, lifts or stains because of the substrate, rarely because of the product. Preparation therefore takes up a large share of the job, and it is what we go through in detail from the first visit.
| Substrate | What to check | Usual preparation |
|---|---|---|
| New screed or slab | Flatness, residual moisture, cracks | Levelling compound, bonding primer, treatment of expansion joints |
| Old tiles | Adhesion of the tiles, grout, flatness | Removal of hollow-sounding tiles, levelling, primer |
| Plastered or plasterboard wall | Cohesion, damp, cracks | Crack repair, skim coat, primer |
| Board for a worktop | Stability, expansion, moisture | Suitable board, reinforced tape at joints, primer |
| Shower | Waterproofing, falls, drainage | Waterproofing beneath the finish, upstands, specific primer |
A damp substrate is a case apart: the cause must be treated before any finish. Our guide to damp in riads sets out the mechanisms, which are just as useful for a villa or an apartment.
We measure the surfaces, check the substrates, mark expansion joints and discuss colours and the level of wear you expect. The visit can take place on site or by video call.
Levelling, repair of cracks, protection of joinery and skirting boards, and a bonding primer suited to the substrate.
Several thin passes are applied, with light sanding between them to refine the surface and even out the colour.
Varnish, resin or wax depending on the area and the wear. The choice affects the look (matt or satin) and the resistance to stains.
Inspection of the surface with you, end-of-works cleaning, and handover of the technical data sheets and care instructions.
Finishes are chosen just like the colour: matt for a natural-stone look, satin for a kitchen floor that is easier to clean. High-wear areas (entrance, kitchen) benefit from reinforced protection. Drying and the moment the surface can be used again depend on the substrate, the season and the system chosen: these points are set out in the quote.
Polished concrete is not always the right answer. Here is how we compare the options with clients, room by room, according to how each space is used.
| Criterion | Polished concrete | Tadelakt | Large-format tiles |
|---|---|---|---|
| Look | Continuous, mineral, contemporary | Clouded, silky, traditional | Crisp, regular, fine joints |
| Wet areas | Yes, with suitable waterproofing and protection | Yes, the reference material | Yes, substrate and joints need care |
| Heavily used floors | Possible with reinforced protection | Less common on floors | Very suitable, very hard-wearing |
| Repair | Local repair, the match needs care | Local repair with lime | Replace a single tile |
| Spirit | Modern villa, loft | Riad, hammam, bathroom | Any style, large areas |
If you are undecided, tiling and zellige in Marrakech are a solid alternative for busy floors and terraces. A project can also mix them: tiles on the entrance floor, polished concrete on the living-room walls, tadelakt in the shower. We think room by room.
Everyday care is simple: a soft broom or a damp mop with a pH-neutral cleaner. Avoid paint strippers, acidic or chlorine-based products, abrasive sponges and direct steam. Stains (oil, wine, citrus) should be wiped up quickly. Furniture legs should be fitted with felt pads.
Polished concrete goes on near the end of a project, once the electrics, plumbing, partitions and painting in Marrakech are complete, and before the furniture is installed. A single site manager plans that sequence, protects the surfaces and sends you photos every week on WhatsApp. You approve colours on a sample and receive a fixed, itemised quote within 48 hours of the visit.
The statutory guarantees that apply to the works and the manufacturers’ guarantees are set out in your quote and handed over at completion, together with the technical data sheets. To round off the project, see the page on decoration and finishes, the cost breakdown for a villa renovation or request your quote.

What you get on every project, before, during and after the works.
Answers to the questions we are asked most often.
The price is set after the visit: it varies with the surface area, the condition of the substrate, the type of protection and whether a shower or a worktop is involved. We never give a figure without seeing the place. After the visit, on site or by video call, you receive a fixed, itemised quote within 48 hours, with the options clearly laid out.
Often yes, provided the tiles are well bonded and the surface is flat enough. Hollow-sounding tiles are removed, the grout lines are filled and a bonding primer is applied. We check this during the visit and tell you whether removal is the better option. This step determines how well the finish holds up, so it is never done lightly.
Yes, provided there is waterproofing designed beneath the finish, correct falls and suitable protection. A shower demands more rigour than a dry wall. Tadelakt is also a very good option, and we compare the two with you according to the look you want. We show you finish samples so that you can judge the result in context.
It can, if the substrate moves or was badly prepared. Prevention means checking the substrate, treating cracks, respecting expansion joints and using reinforced tape at junctions. An isolated hairline crack can be repaired locally. During the visit we explain where a joint is preferable to a continuous surface.
A soft broom and a damp mop with a pH-neutral cleaner are enough. Avoid paint strippers, acidic or chlorine-based products and abrasive sponges. Put felt pads under furniture. We hand over care instructions at completion, with the data sheets for the sealer used. If in doubt about a product, ask us before you use it.
Some outdoor surfaces are possible with a system suited to sun, water and temperature swings, a terrace for example. It calls for a study of the substrate and of how rainwater drains away. After the visit we tell you whether polished concrete makes sense or whether another covering would serve you better.
Large-format tiles cope very well with heavily used floors and can be replaced one tile at a time. Polished concrete gives a continuous, jointless and more decorative floor, but needs careful protection. The choice depends on how the room is used, your budget and the look you want. We can also combine the two room by room, with no single option imposed.
Yes. A video-call visit, samples approved remotely, a single contact, weekly photos on WhatsApp and handover with you or your representative. The trades are coordinated so that the polished concrete goes on at the right moment, over a substrate that is ready. You keep control of every approval without needing to be there.
