Flexible clay cladding, answered

What the material is, how it performs, how it goes on a wall, and what it costs. If your question is not here, ask us directly.

The material

What is MCM?

MCM stands for Modified Clay Material. It is a cladding made from coloured inorganic mineral powder — clay-based — blended with a high-performance water-based polymer modifier, then cross-linked and shaped by microwave irradiation. The result is a thin, lightweight sheet that carries the texture and colour of fired clay or natural stone but bends cold around a curve.

How thick and how heavy is flexible clay cladding?

Finished thickness is 2.5–3.5mm depending on the collection, and weight is approximately 4.5 kg per square metre. For comparison, a 25mm natural stone slab weighs roughly 55–65 kg per square metre, so the same elevation carries under a tenth of the dead load.

How is it different from a clay veneer or a stone veneer?

A traditional clay or stone veneer is a thin slice of rigid material — typically 5–20mm — that still has to be cut to shape, mitred at corners and mechanically supported on tall walls. Flexible clay is a bonded sheet at 3mm that bends around a corner instead of being cut to fit it, weighs a fraction as much, and needs no support frame.

What is the difference between Regular and Random pattern?

Regular pattern repeats a uniform face across every sheet, so veining and coursing align tile to tile — useful for book-matched effects and for tight, controlled walls. Random pattern varies the face sheet to sheet so no repeat is visible, which is what makes a large wall read as genuinely quarried. Above roughly six square metres, Random is usually the better call.

What sheet sizes are available?

Three standard formats: 595 × 1195 mm, 595 × 2395 mm and 1195 × 2395 mm. The 2395mm lengths run floor to ceiling in a single piece on most Indian residential heights, which removes the horizontal joint entirely. Because the material cuts with a knife on site, sheet size mostly affects joint layout rather than what is buildable — send us the wall dimensions and we will advise the most efficient set-out.

Performance

Is it fire rated?

Yes — Level A1, the highest non-combustible classification. That is what makes it usable on high-rise elevations, escape routes and protected stair cores where combustible cladding is not permitted.

Can it be used outdoors in the Indian climate?

Yes. It is waterproof, UV stable so a south or west elevation holds its colour, and fungus and algae resistant, which matters on a north wall through the monsoon. It is also freeze-thaw resistant, so it is suitable for hill-station projects.

Does it fade in direct sun?

No. Colour comes from inorganic mineral pigment distributed through the body rather than from a printed or coated surface, so a west-facing elevation holds its shade rather than bleaching out over a few summers.

Is it suitable for bathrooms and wet areas?

Yes. It is waterproof and fungus and algae resistant, so it carries straight through from a bedroom into an ensuite without a change of material at the door. This continuity is one of the most common reasons it gets specified on hotel and spa projects.

How long does it last, and what maintenance does it need?

Maintenance is washing down with water. There is no sealing cycle, no annual oiling and no re-grouting, because the colour is mineral pigment through the body rather than a surface coating, and there are no grout lines to discolour.

Can the colour be changed later?

Yes. The surface accepts mineral paint, so a wall can be recoloured without stripping the cladding off — useful for retail rollouts and hospitality refurbishments where the texture is worth keeping but the palette changes.

Specifying and installing

How tight a curve will it bend around?

The limit is quoted as a diameter: the tightest circle the sheet forms cold is 381mm — 15 inches — across, which is a 190mm radius. In practice that means it wraps any circular column of 381mm diameter or more, plus arches, barrel vaults, coves and curved reception fronts, with no heat, scoring or relief cuts. Vertically corrugated collections such as Ripple Stone and Liner Stone handle the tightest end best, because the corrugation absorbs the compression on the inner face. Below 381mm diameter, and on a sharp external arris, the bend is outside what the material will do — those need a radiused substrate or a conventional mitre.

What substrates can it be applied to?

Any sound, dry, level substrate: cement plaster, concrete, gypsum board, plywood, AAC block, brickwork and existing tile. The substrate needs to be free of loose material and dust, and level enough that undulation will not show through — deep-relief collections are less forgiving here than flat ones.

How is it fixed?

With a notched trowel and a polymer-modified adhesive applied to the substrate. The sheet is pressed on, worked out from the centre to expel air, and rolled. There is no mechanical fixing, no support frame and no wet cutting — sheets are trimmed with a knife or shears.

Do you install, or supply only?

We supply across India and can put you in touch with trained applicators in and around Bengaluru. The application itself is straightforward enough that most competent tiling or painting contractors pick it up quickly — our installation guide covers substrate preparation, adhesive, application and curing.

Buying from us

What does flexible clay cladding cost in India?

As an indicative supply rate, ₹350–₹450 per sq ft, supply only, ex-Bengaluru. Where a project lands in that band depends on the collection, the pattern variant and the quantity. The figure worth comparing is the installed cost, not the material rate: there is no support frame, no structural allowance, no wet cutting and far less labour, which typically brings the total below a natural stone equivalent even where the material rate is similar. Send us your area and collection and we will come back with a written quote.

Do you supply samples?

Yes. Tell us the collections you are considering and we will send physical samples — worth doing before committing, because relief textures and dual-tone veining behave differently under a project's actual lighting than they do in a photograph.

Where are you based and where do you deliver?

We have two branches in Bengaluru — Jayanagar 9th Block and Begur — and supply across Karnataka, Tamil Nadu, Telangana, Kerala and Andhra Pradesh, with despatch to the rest of India on request.

More questions

Is the material translucent, and can it be backlit?

Yes. Light passes through the body, so a panel lit from behind glows rather than staying flat — the effect people associate with backlit onyx, at a fraction of the weight and cost. Mount an even LED panel or a diffused strip array behind it rather than point sources, which show as hot spots through a 3mm sheet. Pale shades transmit most; dark ones read as a subtle halo at the joints. It works on façades, bar and reception fronts, and printed feature panels.
