Why specify Tadelakt

What this coating does that paint cannot.

Naturally waterproof

No synthetic sealers required — the saponification of lime with olive-oil soap creates a calcium-stearate barrier.

Joint-free & sculpt-able

Apply over curved walls, alcoves, vanities and bath surrounds without joints or visible breaks.

Living patina

Develops a softer, more luminous patina over years of use — gracefully ages rather than degrades.

Antimicrobial by default

High alkalinity inhibits microbial growth — ideal for humid wellness environments.

In Detail

About Tadelakt Natural

Tadelakt is an ancient Moroccan lime plaster traditionally used in hammams (steam baths), made waterproof through an arduous process of polishing with a serpentine stone and saponifying the surface with black olive-oil soap. CALMURA Tadelakt Natural is supplied as a high-purity slaked lime base with natural mineral pigments and the proprietary CMR-Hammam soap finish. The result is a continuous, joint-free, water-tight surface ideal for spa walls, residential bathrooms, sinks, soaking tubs and sculptural curved features.

Common Applications

  • Hammam, spa and steam-room walls and ceilings
  • Residential bathrooms (full wet zone)
  • Built-in sinks, soaking tubs and shower benches
  • Curved feature walls and arched alcoves
