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.

Standard Finishes
A starting palette of 6 colours.
All finishes are factory-tinted on order with lightfast natural mineral pigments. Custom colour matching available for project quantities ≥ 200 kg.

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
Industries Where Specified
Where Tadelakt works.
Hospitality
Boutique hotels, design-led cafés and contemporary restaurants are replacing flat paint with mineral-based art coatings. CALMURA supplies the full toolkit — limewash for guest rooms, marmorino for lobbies, microcement for bathrooms.
Luxury Residential
Polished marmorino, sculptural tadelakt, seamless microcement floors. CALMURA supplies the artisanal art coatings that high-end residential designers actually specify — with the documentation a project archive demands.
Wellness & Spa
Spas and wellness facilities demand wall and floor finishes that handle steam, water and humidity while creating the calm, mineral atmosphere guests come for. Tadelakt and microcement are the gold standards.
