The material

Texture and character, worked by hand.

Crustal is a mineral wall covering that adds texture and character to a wall. It offers a robust, natural look with real depth and variation; its coarser texture gives a raw, tactile quality that creates a timeless, authentic atmosphere. It is also an elegant way to finish rougher surfaces — its own structure counterbalances the roughness of the substrate.

Crustal is pigmented throughout. Working with combs, brushes or spatulas — and adding coloured pigments — the applicator can create countless textures and shades, from a uniform, chalky matt to a heavily textured wall. The final result depends entirely on the craftsman and their hand.

It is, first and foremost, a mineral system: a white powder, coloured on site by mixing with mineral pigments and water, that cures to a matt, chalky stucco or a raw, natural texture.

Textures

One material, many hands.

The same powder becomes a family of surfaces — smooth and chalky, finely mineral, coarsely textured, or combed like timber.

The system

How it goes on.

Composition
A versatile, mineral-based decorative wall plaster. Supplied as a white powder, coloured on site by mixing with powdered mineral pigments and water, then hand-applied and cured to a matt, chalky stucco or a raw, natural texture.
Equipment
Crustal powder (4 kg or 16 kg bags) and Stoopen & Meeûs powder pigments, with StucPrimer and a suitable topcoat (Uniwall 1KPU or CrustalFix). Tools: a mechanical mixer, clean water, a Venetian trowel and texturing tools such as a Crustal brush or roller.
Protection
Crustal can be protected against moisture and stains with a fine coat of Uniwall 1KPU. Where a CrustalAccent colour wash has been applied, it is first sealed with CrustalFix before any further protective coat. Representative tests are always carried out first.
Where it's used
For interior walls, ceilings and furniture, on stable, solid, dry and clean substrates. It suits virtually all common mineral building materials and boards, provided the surface is properly prepared. High-quality workmanship is essential to the result.
