Marrwall plaster is specified as a primary architectural material, not a finish layer.

Our lime-based and mineral plasters provide:

• Physical depth (multi-layer application)
• Mineral mass and breathability
• Subtle surface compression from hand troweling
• Light absorption and diffusion properties

Unlike paint or wall-covering, plaster becomes part of the wall assembly. It reads as:

• Monolithic when applied with restrained movement
• Layered and tactile when intentionally articulated
• Sculptural when designed to interact with light and geometry

In high-end architecture, plaster is used to eliminate visual interruption — creating continuous, mineral surfaces that contribute to spatial clarity and material honesty.

All Marrwall plaster is hand-applied. Variation is inherent — control is intentional.

Expected characteristics:

• Subtle tonal shifts
• Layered compression marks
• Mineral aggregate depth

Control is achieved through:

• Project-specific mockups approved under final lighting
• Dedicated crews assigned per project phase
• Continuous application across planes to avoid cold joints
• Controlled pigment batching and mixing

Large uninterrupted walls require sequencing strategy. Movement can be calibrated to either enhance monumentality or soften scale.

The difference between artisanal and inconsistent lies in crew discipline and process control. We train our team regularly across brands, materials and applications to ensure we produce the highest quality work.

Plaster edits light.

Because it is mineral-based and matte to semi-polished depending on specification, it:

• Diffuses direct light
• Softens shadow transitions
• Enhances depth under grazing illumination
• Reveals geometry at edges and reveals

Under raking or grazing light, movement becomes more pronounced. Under indirect lighting, plaster reads quieter and more monolithic.

Architecturally, plaster can:

• Amplify ceiling height through vertical movement
• Compress scale when applied with restrained texture
• Define shadow lines at reveals and terminations

Lighting strategy and plaster specification should be coordinated early in the design process.

Plaster rewards precision.

Design considerations include:

• Level 4 minimum substrate; Level 5 preferred for high exposure areas
• Tight control of flatness tolerances
• Stable framing to prevent deflection cracking
• Clean, continuous edges at reveals and transitions
• Proper corner treatment to prevent future cracking

Minimum radii for curved applications depend on system and substrate stability.

Integration with:

• Stone, Metal, Millwork, Glazing systems

…requires clean termination details and sequencing coordination.

Plaster will not conceal framing irregularities or poor drywall preparation. It demands substrate integrity.

Lime-based plaster continues to carbonate over time, increasing hardness and durability.

Long-term performance characteristics:

• Breathability reduces trapped moisture risk
• Mineral composition resists peeling or delamination
• Subtle patina develops with time and touch

In matte finishes, wear can enhance character. In highly polished or waxed systems, maintenance expectations increase.

Repairability:

• Minor impact damage can often be blended
• Larger interventions may require refinishing a defined plane
• Wet environments require periodic resealing depending on system

A well-specified plaster system matures — it does not degrade.

Absolutely. It is a project standard for a Marrwall project manager to approve a large sample onsite before proceeding with installation.
