Why wall finishes are a specification decision
In contemporary architecture and interior design, wall finishes are no longer a final “color
choice.” They affect how a space performs, how it ages, and how it is maintained. In
hospitality, retail, multi-family, and high-end residential projects, finishes must withstand regular
contact, cleaning cycles, and changing environmental conditions—while still delivering the
desired aesthetic.
This is why wall finishes should be treated as a specification decision, not a last-minute
decorative layer.
The core performance criteria architects should evaluate
When selecting and specifying a wall finish system, consider the following categories:
1) Durability in use
• Expected traffic level (corridors vs. feature walls)
• Impact/abrasion risk (lobbies, public areas, commercial circulation zones)
• Expected service life before refresh
2) Cleanability & maintenance
• How often will it be cleaned?
• What cleaning products will be used?
• Does the surface show marks easily (scuffs, handprints)?
3) Moisture & environmental exposure
• Is the area exposed to humidity (bathrooms, spas, kitchens)?
• Are there temperature swings (entry areas, poorly insulated walls)?
• Ventilation quality and condensation risk
4) Substrate compatibility
• Existing substrate (drywall, plaster, cementitious board, previously painted
surfaces)
• Surface flatness and integrity
• Cracks, joints, or movement that may telegraph through the finish
5) Visual outcome + lighting behavior
• Matte vs. soft sheen vs. reflective effects
• How the finish reacts under daylight vs. artificial lighting
• Desired level of variation (uniform vs. artisanal movement)
Paint vs. decorative coating systems: system thinking
Traditional paint typically functions as a relatively thin finishing layer. Decorative coatings, by
contrast, are usually approached as systems—with preparation, priming, and finishing stages
designed to achieve a specific look and performance profile.
A system approach helps teams control:
• Texture and depth (visual richness)
• Consistency across larger wall areas
• Long-term behavior (how the surface ages and is maintained)
Where decorative surfaces add value in modern projects
Decorative coating systems are most beneficial when the project requires:
• A material-forward interior language (stone-like, mineral, plaster aesthetic)
• A finish that becomes part of the design identity (feature walls, reception)
• The ability to create seamless contemporary surfaces
• A finish that communicates premium quality without heavy ornamentation
Specification workflow: what to request before final selection
To de-risk the selection and avoid surprises during installation, architects and designers should
request:
• Sample boards in the intended texture/effect
• A recommended system build-up (prep + primer + finish approach)
• Application guidance (what conditions, tools, and skill level are required)
• Lighting notes (how to review samples under project-like conditions)
• Guidance on maintenance and cleaning for the specific finish
