For premium lime plaster, tadelakt, or microcement applications, substrate quality directly determines final outcome.

Drywall & Substrate Requirements:

• Level 4 minimum; Level 5 strongly recommended
• Properly sanded and dust-free
• No telegraphing seams, fasteners, or joint compound ridges
• Cement board or HardieBacker in wet areas
• Blueboard only when specified for system compatibility

Framing & Structural Considerations:

• Minimize deflection in walls and ceilings
• Stable framing at transitions and openings
• Proper backing at handrails and mounted fixtures

Moisture Control:

• Controlled interior humidity before installation
• No active leaks or curing concrete off-gassing
• Waterproof membrane system required in showers

Plaster is a final finishing trade and must be protected accordingly.

Ideal Sequencing:

• Drywall complete and paint-ready
• Millwork installed (when possible) before plaster
• Waterproofing complete in wet areas
• Major dust-producing trades complete

Environmental Requirements:

• Clean, dust-free environment
• Water and electricity active
• Stable temperature and humidity
• No exterior exposure without proper protection

Protection After Install:

• Cover adjacent surfaces immediately
• Prevent impact from other trades
• Avoid wet construction nearby during cure

Installing plaster too early or in uncontrolled environments is the most common cause of performance issues.

Builders who respect sequencing protect both budget and reputation.

Premium plaster is durable when installed and maintained properly.

Durability Factors:

• Lime-based plaster remains breathable and hardens over time
• Microcement performs well in higher-traffic applications
• Shower systems require sealing maintenance

Maintenance:

• Avoid harsh chemicals
• Clean with soft cloth and warm water
• Shower resealing typically required every 6–12 months when used daily

Repair Protocol:

• Small impact damage can often be blended
• Larger repairs may require refinishing a defined area
  
• 
  Waxed or polished finishes are more sensitive to patch blending
  

The key for builders: plaster is serviceable — but it must be treated as a mineral architectural surface, not painted drywall.

Architectural plaster is hand-troweled. It is not uniform like paint.

Builders should expect:

• Subtle tonal variation
• Layered compression marks
• Natural mineral movement

Consistency is maintained through:

• Dedicated crews per project phase
• Approved benchmark mockups
• Controlled batching and pigment mixing
• Sequencing by elevation or room to avoid break lines

Corners, returns, and transitions are intentionally blended, not masked.

Managing expectations early protects both schedule and client satisfaction.

Lighting is one of the most overlooked technical factors in plaster execution.

Plaster is a mineral surface with depth and movement. Under:

• Raking light
• Linear LED grazers
• Floor-to-ceiling window exposure
• Indirect cove lighting

…surface movement becomes amplified.

We recommend:

• Reviewing lighting plans before installation
• Performing mockups under final lighting conditions
• Adjusting texture intensity based on exposure

Plaster is not a sprayed paint product. Surface character will be visible — the objective is controlled movement, not unintended shadowing.

Builders who coordinate lighting and finish together avoid costly callbacks.

Absolutely. This is a standard practice for Marrwall's project management team.
