Environment Conditions and Storage

Correct environmental conditions are one of the biggest factors in a clean install and durable finish, especially for exterior work.

Required: Execution of installation must conform to EIFS manufacturer requirements and project specifications.

Temperature and freezing restrictions (critical)

• Frozen material should not be used.
• Application to a frozen substrate is prohibited.
• Temperature before, during, and until coatings cure should not be less than 5°C (41°F).

If your adhesive/basecoat/finish system specifies a higher minimum temperature (common), follow the most strict requirement.

Weather and jobsite readiness

For best results:

• Avoid installing during rain, snow, or heavy fog, especially before coatings have cured.
• Protect freshly installed mouldings from wind-driven rain and direct water exposure until fully cured.
• Avoid extreme heat, direct sun, or high winds that can cause coatings to dry too quickly and reduce bond quality.

Substrate conditions

The bonding surface must be:

• Sound (not crumbling or delaminating)
• Clean (free of dust, grease, loose paint, or release agents)
• Dry (no ice, frost, standing water, or saturation)

Moisture trapped behind trim is a common cause of failures. For exterior projects, follow EIFS detailing to keep water managed and moving away from the assembly.

Storage and handling (to prevent warping and damage)

• Store mouldings flat, supported, and off the ground.
• Keep products covered and protected from weather and jobsite debris.
• Avoid leaving material in direct sunlight or high heat for long periods.
• Handle carefully to protect edges and finished surfaces.

Cure time reminders

Adhesives and coatings need stable conditions to cure properly. Cure times vary by product, temperature, and humidity, so always refer to:

• EIFS manufacturer instructions
• Product technical data sheets (TDS)
• Project specs
