Adhesives and Attachments

Strong adhesion comes from using basecoat correctly and getting full contact behind the moulding.

Required: Installation must conform to EIFS manufacturer requirements and your project specs. Basecoat selection and application method should match the specified system.

---

Use EPS-safe, system-approved materials

• Use EIFS-compatible basecoat per your project specification.
• Avoid solvent-based adhesives or cleaners that can damage EPS foam.
• Follow manufacturer mix ratios, pot life, open time, and cure time.

Typical basecoat application approach (general)

Application methods vary by system, but commonly include:

• A continuous basecoat pattern that supports the profile
• Or a full-bed application using a trowel for maximum contact

Key goals:

• Maximize contact between moulding and substrate
• Avoid large voids behind the profile
• Keep edges aligned with your layout lines

---

Install and brace

• Press moulding into place and “seat” it to ensure good contact.
• Check level/plumb and alignment to your layout lines.
• Use temporary support (tape, clamps, braces) as needed while curing.

---

Mechanical fastening (when required)

Some conditions may require mechanical support (especially large profiles, difficult substrates, or per engineering/specs). If mechanical fasteners are used:

• Follow project requirements for fastener type and placement
• Avoid crushing/denting the profile
• Patch fastener points per the finish system

---

Curing conditions (don’t rush)

Keep the installation within approved conditions:

• Do not use frozen material
• Do not apply to frozen substrate
• Temperature should not be less than 5°C (41°F) before, during, and until coatings cure

If your system specifies a higher minimum, follow that.
