Adhesives and Attachments
Updated April 01, 2026
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.
