Adhesive

It is imperative that a suitable EIFS adhesive is applied to the back of the insulation board to ensure that it adheres to the substrate.

Terraco offers two options in this regard:

  • Terraco Styrofix - a polymer modified dry-mix adhesive applied between the substrate and the insulation board to secure the board to the wall in the Terraco EIFS System;
  • Terraco Styrofix PU Foam Adhesive - a one-component, low pressure polyurethane adhesive foam for fixing certain types of insulation boards to the substrate.

Styrofix PU Foam Adhesive
A one-component, low pressure polyurethane adhesive foam for fixing EPS / G-EPS / XPS insulation board to a substrate. It is also used for filling gaps between EPS / G-EPS / XPS insulation boards, between the window / door frame and the insulation board, and for fixing external window sills. It has excellent thermal insulation and adhesive properties, is easy to use, economical, odourless, light weight and quick setting.

 APPLICATION METHOD

The application method depends on the substrate onto which the insulation panel is being fixed.

Spot Method

Apply Styrofix adhesive to 6 inner spots on the back side of the insulation board, ensuring it covers 40% of the surface area.
(Coverage: 4 - 5 kg/m²)

Ribbon & Dab Method

Apply Styrofix adhesive to the external edges and to 8 inner spots on the back side of the insulation board, ensuring it covers 40% of the surface.
(Coverage: 5 - 6 kg/m²)

Notched Trowel Method

Apply Styrofix adhesive to the entire back surface of the insulation board using a notched trowel.
(Coverage: 4 - 5 kg/m²)
