ICFs Wall Fiberglass Mesh Corners

Applications

ICF (Insulated Concrete Form) walls (internal and external external corners)

External Insulation Finished System (EIFS) plaster/stucco systems

Finishing of external corners such as door and window openings, parapet walls, eaves, and column corners

Advantages

Crack Prevention: The mesh fabric distributes stress in the plaster layer, eliminating corner cracking

Straightening: PVC strips ensure straight and aesthetically pleasing outside corners

Alkali Resistance: The fiberglass coating resists cement alkali, ensuring a long service life

Efficiency: No steel corner guards required; installation is 2–5 times faster

Installation Guidelines

Clean the wall corners to ensure they are flat and dust-free

Align the corner guard strip with the external corner, ensuring the mesh flaps are flush against the wall

Temporarily secure with insulation nails or mortar

Apply the first coat of plaster, fully embedding the mesh

Apply subsequent coats of plaster, ensuring the corner guard strip sits slightly below the finished surface
