Basic repairs must be made to the structure prior to strengthening with Fiberbond. Spalled concrete removed, corroded or damaged steel addressed and major cracks injected.

The surface to be repaired is typically abraded to smooth out irregularities, remove contaminants and radius sharp corners. This can be performed by shot or sand blasting, water jet or grinder.

In order to promote adhesion and prevent the surface from drawing resin from the FRP, a low viscosity epoxy primer is applied with a roller until the substrate is locally saturated.

An adhesive, high viscosity putty is applied when necessary to the surface to fill in ‘bug holes’ offsets or voids.

In a clean area away from the resins, the fabric is carefully measured and cut in accordance with the specifications.

On large, high volume projects, the fabric can be saturated using Edge Structural Composites’ custom saturator. For lower volumes & shorter strips, the fabric can be either saturated on a table, or the surface can be coated with resin and the dry fabric applied.

The pre-wetted, or dry, fabric is carefully laid onto the surface and smoothed out to remove air bubbles and ensure that the fibers are straight.

During the cure, 2 to 6 hrs depending on ambient conditions, the fabric is checked to ensure that all air bubbles are removed and that the fabric is not sagging. Edge Structural Composites highly recommends that a trained, qualified inspector monitor applications.

Good record keeping in accordance with Edge Structural Composites QA/QC procedures ensures a successful repair.

Once cured and inspected, Fiberbond can be coated with any coating, for aesthetic blending and low maintenance protection.
