.

Packaging:

The 2” (50 mm) wide plate is furnished in 250 ft (75 m) spools.

The 4” (100 mm) wide plates are furnished in 300 ft (90m) spools.

Surface Preparation:

• Surfaces to receive CFRP Plate laminates must be clean and sound. It must be dry and free of frost. All dust, laitance, grease, curing compounds, waxes, deteriorated materials, and other bond inhibiting materials must be removed from the surface prior to application.

• Large voids should be patched using an approved repair mortar. Uneven areas should be leveled with an appropriate leveling mortar or putty.

• Repair all cracks per project specifications.

• Sandblast, pressure wash, shotblast or use other approved mechanical means to achieve an open-pore texture with a concrete surface profile of CSP 3 or better (ICRI).

• The adhesive strength to the concrete may be verified after surface preparation by random pull-off testing

(ACI 503R) at the discretion of the engineer. Minimum

tensile strength of 200 psi must be achieved

• Scuff sand one side of the FRP laminate plate and

clean with acetone or other solvent to remove carbon dust.

Epoxy Mixing:

XQ-JGN31P epoxy is recommended for priming of substrate surface. Epoxy adhesives must be mixed according to the manufacturer’s specifications to achieve a homogeneous mixture.
