Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials, and other bond inhibiting materials from the surface. Existing uneven surfaces must be filled with an appropriate repair mortar (i.e. Sikadur®-30 with the addition of 1 part sand). The adhesive strength of the concrete must be verified after surface preparation by random pull off testing (ACI 503R) at the discretion of the engineer. Minimum tensile strength: 1.5 MPa (218 psi) with concrete substrate failure.

 
Planeness of substrate to be checked with a metal batten. Tolerance for 2 m (6.5 ft) length max. 10 mm (3/8 in), or 2.5 mm (3/32 in) for 50 cm (20 in) length respectively.

 
Concrete: Blast clean, shotblast or use other approved mechanical means to provide an open roughened texture.
Steel: Sandblast to white metal finish.
Timber: Plane, sand or grind. Remove all dust from the surface with an industrial vacuum cleaner.
CarboDur®: Surface should be wiped clean using an appropriate cleaner. Using a clean white cloth, wipe down the side receiving the adhesive (this side is not labeled) with acetone until all residual carbon dust is removed (i.e. white cloth remains white after wiping the laminate). In case where the design requires “stacking” of the strips, the bottom surface of the strip (labeled) should be lightly sanded (emery paper type 180) and wiped clean, prior to the second strip application.
