Store dry at 5 °C to 32 °C (41 °F to 89 °F). Condition product to 15 °C to 24 °C (59 °F to 75 °F) before using.

*Product cured and tested at temperatures indicated.

Hardened concrete to hardened concrete

Hardened concrete to steel

Fibre stress loading = 1.8 MPa (264 psi)

A:B = 3:1 by weight and by volume

Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point.

Approx. 1 h 50 min

The epoxy will reach its design strength after 7 days at 23 °C (73 °F).

Consumption is based on a 3 mm (1/8 in) nominal thickness and does not take into consideration the plane, roughness of substrate as well as laminate crossings. Actual consumption of adhesive will then be higher.

• Minimum age of concrete must be between 21 and 28 days, depending upon curing and drying conditions.
• Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. 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 silica sand).
• The concrete adhesive strength must be verified after surface preparation by random pull-off testing (ACI 503R) at the engineer’s discretion. 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 equivalent to CSP 3 minimum, as per ICRI-310.2R.
• Steel: Sandblast to white metal finish (SSPC SP5).
• Sika® CarboDur®: Surface should be wiped clean using an appropriate cleaner. Using a clean white cloth wipe down the side receiving adhesive (this side is not labeled) with acetone until all residual carbon dust is removed (i.e. the white cloth remains white after wiping the laminate).
  In the 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 cleaned as above prior to the application of the second strip.
• Timber: Blast clean or grind. After cleaning, remove all dust from the surface with an industrial vacuum cleaner.

• Pre-mix each component.
• Proportion 1 part of component B to 3 parts of component A by volume into a clean pail.
• Mix for three (3) minutes using a low-speed drill (300 - 450 rpm) to minimize air entrapment. Use a Exomixer® type mixing paddle (recommended model).
• During the mixing operation, scrape down the sides and bottom of the pail with a flat or straight edge trowel at least once to ensure thorough mixing. Upon completion of mixing, Sikadur®-30 should be uniform in colour.
• Mix only that quantity you can use within its pot life.

Clean all tools and equipment immediately with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically. Wash soiled hands and skin thoroughly in hot, soapy water.
