Description

Sikadur-30 is a 2-component, 100% solids, moisturetolerant, high-modulus, high-strength, structural epoxy paste adhesive. It conforms to the current ASTM C-881 Type I, IV Grade 3, Class C and AASHTO M-235 specifications. Questions? Contact Us.

  • Sikadur-30 may only be used by experienced professionals. Adhesive for bonding external reinforcement to
    concrete, masonry, steel, wood, stone, etc.
  • Structural bonding of composite laminates (Sika CarboDur CFRP) to concrete.
  • Structural bonding of steel plates to concrete. Suitable for use in vertical and overhead configurations.
  • As a binder for epoxy mortar repairs.

The concrete surface should be prepared to a minimum concrete surface profile (CSP) 3 defined by the ICRI
surface-profile chips. Localized out-of-plane variations, including form lines, should not exceed 1/32 in. (1 mm).
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 (e.g., Sikadur 30 with the addition of 1 part oven-dried sand). The adhesive strength of the concrete must be verified after surface preparation by random pull-off testing (as defined by ACI 503R, ASTM C1583) at the discretion of the
engineer. Minimum tensile strength, 200 psi (1.4 MPa) with concrete substrate failure.

For bonded, external reinforcement: Apply the neat mixed Sikadur 30 onto the concrete with a trowel or spatula to a nominal thickness of 1/16” (1.5 mm). Apply the mixed Sikadur 30 onto the CarboDur laminate with a “roof-shaped” spatula to a nominal thickness of 1/16” (1.5 mm). Within the open time of the epoxy, depending on the temperature, place the CarboDur laminate onto the concrete surface. Using a hard rubber roller, press the laminate into the epoxy resin until the adhesive is forced out on both sides. Remove excess adhesive. Glue line should not exceed 1/8 inch (3 mm). The external reinforcement must not be disturbed for a minimum of 24 hours. The epoxy will reach its design
strength after 7 days.
