Two component epoxy adhesive / repair compound
Two component, solvent free, fine aggregate filled, thixotropic, non-slump, polyamide cured epoxy.
Repairing and patching defects in concrete such as honeycomb and spalls. Fabricating components and repairing defects in fibre cement products.
In applications as a bedding mortar, gap filling and concrete repairs like spalling, crack filling and repairs to arrisses.
Including external carbon fibre structural reinforcement to be bonded to elements for structural strengthening,
see durafibre CFP data sheet.

- Excellent creep resistance
- Thixotropic, soft non-sag paste
- No primer required
- Excellent mechanical and chemical resistance
- Excellent water resistance
- Solvent free
- Impermeable to liquids
Any surface to be repaired with durafibre CFP must be clean, mechanically sound and dry. Concrete surfaces should be chipped to expose main aggregate and in the case of honeycomb, all suspect material must be cut out. See our concrete repair systems. The prepared surface must have an open textured finish and be free of all laitance, paint, prior surface treatments, loose or friable particles, debris and any contaminants that may impair the bonding properties of the adhesive prior to placing the durafibre CFP adhesive.
The surface must be level and surface irregularities must not exceed ≤ 1.0 mm in height. Level tolerance must not exceed 10 mm over a 2 m span.
The final prepared surface to receive the durafibre CFP adhesive and durafibre CFP plates must provide a minimum tensile adhesive strength of 1.5 MPa.
The concrete element should be at least 28 days old.
The existing ground face of the durafibre CFP plates are to be thoroughly wiped with MEK solvent and allowed to dry completely, approximately 10 minutes before applying the durafibre CFP adhesive.
All blemishes in the surface such as pop-outs, omegas, blowholes and honeycomb should be patched with epidermix® 314 or durafibre CFP adhesive, or as advised be a.b.e.®
Where the surface property values are suspect then view the durafibre CFW carbon fibre wrap system.
Set up equal volumes of base and activator side-by-side on a clean board. Do not take more than about 250 ml of each compound. Using a trowel or spatula mix thoroughly until a uniform colour is obtained. Mechanical mixing may be carried out using a drill at slow speed not greater than 500 rpm and a helical mixing paddle. Mix the two components together thoroughly, approximately 3 minutes, until a uniform colour is obtained.
Avoid high speed mixing as this will entrap air and impair the products performance.
Note: Ensure that all the mixing equipment and containers are clean prior to use.
Do not mix more than can be applied as per the product’s pot life.
Do not add solvents for thinning purposes, should the material stiffen up due time lapse of the pot life the material must be discarded and a fresh batch to be mixed.
Bonding / Priming
No primer required.
Mixed durafibre CFP adhesive should be pressed into place in the repair area using a small amount first to wet out the surface and then building up the required thickness. The viscosity of durafibre CFP adhesive is sufficient to hold its place in soffit and on vertical face repairs. If the volume is too large to repair in one application, leave the contact surface rough to act as a key for a subsequent placing once the first one has set.
A final smooth finish may be obtained by trowelling off the surface of the still uncured durafibre CFP adhesive with a water dampened steel trowel.
durafibre CFP (carbon fibre plate bonding)
Apply approximately 1 mm thick layer of durafibre CFP adhesive to the prepared concrete surface to enhance the bonding properties. This is followed by a layer on the cleaned ground side of the carbon fibre plate 2 mm thick tapering up to 4 mm along the centre line.
Temperature and Relative Humidity
durafibre CFW system should be applied at material temperatures between 12 °C and 18 °C and ambient temperatures of 5 °C to 30 °C. Temperatures should not fall below 5 °C in the 24 hours after application. Do not apply coating if the substrate temperature is at least 3 ºC (5 ºC is better) above dew point or highly humid conditions to cause condensation.
Theoretical coverage rates are provided in the “Properties During Application” table. The coverage rates may vary subject to surface profile irregularities and or porosity.
Consultation with a structural engineer is imperative when the design criteria and application configurations are required subject to load calculations of the various elements that are under consideration.

Health & Safety
Uncured durafibre CFP adhesive must be regarded as toxic. Gloves should be worn at all times and care must be taken not to ingest any of the material by eating or smoking while working with the compound. If working in a confined space, provide adequate ventilation. Cured durafibre CFP adhesive is inert and non-toxic.
Clean tools with abe® super brush cleaner while uncured and use a little of this liquid to remove any splashes on the skin. Wash finally with soap and warm water. Cured material will have to be mechanically removed.
durafibre CFP adhesive is supplied in:
2 litre kit (code: 20402002)
5 litre kit (code: 20402005)
Handling & Storage
Epoxy compounds in their uncured state are toxic and prolonged skin contact can give rise to dermatitis. When handling epoxy compounds, use should always be made of disposable gloves and barrier creams. Involuntary habits such as face starching and spectacle adjustment must be avoided. Similarly eating and smoking whilst or after working with epoxy must be avoided until the individual has washed up. This product has a shelf-life of 24 months if kept in a cool dry place.
