Acrylic based bonding agent for cementitious repair mortars

Polybond AC is a single component, acrylic polymer based emulsion, designed as an admixture for cementitious mortars and screeds and as a bonding and curing agent for concrete and patch repairs.



  • Improves bond, compressive and tensile strength of cementitious mixes
  • Reduces the permeability of mortar
  • Single component, easy to apply
  • Suitable for internal and external application


Surface to which Polybond AC mixes are to be applied should be clean, sound and free of loosely adhering material. Remove all laitance, oil, grease, mould oil or curing compound from concrete surface using wire brush, bush hammer or by blasting. Ensure that reinforcing steel is clean and free from scale and rust. When repairing damaged concrete, ensure that the concrete has been cut back to thoroughly sound substrate. 


Wet down absorbent surfaces, such as concrete, brick, stone, ensuring that they are fully saturated but free of surface water. Prepare a bonding slurry of 1 to 2 parts cement to 1 part of Polybond AC mixed to a lump- free creamy consistency. Using a stiff brush, work the bonding slurry well into the damp surface, ensuring that no pinholes are visible. Do not apply bonding slurry at a thickness in excess of 2mm. If a second coat is necessary, it must be applied at right angles to the first coat to ensure complete coverage.


Polybond AC Standard dose is 5-8L per 50 kg of cement used. For more demanding situations, and greater exposure to aggressive environment 15L per 50 kg of cement is recommended. Mixing should be carried out in an efficient concrete mixer. Charge the mixer with required quantity of sand and cement and premix for approximately one minute. pour the required quantity of Polybond AC and mix for two minutes only to avoid excessive air entrainment. Add the water slowly until the required consistency is achieved. avoid adding excessive water. 


Apply the bonding slurry to the prepared surface and then render immediately with Polybond AC modified mortar. Apply in coats to a maximum thickness of 5mm per coat. Several coats can be applied at intervals of 20–30 minutes. Thicker coating can be applied when suitable form work is used. finish the surface using wooden float or steel trowel.


Proper curing of Polybond AC modified mixes is vital. Small patch repairs can be cured with Polybond AC. Large areas should be cured by resin based curing compounds, wet hessian or water mist methods.
