Nitobond® AR(STD)

Nitobond® AR(STD) is a modified acrylic emulsion specially designed for use as a bonding aid and gauging liquid for cementitious systems. It is resistant to hydrolysis and can therefore be used for external applications. Nitobond AR is the recommended primer for the Fosroc cementitious repair system.


Simply brush onto concrete as a primer. Single component, gauged as required.

  • High adhesion -Provides excellent bond to concrete, masonry, stone work plaster and block board.
  • Increased strength – Improves tensile and flexural properties of mortar. Allows thin section applications.
  • Versatile – Compatible with all common hydraulic cements.
  • Economical – Economical to use.
  • Increase durability of concrete by reducing water permeability.
  • Chloride free, hence safe for reinforced concrete.
  • For improving and bonding floor toppings, mortars and renders.
  • As a bonding agent for Renderoc and other cementitious mortars.
  • Polymer modified mortars and screeds for reinstatement of worn out/damaged concrete.
  • Polymer modified concrete for improving the impermeability and there by enhancing the waterproofing property.
  • Good adhesion – Provides good bond to concrete, masonry, stone work, plaster and block work.
  • Increased strength – Improves tensile and flexural properties of mortar.

As a cement modifier

Approximately 6 – 8m2/ litre depending on substrate. 21kg of mixed polymer mortar ( 1 part polymer, 5 parts cement & 15 parts quartz sand) will yield approximately 10 -11 litres.

As a bonding agent

Approximately 3 – 4 m2/litre* depending on substrate conditions. (* 0.5 part cement : 1 part of Nitobond AR Std. by weight.

As waterproofing agent

2-5% of Nitobond AR Std. shall be mixed with concrete by weight of cement.



Nitobond AR Std. bonding aid is supplied in 1, 5 and 20 litre plastic containers.
