1 Nitobond ARconstructive solutions Registered Trade mark of Fosroc International ARAcrylic emulsion cement modifier and water basedconcrete bonding agentUsesRecommended primer for Fosroc cementitious repairsystem. For improving and bonding floor toppings, rendersand mortars; repair of worn, damaged or spalled concrete;polymer modified floor 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 flexuralproperties of mortar.

2 Allows thin section applications. Versatile - Compatible with all commonhydraulic cements Economical - Economical to useDescriptionNitobond AR is a modified acrylic emulsion speciallydesigned for use as a bonding aid and gauging liquid forcementitious systems. It is resistant to hydrolysis and cantherefore be used for external AR is the recommended primer for the Fosroccementitious repair supportFosroc offers a technical support service to specifiers, endusers and contractors, as well as on-site technical assistancein locations all over the propertiesTypical improvements in mechanical properties of a 3.

4 The bonding agentshall provide adequate bond strength when directly appliedon concrete and also mixed with neat a mortar modifierThe mortar modifier shall be Nitobond AR, an acrylic emulsifiedcement modifier which provides good bond with concrete /masonry and improves the flexural strength, tensile strengthproperties of the mortar when added in the specified shall be compatible with all common hydraulic instructionsSurface PreparationThe object of the surface preparation is to achieve a cleansound surface with a good mechanical key. All substratesshould be cleaned and free of dust, plaster, oil, paint, grease,corrosion deposits, and any other deleterious should be removed by mechanical means.

5 Oil orgreasy deposits should be removed by suitable means. Allsurfaces so treated should be thoroughly washed with cleanwater. Smooth substrates must be mechanically by scabbling, needle gun or grit/ sand blasting to providean mechanical repairs : Any reinforcing steel in the repair areashould be exposed around its full circumference and cleanedto remove all loose scale and corrosion deposits and thenprimed with Nitozinc Primer. Remove all surface dust before priming, the concrete substrate shouldbe thoroughly dampened with water and any excess beingbrushed off.

6 Scrub Nitobond AR into the substrate. Avoidpudding of the emulsion. The repair mortar/topping shouldbe applied whilst the primer is still tacky. However a satisfactorybond can be achieved upto 15 mins. after application at Mix designs to modify mortars :OPC50 kgZone 2 sand150 kgNitobond AR8 - 10 litresNitobond ARWaterAdd sufficient water togive required consistencyNote : Trials are recommended to optimise mix recommendationsFor repairsPrepare surfaces thoroughly as previously recommended Cutback edges to avoid feather edging. Prime all surfacesincluding edges, using Nitobond applications shall be wet on wet.

7 For best results NitobondAR should be allowed to become tacky. If the bonding agent isallowed to dry for more than 15 minutes at 300 C initial 'grab' tothe repair mortar will be reduced. Therefore, the use oftemporary shuttering is recommended. Water content of themortar should be kept to the minimum consistent results, the use of clean, dry sand isrecommended. Where the use of wet sand is unavoidable,the quality of water to be added must be mortars using Nitobond AR to prevent rapid drying uncured mortar from frost and rain. Do not retempermortar after initial application temperature for Nitobond AR is 100C,but the mortar should not be applied if the temperature isexpected to permanently immersed conditions consult Local a bonding agentNitobond AR may exhibit less overlay time at highertemperature.

8 In such cases as overlay mortar shall not beapplied when Nitobond AR is totally AR when used as bonding agent cannot act as abarrier coat against ingress of chloride ions from the cleaningImmediately after use, wash all tools with clean AR is supplied in 1, 5 and 20 litre plastic 6 - 8m2/ litre depending on substrateStorageShelf life6 months at 300C. Nitobond AR should be protected from & Safety instructionsNitobond AR is non toxic.
