• Cost effective: Nitobond SBR (Latex) is economical to use 

• Nitobond SBR(Latex) is modified styrene butadiene 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 too. 

• Fosroc provides a technical advisory service supported by a team of specialists in the field.

• Typical mechanical properties of 1 : 3 cement sand mortar at W/C - 0.45 for control and W/C - 0.35 for mortar containing Nitobond SBR (Latex) ( 5 lites / 50 kg cement ). Tested in accordance with BS 6319 & wet cured.

Chemical resistance:

• Cementitious based materials have limited chemical resitance. The addition of Nitobond SBR (Latex) to cement mortars reduces permeability and therefore helps reduce the rate of attack by aggressive chemicals. 

• Surface Preparation: The object of the surface preparation is to achieve a clean sound surface with a good mechanical key. All substrates should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits, and any other deleterious substances. Laitence should be removed by mechanical means. Smooth substrates must be mechanically roughened e.g. by scabbling, needle gun or grit blasting to provide an adequate key.
• Corroded reinforcing steel should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is always preferably to clean the steel to a bright condition. Use of emery cloth, grit or sand blasting is recommended.

• Reinforcing steel must be primed with Nitozinc Primer immediately after cleaning. The concrete substrate should be thoroughly dampened with water and any excess removed before being primed by thoroughly scrubbing in a slurry coat of 1 volume Nitbond SBR (Latex) to 1 volume water to 3 volumes fresh cement.
• In order to obtain a smooth consistency the cement should be blended slowly into the liquids. Stir frequently during use to offset settlement.

Packaging:

• Nitobond SBR (Latex) is supplied in 1, 5 and 20 litre containers.

• Slurry primer: approximately 4- 5 m2 / litre depending on substrate porosity. 

• Shelf life: Nitobond SBR (Latex) has a shelf life of 12 months if kept in a dry store in unopened condition.

• Conbextra GP2 is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free flowing, non-shrink grout for gap thicknesses up to 100mm.
• Conbextra GP2 is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. The low water demand ensures high early strength. The graded fillers are designed to assist uniform mixing and produce a consistent grout.

• An experienced technical advisory team is available to give technical service on request.

Specification Clauses:

• Performance specification All grouting shown on the drawing must be carried out with a pre packed cement based product which is chloride free. It shall be mixed with clean water to the required consistency. The grout must not bleed or segregate. A positive volumetric expansion shall occur while the grout is plastic by means of gaseous system.

Typical detail of stanchion base plate:

• The compressive strength of the grout must exceed 50 N/mm2 at 7 days and 60 N/mm2 at 28 days.
• The flexural strength of grout must exceed 9N/mm2 @ 28 days. The fresh wet density of the mixed grout must exceed 2150 kg/ m3.
• The storage, handling and placement of the grout must be in strict accordance with the manufacturer's instructions. 

• Preparation Foundation Surface: The substrate surface must be free from oil, grease or any loosely adherent material. If the concrete surface is defective or has laitence, it must be cut back to a sound base. Bolt holes and fixing pockets must be blown clean of any dirt or debris.
• Pre-soaking Several hours prior to placing, the concrete substrates should be saturated with fresh water.
• Immediately before grouting takes place any free water should be removed with particular care being taken to blow out all bolt holes and pockets.
• Base Plate: It is essential that this is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots.
• Levelling Shims: If these are to be removed after the grout has hardened, they should be treated with a thin layer of grease.
• Formwork: The formwork should be constructed to be leakproof. This can be achieved by using foam rubber strip or mastic sealant beneath the constructed formwork and between joints.
• In some cases it is practical to use a sacrificial semi-dry sand and cement formwork. The formwork should include outlets for pre-soaking.

• As waterproofing agent: 2-5% of Nitobond AR Std. shall be mixed with concrete by weight of cement. 

Application instructions:

• Surface Preparation: The object of the surface preparation is to achieve a clean sound surface with a good mechanical key. All substrates should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits, and any other deleterious substances. Laitence should be removed by mechanical means. Oil or greasy deposits should be removed by suitable means. All surfaces so treated should be thoroughly washed with clean water. Smooth substrates must be mechanically roughened e.g. by scabbling, needle gun or grit/ sand blasting to provide a mechanical key.
• Concrete repairs: Any reinforcing steel in the repair area should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits and then primed with Nitocote AP35, acrylic primer. All surface dust and debris shall be removed.
• Priming: Immediately before priming, the concrete substrate should be thoroughly dampened with water and any excess being brushed off. Scrub Nitobond AR Std. bonding aid into the substrate. Puddling of the emulsion to be avoided. The repair mortar/topping should be applied whilst the primer is still tacky. However a satisfactory bond can be achieved upto 15 mins. after application at 300 C.
• In order to obtain a smooth consistency mortar, the cement and sand must be dry mixed and then poured into the liquid with the required amount of water in the prescribed mix proportions. 

Additional Guidance:

• Edges Shall be cut back to avoid feather edging and all surfaces including edges shall be primed using Nitobond AR Std. bonding aid.
• All applications shall be wet on wet. For best results Nitobond AR Std. bonding aid should be allowed to become tacky. If the bonding agent is allowed to dry for more than 15 minutes at 300 C initial 'grab' to the repair mortar will be reduced. Therefore, the use of temporary shuttering is recommended. Water content of the mortar should be kept to the minimum necessary.
• For consistent results, the use of clean, dry sand is recommended.
