Description:
Nitobond SBR/SBR Latex is a modified styrene butadiene rubber emulsion which is supplied as a ready to use white liquid. It is designed to improve the qualities of site-batched cementitious mortars and slurries. Being resistant to hydrolysis, it is ideal for internal and external applications in conjunction with cement.
Nitobond SBR/SBR Latex has a VOC content 29g / litre.

Uses:

For improving and bonding concrete repair mortars, cementitious floor toppings and screeds, waterproof renders and cementitious slurries. Cementitious mortars are alkaline in nature and will protect embedded steel reinforcement. Mortars produced with Nitobond SBR may be used for horizontal, vertical and overhead repair work.

Advantages:

  • Excellent bond to concrete, masonry, stonework, plaster and blockwork
  • Improved tensile and flexural properties allow thin applications
  • Single component liquid can be easily gauged as required
  • Improves cohesion and workability
  • Improves mortars to provide waterproof repairs, renders and toppings which are highly resistant to freeze/thaw cycling
Area of Application:
For modifying and improving bonding of floor toppings, renderings and mortars; repair of worn, damaged or spalled concrete; repair of large cracks; polymer modified floor screeds; waterproof plasters for masonry and slurries.

Limitations:
Nitobond SBR mortars, toppings and renders should not be applied when the temperature is 5°C and falling. Neither should they be exposed to moving water during application. Exposure to heavy rainfall prior to the final set may result in surface scour. If any doubts arise concerning temperature or substrate conditions, consult your local Parchem sales office.

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. 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.

Priming

Reinforcing steel must be primed with Nitozinc Primer immediately after cleaning. The concrete substrate should be thoroughly dampened with water and any excess water removed before being primed by thoroughly scrubbing in a slurry coat of 1 volume Nitbond SBR 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 off set settlement.

Avoid ‘puddling’ of the slurry coat. The topping must be applied on to the wet slurry. If the slurry dries out it must be removed and the clean substrate reprimed.

Cleaning:-

Tools and equipment should be washed with water immediately after use.  

Additional Guidance:-

Prepare surfaces thoroughly. Toe-in at edges wherever possible to avoid feather edging.

All surfaces including edges must be primed.
