How to Use Nitobond SBR Latex

Nitobond SBR(Latex) is modified styrenebutadiene 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.

Nitobond SBR (Latex) is part of a wide range of adhesives, repair mortars, sealing compounds and fl flooring products specially designed and manufactured by Fosroc for the construction industry.

Surfaces to apply Nitobond SBR Latex

For modifying and improving bonding of floor toppings, renderings and mortars; repair of worn, damaged and spalled concrete, repair of large cracks; polymer modified floor screeds; waterproof plasters for masonry and slurries.

Surface Preparation before applying fosroc nitobond sbr latex

• All substrates should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits, and any other deleterious substances.
•  Smooth substrates must be mechanically roughened e.g. by scabbling, needle gun or grit blasting to provide an adequate key.
•  It is always preferably to clean the steel to a bright condition. Use of emery cloth, grit or sand blasting is recommended.
• The concrete substrate should be thoroughly dampened with water before the application.

Application instructions

• 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 off set settlement.
•  Minimum application temperature is 10 0C. For consistent performance the use of clean, dry sand is recommended. Where wet sand is   used, reduce the added water level as appropriate.

Benfits:

•  High – Provides excellent bond to concrete, adhesion plaster, masonry, stone work, etc
•  Reduces – Provides waterproof screeds, plasters and Permeability slurries.
•  Increases – Improved tensile and fl exural properties strength allow thin applications.
•  Versatile – Compatible with all common hydraulic cements.
•  Cost eff ective – Nitobond SBR (Latex) is economical to use.

Health & Safety instructions while applying SBR Latex

• Health & Safety instructions Nitobond SBR (Latex) should not come in contact with skin and eyes or be swallowed.
•  Protective gloves and goggles should be worn.

Cleaning Tools and equipment should be washed with water mmediately after use.
