Features & Benefits
- 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
- Improved tensile and flexural properties allow thin applications
- Excellent bond to concrete, masonry, stonework, plaster and blockwork
- Contains no chloride admixtures
- Can be applied to damp substrates
Uses
- For improving and bonding concrete repair mortars, floor toppings and screeds, waterproof renders and cementitious slurries
- Mortars and bonding slurries produced with Nitobond SBR may be used for horizontal, vertical and overhead repair work
- Suitable for permanent immersion
- May be used to form a bonding agent for slip bricks, ceramic tiles, etc
Application Notes
- Cementitious materials have limited chemical resistance. The addition of Nitobond SBR to cement mortars reduces permeability and therefore helps reduce the rate of attack by aggressive chemicals, acid gases and water
- Apply one full coat of Nitoprime Zincrich Plus to any exposed steel reinforcement
- A slurry primer should be prepared consisting of 1 volume Nitobond SBR to 1 volume clean water to 3 volumes fresh cement
- Where a substrate /repair barrier is required Nitobond EP bonding aid should be used
- Applicable by trowel
- A wide range of mix designs is achievable, see the Product Data Sheet for more details
- Where thicker sections up to a total thickness of 40 mm are to be built up by hand or trowel application, the surface of the intermediate layers should be scratch-keyed and cured with Nitobond AR
- The use of Nitobond AR or Concure WB, sprayed on to the surface of the finished mortar in a continuous film, is recommended
- Should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically
Limitations
- Nitobond SBR mortars, toppings and renders should not be applied when the temperature is below 5°C and falling
- The product should not be exposed to moving water during application
- Exposure to heavy rainfall prior to the final set may result in surface scour
- Nitobond SBR is non-flammable
