NAFUFILL BBR STD

Properties:

• Provides an efficient adhesion and bonding of mortars, concrete, and plaster to old hardened concrete or mortar bases
• Nafufill BBR STD admixed mortars are easy to work with and can be drawn to very thin layers
• Nafufill BBR STD increases the elasticity of the mortars and concretes and therefore prevents the formation of stress cracks in the hardened and set mortars or concretes
• Nafufill BBR STD increases the resistance of the screeds, plasters, and concrete against attack by oils

Applications:

• Waterproofing mortars and slurries
• Repair and patching mortars for efficient repairs of screeds, steps, and similar damages on concrete and mortar surfaces
• Leveling and smoothening mortars for thin-layer applications
• Mortars to bond tiles efficiently to walls and for laying tiles on floors using thin-bed method
• Bonding slurry between hardened concrete and fresh toppings of concrete or mortars
• Repair mortars for mending damaged spots in the precast concrete industry, pipelines, etc.
• Dado mortars subjected to high wearing and exposed to water
• Bonding mortars for bonding for hard-burned bricks, asbestos cement, natural stones, tiles, etc.
• Cement screeds, gypsum and lime plaster

General:
Nafufill® BBR STD is a high quality; saponification resistant, liquid SBR latex dispersion for improving adhesion and strengths of all types of commonly used mortars. It is suitable as an admixture for concrete, cement mortars, lime and gypsum mortars for obtaining waterproof concretes and mortars.

The addition of Nafufill® BBR STD to mortars improves the bond between the old surface and the new mortar, increases resistance of the toppings against wear and renders the mortars watertight. Additionally, it improves the workability and water retaining capacity of the mortars. All these extraordinary properties of Nafufill® BBR STD promote it to be an indispensible aid for all types of mortars made from cement, lime and gypsum plasters and concrete.

Application Surface:
Preparation The base should be clean, free and loose materials and dust. It should also be free from oils, fats, and similar contaminations. The prepared bases should be slightly wet before the application of forthcoming layers.

In case of smooth or uneven bases it is advisable to apply a coat of Nafufill® BBR STD admixed slurry. The following proportions are recommended for the preparation of the slurry, one part of standard cement to one part of clean sharp sand of grading 0/1 mm should be dry mixed. Nafufill® BBR STD should be added undiluted to the dry mix. This mixing liquid should be added to the dry mix until slurry is obtained. This type of application of Nafufill® BBR STD is an example for usage of Nafufill® BBR STD admixed mortars and plasters. Depending upon the nature of the individual requirements Nafufill® BBR STD can be mixed with almost all types of mortars and concrete where a good bonding and even finish are required criteria.
