Description

Resbuild SBR – Co-polymer emulsion

Resbuild SBR – Co-polymer emulsion which imparts beneficial property improvements to cementitious mixes. After appropriate dilution with water, the resultant liquid may be used to gauge the cementitious mix to the desired consistency. A reduced water to cement ratio leads to superior mechanical properties and resistance to moisture ingress.

• Plasticising action
• Waterproofing action
• Improves adhesion
• Reduces permeability
• Increases mechanical strength
• Up-grades chemical resistance
• Versatile and easy to use
• Cost effective
• Improves freeze-thaw resistance
• Compatible with many types of cement

Uses

• Flooring: screeds and patch repairs in dairies, abattoirs, breweries, factories, etc.
• Bonding additive: renders, slip bricks, tiles, coping stones, etc.
• Concrete repair: making good structural concrete, increase in effective concrete cover.

Surface Preparation – Substrates shall be clean, sound and free from contaminants such as oil, grease, moss, algae, dust and any existing loose or flaking paintwork.

Priming – Surfaces shall be pre-dampened with clean, potable, water, taking care to remove any excess surface water. A 1:1 cement/sharp sand mix should be gauged to a slurry consistency using a 1:1 Resbuild SBR/Water blend. This bonding slurry shall be brushed onto the prepared surface using a stiff brush.

Note: in certain instances it may be deemed preferable to prime with an Epoxy bonding agent such as Resbuild Tackprimer. In such an event the Resbuild Tackprimer should be applied to a dry substrate and be allowed to ‘tack up’ prior to topping. Please refer to the Resbuild Tackprimer product data sheet for additional information.

Polymer modified cementitious toppings – The appropriate design mix material shall be applied
whilst the primer is still tacky, and finished and cured in accordance with good concreting practice. Mix designs can be found on the technical datasheet.
