Parex SBR Liquid – waterproofing and bonding admixture
Parex SBR Liquid – waterproofing and bonding admixture. SBR Liquid is a milky white latex based on a modified styrene butadiene copolymer emulsion. The resulting product is a waterproofing and bonding admixture. SBR Liquid can be mixed with cements, sand-cement mortars and concretes. The mixes produced give high bond strength to existing concrete, masonry and reinforcing steel. Weather resistance is improved due to reduced permeability and thinner sections may be applied due to improved flexural and tensile strengths. Additional improved properties include abrasion resistance, freeze thaw resistance and chemical resistance.
- Concrete repairs
- Floor toppings
- Bonding of screeds and renders
- Waterproofing of tanks and pools
SBR Liquid is suitable for both internal and external use.
SBR Liquid as manufactured by Parex Ltd should be used as the gauging liquid for cementitious mixes. Water may be added to the mixes to adjust workability. The product must be stored, handled and placed strictly in accordance with the manufacturer’s instructions.
Mixing- Mixing should be carried out in a forced action mixer such as the Cretangle or Mixal. Add the cement and sand, plus aggregate if required, to the mixing pan and dry premix. Add the SBR Liquid and mix for 1-2 minutes. Add water slowly until the required consistency is achieved.
Placing – SBR Liquid mixes should be placed within the following section thicknesses.
Concrete repair mortar 5 – 40mm
Grano floor screeds 12 – 35mm
Floor screeds 10 – 40mm
Renders 5 – 15mm
Plasters 3 – 15mm
Water resistant bricking mortars 5 – 20mm
Substrates should be thoroughly dampened before application of the SBR Liquid slurry primer. The slurry primer must not be allowed to dry before the application of the topping mix. Only prime sufficient area to ensure primer is wet enough to receive the topping.
Curing – Applied topping mixes should be cured in accordance with good concrete practice including water-spray, polythene sheeting and spray applied curing membrane
All product information and instructions for use can be found on the technical datasheet.
