Feb® Febond® SBR

Waterproofer and Bonding Admixture designed for use with cementitious mixtures

Feb® Febond® SBR is a styrene-butadiene co-polymer latex specifically designed for use with cementitious mixes and as a reliable water resistant bonding agent. It is used in mortar and concrete as an admixture to increase water and abrasion resistance and durability. Ideal for concrete repair.

  • Greatly increased flexural strength.
  • Tensile strength increased.
  • Greatly reduced shrinkage (with appropriate aggregate).
  • Prevents bleeding.
  • Lower water-cement ratio.
  • Increased durability and toughness, improved abrasion resistance.
  • Good frost, abrasion resistance and resistance to water-borne salt penetration.
  • Resistant to many chemicals and to mineral oils.
  • Excellent adhesion to steel and concrete. Sticks well to brick, glass, asphalt, wood, expanded polystyrene and most building materials.
  • Enhanced corrosion protection.
  • Proven performance.
  • Similar thermal expansion and modulus properties to concrete.

Application

Consumption

Yield

When using as a bonding coat 1 litre of Feb® Febond® SBR will typically produce enough slurry to coat 3 square metres of substrate dependent on surface texture and thickness applied. For all normal use the standard dose of 10 litres of Feb® Febond® SBR per 50 kg Portland Cement is adequate. For extreme conditions and/or where adhesion, waterproofing, water vapour resistance or chemical resistance are critical, the dosage should be increased to 15 litres of Feb® Febond® SBR per 50kg Portland Cement. For this higher dosage, the extra water addition required is low and, therefore, use of wet aggregate may result in excessive workability.
Application steps

SUBSTRATE PREPARATION

Surfaces to which Feb® Febond® SBR mixes are to be applied should be clean, sound and free of deleterious substances. When repairing spalled or damaged concrete, ensure that the concrete has been cut back to thoroughly sound material. Always lay to a minimum 6mm deep saw cut edge, depending upon application. Avoid ‘feather edging’.

Bonding Slurry

Wet down absorbent surfaces, such as concrete and brick, so that they are damp but surface dry when the bonding slurry is applied. Prepare a bonding slurry of approximately 1.5 parts of OPC to 1 part of Feb® Febond® SBR by volume. The normal method of application is by stiff brush scrubbing well into the surface, taking care to ensure complete coverage. A typical single slurry coat has an average thickness of 0.3 to 0.5mm and thickness’ significantly above this should be avoided. If a second coat is necessary it should be applied at right angles to the first. Never apply more than can be comfortably over-screeded/rendered within 15 minutes.

MIXING

Mixing should preferably be carried out in a forced action mixer, a Crete angle is recommended. Hand batching is only permissible when the total weight of the mix is less than 25kg. Charge the mixer with the required quantity of sand and cement and pre-mix for approximately one minute. Pour the desired quantity of Feb® Febond® SBR and mix for about 30 seconds only, to minimise air entrainment. Slowly add water, whilst still mixing, until required consistency is obtained. (Stop mixer when testing consistency). The total mixing time after adding the Feb® Febond® SBR should not exceed two minutes. Owing to the strong plasticising properties of Feb® Febond® SBR, rapid thinning can occur - avoid adding excessive water.
