Bond Coat

DESCRIPTION:

AT-BOND COAT is a synthetic based bonding agent which provides good adhesion and water resistance.

STANDARDS:

AT-BOND COAT as a bonding agent complies with ASTM C1059

USES:

  • AT-BOND COAT is use to bond old to new concrete
  • Topping patches and leveling mortar
  • Concrete repair and adhesive mortar
  • As an admixture in cement injection mix etc.

ADVANTAGES:

  • AT-BOND COAT is a highly effective multipurpose styrene butadiene rubber (SBR) admixture for bonding, waterproofing & repair. Key benefits are:
    • Easy to use
    • Non – toxic
    • Increases the mechanical strength of the mortar
    • Makes the mortar waterproof
    • Extremely good bonding to bases like concrete, stone grout etc.
    • Reduces viscosity of cement injection grout

INSTRUCTION FOR USE:

  • SURFACE PREPARATION
    • Before application of AT-BOND COAT check that surface(s) should be clean from loose particles, dust, oil, grease, acids, and other organic solvents. Absorbent surfaces should be thoroughly saturated with water.
  • APPLICATION
    • Prepare a consistent mortar with AT-BOND COAT, cement and sand in the ratio of 1:1:2 by volume.
    • Water may be used to achieve desired consistency for brush application.
    • Apply the mortar onto the surface of the old concrete. Pour fresh concrete after an hour of application of the bond coat.

COVERAGE:

  • The coverage depends on the type of the surface.
    • Approximately 3-4 sq.mtr. of area is covered by 1 kg of AT-BOND COAT
