Rust Coat

DESCRIPTION:

AT-RUST COAT is a cement based polymer modified anti-corrosive protective coating formulated to inhibit the corrosion of reinforcing steel.

USES:

  • AT-RUST COAT is used in steel and concrete for protection from corrosion and carbonation. It is used in reinforcement with insufficient cover, corroded reinforcement in reinforced/pre-stressed concrete, repair of damaged concrete due to deicing salt effect, preventive protection of reinforcing bars, especially in slim reinforced concrete sections.

ADVANTAGES:

  • AT-RUST COAT is a two component cement bases polymer coating for steel. Key benefits are:
    • Easy to use, factory-proportioned kits.
    • Excellent adhesion to steel and concrete.
    • Good bonding coat for subsequent cement based repair mortar.

COVERAGE:

  • The average consumption of AT-RUST COAT is 3.6-4 kg/sq mt for 2 coats depending on the type of application.

APPLICATION:

  • The surface should be duly cleaned and the two components should be mixed in their proper mixing ratio (Comp A : Comp B = 1:4 by weight)
  • Before application, the surrounding concrete should be saturated surface dry.
  • Apply first coat approximately 1 mm thick on to the prepared reinforcement steel by using a medium stiff brush
  • It is unavoidable that AT-RUST COAT should be applied on to the surrounding concrete, which is by no means a disadvantage.
  • The second coat may be applied in the same method after waiting time of approximately 2 hours
  • The cement based mortars for repair, can be applied after the same time
