Adirepar Pasivator

Pre-dosed cement-based mortar with corrosion passivating additives, fast hardening and enhanced with synthetic polymers, used for the protection of concrete reinforcement against corrosion due to the fact that it establishes a basic pH in the medium in which it is applied and as a bonding bridge prior to the application of repair mortars. It also acts as a bonding bridge between the reinforcement and the applied repair mortar.

Mortar with corrosion inhibitor additives used for the protection of all types of reinforced concrete structures, both curative and preventive in applications in aggressive environments (freeze-thaw cycles, contaminated environments), extending the life of the reinforcements. Used in carbonated concrete with corroded or chloride-contaminated steels, pillars, beams and floor slabs. Suitable for marine works, sewage treatment plants.

  • Preparation of the substrate:

 

  • The concrete substrate must be fully cured, resistant, consistent, dry, clean of dust, paint, oil, etc. and free of any traces of release agent.
  • The reinforcement must be clean, free of rust and possible remains of concrete.
  • The reinforcement must be cleaned over its entire surface with the aid of a wire brush or sandblasting.
  • Vacuum the dust resulting from the cleaning of the concrete and reinforcement.

 

  • Preparation of the mixture: Add 5.2-5.6 litres of water per bag and mix with an electric mixer at low r.p.m. until a homogeneous, lump-free paste is obtained, leave the paste to stand for approximately two minutes and stir until a fluid dough texture is obtained.

 

  • Application of the paste: Apply a first coat of ADIREPAR PASIVADOR of approximately 1 mm manually with a roller or brush. Leave to dry for 3-4 hours (dry to the touch) and apply a second coat of the same thickness to achieve the most homogeneous coverage of the reinforcement possible.

 

  • The application temperature must be between 5 °C and 35 °C in air and between 5 °C and 25 °C on the substrate.
  • Do not apply if frost is expected or in full sun.
  • Shake periodically to extend the pot life of the paste to its optimum.
  • In case of rain do not apply the product on exposed areas.
  • In case of loss of fluidity and texture that makes the application difficult, add 1% by mass of water and re-mix.
