In the earlier article, we discussed how Rusticide helps in the removal of rust from steel.
Now once the corrosion (rust) has been treated using Rusticide, it is necessary to prevent it from rusting thereafter to ensure that the structure can meet its designed service life.Sunanda Global has exactly developed a tailormade ready-to-use product - POLYALK FIXOPRIME.
The high alkalinity of cement fortified by high alkalinity, high flexural strength, and extra adhesion owing to specially engineered polymers in POLYALK FIXOPRIME, give long-lasting protection against corrosion (rusting) of steel rebars.
Being cementitious, Polyalk Fixoprime coated rebars do not suffer the loss of a bond when embedded in concrete, whereas epoxy-coated bars are prone to suffer substantial loss of bond.STEPS TO USE POLYALK FIXOPRIME Clean the steel surface with a stiff wire brush to remove loosely held rust particles/ scales.
Apply RUSTICIDE with cotton waste swab as per specification.
Mix 1 Kg of POLYALK FIXOPRIME with 1.25 Kgs of fresh grey cement, using a mechanical stirrer, to form a lump free slurry Apply this slurry to the steel rebar surface with a brush taking care to avoid pinholes.Allow this coat to set for a minimum of six hours (or preferably till the next day) Apply a second coat of the slurry carefully and allow this coat to set.
