TREATMENT OF CORRODED (RUSTED) STEEL REBARS

by Sunanda g. SUNANDA SPECIALITY COATINGS PVT LTD

It is a well-known fact that corrosion of steel reduces the service life of structures. Once steel rebars start corroding (rusting), the reinforced concrete structure begins deteriorating. 

Well, Guess What?

Sunanda Global has developed and created a miracle product called RUSTICIDE, a single component sulphate and chloride-free liquid, which in one operation removes rust and prevents further rusting of steel. It’s the complete solution to treating corrosion of steel bars.

ADVANTAGES 

RUSTICIDE is a rust remover liquid for steel that treats corroded rebars in one operation.  

APPLICATIONS 

Rusticide is a rust remover and passivator and prevents further corrosion of 

  • New/ old reinforcement steel. 
  • Embedded steel in repairable structures. 
  • Steel structures such as tanks, water pipelines, effluent pipelines, trusses, purlins, rafters, and other structural members.

Simple Methodology To Use Rusticide:

  • Initially remove loose rust by mechanical means like wire brushing, chipping, hammering, etc. depending on the extent of corrosion. 
  • Apply sufficient RUSTICIDE on the affected metal surface using a cotton waste swab.
  • Leave it in contact with the surface until the red color of the corroded steel surface gets converted to the nearest original black.
  • An excess application may sometimes give a whitish black surface.
  • Remove the freed loose rust particles by brush after a minimum duration of 24 hours. 
  • The reddish rusted surface is still left exposed sometimes after the detachment of loose scales. This should be re-treated with RUSTICIDE.
  • A passivating coating like POLYALK FIXOPRIME may be applied after the surface totally dries up (around 48 hours later) as per specification.
