For rust removal and corrosion protection of surfaces of steel structures that have not been entirely cleaned before painting. TOP-KOR is particularly recommended for use before renovation painting of fences, gates, gratings, railings, roofs, elements of motor vehicles and other structures made of steel, galvanised steel and cast iron. TOP-KOR features triple action: rust removal (it processes and binds rust), barrier effect (it creates a barrier for oxygen and moisture, which protects against future rusting) and penetrating effect (it penetrates into places difficult to reach and protects such places).

When applied to rust-coated iron substrates, TOP-KOR forms a stable film that remains resistant to further oxidation, thus ensuring long-term corrosion protection. It also protects gaps, pores and cracks in substrates against corrosion.
