Oxidher Sealant is formulated to paralyze the oxidation of any steel. For indoor or outdoor use. It prevents the appearance of rust on the floor during rain and when you touch the rust it will not stain your fingers as it will provide an impermeability to corten steel or metal coatings such as Oximetal, Metalplus or Metalresin. Its special formula creates a thin film barrier that reduces the normal crumbling of rusted surfaces and increases water resistance.
