Mipa Rostversiegelung converts moisture in rust layers into carbon dioxide and thus cuts off the source of oxidation. The substrate gets cured and sealed. Loose rust must be removed by rough sanding. Mipa Rostversiegelung has an excellent penetration capacity also in thick layers of rust and stops also zinc corrosion. Shortly after the application the rust layers are already sealed and can be overcoated with Mipa 1K or 2K primer or Mipa body filler. Adhesion on iron, steel, aluminium and zinc
