The corrosion protection of steel is usually done with a two layer coating of KOSTER Corrosion Protection, applied by brush or roller. The substrate preparation is carried out according to DIN EN ISO 12 944-4 (Sa 2 ½, RY5 > 50 μm).
If a crack bridging, flexible coating is required KOSTER Corrosion Protection is to be coated with two layers of KOSTER PUR-Bitumen.
In the case of extraordinary high acid impact (e. g. when underrunning the acid dew point) the entire coating is to be carried out with two layers of KOSTER VE. In addition to that KOSTER VE is suitable for covering edges, holes and screws prior to the application of KOSTER Corrosion Protection.
Always adhere to the specifications in the respective Technical Guidelines.
Because corrosion protection on steel requires experience and should be analyzed case by case, please contact our technical consultants. They will be glad to answer your questions.
