One example of the need for heavy duty corrosion protection against acidic fumes and condensate is the coating of industrial chimneys made of concrete or masonry.
For the restoration of concrete or masonry, the substrate is to be mechanically cleaned until a solid, unburdened substrate is achieved. The surface is primed with KOSTER Polysil TG 500, which hardens the substrate and immobilizes salts.
Reprofiing is done with KOSTER Repair Mortar NC. The surface is roughened in order to achieve a strong mechanical bond to the surface with KOSTER PSM.
KOSTER PSM is applied as the protective layer against acids.
Always adhere to the specifications in the respective Technical Guidelines.
