4.01 - KÖSTER Polysil® TG 500 A primer for mineral substrates before waterproofing with cementitious waterproofing slurries. In case of masonry restoration the product is used during substrate preparation for restoration plaster systems in order to harden the substrate and immobilize salts. Also suitable for the additional hardening of waterproofing slurries. KÖSTER Polysil® TG 500 is a low viscous, substrate solidifying, hydrophobizing combination product on a polymer / silicate basis for the protection of mineral substrates.
