Polysil TG500 acts as a primer for mineral substrates prior to application of cementitious waterproofing slurries. In the case of masonry restoration, this 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. On moist substrates that have a high salt content, it causes a reduction of the pore volume and thereby prevents the renewed formation of salt efflorescence.
Consumption = approx. 0.1 - 0.13 kg/m² depending on substrate, approx. 0.2 - 0.25 kg/m² for hardening of slurries
