Köster Polysil® TG 500 – Anti-lime
Deeply penetrating primer for damp, salt-containing substrates and an anti-lime treatment for new concrete. Also a liquid hardener for sealing slurries.
KÖSTER Polysil® TG 500 anti-lime is a thin fluid product based on a polymer and silicate combination. On salt-containing and on damp substrates, it leads to a reduction of the pore volume and thus decreases the danger of new development of salt efflorescence and free lime egress. It also increases the chemical and mechanical resistance of mineral building materials. Depending on the substrate, the product penetrates the surface up to 2 cm deep. KÖSTER Polysil® TG 500 also has strengthening and hydrophobing properties. The material is compatible with mortars, plasters, cementitious slurries and with concrete.
Field of application
KÖSTER Polysil® TG 500 is used to strengthen and to protect mineral substrates and to reduce their absorbency, even of such problematic building materials as sandstone. KÖSTER Polysil® TG 500 decreases the danger of new development of salt efflorescence, free lime egress, and raises the resistance of mineral substrates to freezing and thawing. KÖSTER Polysil® TG 500 can also be used to harden sealing slurries. It does not cause shell building. All mineral substrates are suited for application (except for gypsum). Furthermore, KÖSTER Polysil® TG 500 anti-lime can be used as primer underneath subsequent layers of polymermodified bitumen thick film sealants such as KÖSTER Deuxan® 2C, KÖSTER Bikuthan® 2C and so on.View Data Sheet Watch Video Guide
