Koster Polysil TG 500 per 2.56 gallon unit

Koster Polysil TG 500

KOSTER Polysil TG 500 is a thin film forming polymer/silicate-based liquid. On salt-containing or damp substrates, it reduces the pore volume and reduces the development of salt efflorescence. It also increases the chemical and mechanical bond strength of cementitious building materials. Depending on the substrate, the product penetrates up to a depth of ¾”.

KOSTER Polysil TG 500 has strengthening and hydrophobing properties. The material is compatible with mortars, screeds, cement-based slurries as well as concrete substrates.

Fields of Application

KOSTER Polysil TG 500 is used to strengthen, protect, and reduce the absorption of cement-based substrates, even with problematic materials. KOSTER Polysil TG 500 decreases the risk of new development of salt efflorescence and raises the resistance of cementitious substrates to freeze/thaw cycles. Do not install over gypsum based materials. KOSTER Polysil TG 500 can also be used to harden sealing slurries. It does not cause surface crusting. KOSTER Polysil TG 500 can be used as a primer between layers of polymer modified bitumen thick film sealants such as KOSTER Deuxan 2C and KOSTER Bikuthan 2C.
