LITSIL® H42 — lithium silicate hardener with dirt protection for concrete

Concrete impregnations and hardeners

This lithium hardener offers additional protection against dirt: besides hardening, it reduces the water absorption of concrete. The manufacturer recommends it for outdoor areas as well as for workshops and warehouses. The base is an aqueous solution of lithium polysilicates with 12 % active content; it is applied at temperatures not below +5 °C. Taber abrasion resistance to ASTM D4060 rises by 20–50 %.
