LITSIL® H15 — lithium silicate hardener for existing and polished concrete

Concrete impregnations and hardeners

The core product of the range for decorative polished concrete is an aqueous solution of lithium polysilicates with 15 % active substance, free of volatile organic compounds. It is used on existing concrete floors in workshops, warehouses, car parks and retail halls. Depending on the hardness of the concrete, it is diluted with water at 1:0.5–1:1, and the excess is removed after 30 minutes. ASTM tests show an increase in Taber abrasion resistance of 20–50 % and in pull-off strength of 25–75 %.
