LITSIL® H42 — lithium silicate hardener with dirt protection for concrete
Lithium polysilicate impregnation that hardens concrete, reduces water absorption and protects against dirt, including on outdoor areas.
This two-component polymer compound is mixed at a ratio of 1:1 by volume and used to repair joints, cracks, spalls and potholes in concrete, terrazzo floors and toppings. The material is used neat or with a filler — cement, mineral slurry or sand — and does not shrink. At 20 °C, its pot life is only 3 minutes and hardening takes 30–40 minutes. The substrate must have reached at least 70 % of its grade strength, and the temperature must be not below +10 °C.
