LITSIL® H25 — concentrate for hardening weak and old concrete
Lithium concentrate with 23 % active content for old, friable concrete and semi-dry screeds with a strength of at least grade M100.

What sets this impregnation apart in the range is its violet colour: on fresh concrete you can see at once which areas have already been treated. The lithium-based product is sprayed from a distance of 30–60 cm ahead of the power trowel and trowelled in immediately; no washing off is required. The impregnation gives up to 30 minutes of extra trowelling time. It is suitable for workshops, warehouses and car parks; work is carried out at +4…+35 °C.
