LITSIL® H47 — potassium-lithium hardener for concrete and screeds

Concrete impregnations and hardeners

This water-based potassium-lithium hardener is designed for low-grade concrete and cement-sand screeds, including substrate preparation for polymer coatings. It penetrates to 10 mm or more and increases surface strength by 1.5–2 times. The wet film is left for 30–40 minutes, and a pause of 8–10 h is recommended before further work.
