LITSIL® H29 — chemical hardener for low-grade concrete and screeds
Water-based impregnation for low-grade concrete, cement-sand screeds and terrazzo floors; the surface becomes 1.5–2 times stronger.

This drying retarder for freshly placed concrete forms a monomolecular film on the surface. This extends the open time for finishing and reduces the risk of cracking when working in wind, sun and at temperatures above 24 °C. The concentrate is diluted with water at 1:9 and sprayed. The product is not a membrane-forming curing compound under ASTM C 309.
