LITSIL® H47 — potassium-lithium hardener for concrete and screeds
Aqueous solution of potassium and lithium silicates for low-grade concrete and cement-sand screeds that makes the surface 1.5–2 times stronger.

This membrane-forming lithium-based impregnation with hybrid polymers complies with ASTM C 309 and is suitable for both freshly placed and existing concrete. It cures fresh concrete, gives the surface a sheen, protects against oils and prevents efflorescence. It becomes tack-free and ready for the next coat in 1–2 h at 23 °C, and foot traffic is possible after 12 h. Apply at temperatures not below +7 °C.
