LEVL Concrete Strong 7 — lithium impregnation for hardening concrete
Lithium silicate impregnation for dustproofing and hardening concrete floors and polished concrete; no organic solvents.

Skirtings, coves and other vertical and shaped elements of PoliCem systems are made with LEVL PoliCem PU 016, a thixotropic (non-sagging) compound. The material is applied with a trowel and a skirting trowel onto still tacky PoliCem PU 05 or 015 primer. Compressive strength is at least 25 MPa, flexural 10 MPa, bond to substrate 2.0 MPa; fire hazard class KM1, service from −40 to +90 °C with exposure to hot water. It is recommended for fish and meat processing and chemical laboratories.
