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

Pores, cavities and minor unevenness in concrete are closed with LEVL RemTixo Finish 5, a filler on Portland cement with polymer additives. It is applied with a trowel by hand or by machine; at +20 °C the mortar remains workable for at least 60 minutes, and subsequent layers are laid after 3–5 days. After 28 days compressive strength is at least 40 MPa, flexural 8 MPa, bond 2.0 MPa. Work is carried out at temperatures from +5 to +30 °C, optimally +15…+25 °C.
