LEVL Concrete Strong 12 — lithium silicate impregnation for concrete floors
Hardening and dustproofing lithium silicate impregnation with 11 % non-volatile content for concrete, topping and polished floors.

The economical version of the epoxy self-levelling floor, LEVL Coat 308, is never used without mineral filler: quartz sand is added to the mix at a ratio of 1 : 0.5, up to 1 : 1 permitted. The result is filled and highly filled, smooth or textured coatings; laying is carried out at temperatures from +15 to +30 °C over LEVL Coat epoxy primers. Compressive strength is at least 55 MPa, flexural 25 MPa, Taber abrasion up to 55 mg. Applications: offices, retail, healthcare, warehouses, workshops, garages, car parks and rooms with a “wet cycle”.
