LEVL Self 12 — self-levelling underlayment for industrial coatings
Cementitious levelling compound for levelling concrete before laying polymer and cementitious floors; subsequent layers after 2–3 days.

LEVL Concrete Strong 7, a lithium silicate impregnation with 6.5 % non-volatile content, helps dustproof and harden a concrete floor without organic solvents. It is sprayed and spread with a microfibre mop after grinding; the product is used on ordinary concrete, for restoring topping floors and in “Mosaic” and “Terrazzo” polished concrete. The impregnation reduces abrasion and water permeability and increases resistance to aggressive media. Concrete must be at least class B20, with hardening completed.
