Layering and advantages of flooring developed with Litotex Extreme cementitious adhesive thanks to the micro-design of the top interface of Litotex Extreme INSTALLATION ENVIRONMENTS: Covering Cementitious adhesive* approx. 4 Kg/m2 Interiors and exteriors Underfloor heating LITOTEX EXTREME Overlaying Terraces and balconies Industrial floors Residential, public, commercial building Cementitious adhesive* approx. 2.5 Kg/m2 Cement screed * Powerflex K50, Litoplus K55, Superflex K77 or Hyperflex K100 **compared to the amount of adhesive used for traditional dimpled membranes

Benefits it is ideal for outdoor paving, serving an excellent waterproofing function, while in indoor areas, it allows better management of joints, reduces noise and prevents the instability of surfaces. Vapour control The air channels in the structure of Litotex Extreme ensure the release of humidity coming from the substrate. Litotex Extreme is a valid solution for cracked or unstable substrates, avoiding the need to respect the joints, or for substrates that are not perfectly cured.
