The cover fleece FLOORLINER™ original (Swiss-made) is laminated on the upper side with PE film as a liquid barrier, and on the underside with an anti-slip OPTICOAT™ coating, thus helping to prevent accidents and ensuring a clean and safe construction site. Never use on wet and freshly laid floor coverings. The covering grounds as well as the material must be dry and clean. Chemical evaporation must be completely stopped. Failure to do so may result in stains and sticking. Not suitable for freshly installed natural stone and slab floors, or freshly treated parquet floors. Always try on a concealed area first.
