Abstract
The invention relates to a method for laying a floor covering that includes a flexible material containing a thermoplastic wear layer made from, in particular, plasticized PVC. The basic panels that form the covering are glued to the ground and cold welded in between on the site to be covered. After a panel has been positioned and glued to the surface to be covered, a continuous bead of mastic, which is made on the actual site by mixing a hardener and a polyurethane resin in aqueous phase, is applied laterally along the entire depth of the covering. The next panel is positioned on the ground which is covered with adhesive and the lateral edge thereof is pinned against the edge of the preceding panel comprising the bead of mastic, thereby causing the excess material to come to the surface, where it is removed by simply wiping with water.
