  • Patent number: 4879143
    Abstract: A process for the production of floor covering, especially of the floating type for private and public areas, wherein a granulated material is mixed with a hardenable plastic binder to a paste-like mass, this mass being subsequently spread evenly on a surface, smoothed and then hardened. The grain size of the granulated material and/or the mixing proportions between the granulate and the binder are so selected that after the application and smoothing of the mass, neighboring granules of the granulated material are basically touching each other only in certain points, and, as a result of the hollow spaces existing between the individual grains of the granulated material wetted by the binder, the covered substrate is not wetted by the binder in a proportion of 40 to 70%, preferably 50%. A second layer of water-emulsifiable synthetic resin including a hydraulic binder is applied to the hardened floor covering to achieve an increase in mechanical load which can be supported by the hardened covering.
