  • Patent number: 7504129
    Abstract: In a method of producing a flooring, a sub-floor is coated with a first layer of binder. A layer of aggregate material is spread over the binder which is then allowed to dry or set so that the particles bond therein. A second layer of binder is spread out over the first layer of binder and aggregate material bonded therein. A second layer of aggregate material is spread over the second layer of binder. Prior to drying or setting of the second layer of binder, the aggregate material of the second layer is mechanically processed to drive out air and in order to orient the particles of the aggregate material so that these turn their sharp edges and jagged tips away from the top side of the impending flooring. Finally, the flooring is allowed to dry or set, whereafter it is ground flat and even.
