method of producing a flooring and a flooring produced according to the method

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.

1 - 15 . (canceled) 
   
   
       16 . A flooring to be smoothed by grinding, comprising:
 a first layer of binder;   particles of a first layer of aggregate material spread over the first layer of binder and bonded therein;   a second layer of binder spread over the bonded first layer of binder and particles of the first layer of aggregate material; and   particles of a second layer of aggregate material spread over the second layer of binder and bonded therein, the second layer of binder and the second layer aggregate material having been mechanically processed, relative to a random orientation of aggregate particles of the second layer of aggregate material, to remove air and to turn at least some of the aggregate particles of the second layer of aggregate material so that a volume of the irregular upper surface needed to be removed by grinding to form a smooth upper surface is reduced.   
   
   
       17 . The flooring as set forth in  claim 16 , wherein aggregate material of the first layer aggregate material is randomly oriented. 
   
   
       18 . The flooring as set forth in  claim 16 , wherein the first layer of aggregate material and the second layer of aggregate material are the same type of aggregate material. 
   
   
       19 . The flooring as set forth in  claim 18 , wherein the first layer of binder and the second layer of binder are the same type of binder. 
   
   
       20 . The flooring as set forth in  claim 16 , wherein the first layer of binder and the second layer of binder are the same type of binder. 
   
   
       21 . The flooring as set forth in  claim 16 , wherein the second layer of binder material covers upper surfaces of the particles of aggregate of the second layer of aggregate material.
