Abstract:
1. A method for the production of a flooring resting on a sub-floor, comprising: providing a first layer of binder on the sub-floor; spreading a first layer of aggregate material over the first layer of binder to bond the first layer of aggregate material therein; providing a second layer of binder over the bonded first layer of binder and first layer of aggregate material; spreading a second layer of aggregate material over the second layer of binder to bond the second layer of aggregate material therein, aggregate particles of the second layer of aggregate material being randomly oriented upon being spread over the second layer of binder and defining, with the binder material, an irregular upper surface; grinding the irregular upper surface to form a smooth upper surface; and prior to allowing the second layer of binder to set and prior to grinding, mechanically processing and reorienting the second layer of binder and 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 to form the smooth upper surface is reduced.
