Apparatus for coating a lapping plate platen, and related methods of using

An apparatus for coating a lapping plate platen, wherein the apparatus comprises:

• a container having a capacity to contain a first volume of an aqueous composition, wherein the aqueous composition comprises:
• a solid resin powder,
• a plurality of solid abrasive particles, and
• an aqueous carrier;
• and
• a spray nozzle device in fluid communication with the container so that a second volume of the aqueous composition having a viscosity can flow from the container to the spray nozzle device due to gravity;
• a mounting device configured to mount the lapping plate platen, wherein the spray nozzle device is configured to spray the second volume of the aqueous composition onto the lapping plate platen to form a layer of an aqueous composition on a surface of the lapping plate platen.
