A method for forming an abrasion resistant paper sheet for use in decorative laminates comprising the steps of:
- mixing cellulosic feedstock and water to form a cellulosic slurry;
- depositing said cellulosic slurry from a primary headbox onto a wire of a papermaking machine to form a web;
- mixing resin-encapsulated grit particles with water to form a resin-encapsulated grit slurry;
- depositing said resin-encapsulated grit on said web using a secondary headbox or a slot orifice coater after said primary headbox but prior to papermaking drying equipment;
- drying said web using said drying equipment;
- and
- winding said web to form a roll of abrasion resistant paper.
