Abstract
Methods and apparatus are provided for finishing a composite floor. The apparatus includes a grouting pan configured to be affixed to the rotating head of a finishing machine. The grouting pan has a planar bottom surface and curved sidewall. Grouting pans are rotated over a prepped surface such that the curved sidewalls trowel the mortar onto the rough composite surface and the bottom surface which is in contact with the prepped floor forces the mortar into the surface voids.
