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 a 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 such that a grouted surface.
Claims31
A method for finishing a composite surface comprising:
- (a) spreading a mortar over a rough composite surface having surface voids to form a prepped surface;
- (b) rotating a grouting pan over the prepped surface, the grouting pan having a curved sidewall extending from a rotary head for troweling the mortar onto the rough composite surface and a generally flat bottom surface in contact with the prepped floor for forcing the mortar into the surface voids to form a grouted surface;
- (c) curing the grouted surface to form a cured surface;
- and
- (d) finishing the cured surface to form a finished surface.
A method for finishing a floor surface comprising:
- (a) affixing grouting pans to a finishing machine;
- (b) rotating the grouting pans;
- (c) spreading a mortar over the floor surface having voids;
- (d) contacting the bottom surfaces of the rotating grouting pans with the floor surface while the grouting pans push the mortar into the voids;
- (e) each of the plurality of grouting pans including a bottom surface and a sidewall surrounding the bottom surface;
- and
- (f) the sidewall including a tapered portion and a rounded edge portion formed between the bottom surface and the tapered portion.
A method for finishing a floor surface comprising:
- (a) coupling a grouting pan to an aggregate floor-finishing machine;
- (b) contacting a metallic bottom and a sidewall, both having circular peripheries, of the grouting pan to the floor surface, the grouting pan further comprising a compliant intermediate layer located on an opposite side of the bottom from the floor surface;
- and
- (c) rotating the grouting pan by the machine.
