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.
Claims35
A grouting pan assembly for finishing a composite surface comprising:
- a plurality of grouting pans;
- a rotatable member configured to affix the grouting pans to a finishing machine;
- and
- each of the plurality of grouting pans including a bottom surface and a curved sidewall surrounding the bottom surface;
- wherein the curved side wall includes an angled portion and a rounded edge portion formed between the bottom surface and the angled portion such that an obtuse included angle is formed therebetween.
A grouting pan assembly comprising:
- (a) an aggregate floor-finishing machine including a moveable member;
- (b) a grouting-pan coupled to the member, the grouting-pan comprising:
- (i) a floor-contacting metallic bottom having a circular periphery;
- (ii) a side wall having a circular periphery;
- and
- (iii) a compliant intermediate layer located between the bottom and the member.
A grouting pan assembly comprising:
- (a) a floor-finishing machine;
- (b) multiple grouting-pans rotatably coupled to the machine, each of the grouting pans comprising:
- (i) a floor-contacting bottom having a circular periphery;
- (ii) a side wall;
- (iii) a hook and loop fastener;
- and
- (c) grout troweled to fill floor-voids by rotation of the grouting-pans.
