ABSTRACT:
A method of fabricating a concrete floor having an autogenous hard high gloss finish that does not require further coatings includes pouring a designed concrete mix to establish a slab having an upper surface slightly below the level determined for the finished floor. A finishing floor surface layer is created by applying an amount of a dry shake dressing material containing quartz crystals and a coloring agent, but no coarse aggregate, to the upper surface of the slab and floating the surface until the finishing layer reaches predetermined amount which cures to form a generally monolithic structure with the slab but having a higher compressive strength when fully cured. Necessary expansion joints are provided. The floor is coated with a curing sealer and allowed to cure for approximately 30 days, or until it reaches a predetermined compressive strength. The sealer material is removed and the expansion joints are sealed. The upper surface is then mechanically sanded and polished until a predetermined level of shine or gloss is achieved in the floor surface layer itself.
