The invention provides a method of treating a floor, such as with a curable epoxy resin-based system or another resin system. The method involves mixing together a Part A comprising a resin and a Part B comprising a hardener to form an activated multicomponent resin system. In certain embodiments, the activated multicomponent resin system has a viscosity in a range of 900-1,200 centipoise. The method further comprises mixing a Part C comprising particles into the activated multicomponent resin system to form a slurry, spreading the slurry over a floor to form a slurry coat, and allowing the slurry coat to cure. Before and after the slurry coat has cured, it has particles of the Part C distributed substantially uniformly throughout. The invention also provides slurry floor coats and floors bearing such coats, as well as methods for repairing such floor coats and floors.

Slurry floor treatment technology, such as curable epoxy resin-based systems, other resin systems, and related resin coat methods

Machines and methods for curing ultraviolet (UV)-curable coating materials. In one embodiment, the machine includes a UV radiation source having one or more lamps partially enclosed within a shroud of a curing head. The machine may further include a supplemental energy source located outside of the shroud. The supplemental energy source may illuminate an uncured area of the floor coating material that is beyond the curing head. In some embodiments, the supplemental energy source may reduce or prevent the partial curing of the coating material outside of the curing head resulting from stray UV energy.
