A laminar, synthetic resin floor construction especially adapted for roller rinks is provided which resists significant cracking, peeling or delamination characteristic of prior floors of this type, and has a useful life far in excess of such conventional laminated floors. The floor includes a relatively thick, high solids content epoxy primer layer applied over a porous substrate such as acid etched or sandblasted concrete, a thick epoxy resiliency or padding layer applied over and bonded to the primary layer, and a multiple-coat finishing layer applied over the resiliency layer which presents a proper roller skating surface. In preferred forms the primer and resiliency layers are each formed using epoxy resin compositions so that the layers can strongly bond to one another, with the high solids primer layer serving as an effective moisture barrier and base for the resiliency and finishing layer. The preferred method of making the floor includes successively applying the primer and resiliency layers and allowing each to individually dry and cure, followed by spraying the finishing layer in crosswise applied coats in order to complete the floor construction.
