A multi-layer coating system for a body that forms a substrate or base for building material of the coating system, where at least one layer of coating system is a covering layer, comprises two-component epoxy resin which is sand-finished with hard granules; sandwich-like design having first base layer (2) that comes in contact with the body; and fiber-free and granule-free two-component epoxy resin; an intermediate layer that comprises flat random fiber non-woven material (3), and sand-finished top layer comprising fiber-free and granule-free two-component epoxy resin. Independent claims are included for the following: (1) producing a coating system on a body comprising a building material that forms a substrate for the coating system involving two-component compound that cures into an epoxy resin compound sprayed onto the surface of the body, and subsequently fibers are blown onto the layer, which still has low viscosity by compressed air, or sprinkled on it, so as to bond with the still uncured epoxy resin layer, where the epoxy resin layer is cured by way of cold and/or hot curing, a second two-component epoxy resin compound is applied in a low-viscosity state, so that the layers bond to each other by way of the epoxy resin penetrating into the random fibers in the low-viscosity state and cured, and the top layer is sand-finished at the exterior; and (2) coated building board comprising substrate, which includes rigid plastic foam having a base layer applied to one side that comprises a cured epoxy resin compound bonded to a random fiber layer, in which the layers have been bonded to each other by way of the epoxy resin penetrating into the random fiber layer in low-viscosity state and cured so as to form top layer provided with sand-finishing at the exterior. |
