Abstract: Disclosed is a process for manufacturing elastic floor covering boards comprising a lower, water-permeable layer of natural or synthetic rubber particles bound together by an adhesive and a cover layer of non-woven synthetic textile fibers, which process comprises placing into a mold the cover layer of non-woven synthetic textile fibers, impregnating this layer with a resilient, heat-curable adhesive, placing the particles of natural or synthetic rubber which are likewise impregnated with said adhesive on top of the fibrous layer and subsequently compressing both layers in the mold at a temperature below 100.degree.C. and at a pressure of from 40 to 100 metric tons per square meter until the adhesive is cured. Advantageously, a woven reinforcing layer is interposed between the two layers prior to molding to provide an exceptionally strong and stable product.
