ABSTRACT:
The outside surfaces of a ski are made by treating a fibrous material with a compound based on phenolic resin and containing 60 to 80 mass percent of dry matter, said phenolic resin being curable at 100.degree. to 120.degree. C., whereupon the thus-treated fibrous material is allowed to stand at 70.degree. to 90.degree. C. for a period of time long enough for said phenolic resin to partially polycondense, whereupon said material is applied to the ski blank and the resultant intermediate product is exposed to the effect of a temperature ranging within 100.degree. and 120.degree. C. and a pressure ranging within 0.5 and 2.0 MPa for complete polycondensation of said phenolic resin to occur and for said fibrous material to firmly adhere to the ski blank at the same time.
