(54) Method and unit for producing highly abrasion-resistant protective coverings, in particular for floor and work surfaces


(57) There are provided a method and unit (1) for producing highly abrasion-resistant protective coverings, in particular for floor and work surfaces. The method includes preparing a mixture (3) of a powdered abrasion-resistant substance (4) (e.g. corundum) evenly dispersed in a polymer resin (5) suitable for subsequent polymerization and/or cross-linking; applying the mixture (3) to a substantially dry sheet material (7) (in particular, nonimpregnated paper or a dried preimpregnated material with a low wet residue); and drying the sheet material (7) coated with the mixture (3). Tests have shown the covering so formed imparts to the surfaces on which it is applied an abrasion resistance superior to that obtainable using conventional methods (e.g. in which the abrasion-resistant powder is applied, pure or dispersed in a resin, to a wet preimpregnated material).
