Method for manufacturing facing product for structural boards and facing products |
(57) This invention relates to a method for treating sheeted base materials containing
organic natural fibres or regenerated fibres. In the method, the base material, consisting
of a first side and a second side, is firstly treated on its first side using a liquid
treatment containing an antimicrobial agent and a binder. The base material is dried
and a layer containing wax is formed on the first side of the base material in a second
treatment, after which the layer containing wax is absorbed into the base material
at temperatures of 100-145 °C. This invention also relates to the treated base material
and to its use.
