A method and a porous article are provided. In said method, a porous article which comprises a matrix material in a solid state and pores therein, is processed at least some of the pores being open to an outer surface of the article. A flowing treatment substance is applied to the outer surface of the article and into at least some of the pores. The flowing treatment substance is allowed to react with the outer surface of the article and surfaces of said at least some of the pores such that a hydrophobic coating layer is established on surfaces thereof. An excess of the flowing treatment substance is removed from the article, and the hydrophobic coating layer established on the outer surface of the article is converted into a hydrophilic coating layer.
