In particular, the present invention provides hydrophobized fiber cement product, comprising a fiber cementitious matrix and a hydrophobizing agent uniformly dispersed therein, wherein said hydrophobizing agent comprises at least one hydrophobic silicone resin having a three-dimensional molecular network structure. The present invention further provides processes for producing a hydrophobized fiber cement product with enhanced water impermeability, wherein said process comprises at least the steps of: a) admixing an inorganic curable cementitious matrix with a hydrophobizing agent to form a curable mixture, wherein said hydrophobizing agent comprises at least one hydrophobic silicone resin having a three-dimensional molecular network structure, b) transforming the curable mixture into a shaped body; and c) curing the curable mixture to form a uniformly hydrophobized fiber cement product.
