Abstract: The present invention relates to coated fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides processes for manufacturing coated fiber cement products, these processes comprising the steps of: (i) providing a cured fiber cement product having at least one surface; (ii) optionally applying a primer to the at least one surface of the cured fiber cement product; (iii) providing a first layer of a first radiation curable composition to the at least one surface; (iv) partially curing the first layer of radiation curable composition by radiation; (v) providing a second layer of a second radiation curable composition to the partially cured first layer, the second radiation curable composition comprising pigments; and (vi) curing the first and the second layer of radiation curable composition by radiation. Finally, the present invention provides coated fiber cement products obtainable by such processes and uses of these fiber cement products as building materials. In particular embodiments, the coated fiber cement products produced by the processes of the present invention can be used to provide an outer surface to walls, both internal as well as external, a building or construction, e.g. as façade plate, siding, etc.
