ABSTRACT OF THE DISCLOSURE Weather-resistant boards (for instance, particle boards, facade covering boards, and wall elements) and mouldings (for instance, containers, vessels, prefabricated building elements, and roof elements), are provided herein which are possessed of surface elasticity and pliancy by means of a permanently-elastic, covering layer. The base material is (a) an impregnatable porous base material, e.g. (i) a lignocellulose or other organic fibrous or particle material, or (ii) an inorganic fibrous or particle material; and (b) a vulcanized weather-resistant, outer resilient synthetic elastomeric material covering layer which has been vulcanized thereon in-situ at a temperature of at least 175°C. The vulcanized outer covering layer is bound to and is both adhered securely to one outer surface of the base material, and, when in unvulcanized form, has been penetrated into and impregnated below and into the same outer surface of the base material to be within the porous structure of the base material for only a predetermined limited region in the vicinity of the outer surface of the base material. Such weather resistant boards therefore consist of three layers. The first layer is an impregnatable porous, base material as defined above. The second layer is a vulcanized weather- resistant outer resilient synthetic elastomeric material covering. The third layer is the outer originally unvulcanized, resilient synthetic elastomeric material, which is penetrated and impregnated below and into the same outer surface of the base material to be within the porous structure of the base material and which is vulcanized therein in-situ. The board is an integral united material of the above-mentioned three layers.
