PROBLEM TO BE SOLVED: To provide a hammer tone-coated building board which exerts excellent abrasion resistance by preventing an intermediate coating film presenting a hammer tone pattern from being affected by the abrasion of a top coat layer, even if the top coat layer is worn. SOLUTION: This hammer tone-coated building board A presents the hammer tone pattern by intermediately coating the top of a formed undercoating film 1 with a hammer tone paint which contains an incompatible component lacking in affinity with other paint components, and a rigid inorganic particle material 4, after undercoating is applied to a surface of a building material. After the formation of the intermediate coating film 2, top coating is applied, and a top coating film 3 is provided as a layer. Preferably, the incompatible component lacking in the affinity with the other paint components is a silicone-based water repellant, and the particle diameter of the rigid inorganic particle material 4 is set within 0.5-100μm.
