The invention relates to a tool (10) intended to imprint a raised pattern on a coating, notably a coating applied to a wall, a floor or ceiling, comprising a die (20) equipped with a front face (20a) comprising a working surface (22) with a raised pattern (24) intended to come into contact with the coating, and gripping means. According to the invention, the working surface (22) has an overall curvature in at least a first rocking direction (XI) and the gripping means comprise at least a first and a second gripping zone which are spaced apart in said first rocking direction (XI), as a result of which the tool (10) can be rocked on the coating by the application of a variable force to the first and second gripping zones.
