Disclosed is an apparatus for applying a powdery or liquid material, comprising a pressure discharging device (12) with a compressed medium discharge connection (16), and an essentially small tube-type applicator with an upstream section that is to be connected to the compressed medium discharge connection (16) and a downstream discharge port (24) for the powdery or liquid material. According to the invention, the applicator (20) has at least one reservoir (54) for the powdery or liquid material and at least one valve. The powdery or liquid material can be discharged via the discharge port (24) with the help of the compressed medium once the valve has been opened.
