    • PURPOSE:To contrive smooth execution of work by a method wherein an attachment board is maintained with a specified distance kept from the wall surface by controlling a linear motor and a jig cylinder and moved for spraying primer to joints of the wall surface, and sealing material is automatically injected afterward. CONSTITUTION:A trestle 14 is moved toward the wall surface and positioned with a specified distance detected by a sensor 16 for maintaining the distance to the wall maintained, and primer is sprayed on detections made by a groove width measuring sensor 23 and a groove tracking sensor 24. The trestle 14 is moved again toward the wall surface after completion of spraying of the primer, and a sealing material is injected with a sealing gun 20 by similar operations. At the same time, a lift is elevated and the sealing material is put by pressure insertion into vertical joints of the external wall. When executing work for horisontal joints, the lift is moved transversely and spraying of the primer and injection of the sealing material are executed with similar equipment. A horizontal groove detecting roller 22 is provided to a sealing unit for vertical grooves, and injection to the vertical groove is suspended on a point where joints are intersecting each other.
