摘要

To easily remove a base conditioner and an elastic coating material at a surface side which are applied to a surface of a building and at least one of which contains a harmful substance without scattering the harmful substance.SOLUTION: When a base conditioner 3a and an elastic coating material at a surface side which are applied to a wall surface 2 are removed, a worker turns a recovery separation tank 130 and a pressure tank 131 into independent states by using a partition mechanism, attaches a grinder part to a through hole of a case 121, and grinds the elastic coating material with the grinder part to remove the elastic coating material while suctioning the interior of the case 121 through a suction hose 125 by using a vacuum device 50. Next, the worker turns the recovery separation tank 130 and the pressure tank 131 into a communication state by using the partition mechanism, attaches a nozzle 122 to the through hole of the case 121, and sprays an abrasive material 111 to the base conditioner 3a, which is exposed by removal by the grinder part, from the nozzle 121 to remove the base conditioner 3a.SELECTED DRAWING: Figure 3
