Abstract
A device for determining the adequacy of a sealant between construction elements is attached to a source of compressed air whose pressure is controlled by a regulator. The device includes a cylinder containing at least one piston, the piston containing an air chamber and a plunger, the air chamber being in communication with a pressure gauge. The device also includes an armature having a first and a second end, the first end being attached to the cylinder, the second end having a flow valve and an air fitting in communication with the air source, the handle containing tubing as a means to conduct air from the compressed air source, the tubing being interrupted with a bleed valve. The device also includes a moveable tip such that the tip moves in the direction parallel to the axis of the cylinder, said tip comprising a wheel, a wheel bracket and a plunger shaft, the plunger shaft being attached to the plunger within the piston. In use, the operator holds the device so that the moveable tip presses against the sealant with constant pressure.
