An adhesive sheeting applicator and method adapted to dispense strips of adhesive-backed sheeting from a supply roll rotatably disposed thereon and to apply said strips of sheeting to a surface with a desired spacing between successive strips by advancing the applicator a distance along the surface, the sheeting on the supply roll being in successive cut strips applied to a continuous substrate liner. The applicator includes an application device for compressively engaging the adhesive of a strip of the adhesive sheeting to a surface commencing at a first end of the strip of adhesive sheeting and progressing to a second of the strip of adhesive sheeting as the applicator is advanced a distance along the surface and an adhesive sheeting spacing device for feeding a successive strip of adhesive sheeting from the supply roll to the application means as a function of the distance along the surface that the applicator has been advanced, whereby a desired spacing is achieved between successive strips of adhesive sheeting applied to the surface.
