A tool for determining if a two piece grommet is properly installed is provided. The tool includes a housing having a button. The button is movable from an up position to a down position. In the up position, indicia is displayed indicating that the grommet is not properly installed. In the down position, indicia is displayed indicating that the grommet is properly installed. The tool further includes a cup gauge and a stroke pin assembly. The cup gauge is dimensioned to fittingly engage the cup. The stroke pin assembly includes a stroke pin and a movable support. The button rests the movable support. The actuation of a stroke pin displaces the movable part away from the button, allowing the button to fall to the down position.

The present invention relates to the installation of floorcovering articles on chemically abated flooring surfaces and the composite article resulting therefrom. More specifically, the invention relates to a process for chemical removal of mastic, putty and/or paste material from a flooring surface. The process includes applying abatement chemical to the mastic material on the flooring surface to soften the mastic material and cause it to physically separate and release from the flooring surface, removal of the mastic material and abatement chemical, and the subsequent application of a barrier coating to the flooring surface. The barrier coating reduces and/or eliminates the migration of residual abatement chemicals into floorcovering articles thereinafter installed on the chemically abated flooring surface. The resulting composite article is comprised of a chemically abated flooring surface containing pores, at least one abatement chemical in said pores, a polymer-containing barrier material, and a floorcovering article.
