Pliable membrane installation tool

A tool comprising:

• a rigid horizontal planar body-base of a suitable length, width and thickness having on at least one end of the longitudinal axis of the body-base at least one extension of a rigid vertical planar element (prong) to provide support for at least one stay-wheel axle;
• at least one stay wheel with rotational freedom disposed on said stay-wheel axle;
• a handle integrally connected to the top surface of the body-base;
• a rigid cut-and-tuck horizontal planar member disposed on the top surface of said body-base adjacent to said handle;
• a cutting means connected to the cut-and-tuck horizontal planar member;
• a rigid vertical planar wall guide disposed on said cut-and-tuck member extended to one side of the longitudinal axis of said body-base to define a cutting slot;
• at least one tucking wheel with rotational freedom disposed on said wall guide;
• at least one guide wheel disposed on said wall guide adjacent to said tucking wheel whereby when said body-base with said wall guide is placed on top of a pliable membrane surface to be installed on a sub-floor surface with excess membrane curved up the wall, and the edge of the excess pliable membrane inserted into the cutting slot, the outside surface of said wall guide is contacted or nearly contacted to the wall and the tool pushed with force along the wall, the stay wheel stays, the guide wheel guides, cutting means cuts and tucking wheel tucks the cut edge of the pliable membrane to accomplish a finished installation of the edge of the pliable membrane in one trip along the wall.
