2 LINING THE RABBET (see fig. 1)

Fig. 1.

1. Cut both the polyester film and the Bostik Web into strips equal to the measurements of the inside of the rabbet of the frame.
2. With the tacking iron set at its highest temperature, lay the polyester film over the Bostik Web, and bridging the rabbet of the frame, press the film and the web into the rabbet with the hot tacking iron. The heat of the iron will form the film to the rabbet.
3. Again with the tacking iron, fold over the excess film to the outside of the rabbet, and trim flush with razor blade.
