606.24 MECHANICAL FIXING In mechanical fixing, TGSIs with a stem or spigot that protrudes into the substrate are used instead of TGSIs with a flat base. This method is ideal to retro-fit discrete TGSIs after the substrate has been laid or on an existing substrate. The mechanical fixing mechanism may be supplemented through the use of an adhesive. For mechanical fixing, drilling templates shall be used as a guide and correct diameter holes drilled into the substrate to the minimum depth specified by the manufacturer. must be thoroughly cleaned with a suitable cleaning agent Metal TGSI’s (eg; acetone) prior to installation.
