ABSTRACT:
An adjustable, combination floor tile mortar and grout spreading device for applying bonding material at a predetermined thickness in a straight-combed manner, and for spreading grout between floor tiles. The device comprises a telescopically adjustable rectangular frame having a leading edge and a trailing edge and a pair of downwardly extending sides for containing bonding material. The rectangular frame is telescopically adjustable to various widths and can be fixed at a particular width depending upon the size tile for the given installation. In the mortar spreading configuration, the trailing edge incorporates a resiliently mounted downwardly extending trowel blade having a conventional trowel blade edge with either a saw-tooth or square-toothed shape. The trowel blade is adjustable such that the device may be used for spreading various thicknesses of bonding material. Bonding material poured onto the subfloor between the frame leading edge and trailing edge is spread by sliding the device across the sub-floor such that the trailing edge trowel spreads the bonding material uniformly. In the grout spreading configuration, the trowel blade is replaced by resiliently mounted first and second grout floats acting as squeegees for spreading grout into the gaps existing between individual tiles.
