Abstract

An adjustable, floor tile mortar and grout spreading device for applying bonding material at a predetermined thickness in an efficient 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 one embodiment, the trailing edge incorporates a 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 a first grout float and a second grout float acting as a squeegee is attached at the trailing end for spreading grout into the gaps existing between individual tiles.

Claims

1. A combination floor tile mortar and grout spreading device for spreading an even layer of floor tile mortar bonding material over an underlying floor comprising:

a frame having a leading end, a trailing end, and opposing downwardly extending sides defining a width;

a downwardly extending, telescopically adjustable blade pivotally connected proximate said frame trailing end and extending between said opposing frame sides, such that pivoting said blade raises and lowers a blade edge for spreading bonding material at a user selected thickness;

means for telescopically adjusting said frame width;

said opposing frame sides for containing a quantity of bonding material placed on the floor therebetween, whereby sliding said frame across said floor causes said downwardly extending blade to spread the bonding material in a layer corresponding to said frame width.

2. A device as recited in claim 1, further comprising means for anchoring said frame at a predetermined width.

3. A device as recited in claim 1, wherein said downwardly extending blade is a removably attachable notched trowel blade.

4. A device as recited in claim 1, wherein said downwardly extending blade is a removably attachable grout float.

5. A device as recited in claim 1, further including a second downwardly extending telescopically adjustable blade connected proximate said frame trailing end and extending between said opposing frame sides for removing excess grout, said second downwardly extending blade being vertically adjustable relative to the floor, said second downwardly extending blade being a removably attachable grout float.

6. A device as recited in claim 1, wherein said opposing frame sides include non-scratching skids attached thereto to prevent scratching the floor tile.

7. A combination floor tile mortar and grout spreading device for spreading an even layer of floor tile mortar bonding material over an underlying floor, and for applying grout between floor tiles set therein, comprising:

a frame having a leading end, a trailing end, and opposing downwardly extending sides defining a width;

a downwardly extending, telescopically adjustable notched spreading blade pivotally connected proximate said frame trailing end and extending between said opposing frame sides; and

means for telescopically adjusting said frame width, whereby telescopic adjustment of said frame width causes a corresponding adjustment of said spreading blade;

said opposing frame sides for containing a quantity of bonding material placed on the floor therebetween, whereby sliding said frame across said floor causes said downwardly extending notched spreading blade to spread the bonding material in a layer corresponding to said frame width.

8. A device as recited in claim 7, further comprising a telescopically adjustable stabilizer bar disposed on an outer surface of said spreading blade for preventing said spreading blade from bowing.

9. A device as recited in claim 7, wherein said spreading blade comprises:

a telescopically adjustable trowel blade having a notched spreading edge defining a plurality of bonding material combing teeth.

10. A device as recited in claim 9, wherein said trowel blade is vertically adjustable.
