Adhesive spreader

A spreader for use in spreading a bed of predetermined thickness of adhesive material on a prepared floor surface prior to the laying of tiles. The spreader comprises a rectangular planar portion (2) having a serrated lower longitudinal edge (4) and flanges (6 and 8) extending substantially at right angles from the transverse edges of the rectangular planar portion (2). The flanges provide a barrier allowing a mass of adhesive to lie in front of the serrated edge (4) and between the flanges (6 and 8) as the spreader is drawn over the surface of the surface to be tiled. As the spreader is drawn over the surface the adhesive flows under the serrated edge thereby providing an even application of adhesive across the full width of the spreader. A height adjuster comprising an adjustable gauge (28) is provided as is a handle (10) or elongate handle (50) for convenient use by the tiler.






What I claim:

1. A spreader tool for spreading a viscous liquid material over an underlying surface, comprising:

a rectangular planar portion forming a rear wall having a plurality of indentations along a lower longitudinal edge,

a pair of opposing side walls extending substantially at right angles from the rear wall,

wherein said side walls provide a sideways barrier for a mass of viscous liquid material lying in front of said rear wall such that as the spreader tool and viscous liquid material are drawn across said surface a supply of viscous liquid material is spread over said surface as it flows through said indentations, providing an even application of viscous liquid material across the full width of the spreader tool, and

a height adjuster device comprising a gauge surface adjustable up and down the height of at least one of said side walls such that when said gauge surface is located on a guide located adjacent said surface to be tiled, said spread viscous material having a maximum height which is a predetermined distance from said gauge surface.

2. A spreader tool in accordance with claim 1 wherein said side walls are shaped so as to maintain said rear wall upright thereby providing a level upper surface to said spread viscous material.

3. A spreader tool in accordance with claim 1 wherein said indentations are triangular in shape so as to provide a saw tooth upper profile on an upper surface of said spread viscous material.

4. A spreader tool in accordance with claim 1 wherein said height adjuster device is fitted to both said side walls so that the maximum height of said spread viscous material can be set for each side of said spreader tool.

5. A spreader tool in accordance with claim 1 further comprising an elongate handle pivotably connected to said spreader tool and movable so as to in a raised position allow viscous material to be placed between said rear wall and opposed side walls and in a lowered position is useable to draw said spreader tool across said floor surface.

6. A spreader tool for spreading a viscous liquid material over an underlying surface, comprising:

a rectangular planar portion forming a rear wall having a plurality of indentations along a lower longitudinal edge,

a pair of opposing side walls extending substantially at right angles from the rear wall,

wherein said side walls provide a sideways barrier for a mass of viscous liquid material lying in front of said rear wall such that as the spreader tool and viscous liquid material are drawn across said surface a supply of viscous liquid material is spread over said surface as it flows through said indentations, providing an even application of viscous liquid material across the full width of the spreader tool, and

wherein said rectangular planar portion forming said rear wall is formed by at least two parts which are movable with respect to one another to adjust the width of said spreader tool.
