Abstract: 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.
