Adhesive spreader

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.
