How do I fill holes before tiling?

Before tiling, localised holes and cracks in concrete, sand and cement screeds, steps and window returns, together with gaps around pipework and fittings, should be made good using ARDEX A 46 applied with a steel trowel. It will dry in as little as 4 hours, and can then be tiled as normal using an appropriate ARDEX Cement-Based Tile Adhesive.
