The Ardex Ardurapid A45 Mortar can be applied up to 20mm neat in isolated areas, but for economy Ardex Coarse Aggregate or 1/3 volume of coarse screeding sand can be added to the mix. For thicknesses over 20mm, and up to 50mm, for holes etc., an equal volume of Ardex Coarse Aggregate must be used. For localised thicknesses exceeding 20mm e.g. filling deep holes and wide cracks, incorporate an equal volume of 10mm single sized coarse aggregate in the mortar.
