New and improved fungicidal grout compositions are disclosed having a Portland cement base with a halogenated aromatic dinitrile added as an active fungicidal ingredient. The dinitrile is first wet blended with an inert solid fungicidal carrier and a surfactant, then dried and finely divided into a powder. The powder is blended with the other dry ingredients of a Portland cement grout to form a grout composition which is ready to be mixed with water to form a workable mortar for the grouting and setting of ceramic tiles. The resulting fungicidal grout compositions have improved fungicide dispersion and prolonged leach-life characteristics.
