A well-tiled surface - one that has been correctly prepared, hung, grouted and sealed - should give many years of service. Occasionally, though, a surface will be spoiled by discoloured grouting or a chipped tile. Both of these are very easy problems to solve.
Old grout can be quickly renovated with a renovation kit: liquid colourant, available in a range of colours can be brushed onto the existing clean and dry grout. Wash the tiles with sugar soap first and leave them to dry overnight. Paint on the colourant liquid and leave it for about an hour, then wet it with a sponge and wipe the excess colour away from the tiles. (The colour will adhere to the grout but not to the glazed tile surface.) These grout kits not only brighten up old grout but are also water-resistant once dry.
A tile that has a missing corner - often because it has been hit or has had something dropped on it - can be repaired by cutting a matching piece from a replacement tile. It's always a good idea to keep and store any leftover tiles from the batch just for this purpose.
