Regrouting tiles is a very effective way of reviving the look, and more importantly, the water repellent properties of a tiled surface. Grout will deteriorate a lot quicker than the tiles themselves and so within the lifespan of a tiled surface, you can expect to do some regrouting at least once or twice in order to keep things looking good as well as being water resistant.
|1. Rake out the old grout along all the joints, using a grout raker. Take care not to damage the edges of the tiles when scraping the joints.|
|2. Brush out all dust and debris from the joints with a dusting brush, or ideally use a vacuum to make sure that all the old loose material has been removed.|
|3. Mix up or apply ready mixed grout to all the joints, pressing firmly in place with a grout spreader (float). Work the grout in all directions along each joint.|
|4. Remove excess grout with a clean damp sponge. Keep checking for any small holes in the grout and refill if necessary.|
|5. Just as the grout begins to harden, use a grout shaper along the joints. Allow to dry before polishing with a dry cloth to remove any residue.|
- Raking out is not a quick job, but it is the only effective way of restoring tiles to as waterproof a surface as possible. One other option is to try a grout cleaner. As the name suggests, you simply apply and then wash off. Not perfect, but certainly makes a difference!
