Tiles can transform any space and make it look clean, fresh and modern. However, over time, the grout between tiles can crack, stain or start to look dull.

What Does Regrouting Mean?
Regrouting is the process of applying a fresh layer of grout over old grout lines. Grout is the material that fills the gaps between tiles. Its job is to keep tiles in place and stop water and dirt from getting underneath.
When grout becomes discoloured, cracked or mouldy, people often think about full replacement. But today’s modern grout products allow you to Regrout Tiles without full removal in many situations.

- There are only small cracks or surface stains
- The tiles are stable and not loose
- There is no deep water damage underneath
However, if the grout is crumbling, deep mould is present, or tiles are moving, removing old grout is the safer option.

Step-by-Step Guide to Regrout Tiles Without Removing Old Grout
1. Clean the Old Grout Thoroughly
First, remove dirt, grease, stains and mould. Use a grout cleaner or a mix of baking soda and water. Scrub well and allow the area to dry completely.
2. Roughen the Surface Slightly
Lightly scuff the top of the old grout using sandpaper. This helps the new grout stick firmly.
3. Apply a Grout Bonding Agent (Optional)
This step improves adhesion and makes the finish last longer, especially in wet areas like bathrooms.
4. Mix the New Grout
Follow the instructions on the grout packet. The mixture should be thick but spreadable.
5. Apply the New Grout
Using a rubber float, press the grout firmly into the old grout lines at a diagonal angle.
6. Wipe Off Excess Grout
After 10–15 minutes, gently wipe the tiles with a damp sponge. Do not scrub too hard.
7. Allow the Grout to Dry
Let the grout cure for at least 24 hours. Avoid walking or using the area during this time.
8. Seal the Grout
Once fully dry, apply a grout sealer to protect against stains and moisture.
By following these steps, you can easily Regrout Tiles without professional help.
