How to regrout tiles video
You will need:
A grout raker
- Waterproof grout
- A notched grout spreader
- A damp sponge
Cracked or grubby tile grout not only looks unsightly, it can also pose serious damp problems if water starts seeping behind your tiles. It's a time-consuming job, but tackled methodically, regrouting is a cost-effective way of smartening up your bathroom without resorting to retiling. Here's how to go about it...
Time to complete the job: An hour per m2 of wall, plus drying time
Approximate budget: £25 per 10m2 wall
Step 1: Rake out the damaged grout
Drag the grout raker down along the line of grout you want to remove. It's likely that you will need to apply some pressure so be careful not to slip and scratch the face of the tile. Be patient and take your time.
Step 2: Clean the tiles & gaps
Brush away any tile debris, soap scum or dirt from the raked-out areas to create a clean surface for the application of the new grout.
Step 3: Apply the new grout
Using the grout spreader, spread the grout into the raked-out cracks, pushing it in until all the spaces are full. Run the spreader across the surface of the tile to remove as much of the excess grout as you can. Wipe off the rest of the excess with a damp sponge until the tiles are virtually clean. Be careful not to remove the fresh grout in the cracks.
Step 4: Drying & finishing
Wait for the grout to dry and then using a clean, wet sponge, wipe over the tiles to remove any leftover streaks.
If the type of grout you're using does not contain a sealant, you will need to brush one on a few days later.
