Although they make up such a small amount of a bathroom or kitchen’s space, those thin lines of grout between your tiles can have a substantial impact on how your room looks.

Stubborn dirt, grime and black mould can start to take hold regardless of how thoroughly you clean them.

Over time, grout can even start to dehydrate and crack, leaving unsightly gaps that could loosen your tiling.

Thankfully, if you’re not yet ready for a complete renovation, regrouting can give tiles a new lease of life.

With this in mind, we’ve put together this brief guide on how to regrout tiles. This relatively straightforward DIY job can make spaces feel that bit fresher.

We’ve even recommended a few special regrouting products for those wanting to do a tip-top job.

How to Regrout Tiles

You’ll Need

  • Dust Sheets
  • A Vacuum Cleaner
  • A Grout Rake
  • A Flat Head Screwdriver
  • Eye Protection
  • A Trowel/Grout Spreader
  • A Quality Tile Grout
  • A Cleaning Cloth/Sponge

1. Prep The Area - Although the job itself is simple, it’s can get a bit messy! Place your dust sheets down to cover the area beneath the wall you’re regrouting. Get your safety glasses on and your gloves at the ready.

2. Removing The Old Grout - With your gloves on and your eyes protected, take your grout rake and slowly score along all of the grout lines, removing the pieces of grout as you go. Once you’ve got familiar with the force required to use your rake, feel free to up the tempo!

3. Removing Stubborn Bits - After a number of passes with your grout rake, you should have removed the majority of grout between your tiles. For the stubborn bits that remain, we recommend taking a small, blunt flat-head screwdriver to chip away at them with minimal force. Take this step slowly, being careful not to chip your tiles.

4. Clean Up - Before you start regrouting, it’s best to do a quick clean up. Use your vacuum cleaner along the grout lines to remove any lingering dust. Then, grab a slightly damp cloth or sponge and give the entire wall a good wipe down.

5. Apply The Grout - Once the wall is dry, take your grout spreader and use it to liberally apply your chosen grout to the wall. Spread it using diagonal strokes to make sure it fills all of the lines evenly. Work quickly and don’t be afraid to use too much - you can always sweep up any excess with a clean damp cloth.

6. Wipe Down Again - After you’ve completed the entire wall, let the grout sit for 2-3 mins. Once again grab a clean, slightly damp cloth or sponge and wipe the entire tiled wall.

7. Finishing Up - Leave the grout to set for around 45-60 mins before using a dry cloth to scrub off any grout residue to neaten up your finished tiles. You can clean up the surrounding area in the meantime, vacuuming the floor of any bits that may have got through your dust sheets.

What About Regrouting Floor Tiles?

When it comes to regrouting floor tiles, the process is largely the same. However, you will need to take into account the space you need to work.

If regrouting floor tiles, start from the area furthest away from the door and work backwards in sections towards it. This will eliminate the risk of you stepping on and ruining those perfect grout lines!
