Want to learn how to grout tiles? It's actually a relatively easy DIY job that can freshen up your kitchen, bathroom or any floor or wall tiles in your home in just a few hours. It is also a way to get rid of mould-ridden and damaged grout.
So whether you are re-grouting a tired-looking splashback, or starting from scratch and in the final stages of laying new bathroom floor tiles, follow this simple step-by-step guide to how to grout tiles and get it right first time.
How to replace old grout
If you are working with the newly laid tiles you can skip this bit, but if you want to know how to re-grouting old tiles there are are few steps you need to know about. You will have to remove the old grout before you go in with the new stuff. For this you will need a grout rake and to work methodically removing the grout between each tile by moving the rake up and down all the gaps (B&Q make an electric grout rake that makes the job quicker or you can use a Dremel Multi Tool which is also powered).
Be patient and take you time so you don't damage the tiles themselves, and once you have removed the grout, clean up any dust and debris before you start the regrouting.
How to grout tiles
You are now ready to grout. Make sure sanitaryware is covered in sheets and protected. Taps and fixings nearby should be covered, too.
You will need:
Step one: mix your grout
If you are working with a powdered grout your first step is to mix it. We recommend using a bucket with a pourer for this. Follow the instructions that come with your grout to get the water to powder quantities right. If you are using something like caulking grout that comes pre-mixed you can skip straight to the next step.
Step two: start applying the grout in small sections
Work in sections for the best results. Pour, or squeeze, a small amount of grout on to the tiles and start working it into the gaps in the tiles using a grout float. Work in sweeping arcs, making sure the grout fills all the spaces.
Step three: clean the tiles
Once you have let the grout set for a few minutes you can start gently cleaning off the excess using warm water and a grout sponge or microfibre cloth. Be sparing with the amount of water you use as you don't want to wipe away the grouting in between the tiles. Make sure you change the water often too and keep your sponge clean. Wait 10 minutes and then go in and clean again, repeat this until your tiles don't look cloudy.
Step four: seal the grout
To make your grout waterproof you will need to seal it with grout sealer. Follow the instructions on the one you have picked as different brands and different types will have different application processes. Just be sure to quickly clean away any drips.
Step five: let the grout dry
All that's left to do is let the grout dry, again check the instructions on the grout you are using and go by the time they recommend. Once it is dry clean the whole surface again using water water and a microfibre cloth.
