Re colouring tile grout

On the left as you drive up from La Zenia towards Villamartin you will see Preyser, we got all our tiles adhesives and grouping from them when doing our floors and bathroom, they should be able to help you.

The easiest way to do it is to rake out some of the grout, then re-apply new grout. I always use Morcem Color, which is a really good grout and is available in a wide range of colours.

Ty :)  that’s the last resort we were trying to avoid taking any out as we have a large area to colour.   I have seen some grout dye on amazon if all else fails :) 

Ty tho.  

Ty will give them a go 😀

If I may add me advice for your consideration.

Firstly, I endorse Jim's advice, you MUST take out the old grout. YES... this is hard work, messy and time-consuming, but like with everything if you get a good base to work with then you are already ahead overall!

So, to make your life easy I would invest in an oscillating tool. I bought an expensive version (I use it a lot!)  but I know they are available from around 50€, maybe even less. I have even seen them in non-food sections in the likes of Aldi and Lidl. Obviously, the expense is relative to the amount out grout you need to remove. I would further recommend you stay away from using a Dremmel type device, the small size of the attachments can lead to running off the grout and across the tiles, leaving a snail trail of a scratch across the ceramic! (Just my opinion)

Once you have your grout out, vacuum before you wipe down with a damp cloth. This will actually make your life easier in the cleanup process! Back to having a good base to work with, ready for your re-grout.

You haven't mentioned if your tiles are floor or wall tiles, in the bathroom or not, so I would also make sure you buy the appropriate grout for your room/use type.

For the application and finishing of the grout, I would suggest you spend a few mins (or more if you have time) watching youtube videos of how to do it. It really is NOT difficult, it is, however, quite a time-consuming task.

I hope that all helps and please, do NOT just use a grout paint stick! Yes it will take you minutes, but it will look awful in a matter of a days/weeks (depending again on where the tiles are)

The final point Jim makes about colour is important too. People cannot believe it when I advise NOT to use white tile grout on the floor, even for in between white tiles (there is a caveat to that comment depending upon tile and grout size!) The moment a floor, which has white grout, is mopped... it has started the staining process, it will very soon look off white and dirty.

Always work safely, please at least wear a dust mask if you are using an oscillating tool to remove the existing grout... there is likely to be LOTS of dust!

Good luck with your project and maybe take before and after photos and post to encourage others to undertake the task!

Thank you for taking the time to give me your advice :)  it looks like we are going to have to take it all out ( floor tiles ).   Hubby reckons there is 300/350 linear meters of grout lines to do.  :(  might have to get some one in to do it as it needs to be done before we start buying furniture.   

Ty again.   

UKHandyMan4Hire, that's an excellent post. All I'd add to it is that once the new grout is dry, you could apply liquid silicone - commonly used for waterproofing. That will seal the grout and help to prevent it picking up stains.

Thank you Jim, happy to help
