Hi, I think grout pens re-colour existing grout, like a paint? I think you will have to use grout to fill the gaps.

Depending how many gaps you have you could look at getting one of the squeezy tubes of pre mixed grout that has a piping type nozzle. This would allow you to apply it where needed much more accurately and then just remove any excess by running a finger over the lines.

That would be great @whirlligig, will have to check out if our local DIY store sells them

Most DIY stores sell something similar but this is what I used to fix and blend in a couple of replaced tiles from where a radiator had been moved. Worked great - only downside was it made the rest of my grout look dirty by comparison! You shouldn't have that problem at least :).

I'd mix up some more of the same grout. Mix it to a smooth, creamy paste (add water to the powder not the other way around) and use a grout float.

This is another one of those jobs that looks easy but there is a knack to it and it takes practice :)

Thanks @Fusion interior design, we did use a grout float first time round but I think the trouble was that the mixture was too watery. Will have to try again - practice makes perfect :)

:) consistency should be something like peanut butter or nutella....that's done it, I need to have a bit of toast now ;)

Good luck :)

Thanks everyone. We re-grouted yesterday using some pre-mixed stuff to make sure we didn't go wrong on the consistency and it was all still there in the morning, so looking much better! Just have to polish everything up and get rid of any random flecks of grout. Any more tips on tidying/polishing/finishing the tiles would be welcome too :)

Your kitchen is looking very nice.

we have just done ours but we used white tiles ... with grey grouting it looks great but as already mention you need patience :-)

don't forget to seal your grout now that it's in place.

Thats interesting Tony when you mean seal it ..... is this something you brush on ?

I didn't know about sealing the tiles either, thank you @Tony V! And thanks everyone for the further comments. I believe the units are Howden, @Julia Stennett, but they were already there when we moved in so not sure exactly which ones.

Yes thank you Tony ....I'll have to do mine as at the moment we are using cling film to protect it :-)

you don't need to seal the tiles as they are ceramic and the surface is non porous - the idea of sealing the grout is to make the cementitious compound more resistant to staining as it is porous.

Love the tiles - can't help much with the grouting advice but sounds like you've got what you need to succeed!

Yes it looks much better ... I'll put some shots of ours up soon

But if like me you are a good cook you are going to need to protect the grouting

otherwise all those gravy stain will ruin it in one fail-swoop.

We are using fling film as a matter of protection on the tiles and once the cooking has finished take it down and bin it ... I hope this helps

Thanks @whirligig, we used some pre-mixed grout and went over it all with a float, cleaning up the excess afterwards. Then once it had all dried, went round and scraped off any flecks etc. and polished it up.

Good tip with the cling film @maplecottage! We haven't made anything too messy yet, so we'll see how we go. Might get some sealer spray as it looks fairly easy to apply.

No Problem LV ....

If you are a member of Costco you can get a massive roll for all most the price of a normal roll in the super markets

Found the shots of the kitchen being tiled with grey grouting

Regards David

Very nice, and you've gone all the way to the ceiling, that's some substantial tiling work!

Yes it just finishes it off .... Even with beading around the window

I wanted to give it a French look if that's the word ?

Regards David
