Ready to use grout

[Galsandpals]

Does anyone have any recommendations for a ready to use grout.
my bathroom is in overall good condition apart from some grout coming away from walls.
Would like to repair myself as doesn’t seem a big job for a tradesperson

Thanks

I've done this. It is easy. I just bought the one in B&Q that was the same colour. It worked really well and looks a lot better

Thanks, was it a certain make or just b&q brand?

I used the Unibond one.

Thanks
ive ballsed up already. The scraper thing I bought has scratched my tiles and the grout I bought ( before your recommendation) says it need a primer 😥

You can just use a sponge to push the grout into the gaps. Then dampen the sponge and smooth out the grout.

It was trying to remove the old cracked grout I used the scraper with
