Grout lines

[Millsie]

Hi. I'm after some advice please guys. I've priced a job and the customer has asked if they have to have grout lines or if so as small as possible. There large format tiles 900 +300 ceramic. Any advice would be greatly received. As always thanks.

Hi..

Wall or floor... ?

BS5385 recommendations are 2mm walls and 3mm floors.

 

[David - Tradetiler]

regardless of British Standards, I'd never recommend anything narrower than 1mm.

As Dave says!

I don't like to go lower than 2mm also, if the tiles aren't mm perfect, small joints might not be an option.

Thanks Bri I was thinking that the grout lines may help hide any variations in tile size.

Thanks to all who replied as always you've come to the rescue of a newby

if it's floor and walls, then i'd go with 3mm so you can follow the joint up the wall. personally wouldn't go less than 3 if you're working on a wooden floor, even with backerboards and especially with ufh.
