Hi all, going to be putting some 600 x 300 (9mm) porcelain tiles up on a jackoboard tanked shower wall what size notched trowel do I need and what would the usual grout line size be, thanks

Personally would use a 10mm square notch trowel, backbutter/skim the tiles also before fixing, standard on walls is a 2mm spacer but some tiles can be a bit sizey so you may need 3mm and a pack of wedges to give yourself some wiggle room..check your tiles before starting.

Thanks Andy for the info
