Best Tile spacer size?? Help

[Jakeferno]

Hello I've got 500x500mm black polished porcelain floor tiles to be laid on a concrete floor and wanted to know what was the best spacer size to achieve a sleek seamless look, also I'm thinking of going for black grout , any suggestions?? And best grout and adhesive to go for??
Thanks

hello and welcome
2mm will give you sleek look, adhesive something like mapei qeraquick, if you tiling kitchen then would go with kerapoxy 120 grout, you also will need to seal these tiles before grouting.
good luck with your project

if you are not regular user of kerapoxy you can get mapei Keracolor FF 120

Oh and a good adhesive, price isn't really a factor Just want something that will last years

You can seal your tiles with Lithofin FZ sealer
