Narrow Pointing tool for patio grout

Fogle1980

Hi, so we’ve done the hard part and laid our porcelain patio. The grout lines are 3mm wide and for the life of me I can’t find a pointing tool or similar online which will fit in the gap and give us a smooth finish. Any ideas greatly appreciated.

For smooth finish you can use any 3mm+ steel wire, e.g. a thick nail. Just bend it a little to make it easier to hold.

For filling the gaps - filling knife / plastic or metal or wooden rule / old bank cards (possibly 2-3 together) /...

Or check dental/scientific spatulas.

You need to grout porcelain slabs in a similar way to tiles. Use something like EasyGrout, which is a slurry designed for porcelain slabs. You finish them with a sponge float.

Any usable spoons?

If you're not going to grout them, but use a mortar mix the correct tool to get a compressed rounded joint is a 1/4 inch bullhorn jointer.
