Patio Tile Grout

If they're at least 5mm you can use the paving compound, or Sika do exterior grouts for porcelain slabs, which are good for smaller joints.

Apologise apologies for slight hijack. We have a couple of fairly large stone slab patios & paths and the grout/mortar? is crumbling. 

Can we simply remove the loose bits & replace with the Sika Paving compound, or will it all need removing? 

it will look patchy and you typically find that if some areas have started to fail then the rest will start to follow shortly thereafter and you'll be constantly patching.  The recent developments in brush in (some are just hose down)  compounds will save many a knee as manual pointing was awful (though therapeutic!) but ideally you want to rake out all the joints and repoint them all in one hit. 

Brush in are usually water permeable aren't they? If he has porcelain he won't want that

No but might be suitable for badger and his stone patios.

My fault. 
I shouldn’t have piggy backed on OP’s thread. Didn’t realise there might be different solutions.

Hi, a couple of options are available brush in grout for when the tiles are laid on hardcore, or fugabella when on a concrete slab they are both good for outdoors. I
